Abstract

The present experimental research work aims to investigate how water spray cooling of the surface of solar panels affects the electrical performance, particularly the output voltage. A series of solar panels were tested at various cooling temperatures. Without cooling, the average output voltage of the panel was 85.8 V. When the panel surface temperature was maintained at 34℃ by water spray cooling, the average output voltage increased to 89.72 V, which is 4.57% higher than in the case without cooling. Similarly, for surface temperatures of 35℃, 36℃, and 37℃, also maintained by water spray cooling, the average output voltages were 89.35V, 88.04V, and 87.83V, respectively, meaning that the improvements were 4.14%, 2.61%, and 2.36%, respectively. The findings indicate that water spray cooling can significantly improve the output voltage from solar panels. We found the maximum value of the output voltage at a surface temperature of around 34℃, and a gradual degradation appeared at higher temperatures. This preliminary experimental study points out the potential of water spray cooling as an effective way to improve the electrical characteristics and overall efficiency of solar panels, concerning those operating at high ambient temperatures. Additional investigation is necessary to examine the extended resilience, water usage, and financial aspects of incorporating water spray cooling systems into solar panel installations.
