The individual photovoltaic (PV) cells on a solar panel contain a semi-conductor material that absorbs sunlight, generating direct current (DC) energy. Inverter technology then converts this to alternating current (AC) energy, making it useable for your home. Once your solar energy system has been installed and is up and running, it’s this solar energy you use every time you flip a light-switch, turn on your TV, or charge your phone. You’ll still be connected to the grid, but you’ll only need to use grid power if you run out of solar power.
