我们考虑一个通用的模型，用于确定一个独立的光伏系统的大小，使用任何辐射图谱中的信息作为能量输入数据。用多元线性回归方法估计模型参数。从一个数值大小的方法获得的结果被用作初始输入数据，以适应模型。建议的表达式允许我们确定的光伏阵列的大小，确定系数范围从0.94到0.98。模型以系统参数和太阳电池组件表面日总辐射的月平均值为自变量。它还表明，所提出的模型可以使用相同的精度为其他位置不考虑在模型的估计。
We consider a general model for sizing a stand-alone photovoltaic system, using as energy input data the information available in any radiation atlas. The parameters of the model are estimated by multivariate linear regression. The results obtained from a numerical sizing method were used as initial input data to fit the model. The expression proposed allows us to determine the photovoltaic array size, with a coefficient of determination ranging from 0.94 to 0.98. System parameters and mean monthly values for daily global radiation on the solar modules surface are taken as independent variables in the model. It is also shown that the proposed model can be used with the same accuracy for other locations not considered in the estimation of the model.
