   this is not that easy. to see some results a lot of experimentation is required. go and do that by testing it under sun and noting the outout power at different times.

   Solar panels are too stupidly expensive at the moment. Thousands of £/$/€ to cover the roof of an average 3-bed home. There is news of a cheaper panel but not any time soon.

   Using a solar panel to provide domestic power requirements has been likened to filling a lake with an egg cup. Sadly, one decent size (and very expensive) solar panel will only provide enough power to light one standard light bulb

   Minimal, they require direct sunlight so must be moved or only useful for a lightbulb for two hours. Oil is used and has been favoured because it is the most efficient energy source. Oil is a natural resource, not a fossil fuel.

   Solar can’t replace all electricity generation any time soon, because there’s the problem of what to do at night. There isn’t a good way to store the energy.

   But that said, I think it’s very close to being practical for individual residences. We put in solar panels 2 years ago. It was not cheap – $12,000 – but it generates roughtly 100% of the kWh’s that we use each year. At that rate, it would take 20 years to break even. But the fact that it can break even at all is encouraging. And the price, while high, is not more than many people pay for a car. As a nation, could the USA come up with that kind of money? Well, if we took all the money we’re going to spend in Iraq, it would easily put a photovoltaic system on every family’s roof in America, for free. Not going to happen, but it gives a feeling for the magnitude of the number.

   One financial analyst [Cowen] predicts average selling prices of panels will drop 10-15% next year. Production is really ramping up.

   Alternate Energy is becoming a buzz word now that the fuel cost have gone through the ceiling with no relief in site,
   Supply and demand will bring the costs of panels down as time goes on. It’s always positive to keep your own energy usage down and with the addition of solar panels or wind generators at your home or business will decrease your reliance to the grid. The pay back equation is important but is somewhat over rated when the future of energy costs are so uncertain.

1. What do I attach my solar panel to so that I can read how much energy it was generated?

   This is for my science fair project, I'm comparing the energy gained with Wind and Solar. I have a solar panel but it didn't come with anything but alligator clips. What is something I can buy that would tell me how much Energy the panel has harvested? I was thinking something like a 12 volt...

2. How much energy can solar panel produce?

   I am doing a project on solar panels. All information given has to be accurate. May I know how much energy can monocrystalline, polycrystalline, amorphous, vaporware solar panel produce? I also want to know more about solar panels. For example, how did Americans use solar panels during autumn and winter? Is the solar panel used...

3. How would I run a light bulb off a solar panel?

   I am looking to make a demonstration using a large amorphous solar panel that I have lying around. I want to keep this as simple as possible. The solar panel that I have is a 96 Watt 12V solar panel. Thanks for any help or suggestions you can give me. Good for you...

4. How to use solar panel to generate electricity?

   Hi, I want to generate electricity using solar panel at home and I want to follow a simple tutorial. Could you recommend me a good tutorial? Photovoltaics are best known as a method for generating electric power by using solar cells to convert energy from the sun into a flow of electrons. The photovoltaic effect refers to...

5. If I had a solar panel hooked into the electricity grid and there was a blackout during the day?

   where would the electricity from the solar panel go? would it just heat up the solar panel until it explodes? That's a good question. When a grid goes down, and you're system is still supplying power to it, it creates what is called "islanding." http://en.wikipedia.org/wiki/Islanding Very dangerous. That's why inverters today are wired up with automatic anti-islanding circuitry built into them. It shuts down the...

6. How can I connect a solar panel to a power outlet to help power my house?

   I Have a small solar panel and Im not so sure about its voltage, so how can I connect it to some power outlet? And no; I am not thinking about using it to recharge batteries or directly powering appliances. This is done through the use of a grid tie inverter. The inverter turns the...

7. How would you connect a solar panel to a fan?

   I would like to connect a solar panel to a small fan. I am not sure as to what is needed to actually "connect" the two together. Any help is appreciated. Panels are rated nominally, and you can look at your fan to see what the ratings for the fam are to determine sizing of the...

8. How many watt solar panel do I need to charge a 12v battery that wont be using much electricity?

   1. The 12v battery will only be turning a small 12v motor that will be turning very slowly yet possibly or a long time. 2. 1-2 hours max per day it will be running 3. I want it to be fully sufficient on solar power once the energy in the battery runs out. What specifications for...

9. How to make a solar panel for my house?

   I want to learn how to make a solar panel to help lower my energy costs. Any recommendations on where I can start on my solar panel project? Thanks! Yes, it is possible to learn how to make a solar panel for your house. I was skeptical with all these claims about making your own energy,...

10. How to prevent shorting out solar panel?

    I have a solar panel I bought for a diy project and it has a small plug on the end of it, but I need to remove this plug to expose the positive and return wires so I can solder a bunch of stuff together. How do I cut off the plug without shorting out...
