Solar dish/engine systems convert the ener-gy from the sun into electricity at a very highefficiency. Using a mirror array formed intothe shape of a dish, the solar dish focuses thesun's rays onto a receiver. The receiver trans-mits the energy to an engine that generateselectric power.
In their experiments, weather data, receiver temperature, cooling fluid flow rate and temperatures, and power production have been measured. It was found that the solar dish generates heat about 5440 kWh in 1326 h. Besides, the average temperature of the water was over 60 °C in the summertime, whereas, it dropped below 40 °C in wintertime.
It was indicated that the thermal efficiency was 25%, corresponding to a receiver temperature of 1596 K, for dish configuration system of 10.5 m diameter at a solar intensity of 1000 W/m 2. ( Beltrán-Chacon et al., 2015) established a theoretical model to assess the impact of operational and geometrical parameters on the SDSS thermal performance.
The annual amount of generated steam was found to be varied between 583 and 1072 kg per m 2 of the area of the dish, which gave the advantage for the SDS- cooking system over the conventional diesel-based institutional cooking system.
