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

not really sure but you can check this....
