摘要
作为影响光伏系统发电量的重要因素,光伏板接收辐射量和最佳安装角度备受重视,但由于地域、时域以及计算方法差异等问题,导致学者们得到的结果差异较大。通过理论推导对多地光伏安装角度进行分析,以银川、北京、哈尔滨3地光伏的接收辐射量为例进行分析。结果表明:平单轴和平斜单跟踪光伏可有效提高光伏系统接收辐射量,分别较固定式提高20%和30%以上;面板安装倾角/倾角在0°~30°内提升明显,超过30°后提升较小且存在最优值。最佳安装角度与纬度有密切关系,通过对部分地区最佳安装角度拟合得到其与纬度相关函数,结果具有高度相关性,可为国内光伏最佳安装角度提供参考依据。
The radiation received by photovoltaic system and the installation angle of photovoltaic panel are important factors affecting the power generation of the photovoltaic system.However,due to the calculation method and other problems,many scholars have different calculation results.The received solar radiation of photovoltaic in Beijing,Yinchuan and Harbin is analyzed by theoretical derivation,and the installation angle of photovoltaic in many places is calculated and analyzed.The results show that the flat single axis and inclined single tracking photovoltaic can effectively improve the received radiation of the photovoltaic system,which can be increased by more than 20%and 30%respectively compared with the fixed type.In the 0°~20°panel installation angle,the increase is fast,and the change is small and there is a maximum value when the angle exceeds 30°.The optimal installation angle is closely related to latitude.The correlation function between the optimal installation angle and latitude is obtained by fitting the optimal installation angle in some regions,and the results are highly correlated,which can provide a reference for the optimal installation angle of photovoltaic in China.
