  1. For us, a fixed (or at least globally adjustable) colour scale for the shade frequency analysis would be very useful. So that e.g. 5% of shading has always the same colour for every roof in every project. As it is right now, 5% or even 10% of module shading might appear as a vibrant green, just because a part of the roof (maybe even with no modules) might be shaded very strongly. Not ideal at all. This, along with an option to export these pictures with one press of a button would be very useful to our workflow. As of right now we have to screengrab each and every roof. Edit: exmple pictu

  2. If anyone else have this problem, I fixed it by exporting the Blender model as an .obj file. Thank you.

  3. To my knowledge, the system operator receives Ausfallvergütung only under special conditions, like when Einspeisevergütung or Direktvermarktung fails. Even then, the operator has to apply for Ausfallvergütung to receive the compensation. So these are very special cases and I don't think it's possible to calculate in PVSol

  5. Hi PVSOL team. I have had a quick play with the 2021 update. Are there any further features soon to arrive? I was really hoping for a few helpful features in the 3D modelling. As 90% of the time all that is required is a rectangular building outline with a line down the centre for a ridge some minor improvements would really help- -Snap to 90 degrees (or a rectangle drawing tool) -Snap to centre point for drawing ridge (or an "auto-ridge" feature) Thanks James

  7. Da ich das gleiche Problem hatte und das hier das erste Google-Ergebnis war: Bei mir lag es daran, dass das in Windows eingestellte Dezimaltrennzeichen gleich dem Symbol für Zifferngruppierung war (bei mir beides "."). Diese sollten natürlich verschieden sein. War also kein Fehler des Programms sondern des Anwenders.

  8. Good afternoon, I think it would be a good idea if Valentin software developers make a wish list in the Forum for the users so they can have a feedback of what is more important and required by the costumers/users and if they are mentioned very often try to include them in the following releases. Here are my wishes ? 1- More stand alone inverter/chargers/components brands, as Victron, Steca, Ingeteam, Solarwatt 2- Bigger area to develop bigger projects 3 - A better relation with 3D software as Sketch-up 4 - The possibility of include some images/pictures or even

  10. Have both projects been through the simulation? For example, has the system with the missing info been paired with an inverter yet, and then simulated? I think you have to configure the system, and then simulate it, to make this comparison.

  12. Hallo Niklas, vielen Dank für die Screenshots. Diese Artefakte sind "negative Schatten" (diese negativen Schatten entstehen häufig an Stellen, an denen sich Schatten überlagern), höchst unschön in der Darstellung und uns auch ein großer Dorn im Auge. Aber die gute Nachricht ist: Auf die Simulation und die Ergebnisse haben sie keinen Einfluss. Beste Grüße, Martin

  14. Hallo Lis, die Wärmepumpenprofile wurden mit GeoT*SOL https://valentin-software.com/en/products/geotsol/ simuliert. Es handelt sich dabei mehr oder weniger um Beispielprofile, da es nicht möglich ist, einen bestimmten Anwendungsfall festzulegen. In PV*SOL ab Version 2021 kann man aber auch eine Luftwärmepumpe im neuen Anlagentyp Thermische Anlage simulieren. Dabei werden die Klimadaten des aktuellen Standorts verwendet. Das Lastprofil "Wohnkomplex" geht auf eine Forschungsarbeit aus der Schweiz zurück ("Warmwasserversorgungen heute; AT Verlag Aarau (Schweiz) 1984"). Von der

  15. Dear dom bez kostów, I used deepl.com to translate your question into English: Unfortunately, I am not sure what the question is. The translation might be misleading. You can view, edit, save and export the circuit diagram, enter all the electrical devices you want, dimension the cables and so on, no problem. You can do so on the plan and the cabling pages: If this doesn't answer you question, please don't hesitate to ask again. Kind regards, Martin

  17. Hello, I have a general technical question; is it ok to connect 2 strings with different modules number to one MPPT (18 and 19 for example when using the polystring feature in PV sol). I've read on some forums that there are losses due the voltage mismatch and the MPPT tracks the string with the lowest performance; but is it really a red line for PV designers or it's just not preferable and I can do it only when necessary? Thanks in advance Karam

  18. Hi Burak, the 0,4 ct/kWh is the so called "Management Prämie" that shall compensate for the extra cost that a PV system owner has when he or she is opting for the "Direktvermarktung" In the numbers published by the "Bundesnetzagentur" those 0,4 ct/kWh are already included: https://www.bundesnetzagentur.de/SharedDocs/Downloads/DE/Sachgebiete/Energie/Unternehmen_Institutionen/ErneuerbareEnergien/ZahlenDatenInformationen/PV_Datenmeldungen/DegressionsVergSaetze_11-01_21.html They provide an Excel file that you can download, and in there there is a sheet called "Beispiele".

  19. Hi Ricardo, the active power will be capped. The output power clipping is based on the apparent power, say S_max. With cos φ = 1, the system will not produce reactive power, so active power equals apparent power, and the maximum power output is P_max = S_max. When the cos φ is smaller than 1, the maximum active power output will be reduced by this factor (while the maximum apparent output power remains the same), since P_max = S_max * cos φ. Hope that helps, kind regards, Martin

  20. Dear Ricardo, unfortunately we don't have a detailed explanation of each item of the energy balance yet. But this is a good suggestion, we will put it on our request list for extending the help pages. The "Down-regulation on account of the max. AC Power/cos phi" takes place when the AC power of the PV system is higher than the maximum AC output of the inverter. In this case the inverter has to regulate the output power down to the maximum permissible power (by choosing another poit on the IV characteristics if the PV field on the DC side). The cos phi will reduce the maximum permissi

  22. Hi Sondre207, I must admit I missed your question. Sorry about that. Within the graphical allocation (2D) this is possible: Set installation type to Mounted - roof Uncheck Roof parallel and set a different module orientation Change the module inclination to 0° Change the row distance from 1m back to 0.005m to get rid of the default row distance In 3D you can achieve a similar effect by using module mounting: which results into this configuration: The problem is you cannot get rid of the mounting system as far as I'm concerned..

  23. Hallo, ich würde gern ein Bürogebäude mit Flachdach und dessen Aufbauten mit PV-Modulen bestücken. Leider funktioniert dies nicht so leicht wie ich dachte. Die Treppenhäuser habe ich mittels Brandwände auf dem Flachdach als Körper platziert. Leider bekomme ich auf diesen Körpern dann keine Module platziert, sondern - wenn ich diese aktiviere - nur an den Wänden. Könntet ihr mir bitte weiterhelfen, besten Dank. Hat sich erledigt - die Erstellung mittels Polygon und extrudieren war die Antwort - trotzdem danke.

  27. Hi Ricardo, ok, this is strange. Usually the user id is not renewed or reset except when you install it on a new device. One quick work around for you would be to copy the module with hidden user id when you open the project file where it is contained. This would make it available for you in other projects as well. I'll ask you to send me some files via private message in order to analyse the problem. Kind regards, Martin

  29. Hi Ricardo, thanks for the project. These are two different module types and if you select all of them, the generator power is calculated from the total number of modules and the lower of the two module powers. This only affects the display, however, the correct generator power will be displayed during interconnection and after exiting 3D. But I will set the issue on our list as it can easily confuse. Thanks for reporting! Kind regards, Martin

  30. Hi Robert, the translation from Polish to English might be a bit rough, but from what I understand you are wondering about the DC cabling visualisation of the inverters with more than one PV module, is that right? As I don't have the project file, I can only refer to the screenshots. The module numbers reveal that there is always just one PV module per string. A string has a + and - minus symbol at its ends, from where the cabling goes to the inverter. So as far as I can see the visualisation is also correct? Sorry if I am getting the question wrong... Kind regards, Martin

  33. Hallo Julian, wenn das Programm meldet, dass fehlende Informationen nicht ermittelt werden konnten, handelt es sich in aller Regel um das Land des Standorts. In diesem Fall konnte es den Standort nicht ermitteln, da der Längengrad das falsche Vorzeichen hatte. Also streng genommen ist es ja das richtige Vorzeichen, nur muss man es für den Import in Meteosyn anders herum eingeben. So klappt's: Tzoukri 39.1334,-20.5429,40,-2,-30 ... Viele Grüße, Martin

  35. When clicking on a Module Array in the list on the left-hand side of the screen, it automatically activates and therefore “jumps” to the selected array. This is unlike the buildings, which just get highlighted when clicking on them. I much prefer the later behaviour and would appreciate if it were the same for the Module Arrays. It would make locating & renaming them much faster & easier.

  40. Dear Natheera, the climate data we use in PV*SOL is from Meteonorm, that is correct. The Meteonorm climate data are based on various sources of radiation measurements (ground stations, satellite) , with different time ranges (e.g. 1961 - 1990 or 1991 - 2010 and so on). The availability of climate dataset source varies from location to location. You can find more on that topic here in the manual of Meteonorm in Chapter 3.1: https://meteonorm.com/assets/downloads/mn73_software.pdf This information refers to a another type of product by Meteonorm, historical time series with one

  41. Hi K24, as Vishnu pointed out, the activation of minute values is most of all important if you have sizing factors of above 115 %, or if you have battery systems or electrical appliances that are involved. If your DC/AC ratio is about 1, and you just want to analyse the feed in, you might be well off with hourly values. But I would always recommend to compare the results at least once. Just simulate your PV system with hourly values, save the results somewehre, and then simulate the same system with one-minute values. Then you'll directly see the differences for your specific case.

  43. Great ideas all of them, specially the first 3. If I may add another, I'd like to not only have input to enter the exact line length, but also to enter the line relative angle, a bit like what can be done with buildings: That would be very helpful when you need to draw complex buildings and and make sure modules on different roofs are oriented similarly for configuration in the same MPPT. Please see below an example of a rather poor attempt I was working on recently: Keep up the good work and thanks for your timely replies!

  44. Martin, I was genuinely thinking it was my fault the data was not being adopted, that I had done something wrong. It never crossed my mind this could be the intended behaviour by design. The logical approach (at least to me) would be to use 3D to take precise length measures and then adopt them into the 2D design. I always assumed this was the case. As it is it makes absolutely no sense at all, I can't understand why was this module designed like this, and I see it's not just me. What you're saying is that all of the trouble of designing combiner b

  45. hey Alberto, I can think of only one reason for this. As you mentioned that you've used two difference modules, there is a chance that "Anti Reflection Coating" is different for the two modules. This is just my assumption, may be there is a better explanation the PV Sol team can provide. Also the "orientation and inclination of module surface" is different for the modules. Is the inclination different for both the cases?. If yes, this is also a reason for different reflection losses. Cheers..!!

  46. Hi Kamal, these kind of bends occur when you have unequal number of modules in your strings. The curve section from 0V to the point where the bend occurs is where the two strings both deliver a current for the given voltage. After the bend, up to the open circuit voltage of the longer string, only the longer string (with 21 modules) can deliver current, the other string is not contributing anymore. Kind regards, Martin

  48. 1. More control when drawing lines: snap to 10cm or input to drive line length 2. Snap to mid point of line - the ridge of a roof is almost always in the middle 3. ctrl+Z to undo 4. better control when rotating the camera position 5. Higher resolution on panels when zoomed out 6. Default project image zoomed out enough to show whole array Keep up the good work PVSOL team.

  50. Hi Tom, thank you for your question. The Accrued Cashflow minus the pending loans would be your normal cashflow minus all the loan repayments and interests that you still have to pay in future. So, for example: Here I defined a 10 year loan over some 4320 $ with 2 % interest rate and the first 2 years without repayment. If you sum up all loan repayments and interests until year 10, you'll get -5254.16 $. To calculate the Accrued Cashflow minus pending loans for the first year, you'll take the normal cashflow (701.79 $) and subtract the 5254.16 $, but, as you consider the en
