Solar photovoltaic (PV) is a very simple system, first there are panels, which collects the sunlight and turn it into electricity. The DC signals are fed into an inverter, which converts the DC (direct current) into AC power (alternating current): which is what you use in your home. Various switch boxes are included for safety reasons, and the whole thing is connected via wires and conduits. This virtual application allows its user to learn how the switch works and to dissect its structure.
