jimbob22 Posted March 10, 2018 Share Posted March 10, 2018 Hi we are diagnosing issues on a site.When comparing measured irradiance from an in plane pyranometer which the predicted values from PVsyst, which of the PVsyst predicted values should we use for comparison?GlobInc or GlobEff?.Thank you Link to comment Share on other sites More sharing options...
André Mermoud Posted April 17, 2018 Share Posted April 17, 2018 GlobInc is the irradiance on the plane, calculated by the transposition model. GlobEff is the irradiance effectively falling on the PV modules, after optical losses like shadings, IAM or Soiling. You should compare with GlobInc of course.
