In a typical solar power generation system, the sunlight strikes the solar panels, generating DC electricity in the photovoltaic (PV) cells. The DC voltage travels through cables to the inverter and the inverter converts the DC electricity into AC electricity. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations. . The sun emits solar radiation in the form of light. Sunlight is composed of photons, or particles of solar energy. . Solar energy can be harnessed two primary ways: photovoltaics (PVs) are semiconductors that generate electricity directly from sunlight, while solar thermal technologies use sunlight to heat water for domestic uses, to warm buildings, or heat fluids to drive electricity-generating turbines.
