Concentrating Systems - Solar Concentrator

Solar concentrator is a primary solar component of Dish Stirling technology. Prefabricated steel zinc coated parabolic concentrator delivers the sun’s fuel into the focal point where PCU with Stirling engine’s receiver is placed. The concentrator’s area is 57m2. The parabolic concentrator reflects the incoming solar radiation (DNI) through glass mirrors onto a cavity receiver which is located at the concentrator’s focal point. Special proved silver coating glass mirrors reflect more than 94% of the sunlight and mirrors can be easy cleaned. The reflective solar radiation is absorbed by the heat exchanger receiver and thus heats the engine’s working gas Helium. In order to keep constantly the reflected radiation into the focal point during the day, double sun-tracking systems aim the solar concentrator continuously in two axes direct into the sun.
