  1. Good Morning, Quick question about slightly more complex building (such as the attached). I am struggling to design anything like this with my latest PV SOL premium 3D. Is there a way to fairly simply do this by any chance? (This building is also available in 3D on Google map - do you know a way to maybe import that 3D model into PV SOL?) Many Thanks Steven

    Absturz PV-SOL

    Hallo, diese Datei ist durch 'Abspecken' einer funktionierenden Planung entstanden (Mudule und Flächen gelöscht). Wenn ich die Datei bearbeiten will (3d Planung) stürzt das Program (V1.6) ab. Gruß Wolfgang Lichwr-GgeS-14M-Kostal.pvprj
  3. Hello, I want to ask how to fix this problem with importing model from sketchup, because when I import model, there are some bugs, like imports not full surface
  4. Hello Valentin Team, I`ve created 3D project with bifacial modules (east/west) I don`t know if i do something wrong or there is a problem in aplication but in "Calculation": PV Generator Energy (AC grid) probably calculates energy only for one side. I`v done some tests and facade configuration heading to west producing the same amount of energy as bifacial setup heading to east/west. Calculation works correctly in 2D. Bifacial and facade projects included in attachment. Niemierzyno_1.pvprj Niemierzyno_1_proba_usun.pvprj Niemierzyno2d.pdf

    Horizon line

    Hi, I am planning to order student version of your software for a research, so I started researching what could be done in PVSOL. Could you do some short video or a detailed written explanation on making horizon line in 3D?
  6. Working closlely with building companies they often want a 3D model of the house that they are building. When will it be possible to export the 3d building from PV Sol? (so that you can 3D print the model amongst other things)
  7. Some of Valentin's PVSOL Premium potential customers might have, as I did, decided to buy the software based on 3D modeling and shading simulation capabilities. Several anecdotal evidences of this capability can be found on this forum, and on promotion materials spread across several media by Valentin Software sales team. Let me give some examples below... Above - PVSOL Online Shop suggests drone usage for photogrammetry Above - Youtube tutorial suggesting the use of photogrammetry software for 3D import (Pix4D) Above: Feature advertised online since 2017, note the mention to "3D objects created with photos taken from a drone" I guess these examples should be enough to prove the spin over 3D photogrammetry and real life 3D models import into PVSOL. Most people most probably will do the same as we did, download the software and try it out with simple small examples, and it does work, how nice... we then decide to buy the software. Unfortunately it's only when starting to use it for real, with real projects, real data, real photogrammetry, that the trouble starts... errr... ok... let's go smaller then... decimate 3D model and retry... oops... there is a limit of ONLY 500.000 vertices! Anyone with the thinnest experience in photogrammetry knows 500k vertices is nothing, any model with such a low count of vertices is either a single building alone with very little detail and very decimated, or the scene is in terribly low quality with lots of 3D defects. This 500k vertices limit renders the 3D photogrammetry almost useless. In order to work with photogrammetry 3D models one has to decimate the model to a number of vertices really below the 500k vertices limit, because as reported in this other thread (without answer for weeks now) the vertices count is wrong and includes some own PVSOL vertices as overhead, limiting even further the model quality. We have no choice but to comply with the previously unmentioned limits, and we decimate the model further, making the 3D almost unrecognizable, and voila it finally loads and we can start designing the PV system believing all is well now, apart from the 3D miserable quality: This illusion ends as soon as we press the "Start shading frequency" button with the option to show shading percentages on the modules. With the example above, with only 320 modules, the application crashes with an "out-of-memory error": Now this is very strange because this is a 16GB machine and memory usage by PVSOL process never went above 1.4GB on all of the tests we did, so there is a nasty bug here. Valentin official answer is to just say we ran out of memory (despite proof we did not), and telling me "We would use the planning mode with map section.", yes really! So we are working with a 3D model decimated already to just a few hundred vertices, and still PVSOL can't cope with it. Astonishing! We did not give up, and went to the extent of DELETING part of the 3D model objects, parts that would not interfere with shading on the modules, and decimated even further. The result was an .obj file with just 82.034 vertices, that’s 16% of what PVSOL claims to be able to handle, and guess what... it still crashes and can't simulate shading. Conclusion: Don't be fooled by Valentin Software claims over the use of 3D import of photogrammetry models, it's nothing but a toy for micro systems, it's not for professional use. Hope this narrative is useful to anyone considering buying PVSOL Premium based on 3D photogrammetry imports. PS: I have found PVSOL capabilities in regards to computation to be flawless thus far, if you don't mind a miserable 3D component, it's worth it. The 3D module however is just lame. PPS: The worst part on this is that Valentin Software refuses to admit it has a memory management bug, and provides no real assistance nor solution apart from dropping 3D import.
  8. Hi, I am exported Sketchup model and imported to PVsol. but error is showing like this.How I have to proceed? Regrads, Abhilash
  9. Hallo Valentin-Team, ich habe Probleme mein Projekt durchkalkulieren zu lassen, da man dafür ja die Abschattungssimulation benötigt. Wenn ich diese Ausführen will, stürzt das Programm ab. Also komme ich wieder zur Frage zurück, welche ich bereits in einem anderen Thread gestellt hatte, die aber leider noch nicht beantwortet wurde: Welche 3D-Bild Eigenschaften soll man beim Exportieren des 3D-Bildes einstellen, damit PVSol richtig funktioniert? Dank im voraus. Anton
  10. Hallo zusammen, Ist es möglich, mehrere Gebäude mit unterschiedlicher Ausrichtung und Abständen zueinander, z. B. ein Quartier, miteinander zu koppeln? Beispiel: Ich habe 5 Gebäude mit verschiedenen Ausrichtungen (Ost, Süd-Ost, Süd, Süd-West und West) in unterschiedlicher Höhe und Abständen zueinander. Ist es möglich die PV Anlagen auf jedem Dach miteinander zu koppeln bzw. Batteriespeicher einzubinden und das Gesamtsystem zu koppeln? Danke. Gruß Pascal

    PV SOL 3D import

    Good day, I am using PVSOL premium 2019 (R13), is their a possibility that I could import a 3d model to the simulation? if yes, how can it be done and what are the acceptable file formats? thank you in advance for your kind assistance.
  12. Hallo, ich wollte fragen, ob es irgendwie möglich ist, die Module, die nach Westen ausgerichtet sind, mit den Modulen zu verschalten, die nach Osten ausgerichtet sind. Wenn man die Fläche jetzt markiert und auf automatisch verschalten geht, funktioniert das nicht. Danke für eure Hilfe! LG, Christina

    Hallo Leute. Bin blutiger PVSol-Anfänger: ich schaffe es bei der 3D-Planung nicht die von mir vorgegebene Dachneigung einzugeben. Ich stelle ein: Neigung ändert Höhe. Was passiert: Höhe wird nicht verändert und auf vorherige Dachneigung zurückgestellt. Kann mir jemand den Vorgang erläutern? Ich finde keine vernünftige oder nachvollziehbare Erklärung... Vielen DAnk für schnelle Hilfe...
  14. When i start a new project i cannot pass the 3D design phase, as soon as i open the window it pops up a error saying "Fehler beim Zeichnen des Prims" and after pressing ok it closes. How can i fix this error?
  15. Hi, When simulating a particular project and reading the EB, I can see that the module independent shading, which I normally assume to be due to the horizon (far) shading is just below 6%. Looking to the module dependent shading, I can see that this is at around 16%. Two aspects are interesting when it comes to this: The total shading loss over the year, presented in the summary, is 23.2%. Removing the horizon from the 3D model reduces the module dependent shading almost entirely. Knowing how the help file defines independent and dependent shading, I am a little confused by these two contradicting aspects. Regarding (1), what is the logic inferred here? Shouldn't the loss presented in module dependent shading be a share of the incoming radiation converted at STC into a certain available energy quantity? How can the relative loss before and after STC conversion be added together, when the loss on module level would be much smaller if corrected for the conversion efficiency? Regarding (2), what is the relation between horizon (module independent) shading and near (module dependent) shading? It is reasonable to expect that removing the horizon would remove the module independent shading loss. However, as it seems, it actually also removes the module specific shading. How can this be? I would expect these two losses to be distinguishable and non-interactive. Appreciate any explanation, as I haven't been able to find an elaborate explanation elsewhere.
  16. Hi, Whenever I try to use the 3D scene in PVsol 2018 (R4) it begins to load the scene with a progress bar, but upon completion the program freezes. I have tried uninstalling the GPU and installing newest drivers, uninstalling and re-installing PVsol, opening files in previous versions of PVsol, aso. Nothing seems to work. Do you know what might be causing this or any suitable solutions?
  17. Hallo Zusammen, ich möchte gerne eine PV-Anlage über mehrere Reihen-Flachdächer simulieren. Die einzelnen Häuser haben jedoch verschiedene Höhen, sodass ich jeweils ein Gebäude an das andere ansetzen möchte.. Nun habe ich aber Probleme damit, diese "passgenau" an einander zusetzen. Gibt es eine Möglichkeit die Häuserwände über eine Funktion logisch miteinander zu verknüpfen, sodass die Wände der verschiedenen Gebäude ( mit gleichen Maßen) an einander gesetzt werden? Wenn ich es über die X und Y Koordinaten versuche, kommt es immer zu kleineren Ungenauigkeiten. Vielen Dank im Voraus und freundliche Grüße, Alex
  18. Hello, I am trying to design a 3D PV system on a flat roof of a building. However, there is a tall BTS tower just next to the building. I have tried to model that lattice tower in 3D visualization but I could not succeed. The best I could do is to replace a solid chimney and change the texture of it. So it looks like a lattice tower. However, I think the PV system performance may change according to the shading from a lattice or solid tower. Is it possible to model a lattice tower in PV*SOL? Best Regards,

  23. Hello, I recently purchased the PV-SOL Premium and I can't run simulations or reports because on the bottom of the page I read the error "First, please define a valid system in the 3D visualization". No matter what type of system I select I can't run any report in 3D. What do I need to do? Thanks, Tommaso
