PR Calculation by hand

Recommended Posts

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.
