However, the dish type solar thermal power generation system is widely used due to the high efficiency (Virk et al., 2015, Ho, 2016). Thus, it is very necessary to study the dish solar thermal power generation system (Ho and Iverson,

Based on the current solar thermal energy efficiency, an average CSP plant such as a tower solar power plant, dish Stirling, or parabolic trough plant requires the use of a land area of approximately 10 acres per megawatt (MW) of power generating capacity, which is more demanding than that for solar PV power generation (6–8 acres).
Only the power tower solar field technology is considered to be capable of reaching these temperatures and unit sizes Partially expanded steam has already given up some of its exergy to power generation, so using it to pre-heat feedwater destroys less exergy than allowing the highest temperature heat source to heat the feedwater from
The sun is the most important energy source available to us. Outside the Earth''s atmosphere, the average power of the solar radiation perpendicular to the main direction of the sun rays is of the order of 1.36 kW/m 2.This quantity, which is traditionally called the solar constant, is not a constant and varies inversely proportional to the square of the distance from

9.1. Introduction Dish concentrating solar power (CSP) systems use parabo.loidal mirrors that 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.
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.
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.
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.
A dish system consists of (a) a paraboloidal shaped concentrator, (b) tracking system, (c) solar heat exchanger (receiver), (d) an (optional) engine with a generator, and (e) a system control unit ( Fig. 9.1 ). The concentrator tracks the sun biaxially in such a way that the optical axis of the concentrator always points to the sun.
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.
