hdseo Posted October 2 Posted October 2 Usually, the PR is calculated by hand as below, so the review is possible. E_Grid ÷ (GlobInc × Module Area × Module Efficiency) = PR However, for this case as attached, the PR calculated by hand is not matched with the PR which PVsyst calculated. - PR calculated by hand = 25,164,653 ÷ (2,042.7 × 65,631 × 0.2294) = 81.8% - PR PVsyst calculated = 82.1% There is a gap of 0.3%. Can I know where this comes from? Maybe unused energy (grid limitation) ? That is 3.11%, but, here 0.3%. Thank you so much for reading upto here.
