Q:solar panels on housing developments?
Because not only does that just make TOO much sense, it comes down a cost factor, even though, as you say, what's another couple K for saving the environment. Sad thing is, even though they *JUST* figured out that global warming (loved that news story a couple weeks ago) is caused by humans abusing the earth, Americans especially just don't care enough. Our culture is so spoiled now that we refuse to be told what we need if it's not what we want or if it will cost us $5 extra.
Q:solar panel??????????????
The only real purpose of solar panels these days is to charge batteries - they just don't generate enough energy to do anything else and its dependent upon light levels - ergo you need the backup. Also - very expensive.
Q:How much was the price of solar panels 5 years ago compared to now?
I to register for free and lock in long term costs. The increasing demand and competition is helping reduce costs.
Q:how much is one solar panel?
no one has answered because you asked a question that cannot be answered. It is exactly the same question as how much is a car?. Do you want a passive solar heating panel, a solar electric panel, .5 Volts, ,000,000 BTUs, do you want just the panel or the panel installed and functioning, or what? the answer is between $5 and $5,000,000.
Q:How do Solar Panels work, and how it can generate electricity?
Solar under products that are sorted by watts per area. Also go to wikipedia to get more detailed information on solar cells.
Q:How many LED's can power a solar panel?
Q:information on solar panels?
A decent installation needs a solar engineer to make sure the panels are aligned to take advantage of all the solar it can get. that or You need to hit the books on solar radiation. online I would try different programs to get the feel. we get less solar radiating in the winter then in the summer. this needs to correctly compensated.
Q:2 Questions on Solar Panels?
Solar panels come in many kinds, using a variety of technologies and sizes, but the most common is still the crystalline silicon type. The power produced is variable, but the better ones you can buy approach 20% efficiency, and the peak energy from the sun is 200W/m^2 (Watts per square meter). This only occurs when the panel is lined up with the sun on a clear day with the sun high in the sky. The efficiency is also affected by how the electrical energy is taken from the panel, and the temperature of the panel. In the full sun the temperature approaches 60C, so the voltage drops. The links below provide a lot of information about such matters. A BP panel 50mm x 674mm gives a peak power of 20W. This is .07 square meters. As you can see this is very close to 20%. (The third link). However this is less in practice because the sun may not be full sun and may not be perpendicular to the panel. The output drops as the cosine of the angle to the sun, more or less. Even with peak sun this would produce only about 00W charging a 2V battery directly, unless an electronic Maximum Power Point Tracking (MPPT) charge control is used.
Q:Do solar panels steal sunlight from nearby plants?
if that were true, then anything that absorbs the suns rays do the same thing. Doesn't make any sense to me.
