June 30, 20206 yr comment_4007 Hello Valentin Team, We simulated a projekt a couple of months back and ended up with 909 kWh/kWp Spez. Jahresertrag. But when i re-run the same simulation today, to my surprise, it increased to 929 kWh/kWp. I know year 2020 has been crazy but is it really this crazy!!!??? ?? Tja, i checked the energy balance results and i could see significant difference in multiple sections. Could you please help me understand why there is a difference here? Do you think it is because of some updates you have made or am i missing something that's changed in my simulation? I would be happy to send you the simulation file and the older pdf report in private message. Sorry i don't have 2 different pvsol files, it's the same file that i re-ran VG, Vishnu Report
June 30, 20206 yr comment_4012 Dear Vishnu, yes, there have been some changes in the simulation core. If you can tell me the program version of PV*SOL that was used to run the simulations in the first place, I can identify the changes that are responsible for the change of the simulation results. You can also have a look at the changelogs here: https://valentin-software.com/en/products/pvsol-premium/ Kind regards, Martin Report
June 30, 20206 yr Author comment_4013 Thanks Martin for a quick reply. To be honest, I did not simulate this back then. I only re-ran it today. The original simulation file was from Feb 2020. I can tell you that. I used PV Sol v7 from April 2020 to re-run it today. I wish i could provide more info.Btw, i've also sent you a private message with files attached But ja, changes in simulation core explains it Thank you Report
