In solar thermal power plants, the primary function of solar concentrators is generating the steam required to drive turbines that are connected to generators. Solar thermal power plants consist of two main units as follows [44]: 1. a solar field composed of concentrators that absorbs the sun''s rays and produces steam by the absorbed heat; 2.
