Good afternoon, I think it would be a good idea if Valentin software developers make a wish list in the Forum for the users so they can have a feedback of what is more important and required by the costumers/users and if they are mentioned very often try to include them in the following releases. Here are my wishes ? 1- More stand alone inverter/chargers/components brands, as Victron, Steca, Ingeteam, Solarwatt 2- Bigger area to develop bigger projects 3 - A better relation with 3D software as Sketch-up 4 - The possibility of include some images/pictures or even text in the final report (for clients would be interesting if we can include in …

If I analyze the same off-grid system—with the same PV array, the same consumption, and the same PV inverters—but change the battery configuration from 1 to 2, the fuel consumption is 11,000 liters in the first case and 20,000 liters in the second. How is this possible? Furthermore, the configurations shown on the screen do not reflect reality; since both are three-phase inverters, only one battery inverter would be needed—not three—but the software does not allow me to change this. 1) 2)

Hello, I am having an issue with the tool which snaps the panels into alignment with existing panels. Previously this has always worked fine, I drag the panel nearby to an existing array or panel and it will show the grid and then show the dialogue to confirm I'd like to snap the panel into the array - but since the latest update it's been very temperamental, most of the time not working or the grid only comes up for a second then disappears. It makes moving arrays around difficult and hard to get them correctly lined up - any advice? I've tried turning the tool on and off in the toolbar but no luck. Thanks in advance

I have 2 scenarios in a photovoltaic installation 1) 500 kWp + 1 MWh BEES 2 500 kWp + 2 MWh BEES Self-consumption is 67.5% for option 1 and 69.7% for option 2, with an energy self-sufficiency rate of 78.7% and 80.4%, respectively. With the production of both being 792,857 kWh In the first option, 257,778 kWh are fed into the grid. In the second option 240,005 kWh are fed into the grid. How is this possible, given that in the first option there is surplus photovoltaic energy once the batteries are full? There ought to be a greater difference between one option and the other. In the first option I have 4 Sungrow PowerStack ST255kWh-125kW-2h (ST255CS-2h) and in the second …

Dear PV*SOL Support Team, I would like to clarify how PV*SOL models local and global maximum power point tracking. So far, I have only been able to run the simulation with a one-minute time step, and my understanding is that the global maximum power point is determined at each step. Could you please confirm whether this interpretation is correct? In practice, an inverter may track a local maximum between periodic global scans, with scanning intervals of, for example, 10 or 30 minutes, depending on its settings. I would like to reproduce this behaviour to obtain simulation results that better reflect actual inverter operation. Is it possible to: Select local MPPT tracking …

Hi, is there a possibility to download PV SOL Premium 2024?

Hello everybody, Is it possible to swap from a model of solar module to another (for example swap from JaSolar 275p to Canadian Solar CS6K) without deleting the former module mounting or coverage? Kamal

Good morning, We are trying to move a perpetual license from an old laptop to a new laptop. The license has been deactivated on the old laptop and we have the serial number. However we cannot activate this on the new device as the version of PV*SOL premium available to download online is too new, according to the activation guide it needs to be older than April 2026. Please could you provide a link to download the newest version of PV*SOL premium that is compatible with the perpetual license model, Thank you.

Good morning, Can you request that this photovoltaic module be added to the pvsol database? It would be helpful to have it in order to optimize the time spent entering data manually. I have attached the technical specifications for the solar panel. I look forward to hearing from you. Kind regards. LR8-66HVD 640-665M （30-30&15框）- Scientist-BGV01 20250605- EN .pdf

Hi everyone, I am experiencing an issue in PV*SOL 3D visual geometry regarding the module azimuth and simulation results on a South-facing roof with reverse mounting structures (tilted to the North). Issue Description: I have a roof pitch oriented towards the South. I installed a mounting structure/elevation system on this roof to invert the pitch so the PV modules face North. Even after selecting the highest roof edge (Reference Edge at the ridge/cumeeira) as the reference, the simulation engine still considers the global orientation/azimuth of the base roof (South) instead of the actual module orientation (North). …

Dear All, how to increase the power definiton of the PV generator it only allows me up to 72500Kwp and I need 100000Kwp of power generation

I am trying to do a design for a building that has been up for a few years now and the image on PVsol seem to be from 2022. Is there a way to update this?

Hi I'm fairly new to PV*SOL. I'm working on a project, with multiple technique rooms on top of the building, spaced evenly out. I have modeled each technique room individually as well as the space between these, as we are considering whether to place the PV in between. I've modelled everything an placed the PV modules, but now I realize, that the building doesn't have the correct orientation Rotating each building doesn't really work that well, as you can see 😅 Is there a different way of doing this? The easiest would be, if it was possible to change the orientation of the site. Thanks in advance for your help 🙏

Hi everyone, Has anyone else run into this with a 3D model imported from Rexplorer? Parts of the roof plane show up as white hatched areas and I can't place any modules on them — they don't respond to a right-click either. What is the proper way to solve this? Thanks in advance!

Hi, When stringing is there a process after choosing meander? Most of the time when meander is chosen and then cable design. It automatically keeps the stringing as simple. Am i missing a step? Thanks

Hello, can someone help me configure the Feed-in Concept so that it matches the current principles for calculating the kWh price in Croatia (new rules effective from January 1, 2026)? According to these rules, if the consumer takes less energy from the grid than they send to it, the price of the exported energy is €0.085/kWh. If the consumer sends more energy to the grid than they consume from it, then the price of the exported energy is calculated using the formula: 0.085 × (consumed / exported) Thank you in advance.

Been having an issue with the PVSOL export simulation results where the simulation results aren't showing the tab labelled "Current & Voltages". This hasn't been an issue previously, and even on more recent projects I've managed to get this info per inverter just fine. I've attempted clearing some of the error messages on the design (feed-in and grid tariff, dimensioning factors, etc.) to no avail neither. Now I'm thinking that maybe its a case of having too many inverters in the design itself? Not entirely sure. Any help with this would be greatly appreciated.

Hello everyone, I need to provide the following generation curves for a DG (Distributed Generation) feasibility study, and I would like to know how to generate them in PV*SOL: Daily generation curve with hourly resolution (typical sunny day and typical cloudy day). Annual generation curve with monthly resolution. For reference, I have attached the project simulation. Any guidance or suggestions would be greatly appreciated. Thank you in advance!

Good morning. I would like to know how to configure the program to simulate a 300 kW grid connection limit and ensure that no energy is fed back into the grid. In other words, it can only draw 300 kW from the grid and cannot feed any power back into it.

I recently noticed that the load data for consumption seems to not match the provided data, as in the annual course table that you can edit does not match the consumption graph shown above, I have attached two screenshots showing the issue, one user inputted, with all months and days being identical, and Brazil/Block of flights to show that the error applies to both default and user-input data. My guess is a calculation issue, as the output data seems to be higher on months with 31 days and lowest in February with the fewest days. Any help is appreciated on either fixing the bug or making a load profile to counter the issue, it's only a 3% difference but that ca…

Hello everyone, I am redesigning the string layout of an existing PV system after removing some modules. The physical module layout should remain as close as possible to the existing installation. In the new design, every string must have exactly 19 modules in series. I have two separate questions: 1. Some 19-module strings have to run across several separate roofs. The roofs have the same tilt and orientation. Is it possible in PV*SOL to define one electrical string whose modules are placed on different separate roofs? 2. Independently from that, some strings have to be connected in parallel, for example two separate strings with 19 modules each …

Hello, Is there a way to download 2025 R4? I still have previous licensing and I would like to switch from old device to new one. Thanks in advance

Good afternoon, I have a question, I am currently configuring an off-grid system with and without a generator, I am applying a hybrid inverter in this case "Huawei 5Ktl- L1" and batteries also "Huawei LUNA2000-(5-30)-S0" Since the inverter is hybrid, I do not need a battery inverter, however the program always shows me the option with a battery inverter... This is due to the fact that the program does not have the capacity to read a hybrid inverter or is me doing something wrong? All the toturials and videos I watch don't use hybrid inverters so I didn't find much help. Thanks
