The purpose of this study is to improve the electrical performance of the photovoltaic (PV) module by using the sunlight concentration and cooling technique. Three identical polycrystalline PV modules were used in the experiments; ordinary PV module, concentrated PV module (CPV) and CPV system with cooling technique. The experiments were performed in a clear day on September 24th in Duhok, Iraq. The cooling system is developed by the water flowing on the front of the PV panel. The operating temperature of the CPV is kept very low by the cooling system, i.e., 30–35 °C. The maximum power output of CPV system and CPV system with cooling compared with the reference PV module is improved by the rates of 8% and 18.5%, respectively. In addition, the maximum percentage increase in the electrical efficiency of the CPV system and CPV system with cooling technique is 6.5% and 17.7%, respectively. The CPV with the cooling system delivered more energy than the other two cases. According to the economic analysis of a typical domestic use, the payback period is 3.77, 3.52, and 3.23 years for the stand-alone PV module, CPV system and the CPV with active cooling system, respectively.

本研究的目的是通过使用阳光聚集和冷却技术来提高光伏 (PV) 模块的电气性能。实验中使用了三个相同的多晶光伏组件；普通光伏组件、聚光光伏组件 (CPV) 和带冷却技术的 CPV 系统。试验于 9 月 24 日在伊拉克杜霍克的晴天进行。冷却系统由在光伏面板正面流动的水形成。CPV 的工作温度通过冷却系统保持在非常低的水平，即 30–35 °C。与参考光伏组件相比，CPV 系统和带冷却的 CPV 系统的最大输出功率分别提高了 8% 和 18.5%。此外，CPV 系统和采用冷却技术的 CPV 系统的电效率的最大提高百分比分别为 6.5% 和 17.7%。带有冷却系统的 CPV 比其他两种情况提供更多的能量。根据对典型家庭使用的经济分析，独立光伏组件、CPV系统和带主动冷却系统的CPV的投资回收期分别为3.77、3.52和3.23年。
