Solar works when sunlight hits photovoltaic modules and “excites” electrons. These electrons are captured in wires and directed towards an inverter. The inverter converts the DC power that is created into usable AC electricity. The inverter is typically connected to your house electrical loads through a breaker that is added to your existing electrical panel. When the sun is shinning your solar will power the electric loads in your house. When you produce more electricity than you consume the excess is sent though your electric meter to “The Grid”. Your local utility keeps track of all the electricity you send back through your meter and credits you for this production.
