Abstract

Based on the test project of a small photovoltaic power station in Hainan, this paper collects the power generation data of p-type and n-type cell modules in 2021. Then, the single-watt average power generation performance of the two modules in different months is compared and analyzed, so as to verify the superiority of n-type modules in power generation efficiency compared with p-type modules. The effects of irradiance and temperature on the power generation performance of the two modules are tested under the actual working conditions of photovoltaic power station. The results show that the n-type modules have better low irradiation performance. Also, it is proved that the thermal stability of n-type module is better, which is consistent with the smaller power temperature coefficient of n-type module in theory. By studying the DC power generation of the two modules in different weather, it is found that the n-type module also maintains superior power generation performance under the condition of sudden drop of irradiance.
