solar sizes …

after some googling’ one finds that you’ll need about 75-80 square feet for 1 kW … and the modules are at least $ 4.75 per W. some kyocera come rated at 26V 8A for a 200W module. more $ than i expected, but maybe the $ 3.75 was only the silicon. one should produce inverters etc, or mirrors that increase output without rotating the whole assembly, which is only good on a  flat rooftop!
