This graphic illustrates a parabolic dish of mirrors directs and concentrates sunlight onto a central engine that produces electricity. The solar concentrator, or dish, gathers the solar energy coming directly from the sun.
Using mirrored dishes, dish-type concentrated solar power systems efficiently concentrate sunlight onto a receiver to harness solar energy for electricity generation. These
The performance of the solar Stirling power generation system is predicated by the test results of the solar collector and the Stirling engine generator in low output range.

Solar dish/Stirling system A typical SDSS system is composed of a parabolic concentrator connected to a power conversion unit (PCU) as shown in Fig. 2 (a) and (b). The latter consists of a Stirling engine, a spiral cavity receiver, and an alternator.
The review includes the opt-geometrical and thermal analyses, and applications of solar dish Stirling systems (SDSS). Analytical and ray-tracing approaches in the receiver cavity of SDSS for optical improvement are studied. The potential contribution of simulation and optimization tools in respect of the improvement of the SDSS is identified.
Designed a 20 kW PSDC hybrid solar/gas dish Stirling (HS/GDS) system. Within design conditions, the net efficiency of the system during day and night time was 27.58% and 33.94%, respectively. Constructed parabolic solar dish of polished stainless steel, this has offered the reduced cost concerning the preceding solar dish technologies.
The resulting beam of concentrated sunlight is reflected onto a thermal receiver that collects the solar heat. The dish is mounted on a structure that tracks the sun continuously throughout the day to reflect the highest percentage of sunlight possible onto the thermal receiver.
