Optimal Design of Compound Parabolic Concentrator Solar Collector
The multi-objective optimum design of stationary compound parabolic concentrator (CPC) solar collectors is considered. The clear day solar beam radiation and diffuse radiation at the location of the solar collector are estimated. Three objectives are considered in the optimization problem formulation: maximization of the annual average incident solar energy,

Numerical analysis of spectrally selective photovoltaic-thermal
Solar district heating (SDH) systems have been extensively studied to phase out fossil fuels [8], [9]. Compared to conventional solar thermal collectors, photovoltaic-thermal (PVT) technology can capture more useful energy in a limited area due to its ability to produce both heat and electricity [10]. In PVT systems, heat from the PV modules is
