摘要

在操作期间模块温度的升高不利地影响光伏(PV)太阳能系统的功率转换效率(PCE)。为了提高光伏太阳能系统的PCE,开发并测试了与相变材料(PCM)和ZnO掺杂PCM集成的多管铜冷却框架。测试采用单晶硅模块(每个50W)、太阳能表、温度传感器、数字风速计和万用表。绘制了测试光伏系统的I–V曲线。结果表明,传统光伏系统中午的组件温度和电效率分别为52.8°C和12.29%。将PCM/ZnO与光伏系统集成,降低了5.68%的模块温度,提高了5.04%的电效率。ZnO掺杂PCM填充的多管铜冷却框架由于框架内部的自然对流和传导传热作用,显示出更好的冷却性能。图形摘要

Efficiency enhancement of photovoltaic solar system by integrating multi-pipe copper frame filled with ZnO-doped phase change material
The increase of module temperature during operation adversely affect the power conversion efficiency (PCE) of a photovoltaic (PV) solar system. In an attempt to improve the PCE of the PV solar system, multi-pipe copper cooling frames integrated with phase change material (PCM) and ZnO-doped PCM have been developed and examined. Monocrystalline silicon modules (50 W each), solar meter, temperature sensor, digital anemometer and multi-meter are employed to conduct the tests. The I–V curves are plotted for the PV systems tested. The outcomes unveiled that the module temperature and electrical efficiency of conventional PV system at noon were 52.8 °C and 12.29% respectively. Integrating PCM/ZnO with PV system has reduced 5.68% of the module temperature and increased the 5.04% of electrical efficiency. The multi-pipe copper cooling frame filled with ZnO-doped PCM shows better cooling performance owing to the role of natural convection and conduction heat transfer inside the frame.
