All concentrating solar thermal power (STP) basic elements: Concentrator Receiver Transport-storage (a portion of the thermal energy is stored for later use) Steam generator (Heat exchanger) Condenser Steam turbine Alternator 


 Explanation (Operation): The concentrator captures and reflect solar radiation towards collector (absorber) The receiver absorbs the concentrated sunlight rays and gets heated. The secondary fuel (coolant or working fluid) is passed through collector. Transferring its heat energy to a working fluid. This coolant gets heated to a very high temperature. This hot coolant is stored in transport-storage system (a portion of the thermal energy is stored for later use).Thus solar energy can be used even when sun rays are not available Then hot coolant is passed through heat exchanger (steam generator) where steam at high temperature and high pressure is generated. This secondary fuel (coolant or working fluid)is re-circulated again and again. This steam at high temperature and high pressure is used to run the steam turbine. Steam turbine is coupled with alternator which converts mechanical power to electrical energy Exhaust steam is condensate in condenser
