As is already known, solar photovoltaic (PV) technology is a widely accepted technology for power generation worldwide. However, it is scientifically proven that its power output decreases with an increase in the temperature of the PV module. Such an important issue is controlled by adopting a number of cooling mechanisms for the PV module. The present experimental study assesses the effect of a fanless CPU heat pipe on the performance of a PV module. The experiment was conducted in June in real weather conditions in Yekaterinburg, Russian Federation. The comparative analysis of two PV panels (i.e., cooled, and uncooled) based on the electrical energy, exergy performance, economic, embodied energy and energy payback (5E) for the two systems is presented and discussed. The key results from the study are that the average temperature reduction from the cooling process is 6.72 °C. The average power for the cooled panel is 11.39 W against 9.73 W for the uncooled PV panel; this represents an increase of 1.66 W for the cooled module. Moreover, the average improvements in the electrical efficiency, and embodied energy recorded for a cooled PV panel 2.98%, and 438.52 kWh, respectively. Furthermore, the calculations of the levelized cost of energy (LCE) for the cooled PV panel indicate that it can range from 0.277-0.964 USD/kWh, while that for the uncooled PV panel also ranges from 0.205-0.698 USD/kWh based on the number of days of operation of the plant.
众所周知，太阳能光伏（PV）技术是一种在全球范围内被广泛接受的发电技术。然而，科学证明，其功率输出会随着光伏组件温度的升高而降低。通过采用多种光伏组件冷却机制来控制这一重要问题。本实验研究评估了无风扇CPU热管对光伏组件性能的影响。实验于6月在俄罗斯叶卡捷琳堡的实际天气条件下进行。对两个光伏板（即冷却的和未冷却的）基于电能、火用性能、经济性、隐含能源和能源回收期（5E）进行了比较分析，并进行了展示和讨论。该研究的关键结果是，冷却过程的平均温度降低了6.72℃。冷却后的光伏板平均功率为11.39W，未冷却的光伏板平均功率为9.73W；这意味着冷却后的组件功率增加了1.66W。此外，冷却后的光伏板的电效率和隐含能源平均分别提高了2.98%和438.52kWh。此外，冷却后的光伏板的平准化能源成本（LCE）计算表明，根据电站的运行天数，其范围可以从0.277 - 0.964美元/千瓦时，而未冷却的光伏板的平准化能源成本范围也为0.205 - 0.698美元/千瓦时。
