Abstract: The solar power plant contains the radiation concentrator fitted with a drive, the system of Sun tracking with a control unit, and a fixedly attached radiation detector, and the drive is made with a possibility of ensuring a straight-line reciprocating movement of the concentrator, and the concentrator is mirror-based with a cylindrical surface having a guide whose current radius value features a deviation from the average value corresponding to the circumradius of the circular cylinder guide by no more than ±10%, and the radiation detector—photoelectric converter, is located in the focal plane.
