Update: tried opening my project files using the 2025 version and it shows this error, which means we are not able to use PVSol at all

Dear Valentin team, All PVSol users in our team are currently experiencing a crash that has never happened before in previous versions. On the 2026 R1 and R3 versions, while we're running the simulation, the monitor goes black with an error message "Device not working properly" and the entire laptop restarts. When it restarts, our changes are not saved and this is making the software unusable. There are 3 users in our team and we are all currently unable to complete any designs because of this issue. Our laptops have been able to to run all versions 2024 and 2025 with no issues, the crash only started when we updated to the 2026 versions. Is there a way to resolve this? Many Thanks, Chloe

Nice design, how do you get PVSol to string it properly if the module areas are in 2m wide bits of roof?

Hi Frederik, It's been more than 2 years since this feature request, is this something we can expect to be released anytime soon? Best Regards, Chloe

Hi Ben, from the log I can see the following: 2025-06-16 11:19:02,826 [7392|8|Load] Load() - error during unzip. Not all files available. Anti-Virus? Many Thanks, Chloe

Hi Ben, Just downloaded it and tried to reopen, same error message:

Hi there, I have the same issue where I cannot load a .pvprj file sent to me, what is the cause of this? I have PVSol Premium 2025 screenshot of error message below (sensitive data redacted):

How often does the climate data update and when are we expecting the next update?

I agree with most of the suggestions already sent to this topic and would like to add my own wishlist: Parapet wall integration that wraps around the whole building, tricky if it's a double pitched roof as it will create parapet wall along the ridge Panel swapping feature for different module dimensions, I don't understand why we don't have this already and why the different panel dimensions is an obstacle to this The option to manually string the panels, useful for modelling already existing systems or if there were any changes to the stringing post-installation I echo the need for a bigger design are so we can model bigger projects PVSol is one of the best solar softwares we currently have but hope this thread can help it become the best solar software to use

Dear Valentin team, I really wish there was a way to swap between panels of different dimensions without having to recreate the arrays from scratch. The Replace Module button spits out an error if swapping into a module of different dimensions and I cannot understand why that is. Is this something we can expect to see in upcoming versions? I find this to be one of the most time consuming tasks on PVSol and changing the panels should be easy to do. It's a shame that such a powerful (and expensive) software lacks this feature but a free web-based software like SolarEdge designer can do this no problem. Regards, Chloe
