The solar parabolic dish systems convert the heat from the solar radiation of the sun, which represents as thermal energy to concentrating solar thermal power.
The dish is made of a flat support structure with mirrors arranged in a Fresnel-like array and tracks the sun using a hydraulic drive system. The first application was generating high-temperature air as heat transfer fluid (HTF), using a pressurized volumetric receiver.
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.
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 the reflector, support structure, tracking system, foundations, receiver, and receiver support (Fig. 1). Schematic diagram of a solar dish (tracking system not shown)
The solar dish systems can reach to higher temperature ranges from higher concentration of thermal power. The higher efficiency achieved from the higher temperature that lead to better electricity generation and conversion, and that leads to high power densities and lower cost with respect to other CSP technologies.
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.
