Thermodynamic cycles have been widely used in conversion of solar radiation energy into the electrical power. Use of solar collector systems in Stirling engine has been investigated in recent literatures. Most applications of solar collector systems in Stirling engines are in space power and terrestrial power plant systems in which entirely directed at the electrical power generation. Less attention has been accomplished in small scale terrestrial applications such as in domestic application. In recent studies it has been identified that the Stirling engine has good potential for meeting continuous power requirements in the 5 to 20 kW range for electrical power generation and water pumping requirements in third world countries. The dish-Stirling system, comprises of a parabolic dish collector (which is made up a dish concentrator and a thermal absorber) and a Stirling heat engine located at the focus of the dish, tracks the sun and focuses solar energy into a cavity absorber where solar energy is absorbed and transferred to the Stirling engine to heat its displacer hotend, thereby creating a solar powered Stirling heat engine.
