A solar dish, or parabolic dish, is a device that uses mirrors to focus light coming directly from the sun to a point, for collection and use for power generation, thermal or thermochemical processes.The dish faces the sun and must be able to move to follow its path in the sky throughout the day. A solar dish has several key subcomponents, described here as
Dish Stirling systems have demonstrated the highest efficiency of any solar power generation system by converting nearly 30% of direct normal incident (DNI) solar radiation into
Solar generation is highly variable. Power generation with solar energy is limited to daytime given that the sun does not shine at night. Consequently, capacity factors of solar power plants (without storage) are lower compared to other technologies and typically range between 10% and 20% in most regions, reaching up to 25% at the best spots in

According to the solar dish design analysis, it is noted that the optimal system performance is highly dependent on the dish diameter, rim angle, receiver diameter, and geometric concentration ratio. As a significant portion of losses occurs at the Stirling engine, the SE’s efficiency is a critical factor that shows the PSDS system’s effectiveness.
It was found that the dish diameter directly affects the peak temperature of SE. Predicted the radiative thermal performance of a parabolic solar dish and a thermal cavity receiver system employing the MCRT method combined with the optical properties of the system.
