This paper presents a novel design of V-trough Solar Concentrator (VSC) for low concentrator photovoltaic (CPV) applications. The conventional VSC design comprises of two flat reflectors slanted by an angle and attached to a PV module. The maximum reported concentration ratio (CR) and optical efficiency (OE) of this concentrator are 2x and 89.91%, respectively. This paper demonstrates the process of improving the VSC. The geometrical and optical performance of the conventional VSC were optimized by the theoretical image technique. The experimental CR and OE are increased by 43.50% and 4.32%, respectively. Then, a crossed V-trough design "Pyramid" is suggested to increase the concentrated radiation. Pyramid concentrator boosted the CR, but the OE is dropped. Eventually, a new VSC geometry is proposed and resulted in CR of 4.70x and OE of 91.83%. The new design demonstrates the possibility of obtaining the same CR using a smaller reflector area than conventional and pyramid V-trough configurations, leading to a reduction in production cost. The results show the potential to further improve this type of solar concentrator for photovoltaic applications.

Hybrid photovoltaic/ thermal systems are very promising clean energy harvesting devices where they can be used either standalone system or can be incorporated with other systems. In this study, historical developments leading to current Hybrid Photovoltaic/Thermal (HPV/T) systems as it is used today and global findings to enhance the performance of HPV/T system through state-of-the-art analyses are presented in a thematic way. The findings from initial studies on the HPV/T systems is revealed in an historical way and rest of sections are formed based on selected criteria. The paper covers basic and advanced type collectors, working fluids, analyzing methods to assess performance, thermodynamic approaches, optimization of design parameters and mass flow rates, techniques to enhance performance and comparative studies. Especially, various parametric studies to optimize performance of the HPV/T with respect to selected parameters including different types of absorbers, packing factor, cooling schemes, working fluid types, modifications at different sections of the system are comprehensively investigated. Based on the conclusions, the variation in electrical and thermal efficiencies are mainly in the scope of this study. It is observed from the literature that solar HPV/T system has a great potential to be one of the up and coming clean energy technology.

“…In the literature, many hybrid solar PV/T systems had been designed with optical filters. Some studies had shown that clean fluids like water and organic liquids could be used with the solar PV systems as optical filters [15][16][17]. A. Qahtan et al [18] had examined the possibility of using the Sustainable Glazed Water Film SGWF as spectrum filter for buildings in the Torrid Zone.…”

“…Initially, type of the employed PV cells affects the PV module electrical performance. Depending upon the kind of these cells and climatic circumstances, a standard PV module transforms (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) % of the falling solar radiation into electricity. The residue of solar radiation is transferred into heat, which elevates the module temperature and reduces its efficiency [1].…”

The fall angle of sun rays on the surface of a photovoltaic PV panel and its temperature is negatively affecting the panel electrical energy produced and efficiency. The fall angle problem was commonly solved by using a dual-axis solar tracker that continually maintains the panel orthogonally positioning to the sun rays all day long. This leads to maximum absorption for solar radiation necessary to produce maximum amount of energy and maintain high level of electrical efficiency. To solve the PV panel temperature problem, a Water-Flow Double Glazing WFDG technique has been introduced as a new cooling tool to reduce the panel temperature. In this paper, an integration design of the water glazing system with a dual-axis tracker has been accomplished and experimentally tested in order to enhance the PV panel efficiency, especially at hot climates. The proposed glazing system can simultaneously perform two functions, firstly, working as a cooling tool for reducing the stored heat in the PV panel during its work and secondly as an optical filter for sun light spectrum. Optimum design factors with their levels for the glazing system were calculated according to Taguchi method. Test experiments were carried out in Baghdad city on the 20th and 21st July 2016 on the tracker with and without using the WFDG system. The obtained results show that, the PV panel temperature with using the WFDG system was significantly dropped by 44% and its efficiency increased maximally by 36.6% at solar irradiance of 1213W/m2 as compared with conventional one.
