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 temperature of the water and ambience were recorded with the aid of temperature sensors (±0.2°C accuracy) and the average water temperature was determined by taking average at all the point of measurement. The solar irradiance was assessed using a high precision solar meter (accuracy of ±10 W/m 2 ) [30]. The following paragraphs examine and report the average values in even more detail.…”

The heat transfer performance of a flat plate solar water heating system was investigated experimentally in this paper (FPSWHS). The main objective of this investigation is to analyze the behaviour of FPSWHS with a 1.5 m2 receiver surface area in South Indian weather conditions and to calculate the heat energy created by the receiver for residential usages, which lessens electricity usage and assists the nation in conserving energy acquired from carbon fuels. Water was employed as the working medium in this investigation. The trials have been conducted in the first week of March 2021 at 13.0827° North, 80.2707° East. The findings confirmed that the solar thermal system's estimated average efficacy remained 44.3%, and the system's maximum output temperature of water was 67°C.

Solar photovoltaic (PV) energy is one of the most widely used renewable energy options around the world. However, its electrical efficiency drops with increasing PV module temperature, it is therefore necessary to find appropriate ways to improve the performance of the module under high temperature conditions. In this study we evaluated the impact of simultaneous dual surface cooling on the PV module's output performance experimentally. The PV module's rear surface was cooled using cotton wick mesh which absorbs water from a perforated pipe and use capillary action to transfer the water down the surface of the rear side of the module. The perforated pipe is strategically positioned at the upper part of the panel and as a result, water from the tank through the holes in the pipe also spread on the front surface of the panel. The experiment recorded a temperature drop of 23.55 °C. This resulted in about 30.3% improvement in the output power of the panel. The cooled PV module also recorded an average efficiency of 14.36% against 12.83% for the uncooled panel. This represent a difference of 1.53% which is 11.9% improvement in the electrical efficiency of the cooled panel. In effect, the proposed approach had a significant positive effect on the energy yield of the PV system.
