SOLAR ARRAY – An interconnected system of PV modules that function as a single electricity-producing unit. The modules can be assembled both in series and parallel to generate a D/C voltage when photon rays from the sun hit the panels. Arrays usually send this D/C voltage into a solar inverter.
INVERTER – A device that converts direct current electricity from a (PV) array to usable alternating current either for stand-alone systems or to supply power to an electricity grid. Inverters typically back feed the A/C voltage through a circuit breaker in the main service panel onto the buss bar.
MAIN SERVICE PANEL – a main service panel provides a centralized site for redistributing power to secondary supply lines. Solar inverters feed power through breakers in this panel onto the buss bar that is used for everyday items such as appliances, lights, computers, and all household needs.
BI-DIRECTIONAL METER – A meter supplied by the local utility that is capable of reading and displaying the flow of electricity either being used by a home or building, or energy that is being fed back to the utility grid.
