Why is concentration ratio important in a concentrated solar power plant?
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 amount of time.
