Method and System for Optimizing Secondary Reflectors in Solar Collectors

Concentrating solar power collectors generate electricity by harnessing the thermal energy of sunlight, and Transparency Market Research projects the global concentrated solar power market will grow at a CAGR of 20.3% to $8.67 Billion in 2020. Concentrating solar collectors use an array of mirrors or lenses that track the sun to reflect sunlight onto an absorbing medium which drives a turbine to generate power, or heat can be stored in molten salts to generate power at a time when demand is greater. The compound effect of reflection errors caused by imperfect mirror specularity, mirror slope error, mirror tracking error, and absorber position error often necessitates the use of a secondary reflector closer to the absorber to refocus reflected sunlight on the target. To generate the greatest amount of power possible it is crucial that the secondary reflector is optimized for the design of the collector system.
