Whats the difference between PV and other solar technologies?
There are four main types of solar energy technologies: • Photovoltaic (PV) systems, which convert sunlight directly to electricity by means of PV cells made of semiconductor materials. • Concentrating solar power (CSP) systems, which concentrate the sun’s energy using reflective devices such as troughs or mirror panels to produce heat that is then used to generate electricity. • Solar water heating systems, which contain a solar collector that faces the sun and either heats water directly or heats a working fluid that, in turn, is used to heat water. • Transpired solar collectors, or solar walls, which use solar energy to preheat ventilation air for a building.
