Alternating current (AC) is used by lights, electrical appliances, and machines in the U. S. The voltage of this electricity is constantly alternating. PV systems, however, produce direct current (DC), which has a constant voltage. This electricity has to be converted to AC by electronic equipment called an inverter in order for it to be used by standard electrical devices.
