As a double check I run my own Excel calculation and when comparing that to the PV Sol calculation I find a difference which I hope you can explain. Please look at the attached file; Financial Analysis; First year saving. SEK 5.233,68 Then look at the cash flow Table year 1; Electricity saving. SEK 5.131,06 Should´t these two figures be the same?

Next Total Payment from Utility in First year is SEK 6.037,03 I would expect that to be equivalent to Feed-in / Export Tariff in the Cashflow table or ?

Dear sir, Can we simulate Total cross tied or Bridge link scheme on PVSOL?

Hi to everyone, how can be possible simulate an half cut cell modules like trina TSM PE14H ? Thanks

Hello everyone I'm looking for a good source of information for solar panel software. My dad's company has been relying on an external service to do the calculations and drawing of the solar designs, but he wants to do it himself because the external service asks loads of money and are sometimes 2 weeks late with their reports. We use the solmetric suneye device to measure shadow, this data can be imported to the solmetric software called PV designer. However, PV designer is not that great. There's no auto-filling the roof you drew if it's not a rectangle, there's no option for custom no-
