光伏组件发电量与最佳倾角研究——以武汉地区为例

Research on Power Generation and Optimum Tilt Angle of Photovoltaic Module-Wuhan Case Study

光伏系统的性能通常受到天气条件的影响。综合考虑影响光伏组件发电量的因素,构建发电预测模型。并以湖北省武汉市光伏组件为研究对象,逐月、逐季度、逐年的对光伏组件的安装倾角进行了优化设计。结果表明,当光伏组件角度分别为月、季度、年度最佳倾角时,发电量分别增加了11.3%、10.62%、7.53%。因此,对处于武汉市的光伏组件至少按季度进行调整倾角。

The performance of photovoltaic(PV)systems is generally affected by the weather conditions. Comprehensively considering the factors affecting the generation of PV modules,the generation prediction model is constructed in this paper. And then,to optimize installation parameters,the optimum tilt angles were examined by changing monthly,seasonal,and annually,which were obtained from PV modules installed in Wuhan city of Hubei Province. It was found that the power generation increased by 11.3% for monthly,10.62% for seasonal,and 7.53% for yearly. So,it was necessary to vary the tilt angle of the PV modules at least seasonal in Wuhan City.
