“…The results obtained by the researchers showed that the efficiency of the PV module can be enhanced by 47% using a cooling system. Shmroukh [17] demonstrated through their study that the efficiency of a PV module could increase to an average of 8.5% using a closed-loop free-convection system for the cooling; however, it can reach 10.5% using a closed-loop forced convection system. The system without cooling recorded a daily average efficiency of only 6.2% while the open-loop system recorded 11.3%.…”

A photovoltaic (PV) module’s electrical efficiency depends on the operating temperature of the cell. Electrical efficiency reduces with increasing PV module temperature which is one of the drawbacks of this technology. This is due to the negative temperature coefficient of a PV module which decreases its voltage significantly while the current increases slightly. This study combines both active and passive cooling mechanisms to improve the electrical output of a PV module. A heat sink made up of aluminum fins and an ultrasonic humidifier were used to cool the panel. The ultrasonic humidifier was used to generate a humid environment at the rear side of the PV module. The cooling process in the study was able to reduce the temperature of the panel averagely by 14.61 ℃. This reduction led to a 6.8% improvement in the electrical efficiency of the module. The average power of 12.23 W was recorded for the cooled panel against 10.87 W for the referenced module. In terms of water consumption, a total of 1.5 L was approximately consumed during the whole experimental process due to evaporation. In effect, the proposed cooling approach was demonstrated as effective.

The paucity of freshwater is very dangerous in the coming years. Many coastal countries suffer from a scarcity of freshwater. Solar desalination is the cheapest way to produce freshwater from any type of non-drinkable water (brackish water and seawater). In this work, single-slope single-basin solar still for seawater desalination was examined under Upper Egyptian weather conditions of Qena City (latitude 26.16°, longitude 32.71°). The main goal of the work is to compare the performance of conventional solar still, solar still supported with PCM, and solar still supported with local clay material to augment the solar still yield during both daytime and nighttime periods of operation. The results demonstrated that the total production of desalinated water from the simple conventional solar still, the solar still with PCM, and the solar still with local clay reached about 3885, 4704, and 5388.6 ml/m2, respectively. Moreover, compared to the conventional solar still, the yield was increased by about 21% when using the PCM, and about 38.7% when using the local clay material. Furthermore, it can be observed that the daytime productivity in the case of solar still supported with local clay was higher than that for the solar still supported with PCM, while the nighttime productivity was higher in the case of solar still supported with PCM compared with solar still supported with local clay. Moreover, the average daily efficiency of conventional solar still, solar still with PCM, and solar still with local clay reached about 34, 41.2, and 47%, respectively. Therefore, it is recommended to use the solar still with local clay for seawater desalination in such arid and hot climate of Qena City.

Photovoltaic (PV) panels generate some of their energy as waste heat while converting solar radiation into electricity. This heat in photovoltaic panels adversely affects the output parameters of the panels. For this reason, there are many studies on cooling of PV panels in the literature. In this experimental study, waste heat was removed by placing DC fans with different numbers and different consumption power on 80 W monocrystalline panels. According to the results obtained from the experiments, while the net power of the reference panel was 62.42W, the net power of the E4 system (with 4 fans and the consumption power of the fans was 10W) was measured as 64.1W. The highest exergy efficiency and sustainability index values among all systems were also obtained from the E4 system.
