How much energy do we use making solar energy panels?

    The exact amount differs depending on type and size of the photovoltaic panel, of course. The number to look for is the energy payback time. Back in 2000, it took 8-11 years for the panel to generate as much electricity as was spent making it, but this number is much smaller now, at about 1.5-3.5 years for crystalline silicon technology, and 1-1.5 years for thin-film ones. The exact number will depend on the placement, specifics of the panels (such as material) and supporting equipment.
