The key drawbacks of solar thermal involve the upfront cost of installing the technology and the fact it is intermittent between day and night time. Whether you are an advocate of solar technologies or not, it is clear to see that the advantages of solar thermal far outweigh the disadvantages.
The review includes the opt-geometrical and thermal analyses, and applications of solar dish Stirling systems (SDSS). Analytical and ray-tracing approaches in the receiver cavity of SDSS for optical improvement are studied. The potential contribution of simulation and optimization tools in respect of the improvement of the SDSS is identified.
