Hello, Thank you for your inquiry. Please send your project file (*.pvprj) to hotline@valentin-software.com so that we can take a closer look at it.

Dear Mark, Thank you for your message. The formula is correct, but the exponent (0.55) is not a standard constant; it varies depending on the battery type and even within a single battery type. PV*SOL Premium uses a value of 1.3278; this value models lithium iron phosphate batteries with sufficient accuracy. Unfortunately, we are unable to model higher accuracy (using variable exponents).

Hello, Thank you for your inquiry. Two planning methods are rather unsuitable: - Using the Rexplorer API, because the L-shaped building (two intersecting gable roofs) is unfortunately not rendered correctly. (However, you can use this method effectively to retrieve building and roof dimensions by drawing layout areas onto the 3D models and displaying their measurements; please see the attached project file.) - Using the Google Solar API, because the image quality is rather poor. We would therefore recommend importing a Bing Maps section, as the image quality is significantly better and allows you to easily position the various obstructions (roof windows, chimney, etc.) based on the texture. We would: - extrude two gable roofs, - adjust the building dimensions accordingly, - disable building collision, and - overlap the two building sections. In this video tutorial, we demonstrate how to assemble a complex roof from multiple roof sections using an L-shaped bungalow as an example. (Please use the English subtitles for translation.) The disadvantage of planning with a Bing Maps section (compared to the Rexplorer API and Google Solar API) is that you cannot automatically account for shading caused by the church tower and the tree (located northwest of the house). In this case, you must manually insert the objects that cause the shading. Rugendorf with Bing Maps and extrusion.pvprj Rugendorf with Google Solar API.pvprj Rugendorf with Rexplorer.pvprj

Hello, Thank you for your inquiry. If you wish to position elevated modules in an open space or on a flat roof, you must first define the mounting system. You cannot rotate the mounting system. If you wish to position a second module table next to the first one with a different orientation, create a second mounting system with the new orientation. We explain how to define and position a mounting system in this video tutorial, starting at the 4-minute mark:

Hello. I am leaving my current position, and as a result I would like to change the email address associated with our PV SOL license. How can I do that?

Hello, I tried this software maybe year or two ago, tried it again now, and seems I still have shading issues with imported models. I've checked and this impacts not only rendering but calculations also I guess. Is there workaround or fix? I have crazy results with this glitch. I don't know how to explain this, like shadow casts inside of object on backface and then inverts from other side at some angles. Seems there are no issues with inbuilt geometry, but even simplest box imported from 3ds max (3ds obj) gives headache. I've attached my 3ds model. And unfortunately this making this software unusable for me. Standard approach is to draw blueprint of walls in acad, refine it in 3d software, import. PVSOL just can't create more or less complicated geometry of roof. And last two screenshots are example of incorrect shading result with imported geometry and inbuilt geometry walls. This looks like minor glitch in import module because native geometry works just fine, and I hope it can be fixed (or it will be fixed), my geometry is really simple here single_model_sliced.3ds

Title: Advice needed – modeling a complex multi-plane roof in PV*SOL (beginner) Hello everyone, I am still fairly new to PV*SOL and would really appreciate some guidance from the more experienced users here. I am currently working on a project with a rather complex roof geometry. The building has several roof planes with different orientations and inclinations, including hipped sections, multiple ridges and valleys, and a few smaller adjoining roof areas (please see the attached aerial view from the PV*SOL map import). The customer's explicit wish is to have the entire roof fully covered with modules – on all available roof surfaces. This is a fixed requirement on their side, so I am not looking for advice on whether it makes sense, only on how to model and realize it cleanly in PV*SOL. My main questions: • What is the best workflow for building this kind of multi-plane roof in the 3D view? Should I model each roof surface separately and then combine them, or is there a more efficient approach? • How do you handle the transitions between hipped/triangular surfaces and the trapezoidal areas so the module placement stays clean? • Are there any tips for keeping the orientations and tilt angles accurate when working from the Google/orthophoto import? • Any general best practices you wish you had known as a beginner with irregular roofs? Since I am just starting out, any advice – even small tips – is genuinely helpful to me. Thank you very much in advance for your time and support. Best regards

Hallo, vielen Dank für die Zusendung der Projektdatei. Wir konnten Ihr Projekt reparieren, indem wir einen neuen Kartenausschnitt eingefügt haben. Die reparierte Projektdatei haben wir Ihnen per E-Mail zugeschickt.

Hallo, vielen Dank für deine Anfrage. Die Kombination von elektrischem Verbraucher, Batteriesystem, Elektrofahrzeug und thermischem System wird ab der Version PV*SOL premium 2027 R1 möglich sein, die wir im November 2026 veröffentlichen.

Hallo liebes PV-Sol Team, an dieser Stelle möchte ich auch nachhaken, ob bzw. bis wann die Funktion einer netzgekoppelten PV-Anlage mit elektrischen Verbrauchern, Elektrofahrzeuge, Batteriesystem und eines thermischen Systems möglich wird. Dies wird in letzter Zeit noch viel mehr angefragt. Vielen Dank für Ihre Rückmeldung. Bisher geht nur Elektroauto ODER thermisches System. VG

Hallo, vielen Dank für Ihre Anfrage. Bitte senden Sie uns die Projektdatei (*.pvprj) und das Bild (den Kartenausschnitt) an hotline@valentin-software.com, dann sehen wir uns das an.

Hallo, ich bearbeite gerade ein Projekt bei dem ich zu Beginn einen Kartenausschnitt auf der Freifläche Platziert habe. Während dem Bearbeiten der PV-Anlage ist der Kartenausschnitt im Hintergrund verschwunden. Wie kann diese wieder korrekt dargestellt werden?

Good Day, my question was actually, what the formula is to calculate the battery DOD at 40%. As per below, it does not reflect what you are getting.

Hello, Thank you for your inquiry. The maximum charge and discharge power of a battery system is limited by either the inverter or the battery storage unit. We will contact the manufacturer, Deye, and ask them to supply the missing SUN-10K-SG02LP1 battery systems. For comparison: The SUN-10K-SG01HP3 battery systems have a maximum charging power of 13 kW and a maximum discharge power of 11 kW. Consequently, the SUN-10K-SG02LP1 battery systems would have a maximum charging power of 16 kW and a maximum discharging power of 11 kW.

Hallo, vielen Dank für deine Nachricht. Rechts neben dem Diagramm "Ertragsprognose mit Verbrauch" findest du den Button "Zur Tabelle wechseln": Die Abregelung am Einspeisepunkt wird in kWh pro Monat ausgegeben:

Dear Sharjeel, Thank you for your inquiry. When creating a new inverter dataset, you typically face the issue of not knowing the inverter's efficiency curve, as it is not published on the datasheet. On May 29, Sungrow updated the SG125CX-P2 and added the new SG125CX-P3. Which inverter are you missing? Please provide the exact model designation or send us a datasheet. We will then contact the manufacturer to request that the information be added or updated.

Dear Mark, Thank you for your message. For lithium iron phosphate batteries, the reference value used to calculate discharge cycles is based on a DoD of 40%. This results in the following factors for the discharge cycles: DoD Value 0.2 2.206563 0.4 1 0.6 0.598166 0.8 0.397315

Dear Mark, Thank you for your inquiry. The house connection, electrical service connection or grid connection is the interface between a building's electrical installation and the power supply grid. It consists of the service entry cable and the service connection box.

What does the "House Connection" mean in the cables layout

Good Day, when calculating Max Charge and Discharge Power in the Battery Setup, do you use the Max Battery Voltage (60Vdc) of the Inverter or the Max Operating Voltage (57.6Vdc) of the Battery multiplied by 220A in this example below?

Thanks, please share with me as soon as you get that formula.
