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.
solar panels directly into the grid can save you money. If you want to use solar power as backup when. the electricity goes out, you will need to connect batteries to your solar power system. Solar panels. convert the sunâs energy to electricity, but do not store electricity.n some. states, your utility account may be credited with the amount your solar panels feed into the grid. The installation of solar panels into the grid to power your home involves working with high-voltage electricity.
