Compound parabolic collectors (CPCs) are non-imaging concentrators. They have the capability of reflecting to the absorber all of the incident radiation within wide limits. Their potential as collectors of solar energy was pointed out by Winston (1974).The necessity of moving the concentrator to accommodate the changing solar orientation can be reduced by using a
Customer ServiceThe PTC reflectors need to face the sun continuously hence the PTC collectors have Sun tracking mechanism. The Sun travels at a definite pace from east to west every day. The algorithm based controller governs the tilting movement of the PTC collectors at regular interval to maintain the acceptance angle within permissible limit
