9.1. Introduction Dish concentrating solar power (CSP) systems use paraboloidal mirrors which track the sun and focus solar energy into a receiver where it is absorbed and transferred to a heat engine/generator or else into a heat transfer fluid that is transported to a ground-based plant.
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.
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.
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.
The dish/engine system is a concentrating solar power (CSP) technology that produces smaller amounts of electricity than other CSP technologies—typically in the range of 3 to 25 kilowatts—but is beneficial for modular use. The two major parts of the system are the solar concentrator and the power conversion unit.
