Cleanergy Solar Stirling Unit

Stirling -Dish Systems are small power generation sets which generate electricity by using direct solar radiation. The capacity of a single unit is 10 kW electric power. The modularity of the Cleanergy solar stirling units qualify the Dish-Stirling system for very flexible applications. They are ideal for standalone or other decentralized applications as well as clusters with a capacity of up to several 100 megawatts.

The parabolic concentrator reflects the incoming solar radiation onto a cavity receiver which is located at the concentrator’s focal point. The solar radiation is absorbed by the heat exchanger and thus heats the working gas of the Stirling engine to temperatures of about 650°C. This heat is converted into mechanical energy by the Stirling engine. An electrical generator, directly connected to the crankshaft of the engine, converts the mechanical energy into electricity (AC). To constantly keep the reflected radiation at the focal point during the day, a sun-tracking system rotates the solar concentrator continuously around two axes to follow the daily path of the sun. The Stirling cycle is the most efficient thermodynamic cycle to transform heat into mechanical or electrical energy.
