Fresnel lenses are used as solar concentrators since they offer high optical efficiency along with minimal weight and low cost [78].Though Fresnel lens concentrators have been used in solar energy concentration systems since 1960s, due to the above said potential development of Fresnel lenses in commercial solar energy concentration is still ongoing.

The design fabrication and testing of a solar parabolic dish concentrator for application in remote areas is presented in this project. The solar concentrator was design and fabricated with low cost available material and skills that can be operate and easily repaired by the users and can be track manually to follow the movement of the sun.

concentrator is that it is very compact, since only truncated version of the concentrator needs to be used. Because of this factor, it is mainly used as a secondary concentrator. An example of application of this concentrator has been developed by Sol Focus, with the intention of reducing the cost of solar electricity.

The optical concentrators are usually classified as reflective and refractive types. Reflective and refractive concentrators use mirrors and lenses to reflect and refract sunlight, respectively (Freier et al., 2018).Another way of classifying optical concentrators is based on their respective geometric concentrations, which include high concentration, medium concentration, …
