为研究异质结光伏组件的实际发电效果,收集某光伏发电站近两年的发电量数据,得到单块组件的月均发电量。通过对比分析,验证该异质结光伏组件相对于多晶光伏组件在发电效率方面的优越性,且与理论增益相符。通过计算冬夏两季的月均发电量和月均辐照度,证明相比多晶光伏组件,温度升高对该异质结光伏组件的功率影响更小,与理论上异质结光伏组件的功率温度系数更小相符。通过研究组件的单日发电功率,发现异质结光伏组件体现发电效率优势需要有较强的辐照度。
Abstract
To study the actual generation performance of heterojunction photovoltaic modules, the data of the PV power station in these two years is collected, and the average monthly power generation per module is calculated. By comparation, it proves that the efficiency of the heterojunction PV module is higher than the polycrystalline PV module, which is consistent with the nominal value. Based on the average monthly irradiance and power generation in winter and summer, it proves that higher temperature has less negative effect on the power of the heterojunction PV module than the polycrystalline PV module, which is consistent with the theory. According to the power per module on the two days, it is found that the high efficiency of the heterojunction PV module is based on relatively strong irradiance.
