“…The PV temperature has been recorded to have come down by an effective 25°C. Browne et al (2015Browne et al ( , 2016 have performed experiments with a differently synthesised compound constituting various materials that are chemically inert to each other. Different fatty acids are used to form the desired PCM that have caused temperature drop of 5.5°C.…”

Temperature management in photovoltaic (PV) is critical for the power output. Phase Change Material (PCM) usage enables one to remove heat from the system and achieve enhanced electrical output. This study aims at finding the period of PV electrical enhancement, the increase in power and increase in electrical efficiency achieved using PCM under different working circumstances. Results suggest that as the angle of approach of wind changes from 75° to 0°, the electrical enhancement period elevates from 7.0 h to 8.6 h for 5 cm deep PCM box.

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.

“…When the difference in the temperature at the inlet and outlet of the module is approximately 20 • C, the electrical efficiency can be increased by 9% using a suitable PCM. Browne [13] experimentally compared and analyzed the thermal collecting capacity of a PV/T-PCM and PV/T systems. The temperature of water at the outlet of the PV/T-PCM panel was found to be higher than that of the PV/T panel by 6 • C. Qiu [14] theoretically studied the performance of a PV/T system comprising a phase change microcapsule suspension as the working fluid.…”

This study aimed to investigate the performance of a novel encapsulated phase change material (PCM) photovoltaic/thermal (PV/T) system. A PCM, which has a high latent heat capacity, can absorb energy from a PV cell and reduce the operating temperature, improving both the electrical and thermal efficiencies of the panel. In this study, a computer model based on a PCM PV/T panel is developed, and its accuracy is verified using experimental data. The effect of the phase change temperature on the performance of the panel was analyzed by numerical simulation. When the phase change temperature was 30.1 °C, the system exhibited a maximum electrical efficiency of 8.2% and a thermal efficiency of 71.8%. When the phase change temperature was 20.24 °C, the system had a maximum exergy efficiency of 33.7%. In general, the temperature of the PCM integrated into the PV/T system should not be too high.
