The atmospheric water harvester photovoltaic cooling system provides an average cooling power of 295 W m –2 and lowers the temperature of a photovoltaic panel by at least 10 °C under 1.0 kW m –2 solar irradiation in laboratory conditions.
The cooling component in the design is an atmospheric water harvester (AWH). The AWH collects atmospheric water vapour by a sorption-based approach in the evening and at night, and then the sorbed water is vaporized and released during the day by using the waste heat from the PV panel as energy source 27, 28, 29, 30.
It can be implemented as either passive or active cooling, providing adaptable solutions to meet specific requirements. 3.1.1. Water immersed PV Immersed photovoltaic systems offer an effective way to enhance solar power generation.
This review paper provides a thorough analysis of cooling techniques for photovoltaic panels. It encompasses both passive and active cooling methods, including water and air cooling, phase-change materials, and various diverse approaches.
Compared to the uncooled panel, the power output was increased by 7 % for fin cooling and 10.2 % for water cooling. Also, the performance ratio was increased from 77 % to 81 % and 84 % for these two methods, respectively. Harahap et al. investigated the effect of employing water cooling in a PV panel to improve its temperature performance.
The excellent heat absorption properties of water make water-cooling a specialized technique for improving the performance of photovoltaic systems. By efficiently dissipating excess heat, this approach contributes to improved temperature control and overall PV system efficiency.
