While I’m waiting until I can afford some photovoltaic panels, I wonder what is happening to all the photons pummeling my roof now?
If the (light) energy from one square cm of solar radiation is converted into electrical energy and then converted to heat by Aunt Matilda's blow-dryer, what would have otherwise happened to the energy from those same photons - if Matilda had not hired Green Inc. to install all those shiny, black rectangles on her roof?
Would they have been absorbed by the roof? If so, presumably they would not make Matilda's house glow in the dark. So, they would somehow be transformed into heat, or some other form of energy?
Would they have bounced back into space, taking their energy with them?
