“…Later Nilsson et al (2006) reported the performance of electrical and thermal characteristics of PVT-CPC systems for different latitudes. Bahaidarah et al (2014) analyzed the comparative study between the flat PV string system and the PV-CPC system. They found that the performance (power output) of PV-CPC system is much better than the flat PV.…”

The uncertain analysis of fixed solar compound parabolic concentrator (CPC) collector system is investigated for use in combination with solar PV cells. Within solar CPC PV collector systems, any radiation within the collector acceptance angle enters through the aperture and finds its way to the absorber surface by multiple internal reflections. It is essential that the design of any solar collector aims to maximize PV performance since this will elicit a higher collection of solar radiation. In order to analyze uncertainty of the solar CPC collector system in the optimization problem formulation, three objectives are outlined. Seasonal demands are considered for maximizing two of these objectives, the annual average incident solar energy and the lowest month incident solar energy during winter; the lowest cost of the CPC collector system is approached as a third objective. This study investigates uncertain analysis of a solar CPC PV collector system using fuzzy set theory. The fuzzy analysis methodology is suitable for ambiguous problems to predict variations. Uncertain parameters are treated as random variables or uncertain inputs to predict performance. The fuzzy membership functions are used for modeling uncertain or imprecise design parameters of a solar PV collector system. Triangular membership functions are used to represent the uncertain parameters as fuzzy quantities. A fuzzy set analysis methodology is used for analyzing the three objective constrained optimization problems.

“…Different cooling techniques have been investigated to extract the heat generated by concentration. Cooling methods can be divided according to the fluid used into two: air cooling systems that use air to extract heat from the PV by using a heatsink attached to it or by cooling duct fitted underneath the CPV and water or other coolants flowing in a channel underneath the PV . Air cooling techniques were investigated by many researchers either with flat plate PV panel or LCPV system to reduce PV temperature and increase the power output.…”

Summary Improving photovoltaic (PV) system power output is the main target of research in this field. Using concentrators with PV systems should increase the power output and consequently reduce the power production costs. However, using concentrators with PV (CPV) system has a drawback of a higher PV system temperature, which affects the voltage produced by the system leading to lower overall system power output. This paper experimentally investigates the performance of a polycrystalline silicon PV cell with a low‐concentration ratio square aperture concentrator. A 50 × 50 mm cell was tested without concentration and with a range of geometric concentration ratios (GCRs) of 4, 6, 8, and 10. Various cooling methods were studied, including no cooling, passive cooling by using finned heatsink, and active cooling by using finned heatsink and a fan, and the CPV performance was presented in conversion efficiency, the electrical power gain, and the reduction in PV material at various testing conditions. Significant improvement was obtained by using square aperture concentrator at different GCRs with highest power gain of 362.85%, PV cell material reduction of 78.39%, and efficiency increase by 72% at GCR 10 and active cooling. The results do not consider the power needed to extract the heat generated by the concentration and reduce the cell temperature by using air cooling. But the extracted heat enhances the CPV system output if it is harnessed in domestic applications such as water heating applications. These results highlight the potential of the developed CPV system.
