This review discuss about parabolic dish solar collector (PDSC). PDSC uses concentrating solar irradiation at a focal point technology, where the output of PDSC is coupled with a number of useful applications. PDSC has higher concentration ratios (1000–3000) when comparing with other concentrating technologies (A. Kalogirou. 2018).
Why is the concentration ratio an important metric of a solar concentrator? Simply put, the concentration ratio is an important ingredient in optimizing the efficiency of a concentrated solar power plant. By increasing the concentration, more light is focused onto the same collecting area, which causes more energy to be deposited in the same ...
