Question:

powering an imaginary city! (need solar panels!)?

What is the biggest solar panel you can buy?How much energy can it produce in kwh?Thanks :)

Answer:

come to tn
There are panels made up to about 250 watts. You string them together in series/parallel to get more power. Depending on your average insolation, a 250 watt panel caqn produce anywhere from a kwh/day to two kwh/day (averaged over the year - it's less in the winter and more in the summer and can range from 0 to three kwh/day). Powering a city also requires energy storage for nightime or cloudy days. The cost of this can exceed the cost of the panels by a factor of three. DK
Depends upon the technology, but keep in mind that biggest may produce the most output per panel but smaller panels may have a higher efficiency factor and so produce more per sq meter. Solar Integrated Technologies:SI-G 864 - STC 864W Thin Film Roofing Membrane - PTC 779.8 Watts ENN Solar Energy: EST-480 - STC 480W Thin Film Tandem Junction Module - PTC 440.6 Watts SunPower:SPR-445J-WHT-D - STC 445W Monocrystalline Module - PTC 42.7 Watts Topsun: TS-M420JA - STC 420W Polycrystalline Module - PTC 376.3 Watts
not really sure but you can check this....
