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.
In solar thermal energy, all concentrating solar power (CSP) technologies use solar thermal energy from sunlight to make power. A solar field of mirrors concentrates the sun's energy onto a receiver that traps the heat and stores it in thermal energy storage till needed to create steam to drive a turbine to produce electrical 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.
The dish concentrator must be oriented towards the sun. Usually, losses in this technology are associated with the imperfections of dish alignment and non-ideality of reflection. The engine that converts the concentrated solar energy into electricity is placed at the focal point.
In solar thermal systems, concentrators are used to extract the energy from solar irradiation and convert it into useful form. Among different types of solar concentrators, the parabolic dish solar concentrator is preferred as it has high efficiency, high power density, low maintenance, and potential for long durability.
