Commercial Sector Drives U.S. Solar Market with 38 Percent Growth in Third Quarter, Solar Costs Continue Decline …
WASHINGTON & CAMBRIDGE, Mass.–(BUSINESS WIRE)–U.S. Solar Market growth continued in the third quarter of 2010 with 27,000 homes and businesses installing solar energy systems.
Are our scientists making solar panels all wrong??

Okay so.. if light deflect the light of the sun and black absorbs it, then aren’t solar panels just absorbing more light, sun and heat into our atmosphere? Wouldn’t this lead to an increase in global warming? Shouldn’t solar panals be white? No rude answers please.

To make electricity, the solar panel MUST absorb energy (heat and light) from the sun. Making them white would reduce the electricity they put out. The reduced electrical output would have to be made up by electricity generated by other means, which might include fossil fuels. A portion of the light and heat absorbed by a solar cell ceases to be heat or light; it is converted to electrical energy. A 100% efficient solar cell (one which converts all of the light and heat which hits it to electricity) would be absolutely black (no reflected light) and cold (all heat converted to electricity. Such a cell is not actually possible.
