A Comprehensive Review on Solar Parabolic Trough Collector

Solar energy is one among the freely available clean forms of renewable energy. Many technologies have been developed in India for extracting energy from assorted renewable energies, but the maximum extraction of thermal energy from solar energy is the most promising challenge. This paper focuses on the performance and efficiency of solar parabolic trough collector. In this paper, the design stages of a solar parabolic trough collector are presented. The sunlight collected is split by a cold mirror into visible light and inferred rays. The visible light and IR are used for day lighting and heating generation respectively. The receiver absorbs the incoming radiations and transforms them into thermal energy. Improving the performance of solar collectors has been recently a subject of intense research because of its advantages such as a decrease in the size and cost of systems and an increase in the thermal performance.
