The solar thermal system works simply by pumping cold water into the pipes within your solar thermal panels, which are fitted on your roof. The sun then heats up the cold water within the pipes. The now hot water is pumped into your hot water cylinder where it is stored until needed.
1 Photovoltaic (PV) systems, which convert sunlight directly to electricity by means of PV cells made of semiconductor materials. 2  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.t is the basic physical process in which a solar electric or photovoltaic (PV) cell converts sunlight to electricity. Sunlight is made up of photons, or particles of solar energy. Photons contain various amounts of energy, corresponding to the different wavelengths of the solar spectrum.
