The high-performance CPC-Trough Collector has been developed for the utility scale generation of low temperature solar hot water and steam for low temperature process heat applications including solar air conditioning. With an optical concentration of 4.5:1, operating temperatures over 130°C may be reached. This novel design has included a FEM validation and is compatible with the standard reflectors and evacuated tubes in the market. The peak efficiencies of 35% with unshielded and more than 45% with evacuated tube receivers were obtained. This CPC collector requires intermittent tracking i.e. tilt adjustment is only once in a week for more than 8 hours collection in summer and 6-7 hours in winter seasons.
