The conversion efficiency of cpv solar system can reach 26.5%.
CPV solar system has primary reflector and secondary reflector to make solar focus, and has light tunnel to achieve high concentrating ratio. The mirror is made of metal aluminum or casting forming glass and coated with HR, so that it can maintain stable even under the environment with high temperature and humidity and strong ultraviolet radiation. Now SolFocus and JX Crystals has adopted this structure in their system.
