摘要

我们评估了GTI-DIRINT模型用于估算直接法向辐照度(DNI)、漫射水平辐照度(DHI)和从测量的阵列平面(POA)辐照度估计全局水平辐照度(GHI)。我们的动机是探索将地面辐照度测量限制在POA的可能性，以降低仪器成本。我们利用7个First Solar光伏电站的气象数据对GTI-DIRINT模型进行了检验，并将以POA为输入的GTI-DIRINT模型与以GHI为输入的DIRINT模型进行了比较。

Evaluating a model to estimate GHI, DNI, & DHI from POA irradiance

We evaluate the GTI-DIRINT model for estimating direct normal irradiance (DNI), diffuse horizontal irradiance (DHI), and global horizontal irradiance (GHI) from measured plane-of-array (POA) irradiance. Our motivation is to explore the potential for limiting ground-based irradiance measurements to POA to reduce instrumentation costs. We test the GTI-DIRINT model using meteorological data collected at seven First Solar PV power plants, comparing the GTI-DIRINT model which uses POA as input to the DIRINT model which uses GHI as input.
