Abstract

A photovoltaic array composed of YL250P-29b type polycrystalline silicon solar cells packaged in series at our school is taken as the research object in order to improve the efficiency of photovoltaic power generation. The rationality of the numerical model was verified by comparing the experimental data and simulation results of artificial ash accumulation. Based on this model, the effects of wind speed, irradiance, ambient temperature and ash density on the temperature of photovoltaic modules are simulated and analyzed. According to the empirical formula of photoelectric conversion efficiency and output power, the influence of the above environmental factors on the output characteristics of photovoltaic modules was explored. The results show that there is a negative correlation between PV module temperature, photoelectric conversion efficiency with wind speed, and positive correlation with irradiance, ambient temperature and ash density. There is a negative correlation between the output power of photovoltaic modules with ambient temperature and ash density, and a positive correlation with wind speed and irradiance. Within the scope of this study, the correlation order between each environmental factor and PV module temperature and photoelectric conversion efficiency is： ambient temperature> irradiance>wind speed>ash density, and the correlation order with output power is： irradiance>ash density>ambient temperature>wind speed; For every 1 ℃ increase in ambient temperature, the temperature of photovoltaic modules also increases by about 1 ℃, and the photoelectric conversion efficiency and output power decrease by about 0.06% and 0.4%, respectively. Ash accumulation reduces the temperature of photovoltaic modules and increases the photoelectric conversion efficiency, but it will greatly reduce the output power of photovoltaic modules.
