Unfortunately this is not the case. Normal grass, concrete, etc reflects most of sunlight back - therfore the case for greenhouse gases trapping this reflected energy. Solar panels are designed to absorb nearly all the energy that falls upon them from the sun. Our new secretary of energy has recommended paint the roofs of all our homes white so as to increase reflection of solar energy back into space.

When it comes to solar panels, the most immutable law of all concerning man's actions of all comes into play - the law of unintended consequences.
