The receiver can be an evacuated tube collector with a secondary parabolic shape concentrator, while designs with trapezoidal cavities are also usual. Solar dish concentrator (SDC) Solar dish concentrators are focus-point technologies which present high concentration ratios (~ 100).
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.
They found that the combination case is the best case with 0.82% thermal efficiency enhancement when the use of fins leads to 0.62% and the use of nanofluids to 0.26%. Solar dish concentrators are concentrating collectors under developments, and different ideas are applied to them.

Solar dish concentrators are concentrating collectors under developments, and different ideas are applied to them. Commercially, there are solutions with dish concentrators with Stirling engines . However, the use of the SDC for useful heat production is not established. Below, the most interesting recent ideas on this domain are presented.
Solar Parabolic Dish (SPD). It is a parabolic point-focus concentrator. A dish that reflects solar radiation into a receiver’s focal point. The capacity ranges from 0.01 to 0.5 MW, and they are generally accompanied by a Stirling cycle with an electrical efficiency between 25% and 30% [6, 12]
