摘要
以常州新北区为例,基于太阳高度角季节的变化特性,采用季节可调式支架,获得了支架在不同季节下的最佳倾角,分析了5 kWp屋顶光伏发电系统的实际投资并预测了25 a的发电量。结果表明,光伏电站使用季调式支架具有较高的经济和实用价值,值得推广。
Based on the seasonal variation characteristics of solar elevation,the seasonal adjustable bracket is adopted to obtain its best angle in different seasons.Taking Xinbei District of Changzhou City for an example,it analyzes the actual investment of 5 kWp photovoltaic power system on the roof and forecasts the 25-year electricity generation.The results show that the photovoltaic power station with the seasonal adjustable bracket has higher economical and practical value,which can be worth popularizing in photovoltaic power stations.
