Concentrating solar power is a very useful tool that enables reaching high temperatures in solar energy conversion systems. Without concentration, the generation of electricity by conventional steam turbines using energy directly from the sun would not be cost effective. Optical concentration proves to be very advantageous since it reduces thermal losses and increases the useful energy gain.
