Dear, The VW ID cars show V2H behavior in the calculations. The car is being discharged for inhouse consumption. Is this a bug and/or is there a way to switch this off? Best regards, Sander

I'm running simulations where I'm defining a photovoltaic (PV) system paired with a battery energy storage system (BESS) and load profiles. The total annual load consumption is 4,019,704 kWh. When I define the battery system, the software (or methodology) suggests a recommended storage capacity from HTW of 4,019.7 kWh. I've tested this across several projects with different load profiles, and I consistently get a recommended HTW capacity that matches the annual load, just converted into MWh (e.g., 4,019,704 kWh → 4,019.7 kWh). This led me to the conclusion that the HTW recommendation is simply based on the total annual load and does not account for the actual PV…

we are trying to size a battery system to an existing PV system. we have put in a load profile and PV system. It has given is a recommendation HTW of 89.5kWh. what does HTW mean

Hello, I just made a 3d model, in agisoft, export it into blender, and finally i'm export it at .obj file and import into PvSol. After import, it looks like no textures (white building) this is my first problem. My secound is i can't put modules on the roof. What to do to prevent the modules from going under the roof? All on the screen.

Hi Is there a way to get the panel field's dimensions on the dimensioning plan?

How can I configure the losses due to unavailability of the plant or because the anti-spill comes in?

Is it possible to somehow generate PV yields in the 2nd, 3rd, 5th... year of its operation? Or do you have to calculate it manually, taking into account the parameters of the components?

Dear Team: I need to limit the feed-in power at the conection point and I don´t sure if the Máximum feed-in Power Clipping is the tool for that. For example, if I have a 100 kW PV plant for use in own consumption and I have a feed-in limit of 25 kW, then would I have to put the Máximum Feed-in Power Clipping in 25% of PV Power at the feed in point? Thanks a lot. Regards, Boris

Hi, Does PV-SOL consider zero production due to snow covering of the panels a few days a year? Here in Sweden is that a fact especially in the middle and north region. Best regards Victor

Hello, I have a question regarding the LCOE calculations and the total energy produced, including degradation. Which formula is used to calculate the total energy over the entire period? When I calculate it manually using the following formula, I get a different price for the energy produced. I'm trying to understand where the discrepancy is. Do you account for degradation only in the first year, or is it considered throughout the entire period?

I have my Model import .obs. The Model was created in SKP. I have the Model with a little PV Anlage and the is not Problem but when i try to calculate the full Anlage hat this Error.

I imported a .obj file into the model as it was easier to create the roof layout in external software, but I noticed that the shading created from the imported models isn't consistent. As shown in the image, there are gaps which pop up that shouldn't, and points of increased shade that don't make sense. I'm wondering if anyone has any solutions or an understanding of how much inaccuracy is being caused by these errors. Cheers.

Hi, Can you please tell me what power rating is used when calculating the annual yield of an inverter - is it the nominal (rated power) or the VA rated (apparent) power? Many thanks.

hello everyone is there a trick how a module can move freely? e.g. rotate? no matter how i place the module it is never straight with the ridge. many thanks in advance and best regards

Hello PVSOL What is the difference between PVSOL Test version and the Premium after we buy it? We are considering to make a choise for PVSOL instead of Pvsyst.

Hi, Can you please tell me what would create the Grid Export in First Year to be so low. Thanks Carl

Hello, I have two questions regarding some projects with the propose to full feed-in the energy to the grid. I update today the PVSOL for de 2025 R3 version and this type of simulation has changed. For exemple, I made a 2D simulation for 12 MW tracking and 4 MWh of battery. It usually charges de battery only from de PV when it starts do generate power and after the battery becames full, it feed-in the energy to the grid. The only shedule that I made is for discharging between 0:00 and 04:00 o'clock. I do not ativate charging periods. With this update, sometimes to charge the battery it consumes from grid (charging from grid). I do not want that, How ca…

Hi, I would like to know if there is a way to input two different tariffs for purchasing energy from the grid. I understand that it is possible to set up multiple dynamic tariffs for selling energy, but I need to do the same for the energy I have to buy. In my case, for the next two years, I have a contract with a fixed price of X per MWh for energy purchased from the grid, and after that, the price changes to Y per MWh. Is there an option to input these values, or is it only possible to do so for the energy consumed and sold from the PV installation?"

Hello, PV*Sol Premium 2025 still has a lot of problems. This is what is happening to me now - when generating energy flows, it divides the energy in a senseless way - 22 MWh of PV production is divided into 22 MWh for direct consumption and 21 MW for the DHW storage. The exact same configuration in 2023 works correctly! ??? Námestie Biely Kríž 1-5.pvprj Námestie Biely Kríž 1 PVSol2025.pvprj

Dear all, Anyone else encounters that saving is not possible? What can you do about this? After 15 sec it says file can not be saved. Thanks veryone!

Does anyone have experience in importing 3d models from pix4dmapper into PV*SOL software? In my case PV*SOL has problems with texture reading. The geometry is fine.

Hello For my Off-Grid System I have: 13,7 kWp and 13 kWh Batterystorage (2 x Growatt GBLI 6532, 6,5 kWh) I use 3 x Growatt SPF 5000 ES Inverters. 3 Strings to create 3 phase current, which is one of the main use cases of those inverters. No separate battery inverters are required. I am not sure how best to represent the system and it´s power generation with the communicating inverters for the generation of three-phase current. In another post I read, that I this Inverter-hybrid configuration is only available with a grid connected system. What downside do I have when I use this work around (instead of use the off-grid configuration)? Which is the best …
