Solar panels are expensive. In fact, next to the <a class="zem_slink" href="http://en.wikipedia.org/wiki/Rechargeable_battery" rel="wikipedia" title="Rechargeable battery">storage batteries</a>, solar panels make up the biggest financial barrier to most people converting to solar energy.</b><br />
<br />
Now, you don’t need batteries if you don’t want to store your <a class="zem_slink" href="http://en.wikipedia.org/wiki/Solar_power" rel="wikipedia" title="Solar power">solar generated</a> power to use at night and on cloudy days. But there is no way to produce solar energy without using solar panels.<br />
<br />
But what if you save a bundle of money by making your own solar panels? And what if you didn’t have to be an engineer or physicist to do it?<br />
<br />
Well, you can. And I am going to show you how it’s done.<br />
<br />
<b>Required Tools</b><br />
You probably already have most of the tools you need if you’re an average DIY person. Otherwise, between your local home improvement and electronics store, you can get everything you need.<br />
<br />
• Hand or electric wood saw<br />
• Soldering iron or gun <br />
• Paint brush <br />
• Rosin flux pen <br />
• Wire cutters <br />
• Screwdriver <br />
• Caulking gun <br />
• Volt meter <br />
• Plexiglas cutters<br />
• Drill<br />
<br />
Parts and Supplies<br />
<br />
• 3/8 or ½ outdoor-grade plywood (4x8 sheet)<br />
• 4/8 sheet of Plexiglas <br />
• Tin wire <br />
• Electrical solder<br />
• Silicon caulk <br />
• <a class="zem_slink" href="http://en.wikipedia.org/wiki/Ultraviolet" rel="wikipedia" title="Ultraviolet">UV-ray</a> protective varnish<br />
• Solar Cells (available online or at electronic supply stores)<br />
<br />
<b>Ready? Let’s get started.</b><br />
<br />
1. Calculate the number of solar cells you need by considering that 80 cells will produce around 100 watts of power under ideal sunlight conditions. You need around 36 cells to charge an 18 volt battery.<br />
<br />
2. Lay out your solar cells in rows and columns and then cut your plywood to a size necessary to support the dimensions you end up with. Most people use a rectangular layout, but that is not necessary. Use any layout pattern that works best with your roof and the number of solar cells you’ll be using per panel.<br />
<br />
3. Apply the UV-ray protective varnish to all sides of your cut plywood.<br />
<br />
4. Use the rosin flux pen to carefully apply flux to connector strips on each solar <a class="zem_slink" href="http://en.wikipedia.org/wiki/Battery_%28electricity%29" rel="wikipedia" title="Battery (electricity)">cell</a>. Then use your solder and soldering gun/iron to connect each cell together.<br />
<br />
5. Use dabs of the silicon caulk to attach the connected solar cells to the plywood panel.<br />
<br />
6. Drill two small holes to accommodate the two wires leading from the last solar cell in your array. Feed the wires through the holes and then seal the holes with silicon.<br />
<br />
7. Construct the frame that will support the Plexiglas and use silicon and wood screws to attach the frame to the plywood panel containing your solar cells.<br />
<br />
8. Pre-drill screw holes in the Plexiglas. Then apply a bead of silicon around the edges of the Plexiglas where it will contact the frame. Press down to make a tight seal and then screw in the wood screws. Do not over-tighten or you could crack the Plexiglas.<br />
<br />
9. Carefully inspect the assembled panel to make sure there are no gaps where moisture can enter. Seal any openings with silicon.<br />
<br />
10. Drill a small hole on the bottom of the panel, away from all the <a class="zem_slink" href="http://en.wikipedia.org/wiki/Electricity" rel="wikipedia" title="Electricity">electrical</a> connections, to allow air to circulate through the panel and remove condensation.<br />
<br />
Guess what? You’ve built a solar panel. Now that was easy, wasn’t it?<br />

<br />
Before I explain why solar power being expensive is a myth, I want to clarify that solar power is divided in two major areas that have to be treated as two different types of solar energy; thermal solar power and photovoltaic (PV) solar energy.<br />
<br />
First we are going to talk about solar thermal, which, without a doubt is not an expensive way too use solar energy in your house. Installing a solar thermal system for a typical home in America can cost you as little as $400, and the average return of the investment in a solar heater generated by the savings in your energy bill is less than two years. So, almost no one can say that this is too expensive for you to install. And even better, if you build the solar heater yourself, the system can cost you less than a hundred dollars.<br />
<br />
In the other hand we have the PV systems. In this case if you want to take your house completely off the grid only using solar power, it certainly will be a big one time expenditure. But, who says that you have to use solar energy in your entire house at once?<br />
<br />
You can start by buying your first PV energy kit for less than $400 in Costco or Lowes and start too see the savings in your energy bill in the first month. The trick here is too save this money in an energy jar so you can keep buying more and cheaper solar kits for your house using only the money you are saving with your solar panels; and before you notice it, you will be living in a house completely off the grid.<br />
<br />
So, as you can see, solar energy is not expensive, you only have to approach the issue with a new perspective.<br />

Solar energy is a renewable resource and of the oldest method of energy consumption that is available at present. One of the important facts about solar energy is that rays of the sun are so powerful that if we are to convert that into energy it would mean that Earth will never run out of energy for at least another 4.5 billion years according to scientists. The sun does not create any other hazardous by products which could harm the natural environment.<br />
<br />
During the early 1950s, facts about solar energy gave people a look upon this kind of power as an alternative to man made energy resources. Through much research it was found energy could be obtained at much cheaper source. The demand for solar power has grown substantially within the range of 20-25% over the last twenty years. Solar power is able to support household appliances, lighting and water heaters. As of the moment, solar power is more heavily priced but in the near future with the increase in scientific researches, it will bring down the costs and also increase its efficiency. Solar power is to generate 2.5% of the world's energy consumption by 2025. Energy power is the fastest growing technology.<br />
<br />
There are some basic facts about solar energy that one needs to be acquainted to; solar energy is measured in kilowatt hours and 1 kilowatt=100 watts. One kilowatt hour is equal to the amount of electricity which is required to burn 100 watt light bulb for approximately 10 hours. An average American household consumes 866 kilowatt hours per month. The Residential Energy Consumption Survey conducted in 2001 shows that an annual energy bill was around $2000 a month.<br />
<br />
A reduction in unit costs has contributed towards an increase in growth rates and thereby making it an important energy resource. Since 2000, one of the important facts about solar energy is that this type of power has been expanding at an incredible rate of 40% per annual. The energy generated from the sun is moving at a progressive rate in the developing countries too as the consumption of fossil fuel has doubled over the years. When compared to solar power which is unlimited, fossil fuel reserves are diminishing. Setting up solar power appliances is relatively easier in the more remote areas in comparison for setting up an expensive power grid structure. A disadvantage of fossil fuels is that the prices have risen together with the price of transporting coal, oil and gas.<div class="blogger-post-footer"><a href='http://solar-energy-now.blogspot.com/'>solar energy</a></div>Dr Hilhttp://www.blogger.com/profile/04901164718857818777noreply@blogger.com1tag:blogger.com,1999:blog-2616183537646968817.post-44162228822010998982009-11-20T22:32:00.000-08:002009-11-20T22:32:00.376-08:00Popularity of Homemade Solar PowerIn the present time homemade solar power is helping people to preserve electricity in an immense manner. Since electricity expenses are unsteady and escalating incessantly many house owners are undergoing the anxiety of finding another option. It will assist in minimizing power consumption to a good stage in addition to by chance lessen the information for the bills every month in addition to. Homemade solar power is a very good answer. Anyone may try to make use of homemade wind turbine to bring down cost of energy And everyone can employ additional options bringing down energy use in a dwelling. Straightforward rules that the capacity to aid someone subsequently but learning to make tools to construct homemade solar power acts a practical resolution. <br />

<b>Operation of Homemade Solar Panels</b><br />
<br />
It is very necessary to note the manner in which homemade solar panels are used. Home solar power panels do their job for generating electrical power with the help of a few sun light wavelengths. Ensure every part of the homemade solar panels receive fixed light of the sun for working in an effectual way. The device for solar power even entail less hotness. <br />
<br />
At the present time it appears less problematic than early days for making your individual gadget to generate solar power for homes because various modes of techniques and equipment you can get. Everyone’s individual homemade solar panels could give an effectual way to get personal solar power electricity. That is a great manner to save on upcoming power charges in your dwelling or even your car. <br />
<br />
<b>Homemade Solar Power Panel Crafting</b><br />
<br />
It appears simple for making an individual’s own panel to trap sun’s energy. Each and every constituent required to make a person’s own panel for solar energy can be availed with ease in the form of several supplies. Common components basically are a soldering iron, solar cells, solder, stuff for tabbing, and flux. Modern kits generally contain detailed steps on how any person can construct a solar panel. In your address no one requires assistance from a professional for building equipment supporting homemade solar power. That any person should execute is going behind all those uncomplicated procedures that any person gets with the device. All steps are simple for interpreting and implementing. You may look up internet debates for inquiring the persons who were able to create same kinds of solar panels earlier. A homemade solar power machine is a wonderful money saver. <br />
<br />
<b>Homemade Solar Power :Unproblematic Way Out</b><br />
<br />
In case someone desires additional energy production at that time he or she could bring in additional devices to produce extra energy. The government of USA in the year 2005 approved of a law interrelated with energy which accepted a 30% tax credit of the price of solar device coordination. <br />
<br />
The benefit of building and also fixing homemade solar panels is all panels look friendly with ecology. Many kinds of electrical energy scatter a lot of detrimental things which lead to air pollution as well as a mixture of smoke and fog however solar energy does not emit hazardous discharge. Homemade solar power provides a huge foundation for a form of power that is green.<br />

You have 1: the actual pump and 2: an energy source being powered by the sun, with a cable or wire connecting the two devices. Solar powered pumps can be used to pump water for humans, livestock or plants. Since the need for water is greatest on sunny hot days the technology is an obvious choice for this application.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://www.sun-pumps.com/images/Solar%20Powered%20Water%20Pumps.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="171" src="http://www.sun-pumps.com/images/Solar%20Powered%20Water%20Pumps.jpg" width="200" /></a><br />
</div>Pumping water using solar powered technology is simple, reliable, and requires almost no maintenance. <br />
To date the greatest use for solar powered pumps has been in agriculture where the pumps can be used on remote farms and outback stations to supply water to livestock. The remoteness is the key thing here as powering the pump by any means other than solar would be costly and inefficient. In a like manner, solar powered pumps are used extensively in developing countries to pump water from wells and rivers to villages for domestic consumption and irrigation of crops. <br />
<br />
A typical solar powered pumping system consists of an array of Photo Voltaic (PV) cells that powers an electric motor, which drives a pump. The water is often pumped from beneath the ground or from a stream into a storage tank that provides a gravity feed. No energy storage is needed for these systems (save from maybe a rechargeable back-up battery source). Solar powered pumping systems are a cost-effective alternative to windmills (particularly on still days) for remote area water supply.<br />
<br />
The most inexpensive solar powered pumps cost less than $1,500 while the larger systems can run to over $20,000. Most PV water pumps rarely exceed 2 horsepower in size. A well installed quality PV water pumping systems can provide over 20 years of reliable and continuous service.<br />
<br />
Whilst it has been the needs of developing countries and agriculture that has initially driven the demand for solar powered pump technology, a greater environmental consciousness around the world has seen many householders use solar powered pumps (rather than a less environmentally friendly internal combustion engine) to create solar powered waterfalls or solar powered fountains in a pond display. <br />
<br />
A solar powered pond, powered directly from solar panels, will work whenever there is direct sunlight; the brighter the sun the stronger the flow. Some solar powered water fountains will include a remote solar panel with enough wire that allows for the solar panel to be placed well away from the fountain. Solar power offers a great alternative when convenient electrical installation is not possible - as is often the case with gardens.<br />
<br />
Decorative additions to a solar powered pond display such as solar powered glowing frog lights and solar powered floating lily pad led lights can usually be purchased at the same place that you purchase your solar powered pump kit.<br />
<br />

And the distinction is important because the one thing that prevents many folks from enjoying the benefits of solar power is that they are afraid of ruining the appearance of their home.<br /><br />So what is the difference between a home equipped with solar panels vs. one with solar roof tiles? It is not hard to notice. Solar panels are those large, cumbersome units that often are perched atop the roof of a house, making it look to some people like something out of a science fiction movie.<br /><br />To install the panels properly, it is often necessary for additional roof framing or roof penetration. And if yours is the first house on the block to install solar panels, you might have to endure lots of funny looks and derogatory comments from the neighbors.<br /><br />On the other hand, solar roof tiles are much less obtrusive than solar panels. As the name implies, solar roof tiles are incorporated into your existing roof, whether it consists of asphalt shingles or most other common types. One shingle weighs about 2.5 pounds per square foot, so they are generally easy to work with when it comes to installation.<br /><br />They tend to be a dark bluish-gray in color, so they blend in easily with most existing roof types. And the best thing is that they provide for a seamless look, so the untrained eye will not be able to tell the difference.<br /><br />But perhaps the best thing about solar roof tiles is how they help you save on your energy bill. One tile puts out about 50 to 200 watts of energy, which is about as much as a small window fan. While this may not sound like much, if you incorporate the tiles into your entire roof, you should be able to supply enough energy for your entire house.<br /><br />And if you are fortunate enough to live in a sunny state such as California, Florida, or Arizona, you may even produce more energy than you need. You can then sell this excess energy back to the local power company, further reducing your energy costs.<br /><br />So not only do solar tiles look great, they'll help you do what's really important: save money.

Wind power, ethanol fuel, and solar power are among the top performers when it comes to alternative (and renewable) energy, and solar power in particular is being recommended by more converts to family and friends as the days go by. <br /><br />Currently, one of the best ways to utilize solar power is through solar panels. Roofs and other parts of the house pointing upwards are the best places to put your solar panels, so that you can get the most out of the sun's ultraviolet rays. Below are some of the many ways that you can benefit from using solar panels, roof or otherwise, and reap the rewards – starting today:<br /><br /><strong style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; ">Saving Money</strong><br /><br />It's no mystery that electricity bills are quickly rising in cost, due to the shakiness and instability of the present day global economy. Since prices on everything else are going up, electric companies have had to raise their prices to fight against inflation as well. The bad thing about this is that the costs aren't passed on to the consumer (you), and as a result you end up spending more on energy that really should only take a few dollars to produce. <br /><br />When you buy solar panels for home usage, you are investing in a form of energy that takes much less work to produce, provides actual renewable energy, and at a once in a lifetime cost (unless of course you need something repaired). This is a great deal for anyone, whether you consider yourself an alternative energy guru or not. It's just common sense.<br /><br /><strong style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; ">A Sleek Look</strong><br /><br />Once you get involved with solar panel construction, you'll see that it adds a whole new level of aesthetic appeal to your home. Your neighbors will be jealous that you're saving on energy costs, and the fact that you're house now has a sleek, cool new look that you otherwise wouldn't possess. Whenever I've seen a home decked out with solar panels, I always perform a double take because of how impressive and nice they usually look. When everything's said and done, solar panels just look cool. <br /><br />They also show that you're a person with a 21st century mindset, and understand that we won't be able to keep our current energy schemes up for very much longer. This ties in directly with the third benefit of using solar panels, roof or otherwise.<br /><br /><strong style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; ">Helping The Environment</strong><br /><br />Since you won't be adding to the potential energy crisis with over-consumptive tendencies, you'll be doing your part in helping the environment and saving the planet. I believe it's up to each individual to recognize their over-consumption, and to do something about it. We all play a part in the coming energy changes that are, without a doubt, taking place. <br /><br />When you buy solar panels for home usage and energy needs, you are affirming your role as a caring member of the human race. Solar energy efficiency is something that we all need to look into. By doing so, you've taken the first step in saving our planet from climate change and global warming.</span><div class="blogger-post-footer"><a href='http://solar-energy-now.blogspot.com/'>solar energy</a></div>Dr Hilhttp://www.blogger.com/profile/04901164718857818777noreply@blogger.com1tag:blogger.com,1999:blog-2616183537646968817.post-77785180544784070442009-04-18T07:01:00.000-07:002009-04-18T07:02:01.545-07:00Careers in Renewable Energy - Book Review<span class="Apple-style-span" style="color: rgb(75, 75, 75); font-family: Verdana; font-size: 13px; "><div id="body"><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">I just finished reading "Careers In Renewable Energy: Get A Green Energy Job" by Gregory McNamee. I've read almost every book that comes out on the topic of green jobs. I can say with conviction, that this is one of the best books available in the green career genre.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">We all hear about green jobs, but most people have no idea how to go about getting one. In this book the author will provide you with a roadmap to get involved in a career that makes a difference. All of the major components of renewable energy are covered, from solar, wind, and hydrogen. I really like this because a lot of other books that I read just focus on solar power.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">The best part of the book for me is the focus on college students and how they can begin preparing for a green career. The author outlines specific courses to take and different ways that students can strengthen their skill sets to be prepared to land a job in the renewable energy sector. The author also dives into many of the available resources on the Internet that can help, including the best jobsites to search for green jobs. This was very helpful because most students use the Internet these days to search for jobs.</p><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">My one criticism of the book is that the author almost completely ignores current workers. I think it would have been helpful if he had a chapter devoted to career changers and how one can transition into a career in renewable energy. <br />In closing, I would recommend this book to every college student that is looking to obtain a meaningful career upon graduation.</p></div><div><table cellpadding="0" cellspacing="0" border="0"><tbody><tr><td valign="top" style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; "><div id="sig" class="sig" style="font-family: Verdana, sans-serif; font-size: 10pt; color: rgb(75, 75, 75); margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; font-weight: normal; "><p style="font-family: Verdana, sans-serif; font-size: 10pt; font-weight: normal; ">Dan Keller is the CEO of the popular <a target="_new" href="http://www.greenjobscene.com/" id="link_83" style="color: rgb(25, 0, 255); text-decoration: underline; ">Green Jobs</a> site.

But these are both concepts that apply on a grand scale. It's very hard to equate what this means to an individual. We have to examine the past, present, and future of solar energy, in order to see that there is huge promise for the future of solar energy.<br />I, for one, could not have begun to tell you what the hard facts were in relation to solar power until I started digging. It turns out that what we hear about solar energy is just the tip of the iceberg. Which are disappearing, I might add, to the tune of 20% during the summer of 2008.<br /><br />A Brief History<br /><br />Before we go exploring the ins and outs of solar energy, let's take a look at how this force of nature has evolved over the centuries.<br /><br />Solar technology isn't new. It probably started some time in the 7th Century B.C., when people learned how to use glass and sunlight to light a fire. There is some evidence that ancient cultures across the globe have used glass and polished metals to concentrate the heat and light of the sun. This concept has been around so long that the Justinian Code of 6th Century A.D. decreed that every individual had "Sun Rights".<br /><br />Skip ahead several hundred years and you will find documentation detailing the construction and use of equipment that harnesses the heat and power of the sun.<br /><br />Solar Power Today<br /><br />Now that we know where we've been, let's look at where we are.<br /><br />Right now, all across our planet, governments and organizations are installing solar panels and contributing funds to further research into a renewable energy source that is hoped to rival conventional energy in the next decade.<br /><br />In the future, we can look forward to more solar energy homes and cars that perform up to the standards we expect from traditional fuel sources. Right this very moment I am living in a house that has solar panels to heat my water, and it does get very hot. I do, however, worry about having hot water at 2 a.m. Not that I take showers very often at that hour, but a writer's work isn't always done when the sun sets.<br /><br />Solar Timeline<br /><br />The following timeline for solar energy from the U.S. Department of Energy, lists the milestones in the historical development of solar technology from the 7th Century B.C. to now.<br /><br />* 700 B.C.<br />A magnifying glass is used to concentrate the sun's rays on a fuel and light a fire for light, warmth, and cooking.<br /><br />* 300 B.C.<br />Greeks and Romans use mirrors to light torches for religious purposes.<br /><br />* 200 B.C.<br />As early as 212 B.C., Greek scientist Archimedes makes use of the reflective properties of bronze shields to focus sunlight and set fire to Rome's wooden ships, which were besieging Syracuse. (Although there is no proof that this actually happened, the Greek navy recreated the experiment in 1973 and successfully set fire to a wooden boat 50 meters away.)<br /><br />* 20 A.D.<br />The Chinese report using mirrors to light torches for religious purposes.<br /><br />* 100 to 400 A.D.<br />In the first to the fourth centuries, Roman bath houses are built with large, south-facing windows to let in the sun's warmth.<br /><br />* 600 A.D.<br />Sunrooms on houses and public buildings are so common that the Justinian Code establishes "sun rights" to ensure that a building has access to the sun.<br /><br />* 1300 A.D.<br />In North America, the ancestors of Pueblo people known as Anasazi build south-facing cliff dwellings that capture the warmth of the winter sun.<br /><br />* 1700 to 1900 A.D.<br />Solar contraptions such as photovoltaic fiber, solar cells, and solar steam engines are invented. Eventually a water heater is power by solar electricity.<br /><br />* 1900s<br />Solar technology improved thousands of times over, with a vast array of solar materials and solar collectors being constructed and implemented all over the world. Entire towns are powered by solar energy by the year 2000. Buildings are constructed with photovoltaic glass and green roofs, and are self-sustainable thanks to the advancements is solar power conversion.<br /><br />* 2000s<br />Houses are powered with residential solar power systems sold in Home Depot, and NASA builds rockets and planes powered entirely by solar energy. Solar power is regarded as an inefficient possible solution to the upcoming oil issue.<br /><br />* The Future<br />Within 10 years, continued advances in solar technology will allow us to generate all the electricity needed to power the entire US, and photovoltaic power will be competitive in price with traditional sources of electricity.<br /><br />Solar electricity will be used in an electrolysis process that separates the hydrogen and oxygen in water so the hydrogen can be used in fuel cells for transportation and in buildings. <br /><br />Pros and Cons of Solar Power<br /><br />So this is where we must think about and examine the ups and downs of solar power.<br /><br />* First, the sun is free. Once you pay for your solar panels, you are done paying to power your home. Conversely, the sun does take a hiatus. Even so, you can switch to battery power to take up the slack if you want.<br /><br />* Second, if you have a system that produces more energy than you use, you can sell the excess energy to the utility company. But that usually requires you to live in a very sunny climate.<br /><br />* Third, the cost of maintenance is very low. Since it is just a flat panel that doesn't move, you don't have to worry very much about mechanical malfunctions. Unfortunately, the initial cost of these panels can be very expensive and serves as a deterrent to buying.<br /><br />I hope that these facts encourage you to look to the future of energy production. Environmental conservation is everyone's responsibility. We all do what we can. Hopefully sometime soon it will be more cost effective. We can scarce afford to lose the only habitable planet we have and some species, like the polar bear, are already losing.</span><div><span class="Apple-style-span" style="color: rgb(51, 51, 51); font-family: Verdana; font-size: 12px; line-height: 19px;"><br /></span></div><div><span class="Apple-style-span" style="color: rgb(51, 51, 51); font-family: Verdana; font-size: 12px; line-height: 19px;"><br /></span></div><div><span class="Apple-style-span" style="color: rgb(51, 51, 51); font-family: Verdana; font-size: 12px; line-height: 19px;"><span class="Apple-style-span" style="font-size: x-small;">The Energy Superstore was developed with a singular purpose: to enable residential, business and industrial customers to save energy in the most efficient and cost effective ways possible.

Today, you can do much more than simply buy lamps that run on solar power. Instead, you can generate your own solar energy, and use it to power every single conventional lamp in your home. In order to start reaping the rewards of harnessing solar energy, all you need to do is learn how to build your own solar energy generating system.<br /><br />Do you need a gradual plan to help you go "off the grid". Chances are, you feel like many other people that are taking their first tenuous steps away from commercial electricity. After all, who wants to be stuck in the dark, and without an electric company to blame? When you join solar power forums, you will meet hundreds of others who are dealing with the same fears and concerns.<br /><br />It is important to realize that you have nothing to lose by relying on solar power light and energy. That is, unless you are going to miss paying all those huge electric bills that sap your budget worse than a vampire having a midnight snack. Why go on living in fear, when you can embrace all the freedoms and rewards that come with harnessing solar energy? Don't you want to be a free citizen and enjoy all the good things money is supposed to buy?<br /><br />As you may be aware, even people that currently rely on solar energy were once in your shoes. They had to take all those small tedious steps that eventually helped them gain energy independence. Today, they are ready to help set you free of endless energy bills, as well as reliance on environmentally damaging commercial energy systems. While you are benefiting from their expert advice, you will also have an opportunity to interact with others that are going through the same process of liberation.<br /><br />Carl Ackerman is an expert on alternative energy and director of popular blog HomemadeEnergyForYou.Com.

Biomass energy is one such solution or is it?<br /><br />Biomass energy is unique in that it has existed in primitive forms since the early days of mankind. Burning wood in a cave is a form of biomass energy, which is simply the conversion of an organic material in a manner that produces heat. For example, a fire converts the organic wood into heat. Therein, however, lays the problem.<br /><br />Global warming is a much debated issue with everyone having a strong opinion and no one seemingly willing to listen to the other side. Whatever your view on this subject, what is clear is we are producing an absolute ton of carbon-based gases in our modern civilization. This is a key issue since the amount of carbon in the atmosphere is a key factor in climate regulation on our planet.<br /><br />To understand the problems of biomass as an energy form, one has to understand the biomass cycle that occurs on the planet. Simplified, the biomass cycle regulates the amount of carbon in our atmosphere. The biomass, primarily in the form of plants, uses carbon to grow and the biosphere effectively acts as a sponge for carbon. This sponge effect, however, has limits. As with a sponge in your kitchen, the biomass can only suck up so much carbon at one time. When there is too much carbon in the atmosphere or we shrink our “sponge” with deforestation and such, we run the risk of overwhelming the atmosphere with carbon gases. If our atmosphere has excessive carbon, heat is trapped and all hell begins to break loose. From a practical standpoint, this means our relatively mild climate on Earth will start becoming more chaotic. After the most recent hurricane season, that definitely is not a good thing.<br /><br />Taking the biomass cycle into consideration, the negatives of all biomass energy production are that they create more carbon gases. A caveman sitting next to a fire in a cave is using biomass energy to produce heat, but the black smoke is a very nasty carbon pollutant. In modern terms, biomass energy doesn’t really resolve the amount of carbon we are putting into the atmosphere. Yet, there is an argument on the other side of the biomass coin.<br /><br />Proponents of biomass argue it is a better energy source than fossil fuels. The basis of this argument is that plants [biomass] have taken in much smaller amounts of carbon gases over a shorter period of time than fossil fuels. Thus, burning them is a carbon neutral situation. The problem, of course, is that even if this concept is correct, we are not cutting down our carbon emissions. At this point in time, we need to be reducing carbon gasses, not maintaining our current output.<br /><br />It is undisputable biomass has its problems. It is a better alternative than fossil fuels, but how much so?<br /><br />Rick Chapo is with SolarCompanies.com, a directory of solar energy companies.

When a lower cost can be achieved, the benefits of mass production will cause a snowball effect in purchasing systems, and that time would seem to be drawing closer.<br /><br />Durham University in the UK, ever photovoltaic solar research project, with more than $12M to be spent in the next four years, starting in April. The principal investigator, Professor Ken Durose, has committed to "make a major contribution to achieving competitive photovoltaic solar energy". Nine industrial partners and eight institutions will be involved in the project, which is aimed at reducing the thickness, and thus cost, of solar cells.<br /><br />Much as this may seem to be a promising advance, an alternative approach is being adopted by commercial interests, in the form of a company called G24i which is also in the UK, in Wales. They have developed what are called fourth generation solar cells, which are a thin-film product, the latest buzzword in the solar marketplace.<br /><br />Their invention is a dye-sensitized solar cell (DSSC), which is, simply, printing a thin layer of titanium oxide on to a thin-film of metal foil, and then performing some molecular manipulations to achieve the desired reaction to light. The product is manufactured on a roll-to-roll process, similar to that used in the textile industry. They commenced production last year, and are planning to expand this year to a production capacity of 200 Megawatts.<br /><br />The process by which DSSC works has been compared to that of photosynthesis in plants, and it is more sensitive than conventional silicon cells, producing electricity from a wider range of the light spectrum and lower levels of lighting. It is very flexible and one-fiftieth of the weight of conventional glass silicon cells, and can even be produced in designer colors! The initial market is for devices that could not be made with the older technology, supplying power for portable electronics, particularly for mobile phones in the developing world.<br /><br />With a growth in the traditional solar cell market of 35% per annum, and a continuing global shortage of silicon projected up to 2010, G24i would seem to be very well placed to take away business from the conventional suppliers. Their technology is available at much lower cost, and expansion would seem to be limited only by their ability to grow in a controlled manner.<br /><br />On what seems to be a more esoteric front, it's reported that scientists are considering the possibility of a space engineering project that would dwarf any other that has been attempted to date. While the sheer size of the project would require governments to take the first steps at an international level, researchers from the USA, Europe and Japan are proposing building giant solar arrays in orbit and beaming the energy to Earth.<br /><br />Lieutenant Colonel Paul Damphousse of the Pentagon has spoken of the need for "hundreds of sorties every week" in order to move the tons of material that would be required. A recent study by the Pentagon concluded that such a project was nearly technologically possible right now, and that robots could be used to facilitate the construction in space. More realistically, perhaps, Leopold Summerer of the European Space Agency has projected that the generation of power in space may be about 20 years away, but the concept is being actively pursued.<br /><br />Finally, what may prove to be the most promising current development in solar energy has just been announced by Global Warming Solutions, Inc. of Houston. Successful tests have been conducted on hybrid solar modules, which produce both heat and electricity from one unit. The combined efficiency of the modules is reported to reach 85%, significantly better than the 40%+, then a record, achieved a year ago by Spectrolab using concentrator solar cells to produce electricity only.<br /><br />The technologies used include some originally developed for industrial lasers, stated Dr. Alexander Kornaraki, the COO. "The quantum pump separates the heat and the electrical photons of the incident solar light", giving the most efficient spectra to the photovoltaic process. The modules produce up to 28 Watts of electricity and 93 Watts of heat per square foot. The projected payback period is no more than five years.<br /><br />Global Warming Systems have several pilot systems, and one with 108 square feet of panels provides 100% of the energy, both electrical and heating, to a single family home. Even more promising, these panels are efficient even as far north as Alaska, which is a new achievement for the industry.<br /><br />Learn more about Solar Power and how you can use it to produce electric power, to heat, or even cool your home!<br /><br />Article Source: http://EzineArticles.com/?expert=George_Nikolaou<div class="blogger-post-footer"><a href='http://solar-energy-now.blogspot.com/'>solar energy</a></div>Dr Hilhttp://www.blogger.com/profile/04901164718857818777noreply@blogger.com1tag:blogger.com,1999:blog-2616183537646968817.post-48441343790011151812009-02-05T05:25:00.001-08:002009-02-05T05:25:26.615-08:00Negatives of Solar EnergyThese days green is the new black! That's right everyone across the United States are discovering new ways to save the planet by creating cars that release less toxic fumes, making new things from recycled materials, and by powering our homes in new ways. One of the more popular methods to living 'green' is through the use of solar power.<br /><br />Solar energy has the ability to give us cheaper if not free electricity to our homes through the use of solar panels. However, before you jump on the band wagon and go out and try to start this new power trip there are a few things you should know. There are some people who believe there are many negatives to solar power.<br /><br />Many people believe that thermal solar energy has many health risks when it is used to heat water and the air in their homes. This can happen when it has not been set up properly or the manufacturer made errors when producing it.<br /><br />Majority of solar water heaters were built to do three things. Give people hot water, obtain sunlight and convert it into heat energy, and to circulate the fluids that can transport heat energy to the storage system as well as store hot water till someone needs it.<br /><br />If it is unable to store the water properly it can cause fungus and molds to grow making anyone who drinks or uses the water sick. To make sure that this does not happen you can make sure that the units used to store the water have been built from materials that are made to prevent this.<br /><br />PV solar energy also as health risks that you need to be careful of. PV (photo-voltaic) panels require millions of silicon dioxide in order to be used. That number is lowered when they are exposed to heat. The materials that are released during the refining process will increase the rate of toxicity and can affect your health. This is one of the more serious negatives of solar energy that is responsible for eleven to twenty one deaths per each quadrillion joules of energy that are created.<br /><br />But do not let this deter you completely. Study up on the different types of solar panels and the negatives as well as the positives. You might find that they are worth it in the end.<br /><br />There are Solar Energy Benefits and Solar Energy Negatives that people will consider before they make a decision to install it. Learning how Solar Energy is Harnessed will help you to understand how it works.<br /><br />Article Source: http://EzineArticles.com/?expert=Naomi_West<div class="blogger-post-footer"><a href='http://solar-energy-now.blogspot.com/'>solar energy</a></div>Dr Hilhttp://www.blogger.com/profile/04901164718857818777noreply@blogger.com0tag:blogger.com,1999:blog-2616183537646968817.post-3509751636055993632008-12-25T01:51:00.000-08:002008-12-25T01:52:50.055-08:00Solar Panel Installation Procedure<img src="http://www.solarexpert.com/images8/pro-pool5.jpg" style="float:right; margin:0 0 10px 10px;cursor:pointer; cursor:hand;width: 288px; height: 216px;" border="0" alt="" />The process of solar panel installation is easy if you know what to do. A thorough understanding of the installation process helps home owners to choose the right devices and equipments to produce the most desired results. In this article, we’ll discuss solar panels and its installation process.<br /><br />Define: Solar Panels<br /><br />Solar panels are special devices capable of capturing the light emitted by the sun and convert the absorbed light into the electricity. Solar panels are the most important equipments of the solar power system. Therefore, one should always choose the highest quality of solar panels regardless of the selection of the installation process.<br /><br />Solar Panels Installation: The Process<br /><br />Once you have decided to install solar panels at your home or office, gathering relevant information is must. Educate yourself a bit to develop an understanding to choose the best to complete the entire installation process. Gathering information is important as different solar panel brands need to be installed differently. Also, the installation process of solar panels varies with their sizes. Hence, a good understanding is important while installing solar panels.<br /><br />You can hire a professional installer if you are not able to install the system of your own. Usually, installing the panel without prior experience is not safe as it could be a risky job to do. For example, if you are planning to install the solar panels onto the roof, you should be careful about handling the wires and other equipments used in the process. You may have to climb ladders and do such works, so prepare yourself or take the help of professional installers who holds some experience in the solar panel installation process.<br /><br />In general, solar panels are installed on a low pitched shingle or metal roof. However, many people prefer installing their panels on a flat roof..<div class="blogger-post-footer"><a href='http://solar-energy-now.blogspot.com/'>solar energy</a></div>Dr Hilhttp://www.blogger.com/profile/04901164718857818777noreply@blogger.com1tag:blogger.com,1999:blog-2616183537646968817.post-89999000089433719202008-11-03T07:26:00.001-08:002008-11-03T07:26:09.854-08:00Great Trends in Solar Panels and Solar Energy<br /> <p>The worldwide awareness and campaigning on the threat of environmental imbalance and polluted energy resources has made public opinion in favour of safe and clean environment . The corporate and industrial sector is not averse to cause of environmental safety. This is reflected from the new technologies for alternative use of energy resources. Solar energy is fast catching up as a most viable option of alternative energy owing to its non-polluting and inexhaustible nature. Solar panel is a wonder-tool in this concern which is unleashing a silent revolution which is visible in various spectrum and colours.<br /><br /> <strong>Retail Houses Up-link With Solar Energy </strong><br /><br />Now solar energy panels are not a object limited only to the vast farmhouses in the countryside. The great idea of adopting the eco-friendly and economical solar energy has already dawned upon the minds of big corporate houses. This is attested by the view of solar panels spotting the rooftops of retail house buildings. A substantial reduction in the energy needs cost is assured in case of business houses who welcome the solar energy. In addition to cutting down the tax bills , solar power is safe and human-friendly.<br /><br /> <strong>Solar Panels in Print Form </strong></p>
<br /><p>Now solar energy panels for harnessing the sunlight are also present in form of print sheets. This has been made possible by the efforts of Konarka Technologies in association with Massachusetts based research team. These panels have been framed on a technology analogous to the inkjet printing technology . Important thing is that these panels can be mounted on any surface or printed directly onto a surface . This innovation is going to make the solar panel a light weight and easy to install tool unlike those bulky and heavy frames of solar panels commonly found.<br /><br /> <strong>Solar Energy Powered Mobile Phones </strong><br /><br />Soon it will be unnecessary to rely on th electrical charging of the cellular phones. The solar panel meant for powering the functioning of the mobile phone is built on the straps attached to the mobile phones. Such type of technology is at present initiated by Strap ya company with brand name Solar Charge EC.</p>
<br /><p><br /><strong>Solar Panels to Power Space Vehicles</strong><br /><br />the latest state of the art technology research has made it reality to visualize the space travel without depending upon propellant fuel as energy source. The special purpose solar panels in this case are based on silicon fusion linked amorphous material. An alteration in the existing norm of propellant based spacecraft engine is mandatory along with the compliance with solar panel system. Air Force Research Laboratory (AFRL), New York reportedly have entered into a contract with United Solar Ovonic in this concern. Once completed the project will be a great step in direction of clean and cost-effective space travel for astronomical purposes and airships.<br /><br /><strong>Solar Panels on Fabrics</strong><br /><br />It is very interesting of thinking clothes enabled with solar panels for using up the sunlight around. With the concerted research work of Japanese scientists this is no less than a reality. The solar panel laden fabrics are based on extremely thin solar cell panel and render the properties like easily molding and colorfulness with equal aesthetic appeal as normal cloth.</p><br /> <div class="blogger-post-footer"><a href='http://solar-energy-now.blogspot.com/'>solar energy</a></div>Dr Hilhttp://www.blogger.com/profile/04901164718857818777noreply@blogger.com1tag:blogger.com,1999:blog-2616183537646968817.post-22141908580247892632008-11-03T07:25:00.001-08:002008-11-03T07:25:56.911-08:00Home Solar Energy Systems and the Photoelectric Effect (part 9)<br /> In the article that follows, we will explain in how a residential solar (PV) cell converts photons of sunlight into household electrical currents. This process is called the photoelectric effect. We will also explain the physical characteristics of how silicon moves electrons through various states to produce household solar electric power.<br /><br /><br /><br />Einstein was awarded the Nobel Prize in Physics for his work on the photoelectric effect, not for his work on relativity. Little did one know that the same people who helped us calculate everything under the sun is also the same person helping to bring renewable solar energy to the masses.<br /><br /><br /><br />Solar Electricity and the Photoelectric Effect<br /><br /><br /><br />The photoelectric effect is a key concept, since it is the way sunlight is converted into free electrons as light interacts with the solar cell. Without the creative work of Albert Einstein, the physical characteristics of sunlight might not be known. Never mind the impact and Earth-altering opportunities to power your home using solar generated electricity that his ideas inspired all these years later.<br /><br /><br /><br />Think of sunlight not as a wave but as a beam of photon particles for the purposes of explain the technical details of how home solar energy systems work. These bundles of energy penetrate the silicon lattice structure inside the solar cells making up a home solar panel and transfer their energy to an electron in the outer layer of the silicon atom.<br /><br /><br /><br />When a single electron gains enough energy from the penetrating photons, it breaks free and floats around the lattice structure, no longer bonded. An electron has a negative charge when it is knocked free during the photoelectric effect. The silicon atom that loses the electron, which had a neutral charge with the electron, now has a positive charge without it. Remember back to high school chemistry. Suddenly, these classes seem relevant when learning about solar generated electricity. Who would have known?<br /><br /><br /><br />When an electron is removed from this lattice structure or matrix in this fashion, it creates a hole in the outer layer of the lattice where the electron was. A nearby electron with a negative charge soon fills the hole. The electron that moves in has a positive charge. It can be described like the balancing of an equation; i.e. when one silicon electron consisting of a negative charge is transferred in...another particle, in this case an electron with a positive charge, is bumped out and moves out.<br /><br /><br /><br />As photons of sunlight penetrate the silicon and knock electrons loose they transfer their energy. Negative electrons are forced to move into nearby holes and positive holes appear where electrons once were. This photoelectric effect works because of the one-directional flow of positive and negative electrons. This flow of electrons produces the electrical current used in everyday use. The one way or single direction that the silicon electrons is produced when the sunlight, which is really photons of energy, repeatedly hit the silicon solar cells inside the PV panels making up the home solar power unit.<br /><br /><br /><br />Incredibly enough, this process is the secret sauce that allows electricity to be produced from ordinary sunlight. It is Albert Einstein's discovery, called the photoelectric effect, that makes solar electric energy possible. The average homeowner can now buy or rental home solar energy systems and generate useful electricity for their house.<br /><br /><br /> <div class="blogger-post-footer"><a href='http://solar-energy-now.blogspot.com/'>solar energy</a></div>Dr Hilhttp://www.blogger.com/profile/04901164718857818777noreply@blogger.com1tag:blogger.com,1999:blog-2616183537646968817.post-28142310999976936772008-11-02T01:17:00.003-07:002008-11-02T01:17:35.484-08:00Solar Contractors - How To Find A Reliable Solar Power Installer<br /> <p>It's not difficult to see the appeal of using solar power to meet our domestic energy needs: it utilizes a natural energy source (the sun) and thereby avoids any environmental damage that can result from the energy being generated via traditional means. The use of solar power for the home has become increasingly prevalent in recent years and particularly in dry landscapes that have an abundance of sunshine such as Australia or the state of California. For the majority of home owners however, installing a solar heating system without professional assistance is not a viable option. There are a number of things to consider such as adequate cable size, correct fusing (every circuit should be protected by a fuse or circuit breaker), the positioning of batteries and the correct positioning of the solar panels. Attempting to do all this by yourself and not getting it exactly right will result in a less than optimum performance of your solar power system. As such, it is prudent to call on the assistance of a solar power installer or solar contractor.<br />
<br /><br />
<br />The question that then arises is: "How do I go about finding a reliable solar power installer?" There is help at hand depending on where you happen to be located. The California Energy Commission maintains a list of registered installers on its Web site. California's solar rebates are available only to homeowners who use installers registered with the state, and all those contractors listed on the commission's Web site will qualify. You could also check the membership roster of the California Solar Energy Industries Association, the trade organization representing solar power installers. Similarly, homeowners in Oregon wishing to receive Energy Trust's incentives must have their system installed by an Energy Trust approved contractor. The Oregon Department of Energy maintains a list of tax credit-certified solar technicians. Many state-certified solar technicians are also Energy Trust trade ally contractors.<br />
<br /><br />
<br />In Australia, in order to qualify for the solar power rebate, the person who carries out the installation of the solar panels must be accredited for design and installation of photovoltaic systems by the Business Council for Sustainable Energy (BCSE). A list of BCSE accredited designers and installers is available from the Clean Energy Council - or alternately you could contact a designer/installer and ask for proof of their accreditation.<br />
<br /><br />
<br />As is always the case when dealing with any type of contractor, personal attention and responsiveness are important. If you find that one solar contractor seems to be able to communicate more clearly and is more responsive than others, you will probably want to take this into consideration when making your choice. Ultimately you want to be able to deal with a contractor that can design a system for your home, sell you the solar modules and install them. To do this you will need to find a contractor that has a good track record and a load of good references. The longevity of their business is also important as you'd want to be able to go back to the same installer in the future, should you experience any problems.</p><br /> <div class="blogger-post-footer"><a href='http://solar-energy-now.blogspot.com/'>solar energy</a></div>Dr Hilhttp://www.blogger.com/profile/04901164718857818777noreply@blogger.com2tag:blogger.com,1999:blog-2616183537646968817.post-28082774439463767692008-11-02T01:17:00.001-07:002008-11-02T01:17:26.103-08:00Solar Panels for Sufficient Energy for our Domestic as Well as Industrial Purposes<br /> <p>Solar Panels are the simplest form of technology for making the best use of renewable energy. The Sun is considered as the ultimate source for energy for all living forms on earth. <br />
<br /><br /><br />
<br /><br />As known widely, on a bright sunny day, the sun supplied around 1000 watts of energy on every square meter of earth’s surface. The most appropriate method to conserve fuel sources and yet produce sufficient energy for our domestic as well as industrial purposes is to collect this solar energy. Solar Panels are devices that collect and convert this solar energy from sun and convert into electricity and heat. <br />
<br /><br /><br />
<br /><br />The working of Solar Panels is very simple and easy to understand. The total structure consists of three major components namely Photovoltaic module, solar thermal collector and solar hot water panel. The photovoltaic cell in the Solar panels is responsible for producing electricity from sunrays. Alternatively, the thermal collector holds the sun heat and is used for heating purposes. The Solar water panel is a distinct mechanism that is used for water heating function in homes. To transform heat from sun light into usable forms, Solar panels employ modular array systems which are wired jointly in expandable design. Abundant exposure to sunlight and correct installation of Solar Panels is all that one needs to receive a free flow of electricity and reduction in huge electric bills at home. <br />
<br /><br /><br />
<br /><br />The inclusion of Photovoltaic(PV) cells and Solar panels in households and industrial set ups is a part of the solar revolution that has occurred all over the world since 2 decades. Latest research shows two different mechanisms to make use of solar energy. They are:<br />
<br /><br /><br />
<br /><br />Solar water heating collectors: These kinds of Solar panels absorb direct solar energy and utilize it in heating water.<br />
<br /><br /><br />
<br /><br />Solar electric or PV cells: such panels convert solar radiation into direct current.<br />
<br /><br /><br />
<br /><br />For maximum efficiency, it is advised to mount Solar panels on a roof that faces south at an angle of 30 degrees. The surface of the solar panels should avoid any shadows or objects that block its direct interaction with sunrays. Solar panels are a smart way to conserve household electricity and wastage of fuels hence producing required energy from the ever free warm rays from the sun.<br />

One area where it is being used with little fanfare is desalination of water.<br /><br />Removing Salt from Water Using Solar Power<br /><br />It is rather ironic that the majority of our planet is covered in water, but millions of people are in areas suffering from water shortages. The nature of the irony is clear almost immediately. The oceans of the world consist of salt water, a combination we simply cannot drink.<br /><br />For the longest time, there has been discussion about converting saltwater into usable, drinkable water. This process is known as desalination. If the process can be used on a large scale in a cost effective manner, it will resolve many of the water issues in the world today whether they exist in third or first world countries.<br /><br />Desalination is a term used for removing salt and minerals from ocean water. The name suggests one methodology, but there are actually many. Reverse osmosis is currently the most popular and is essentially a filtration process. It is popular in countries that currently have desalination plants such as those found in the Mideast and Caribbean. The process is also gaining more interest in China and the United States where certain regions are suffering habitual water shortages.<br /><br />One of the issues that arise with desalination is the energy cost. Most plants are powered by fossil fuels, although Russia is currently studying a plant run off nuclear energy. With global warming and energy price concerns on the forefront, many are now looking to renewable energy platforms as an energy source for these plants. Solar energy is one of the options.<br /><br />Solar desalination plants do not work in the way you might think. Solar energy is not used to provide power to the desalination process, although it probably could be. Instead, the power of the sun is built into the system. The idea is to heat saltwater and turn it into a vapor. The vapor is then run through a condenser system that turns it back into liquid water.<br /><br />Solar desalination systems work differently, but the idea is to separate the water from salt by using the natural system one finds in the oceans. As you probably know, water evaporates off of the ocean to form clouds in the atmosphere. When the proper conditions occur, these clouds subsequently turn into rain clouds and release the saltless water. Solar desalination tries to mimic the process.<br /><br />The double concern of rising energy prices and global warming are stimulating research in the renewable energy field. Solar desalination represents just one area where this research is producing tangible benefits.<br /><br />Rick Chapo is with SolarCompanies.com - a directory of solar energy companies.<br /><br />Article Source: http://EzineArticles.com/?expert=Richard_Chapo<div class="blogger-post-footer"><a href='http://solar-energy-now.blogspot.com/'>solar energy</a></div>Dr Hilhttp://www.blogger.com/profile/04901164718857818777noreply@blogger.com1tag:blogger.com,1999:blog-2616183537646968817.post-32898095115122076632008-10-18T03:54:00.000-07:002008-10-18T03:54:00.572-07:00Top 8 Solar Power Advantages<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://sustainabledesignupdate.com/wp-content/uploads/2007/05/nevada-solar-one-1.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer; width: 200px;" src="http://sustainabledesignupdate.com/wp-content/uploads/2007/05/nevada-solar-one-1.jpg" alt="" border="0" /></a>Solar energy is generated using the light from Sun.

The following article explains the terms associated with home electricity and defines the general electrical concepts found in residential solar electric systems. The majority of this article defines on the important terms, principles, and technical definitions that will be further explained in relation to home solar power in another article.<br />
<br /><br /><br />
<br /><br />The intent of this article is to help you to understand enough about electricity so that you can understand the technology used in solar photovoltaic (PV) systems. You most likely will review a lot of information and learn many new solar energy terms when you begin the process of purchasing or renting a home solar power system.<br />
<br /><br /><br />
<br /><br />When you start researching residential solar energy systems, or even taking a close look at your electric bill, you hear a lot about kilowatts and kilowatt hours. You may have used these terms mistakenly as the same thing in the past. The ideas are really very similar. Both terms are just a measure of relative electricity sizes.<br />
<br /><br /><br />
<br /><br />However, they are very different measurements, as you will learn through the electricity definitions included here. In order to understand what they mean, you also need to understand a few basic concepts about electricity.<br />
<br /><br /><br />
<br /><br />When talking about electricity, you will be using terms like power and energy. The average person often uses these terms interchangeably in daily speech along with current, potential, charge, electrons, and even photons. You might have learned about all of these electricity terms way back in high school. In use as part of your daily life, you may have confused their meaning.<br />
<br /><br /><br />
<br /><br />Common Residential Electricity Terms<br />
<br /><br /><br />
<br /><br />Here are the most important electricity concepts you need to know when you begin the process of purchasing or renting a solar energy system for your home. It may be surprising to you that the actual meaning of a few of these is not quite what you expected.<br />
<br /><br /><br />
<br /><br />Power: The rate at which work is performed or energy is provided. Power is the amount of energy required or expended for a given unit of time. It is measured in watts (W).<br />
<br /><br /><br />
<br /><br />Energy: The actual work done by solar panels installed on your home. In other words, energy is power supplied over a period of time. It is typically measured in joules or watt hours (Wh).<br />
<br /><br /><br />
<br /><br />Potential: The capacity of an electric field to do work (i.e. to provide energy). This is similar to the height of water behind a dam. It has capacity to do work. The higher the water, the more potential energy that is available. Potential is calculated and measured in volts.<br />
<br /><br /><br />
<br /><br />Current: A passage or movement of materials charged with electricity. This is not unlike the speed of water flow in a river. It is measured in amperes (I or in common terms amps).<br />
<br /><br /><br />
<br /><br />Resistance: The characteristic of a material, substance, object, or circuit to limit the passage of electricity. Items letting electricity to pass with low resistance are called conductors and materials that resist electricity from flowing are called insulators. Resistance is measured in ohms (R).<br />
<br /><br /><br />
<br /><br />Charge: A property of some subatomic particles, i.e. the charge on an electron (subatomic particle is negative). Charge determines how subatomic particles interact. Electrically charged matter is influenced by and produces electromagnetic fields. Having strengths that can be measured, a charge has two states; either negative or positive.<br />
<br /><br /><br />
<br /><br />Field: An effect produced by an electric charge that exerts a force on charged objects in its vicinity.<br />
<br /><br /><br />
<br /><br />Electron: A negatively charged subatomic particle. The current is caused by the movement of electrons from different energy levels within its atomic structure.<br />
<br /><br /><br />
<br /><br />Photon: An elementary particle that is the carrier of electromagnetic radiation of all wavelengths. The photon is different from many other elementary particles, such as the electron, because it has no mass. That means that it travels at the speed of light across the vacuum of space. Trillions and trillions of photons are blasted out from the sun every second.<br />

They take the light from the sun and convert the energy it contains into electricity which is made use to charge a battery. When it becomes dark a light sensitive switch initiates the solar light to come on. The light is powered by the electricity stocked in the battery and will continue to be illuminated until all the charge in the battery is used.<br />
<br /><br />
<br />This is uncomplicated in concept but the machinery required to make this come about is not so simple and only lately it has become promising to make solar lights that are small, efficient and economical enough to be affordable by the majority of consumers. Each light or set of lights will have a very small solar panel to catch the rays of the sun. The solar cells in the solar panel utilize the photovoltaic effect to convert the light they collect into electricity. Exclusive electronics then uses this electricity to charge the battery, which is mainly part of the solar panel or light unit.<br />
<br /><br />
<br />The solar cell is the most essential part of the technology used in all solar panels and it is repeatedly being studied to find enhanced and more economical ways to convert sun light into electricity. Over time this will definitely be improved upon and solar lights will then become much brighter and illuminate for much longer. The light sensitive switch and the electronics which manages the release of the battery's electricity are fairly standard components although over time they too will be superior to grant more efficient solar lighting for everyone.<br />
<br /><br />
<br />The solar panel, whether a separate mini panel or integrated into the light unit, must be installed so that it receives sun light during the day. If it is located in the shade it will not work. In spite of this the solar panels on most outdoor solar lights will now work on cloudy days though not quite as well as on a day with a clear sky. <br />
<br /><br />
<br />Science and technology and improved construction processes means that improvement of solar lights will continue far in to the future, so expect to see more and more innovative uses for solar powered lights particularly when the power and amount of the light beam is improved beyond what it is now. Whichever way you look at it solar powered lights are here to stay and will only get better with time giving us all the chance to light areas outside our home with zero electricity costs, which has to be a good thing.<br /> <div class="blogger-post-footer"><a href='http://solar-energy-now.blogspot.com/'>solar energy</a></div>Dr Hilhttp://www.blogger.com/profile/04901164718857818777noreply@blogger.com0
