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.
