We present the design of an original secondary cavity for use in Small-Scale Fresnel Reflectors photovoltaic applications. The is similar to classical V-trough, but primary reflector system configured so that there are two focal points on aperture. rays coming from each side reach opposite cavity, producing a non-symmetrical distribution irradiance. This modifies acceptance half-angle and allow...

This work proposes a hybrid compound parabolic concentrator and trough (CPC/PTC) system for photovoltaic/thermal (CPV/T) photovoltaic/thermal-thermoelectric generator (CPVT-TEG) applications. The geometrical design optical analysis of the novel CPC/PTC are discussed in present study. Ray-tracing models were used to identify different variables that influence efficiency both CPC PTC. concentrati...

Application of solar collectors for hot water supply, space heating, and cooling plays a significant role in reducing building energy consumption. For conventional solar collectors, solar radiation is absorbed by spectral selective coating on the collectors' tube/plate wall. The poor durability of the coating can lead to an increased manufacturing cost and unreliability for a solar collector op...

An evaluation was carried out to investigate the feasibility of utilizing a molten salt as the heat transfer fluid (HTF) and for thermal storage in a parabolic trough solar field to improve system performance and to reduce the levelized electricity cost. The operating SEGS1 plants currently use a high temperature synthetic oil consisting of a eutectic mixture of biphenyl/diphenyl oxide. The sco...
