Are LID losses stated by the module manufacturer included in PR calculations?

Hello. I have created a design in 3D. I would now like to set the shadow effect to, for example, 5%. How do I do that? Risvænget 6.pvprj

Hello I want to use the pv panel from JA Solar JAM66D46LB. Why aren’t they in the database? I can’t find them.

Hello, Iit possible to create a graph of daily power of the inverter in PVSol Program?

Good afternoon, I hope you are well. Would it be possible to obtain or generate the DWG drawings showing the electrical connections per inverter only, rather than as a combined layout based on the overall plan or PV*Sol configuration? I look forward to your comments. Kind regards.

What metereological databases PV*SOL uses.

Hello again. I would also like to know how the average night consumption is calculated. From what time to what time?"

Hi PV*Sol! Got a issue with the program today, for some reason the information about the amount of modules and the kWp value does not show anymore. I have attached a picture of the issue. My PC crashed today as well, i do not know if the issue is related to my bluescreen. But this information does not show anymore, my colleagues with the same version does not have the issue. All of us are PV*Sol Premium users with the 2026 R3 release. If you want to take this inquiry in a chat instead of the forum, no issue. Thank you for all help provided.

Hello Can I simulate only a system with a battery without PV? "In the attached file, can I simulate what would happen if AI were controlling the battery? Bruno.pvprj

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…

po instalacji testowej pvsql 2026, nie moge korzystać z wersji 2022 którą zakupiłem, odinsgtalowanie pvsql 2026 nic nie daje

Hello can we configure pvsol such then solar should charge battery first and when power from solar is high then 1) it should charge battery first 2) if power is extra then that power cover load 3) if still power is left then that should goes to utility

Does anyone know if PVSOL is able to model DC couple battery energy storage systems? In the UK DNOs regard AC coupled BESS inverters as generators and DC couple BESS can also make use of DC power shaved off at peak generation by undersized AC inverters

hello everyone is there a way to extend all the barred areas, e.g. like edge distances? many thanks in advance and best regards

am working on a grid-tied with batteries project, and idk why there alwayes a grid consumption, no matter how small the load is compared to the PV or the battery Is there a way to force load to consume from the battery first, or to prevent the grid import

Hi, I was wondering, is there an option to undo changes in PV SOL, other than not saving and simply opening the last saved version of your file? Something in the line of Ctrl+Z in MS Office. Thanks!

Hi, I run a UK based solar installation company. With increased demand we are looking to outsource some of our solar design work that is currently undertaken in house primarily for domestic UK homeowners. We are looking to partner with an individual or company that can provide the following design work; String diagrams SLD/Schematics Inverter calculations Cable calculations Mounting system report Bill of Materials for the product lines we use If you think you can help please email Jason on jason@tethys-energy.com Thank you.

"Hello, I have a question regarding the following. I have designed two nearly identical systems in PVSOL. Both have 4.4 kWp of PV capacity, the same battery type with 19.2 kWh storage, and both use a hybrid inverter: a Growatt SPH3600TL BL-UP and a Solis S6-EH1P3.6K-L-PLUS. There is such a large difference in battery losses that I don’t understand the cause. Who can help me? I am uploading a spreadsheet with all PVSOL input values for the battery, the PV inverter, and the battery system. With the Growatt configuration, the loss is 819 kWh/year, while for the Solis, it is only 233 kWh/year." Growatt Solis I hope someone can help me out on …

Could you tell me which factors influence the PR (Performance Ratio) value? -All of them. I have heard about an RP value (Reference Performance / Reference Yield Ratio). Are you familiar with an RP value? Thank you

Guten Tag, ich möchte Module mit verschiedenen Ausrichtungen auf einem Flachdach platzieren. Das habe ich aktuell in PV*SOL mit 2 Modulflächen realisiert, siehe Bilder. Allerdings hätte ich gerne eine Ansicht, in der ich alle Module auf einen Blick sehen kann. Daher habe ich probiert ob ich die Module auch mit 2 Belegungsflächen platzieren kann, dann bekommen aber alle Module die gleiche Ausrichtung. Gibt es noch irgendeine Möglichkeit, wie man verschiedene Ausrichtungen auf einem Dach realisieren kann und dann alle Module auf einen Blick sehen kann?

Hi everybody, I'm sizing a hybrid system, grid connected with a battery bank. I can't find where and/or how I can do the settings doe Depth of Discharge and State of Charge I hope someone can help me out Many thx And for sure have a blessed and healthy 2026

Sehr geehrte Damen und Herren PVSOL berechnet die Leerlaufspannung eines Moduls über die Formel Ich habe bei der Planung einer Anlage das Modul: Trina Solar 460W (TSM-460 NEG9R.28 Vertex S+) genutzt Laut Datenblatt liegt die Leerlaufspannung bei 53,8 V, der Temperaturkoeffizient für die Leerlaufspannung (Voc) liegt angegeben bei -0,24%/°C. Temperatur min = -10°C angenommen Bei diesen Werten für die Berechnung der Leerlaufspannung ist eine Leerlaufspannung von 62,2 V Berechenbar PVSOL gibt die Leerlaufspannung wie unten ersichtlich mit 60,1V an Wieso ist das so?

Hello, We have a internal discussion about how to calculate DC cables. I have been told that it its 2 way (go and return) including the extra lenght of the connection cables. My colleague thinks it is one way including modules. In PV-Sol there is been written 1x go and return. What length must i put in with a 100mtr from inverter to module to calculate te totall loss. is it (a) 100 + connection cables modules. ±140mtr (b) 100 + connection cables and return ±260mtr

Hi, I wanted to copy this inverter and add a new inverter whose specifications are close to the copied inverter. Do I need to add the MPPT numbers of Max. Input Current (A)=30, Max. Short-Circuit Current (A)=37.6 for new inverter or is there no need to add the numbers? New inverter: This is where I need to enter the numbers: With the above specifications, what number should I enter specifically in the boxes?
