Problems solved by technology

The inherent defect of tower-type solar thermal power generation is poor wind load resistance. The wind load of the heliostat is proportional to the area. The larger the area, the greater the wind load, so the heliostat shakes more seriously, which directly causes the surface of the solar receiver to be damaged. The energy flux density drops sharply, and the temperature of the heat transfer medium also fluctuates greatly
