How is solar electricity produced?
Photons from the sun hits electrons in silicon atoms within the solar cell. If the photons have sufficient energy, that energy is absorbed by the electrons in the outer orbit, which then use the energy to break free of their atoms and travel through a circuit, causing the flow of electricity. I have a science project due. Where can I get an inexpensive panel? Small panels and appliances are readily available from local electronics stores, such as Radio Shack. Help! I need all the free science information you can give me. There is a terrific amount of scientific information available. If you ask a specific question, we will try to answer you.
