Hello,
Under the latest version of PVSOL performance losses due to low light have jumped vs 2018 version.
On the original on the energy flow chart the low light performance was -0.55%, on the new one it is -3.34%, there are a couple of other minor differences, but that one is the bulk of it. It makes a big difference on overall KWhs/yr.
This is for a flat roof design in ho ch minh city vietnam.
Has there been an update that would cause this?
Best regards,
Rob
