Hi,
I did a simulation using 620W Solar Panels with different brands, same capacity and inverter.
With JA Solar 620Wp, the PR of the system is at 81%. While with Panasonic 620Wp, the PR is at 86%. Please note that the datasheet of the 2 solar panel brands are very identical.
With these information, I can say that Panasonic is much more efficient panel than JA Solar. But, checking the datasheet they are very similar so I'm quite confuse how come I cannot reach or similar PR for both panels.
Could you please explain how PVSol simulate and forecast the yield?
Thank you.
