Q. How does solar power work?
The two most common types of solar energy technology are photovoltaic (PV) cells and solar thermal collectors. PV cells contain a semiconductor material (typically silicon-based) which converts sunlight into direct-current (DC) electricity. An inverter converts this DC power to 230-volt 50 Hz AC power, which can then be connected to a home or building power supply. Solar thermal collectors absorb the sun thermal energy and use it to heat water or other fluids, which can be used for hot water applications or circulated through a home or building for space heating.
