Er, not quite a hijack, but as I have a garage, but no power supply would one of the following solar panels, (lifted from an old thread), be a workable solution mounted on the garage roof during winter?
"Two waterproof and corrosion resistant solar panels for outdoor use. The panels are weatherproof and resistant to wind, rain, humidity, snow, ice, sand, sea air and deterioration by ultraviolet light. These panels are intended to be used as battery chargers and lead acid battery trickle chargers. A reverse blocking diode is built in to prevent battery discharge and protect the panel cells. A tilt stand, made up from supplied parts, can be assembled and mounted on a vertical or horizontal surface, or can be free-standing, to catch the sun (screws supplied). Each panel is provided with red and black leads terminated in either insulated crocodile clips or car battery style clamps. The mechanical construction is extremely strong and able to withstand heavy weights.
