On Grid Solar Power System: The arrangement of solar modules harvests the sunlight on them and convert them into electricity. The current generated here is Direct Current (DC). The solar inverter then converts the DC to Alternating Current (AC), thus making it power the electrical items. This electricity is then routed to the utility grid where it is supplied for day to day use. An important feature is the net meter. It is a device that records the energy exported to utility grid and imported from utility grid. At the end of each month, the outstanding is recorded and the consumer is provided with a bill.
