This paper presents the optimization of parameters involved in the application of air assisted water spray on the PV panel surface. The effect of spray cooling on panel performance was examined. The increase of cell temperature, hence a decrease of electrical efficiency, was obtained experimentally for a conventional PV panel. In order to prevent a decrease in efficiency, effective parameters were determined. These parameters were examined in 3 levels as spraying time, spray flow rate, nozzle air flow rate, nozzle to panel distance and solar irradiance. Then, 32 experiments were carried out according to the experimental plan obtained using Response Surface Method. As the result, optimum values for highest electrical efficiency were obtained as 49.8990 s for spraying time, 0.0180 m3/h for spray flow rate, 2 m3/h for nozzle air flow rate, 50 cm for nozzle to panel distance and 700 W/m2 for solar irradiance. The most effective parameters were determined to be spray flow rate, spraying time and solar irradiance, respectively. An appropriate correlation with these parameters was proposed for electrical efficiency.

通过喷雾冷却对光伏面板的运行参数进行优化

本文介绍了空气辅助喷水在PV面板表面上应用时涉及的参数的优化。检查了喷雾冷却对面板性能的影响。对于常规的PV面板,通过实验获得了电池温度的升高,从而降低了电效率。为了防止效率降低,确定了有效参数。这些参数在3个级别中进行检查,例如喷涂时间,喷涂流量,喷嘴空气流量,喷嘴到面板的距离以及太阳辐照度。然后,根据使用响应面法获得的实验计划进行了32个实验。结果,获得了最高电效率的最佳值,喷涂时间为49.8990 s,喷涂流量为0.0180 m 3 / h,喷涂时间为2 m喷嘴空气流量为3 / h,喷嘴到面板的距离为50 cm ,太阳辐照度为700 W / m 2。确定最有效的参数分别是喷雾流量,喷雾时间和太阳辐照度。提出了与这些参数的适当相关性以提高电效率。
