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 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.

A thermal heat-pipe receiver was chosen to isothermally convert the concentrated solar energy from the parabolic dish to the AMTET. Their findings unveiled that the solar dish –AMTEC system produced a net power of 18.54 kW with an efficiency of 20.6%. Fig. 25. The solar dish/AMTEC power system ( Wu et al., 2010 ). 7.2.

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.

The proposed system was utilized in three related purposes: producing freshwater, supplying power, and refrigeration. The results indicated that a 21,030 kW of thermal power could be produced by dish collectors which consequently converted into 4632 kW electrical energy in a steam power plant.
