@dling: Solar panels have efficiency of 10%, you can read it everywhere. That means that of energy received, 10% is converted to electricity, and 90% goes to universal energy sink, heat (and if you don't understand it, please read some physics 101). Think of it this way: you put solar panel, which absorbs almost 100% of solar light, somewhere, let's say on the desert ground, which usually reflects at least 30% (35% is usual number , and measurements in Sahara show 50%). So, instead of reflecting light back to space, solar panel converts it mostly to heat.
