冰雪积聚对太阳能电池板发电功率的影响研究
Study on Influence of Snow and Ice Accumulation on Power Generation Efficiency of Solar Panel
摘要
Abstract
Snow and ice coating is one of the main factors affecting the operation of PV plants in winter,and studying the influence of snow and ice accumulation on the power generation of PV modules can effectively support the power generation prediction and manual de-icing of PV plants in winter.Therefore,the artificial snow and ice coating exper-imental platform is firstly designed and the study on influence of irradiance on snow and ice coating modules is per-formed.It is found that in the range of 200-1000 W·m-2 irradiance,the generation power of PV modules with light ice and snowing coating is still basically proportional to the irradiance.Then,the experiments with different snow and ice densities are performed,finding that the higher the density of the snow layer,the greater the power generation loss caused,but the high density of freezing rain ice overlays with strong light transmission,the generation power of photo-voltaic module is higher than that of snow and fog layers of equal thickness.Finally,it is found through studying the relationship between snow and ice coating thickness and generation power of the power generation of the photovoltaic module that the generation power is basically inversely proportional to the snow and ice coating thickness.When the ice coating thickness is up to 6 cm,the generation loss of the photovoltaic module due to rain freeze and ice coating has reached 93%and that due to ice and snow mixture and half melting snow and ice has reached 99%,and the photo-voltaic module has basically no power generation ability.关键词
