It allows the direct conversion of solar energy into electrical energy thanks to a solid electronic technology of high reliability and a lifetime exceeding 25 years.
Thanks to the possibility of interconnection, photovoltaic solar panels offer very high power modularity from a few fractions of W for calculators to KW for decentralized systems (electrification, water pumping, radio relay, etc.,) and even dozens of MW for photovoltaic plants.
The electricity produced by the photovoltaic panels is in the form of direct current and can be stored in batteries or be converted into alternating current by an inverter before injecting it, for example, into the national electricity grid.
It allows the direct conversion of solar energy into thermal energy by the effect of concentration of solar rays at a precise point of the system, thus reaching high temperatures. This makes it possible to create high-pressure water vapors rotating turbines that drive electric generators.
There are several processes:
- Solar power tower: a multitude of mirrors reflect the sun’s rays at a single point on a tower.
- Parabolic through: mirrors shaped like parabolic cylinders concentrate the sun’s rays into a vacuum tube in which a heat transfer fluid circulates.
- Dish Stirling: it is a stand-alone parabolic reflector that concentrates light onto a receiver positioned at the reflector’s focal point
