“…15b) prototype. This arises from an increase in PV cell temperature (Joy et al, 2016). Notably so, the decrease in open circuit voltage during the outdoor experiment is greater for panel 10, 11 and 12 which are located near the hot air trap and hence are likely to be subjected to a higher local ambient temperature.…”

This paper reports the development and application of a new practical photovoltaic (PV) cells based device to measure the solar radiation flux produced by non-imaging Compound Parabolic Concentrators (CPCs) on cylindrical absorbers. The flexible experimental device comprises 12 discrete miniature PV panels that measure solar radiation on the surface of a cylindrical absorber. The device has been used to evaluate the performance of an asymmetric CPC system and results validated with a computer-based Ray Tracing Model. The study attained significant agreement between outdoor results of the experimental device and results of the ray tracing simulation with a difference of <9 % in optical efficiencies. The non-imaging reflector illuminates a targeted section of the absorber of a horizontal east-west thermal diode Integrated Collector Storage Solar Water Heater. During outdoor testing, the experiments indicated a local concentration ratio reaching 1.4 suns on the targeted section of the absorber vessel surface for incidence angles −30°≤ ≤ 30°, confirming technical suitability of the asymmetric CPC for deployment in locations at equatorial latitudes.

The temperature of Photovoltaic (PV) module rises by absorbed incident solar radiation and causes subsequent drop off in electrical efficiency. To overcome this ill effect, an appropriate material must be used to absorb the heat and maintain the temperature of PV module. The purpose of present study is to review and understand various cooling techniques used to enhance cooling and electrical performance. The emphasis was placed on design and operating parameters like absorber configuration, flow pattern, flow rates, climatic conditions, radiation intensity, wind speed, thermal conductivity, glazing, concentration on the electrical and thermal characteristics. The reviewed papers include theoretical analysis, computer simulation, solar simulator and on-field experiments. The study states that the proper selection and utilization of cooling technology, design and process parameters are the key elements in the solar photovoltaic (PV) system to achieve optimum performance.

“…The proposed method is shown to be easily integrated with a building. Many other techniques are available in the literature related with the HPV/T design including absorbers, PV cells and cooling path (Ooshaksaraei et al, 2017;Liang et al, 2015;Joy et al, 2016;Gholampour et al, 2014). Reaching high efficient HPV/T collectors for the market is the key target (Haurant et al, 2014).…”

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.
