光伏组件倾斜角对并网发电影响的研究

Research on the Influence of the Inclination Angle of Solar Module to PV Grid-Connected Generation

以某地太阳能辐射量数据为基础,研究了光伏组件倾斜角对并网发电的影响,并根据所得数据进行了光资源计算和年度发电量分析,得出结论：以最佳倾斜角为基点,偏离5°以内对发电量影响为0.2%-0.4%,偏离10°左右时对发电量影响为0.7%-1.4%,偏离15°左右时对发电量影响为2.8%-7.8%。

Solar PV generation has been developing rapidly from the beginning of 21 th century in China and other countries.Contrast to the stand-alone system,PV grid-connected system has more economic superiority,which leads to the trend of development in the future.The inclination angle of solar module has great impact on the quantity and price of electricity generated in the full year.This paper analyzes and describes the influence of the inclination angle of solar module to PV Grid-connected system based on solar radiation data obtained from a certain region.
