RobS Posted April 16, 2019 Report Share Posted April 16, 2019 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?

developer_fw Posted April 16, 2019 Report Share Posted April 16, 2019 Hello Rob, I'd be glad to investigate the matter. Might it be possible to send me the project file(s) via private message? And please tell me the exact versions of PV*SOL (e.g. 2018R8) you used for the simulations. Best regards! Frederik Quote Link to comment Share on other sites More sharing options...
RobS Posted April 16, 2019 Author Report Share Posted April 16, 2019 Hi Frederik, That would be great thanks I have a couple of examples. The PVSOL file is too large to send via the forum private messaging do you have an email i can use please. Best regards, Rob Quote Link to comment Share on other sites More sharing options...
