Touted as a promising alternative energy source for decades, solar panels crown rooftops and roadside signs, and help keep spacecraft powered. But how do solar panels work? Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise many, smaller units called photovoltaic cells. (Photovoltaic simply means they convert sunlight into electricity.) Many cells linked together make up a solar panel. Each photovoltaic cell is basically a sandwich made up of two slices of semi-conducting material, usually silicon â the same stuff used in microelectronics. To work, photovoltaic cells need to establish an electric field.
The purpose of a solar charge controller does not become clear until you gain an understanding of how they work alongside solar panels to move power through your home. First, understand how solar cells work.The brighter the sunlight, the more voltage solar cells generate.he purpose of a solar charge controller does not become clear until you gain an understanding of how they work alongside solar panels to move power through your home.
