I look forward to my eventual purchase of a Model S. Meanwhile I have been using my calculator. The home quick charger (double charger) supplies perhaps 80 amps, at 240 volts, correct? This means that the wattage supplied is 80*240 = 19200 watts. Each solar panel supplies 200 watts or better (maybe 250). SO how many panels are needed? This should be 19200/200 or roughly 96 panels. I hear people talking about a "break even" point of around 8 panels to fully charge a model S. How does that work? How does the "Roof" at a Supercharger site supply maybe 10 lanes? Is my math wrong?
