  1. 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.
  2. I have been struggling to import load profiles into Premium edition. My task is to import Half Hourly usage data for a site into PVSol, then I can run a simulation to predict the Exported energy and onsite usage, important to show the business case for a local Power Purchase Agreement. My problem is that no matter what format I try (text or CSV in every combination that Excel can output), I cannot get the data to load into the 'Import Load Profiles' section of the 'Consumption' page. The Error message is 'konvertierungsfehler in datensatz in zeile 1', or 'conversion errors in data in line 1' translated. I have even tried to word wrap the text file to try to get it into a single column then save it without luck I have tried formatting the column to ensure there are 2 decimal places, so it mimics the 'number format file' drop down list (####.##) exactly, but no. I believe it is a format issue, but I really cannot work out what it is. I have included a couple of the files I have tried on this posting. Can anyone help?

  3. Hallo, ich möchte DWD Wetterdaten importieren. Die Option gibt es im MeteoSyn. Hier ist als Dateiformat lediglich xlm vorgesehen. Auf der Website des DWD gibt es keine Optionen verschiedene Dateiformate auszuwählen. Es werden lediglich DAT dateien ausgegeben. Gibt es ein Convertierungstool das aus den DWD dat dateien xlm Dateien generiert werden? Werden die Wetterdaten im Meteonorm convertiert? Im PVSol Handbuch finde ich keine genaueren informationen. Vielen Dank für Eure Rückmeldung

    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.
  5. Hello, Is there a way I can import the consumption load profile in .slg file from the older version 2019 R14 to this new version (2020 R2)? Hope someone get answer my query :)
  6. Hi, I have troubles with creating and importing a TMY-file that has been provided. I just dont get the creating and importing .dat files to work. Assistance and help in this matter would be highly appriciated ? The file I would like to have as a .dat file that can be imported is attached. BR Daniel TMY.csv
  7. Hello, I'm Leon and we are working on the project that involves 3d scanning with a drone. We've made 2 flight attempts so far and got pretty good scans but the problem is that STL files are so huge, 350+mb at least. What steps can be taken to reduce the size of 3D scans without significant loss of quality? We've never faced a problem like this before - in fact, all our efforts were aimed at improving the quality of 3d scans. Would you mind enlightening me? Does changing the file format reduce its size? Our software can export STL, OBJ and other formats (https://www.artec3d.com/3d-software/artec-studio#compare-studios). Is there any 3D application that can decrease the quality of 3D model textures? We may try to make another flight and "split" a 3D scan into several parts, but I'm not sure it will work. Any advice would be greatly appreciated Regards.
  8. Hello, I am new with the software. I have the load profile of 337 days in 15 minutes interval and I want to import these data into PV*Sol, so I can calculate the dimensioning of my pv system. The objective is 100% self-supply with the minimum injection. The pv system is grid connected. As I have the load profile, I chose "Grid connected PV System with Electrical Appliances". I tried to add the data in "Consumption-->New Appliance-->Impoart and load Load Profile-->Import new load profile" but it only accepts .txt files, so I copied my data array in excel but I receive the prompt "Number of data records is wrong". How can I work with the load profile data that I have collect over the last past year? Please help. Thanks Gustavo
  9. Hallo zusammen, ich habe in diesem Forum bereits ähnliche Fragen gefunden, leider dann doch keine, die meine beantworten. Zunächst finde ich tatsächlich nirgends die Import-Option von Lastgängen, oder ist damit tatsächlich der Einfügen-Button gemeint, der im Fenster Parameter vom WW-Verbraucher ist? Wenn ja, lege ich da einfach die txt Datei meiner Minutenwerte in meine Zwischenablage? Meine eigentliche Frage ist aber eigentlich noch eine ganz andere. Ich habe einen Lastgang, der die Minutenwerte der Wärmeabnahme sowohl für WW als auch für Heizung abbildet. Die Solarkollektoren sollen Wärme in ein Nahwärmenetz speisen, von dem die Haushalte eben auch direkt beides abnehmen. Ich finde allerdings in T*Sol dafür keine geeignete Anlagendefinition. Ich könnte natürlich meine gesamte Wärmeabnahme über Heizwärme definieren und WW-Abnahme auf Null setzen. Allerdings finde ich bei bei Heizung keine Option des Imports eines Lastprofils. Ich hoffe ich konnte meine Frage verständlich ausdrücken. Vielen Dank für die Hilfe im Voraus. Beste Grüße, David
  10. Is it possible to import horizon files into PV*SOL or T*SOL? Which tools are compatible?
