Abstract

Two methods are commonly used to apply spectral corrections based on work from First Solar: 1. A modifier applied to plane of array irradiance (POA) at each time step within energy modeling tools and 2. A modifier calculated from global horizontal irradiance (GHI) and applied to monthly energy model inputs. In this work we quantify differences in spectral correction and energy yield from these two approaches. We find that monthly differences in AC energy yield are 0.0 - 1.0% and annual differences in AC energy yield are 0.1 - 0.3% across a sample of 5 projects. We also review the discrepancy in the hourly calculation method when based on provided precipitable water in comparison to precipitable water calculated based on provided relative humidity data.
