How Solar Energy Works in Your Home

The Basics of Solar Energy

Sunlight strikes the photovoltaic array, generating a DC voltage. An inverter converts this to standard AC voltage. This voltage is fed into the building's circuit panel. Energy from the inverter will then be used to power your home. Any surplus of PV power is fed back to the utility, running your utility meter backward and giving you a credit!
