Thecentral receptor system(solar towers) uses mirrors (heliostats), which follow the sun and reflect its light onto a fixed receiver at the top of a tower, where temperatures of over 1,000 °C can be reached. The main advantage of this alternative is that it allows the thermochemical storage of energy with the aim of generating electricity (despite the presence of solar radiation).
In fourth place are thedish systemswhich are shaped like a paraboloid and concentrate sunlight onto a receiver mounted at the focal point, with the receiver moving with the dish.
