    That's bad :(:(
    When I was busy with solar panels some years ago the efficiency was around 10 to 12% for cristaline cells and around 8 to 9% for thin film cells.

    the 80% is 80% of standard solar panels

    That is what they meant. They are 80% efficent as compared to todays solar panels.
    The sun beats out thousands of watts of power per meter (I think around 2000 watts it was), so to capture 5% of it that would be 100 watts. 10% is 200watts. 80% is 1600 wattts. Thats alot of POWER!!!

    NOTE: The wattage would be for a meter squared solar panel, so one meter by one meter to get these wattages.

    So you mean only 4%? (assuming todays panels are 5%).

    Certainly nowhere near 80% of the light energy they receive! :p

    Yeah, I hope you know what 80% of 5% is :D :D :D

    One can find a lot of numbers on the net and in literature about "sunpower" ...
    Since insolation is different for all locations on the planet, the nominal power of a solar panel is given for a 1000W/m² insolation perpendicular to the panel.
    That sunpower you will get on the equator at noon :D:D
