How does solar photovoltaic work?


-Photons from the sun hit the solar panels, which are made from a special kind of silicon

-The photons excite the electrons in the silicon and get them to move creating DC electricity (similar to electricity in a battery)

-The DC electricity tracks to a special appliance called an inverter that converts the DC to AC (electricity in your home or business)

-The AC electricity feeds your electricity panel like your power company does to lower your bills

-The electricity goes to power your home. If you create more than you need, you sell it to the power company so you can buy it back at night. Optional batteries can allow system to stand alone or "off grid".
