Poster

Spectral and Diffuse-Angular Corrections in PVfit, by Mark Campanelli and Carl Osterwald

This poster shows the derivation of spectral and diffuse-angular corrections using PVfit's formulation of the single-diode model (SDM) with respect to effective irradiance ratio F and cell temperature T. Correction results are compared for a common x-Si module on clearsky, partly cloudy, and overcast skies, where the direct-normal irradiance has been measured in addition to common MET-station data. An implementation of the computation is provided by the tutorial described in the next section.
