Abstract

In order to solve the problem that the output characteristics of photovoltaic modules are affected by ice coating in winter, a single-phase closed-loop photovoltaic power generation experimental platform is built. And based on the outdoor environment in Urumqi in December, the influence of the change of ice coverage area, ice thickness and ice inclination angle on the output power and power loss rate of photovoltaic modules is analyzed. The experimental results show that the output power of photovoltaic modules decreases rapidly with the increase of ice cover area, and the power loss rate increases with the increase of filling factor; with the increase of ice cover thickness, the change trend of output power is first stable and then continues to decrease, and the corresponding loss rate begins to increase; the increase of ice cover angle will improve the light refraction and shielding effect caused by ice cover to a certain extent.
