Photovoltaic (PV) Electricity can be used to run a wide-range of equipments and systems with variable power requirements. PHOTOVOLTAIC S TAND-ALONE S YSTEM This poster is prepared by the researchers at the GERMI Research, Innovation and Incubation Center (GRIIC) as a knowledge dissipation initiative. December 2009. Battery Bank PV Panel Charge Controller Stores the the generated PV electricity. 1) Ensures maximum extraction of power from PV panel. 2) Controls charging and discharging of Battery. Instantaneously converts Sunlight into DC Electricity. Converts DC electricity into commonly used AC form. DC load AC Load Inverter Stand-Alone Photovoltaic Systems are an attractive option for remote and clean power applications.
