Hallo zina, ja, wir können das Problem bestätigen. Das ist mit der Version 2026 R1 reingekommen und wird dann in der nächsten Version gefixt sein. In der Zwischenzeit einfach einen bestehenden Wechselrichter duplizieren, dann geht es. Beste Grüße, Martin

Hi Dutch Energy Group, I guess you mean a limit for feeding energy into the grid? You can enter this in the options of the AC mains, we call it the maximum feed-in power clipping: The energy management is as described here: https://help.valentin-software.com/pvsol/en/calculation/battery-systems/#energy-management That means that right now, there is no specific option to wait for the solar power to reach the feed-in limit and only then charge the batteries. But we definitely have that on our plan, along with other interesting options that you have with battery systems. Or did you refer to limits for the power that is drawn from the grid? Hope that helps, best regards, Martin

Hi Bruno Lalic, the difference comes from the low light parameters: left: "TSM-705NEG21C.20 Vertex N Bifacial 705 W" right: "TSM-705-NEG21C.20 VERTEX N 2024 705 W" In one case, the manufacturer has chosen the "standard low-light performance", which defaults to the two-diode-model for this module. In the other case, the manufacturer entered low light values himself, that is, defined values for voltage and current at 200 W/m². Hope that helps, kind regards, Martin

Hi FPE, yes, you can do that in PV*SOL. If you have a load profile measured, you can import it in PV*SOL. If you don't have one, you can choose from plenty of options in the database. Then you would enter the schools current electricity price as a from-grid tariff and the "price sold to third party" as the PPA price. After simulation, you can see the resulting ROI and other financial parameters. Hope that helps, kind regards, Martin

Hallo zusammen, seit dem neuen Update von gestern kann ich nicht wie gewohnt, bei der Verschaltung, weitere Wechselrichter einfügen und dort die Modulflächen auswählen. In den zwei Screenshots ist es hoffentlich deutlich zu sehen. Liegt das an dem Update oder habe ich da ein anderes Problem? wie kann ich das lösen? Vielen Dank im Voraus und beste Grüße Zina

We have a lot of customers with a grid power limit, it would be more than welcome to put a grid limit into PV Sol. So the delivery of solar is often 0KW and the grid connection is limited to 125 kW for example. When we install more solar and a battery system also connected to a heatpump, it would be great to have a power limit, so the solar power will charge the battery at that limit or feed the heat pump and so on. Like to hear the possibilities about grid limits.

By choosing panels from the base, Trina Solar TSM-705NEG21C.20 Vertex N Bifacial 705 W, or Trina Solar TSM-705-NEG21C.20 VERTEX N 2024 705 W, which have identical characteristics, in an outdoor setting, I get large differences in production estimates. Why?

Hello, We're looking to produce a commercial PPA for a school on PVSOL. Is there a way we can model the schools annual usage, what they currently pay for grid sourced electricity and a rate of the PPA. for the school to purchase the generated power from the developer? We can then build an ROI into the model. Is it possible to do this on PVSOL?

I just deleted the Documents "Valentin Sorftware" folder (on OneDrive). Then the installation was finished properly. Cheers M.

Dear Solar sun, Thank you for your inquiry. We are discussing the implementation, but we cannot yet give a timeline for it.

Are there plans to introduce this to PVsol?

Dear Anders, Thank you for your inquiry. You have entered the investment costs correctly. Since the customer does not receive a feed-in tariff, delete the pre-set feed-in tariff: Then create a new purchase tariff, enter 2.16 DKK per kWh, and start the simulation. The payback period is two years: JKE VAL.pvprj

Dear Aluija, Thank you for your inquiry. With PV*SOL, you can extrude a 3D model of a building based on a map section from Google Maps. Using the Google Solar API, an orthophoto and elevation data for the map section are imported into PV*SOL. How this works is described in our help documentation. There is also a video tutorial (with English subtitles) that explains this planning method. To be able to use the Google Solar API data in PV*SOL premium, a valid API key is required, which can be created quickly and easily at Google. A Google account with stored payment information is required. If you don't yet have an API key, you can still extrude a 3D model of a building based on a map section without the orthophoto and elevation data. We demonstrate this planning method in this video tutorial.

Hello! Thank you very much for the clarification! Could you please let me know exactly where I can find the Production Forecast? Or how to display it as a bar chart? Kind regards.

Hi everyone, I’d like to ask if it’s possible to import 3D images or models from Google Maps into PV*SOL to use them as a base for modelling the surroundings (buildings, shading objects, terrain, etc.). If anyone knows whether this feature is supported, or what steps or intermediate tools can be used to bring a Google Maps 3D model into PV*SOL, I’d really appreciate some guidance. Thanks in advance!

Hi. I want to use the financial calculation. I haven’t tried that before. I have a price for a system of 650,000 DKK. I have entered that. Is what I’ve done correct? I know the customer pays 2.16 DKK per kWh. So I would like to enter this fixed price per kWh, and then use PV solar to calculate the payback time. How do I do that? Thanks. JKE.pvprj

Hallo Gerald, vielen Dank für deine Nachfrage. Leider gibt es noch keine Möglichkeit, in der Wirtschaftlichkeitsberechnung eine Bestands- und eine Neuanlage gemeinsam zu berücksichtigen.

Dear Miro, Thank you for your inquiry. Unfortunately, spot prices are not yet implemented in PVSol.

Dear J. Esteban, Thank you for your inquiry. The projected daily generation curve with hourly resolution (for a typical sunny day and a typical cloudy day) can be found in the Diagram Editor after you have performed a simulation with hourly resolution: The projected annual generation curve with monthly resolution can be found under ‘Production Forecast’:

Dear Miro, Thank you for your inquiry. These three battery systems are already available. We will contact the manufacturer and ask them to add the missing products to our database.

Good morning, I would like to check whether it is possible to obtain the following curves in PV*SOL and, if so, in which section of the software they can be found: The projected daily generation curve with hourly resolution (for a typical sunny day and a typical cloudy day). The projected annual generation curve with monthly resolution. I look forward to your response. Kind regards.

Dear support, I just found this relevant topic and my question is if there is some progress regarding spot prices implemented into PVSol. Thank you. Miro

Dear support, please create new items in database regarding battery storage systems in the atachment. Our company is going to use them and we need to simulate them as well. Thank you very much.

Gibt es für dieses Thema schon eine Lösung? Für uns wäre das echt wichtig!

Hab ich gesehen wusste nur nicht, dass der Key auch in der 2025R2 noch geht. Hatte eben die 2025R10 runtergeladen und da ging es nicht. Danke für die Info
