  1. 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.

  2. 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

  3. Hello everyone, please share your best image/design created with PV Sol. Why? - To show and explain the best ways to create visually attractive solar systems. This is mine created with amazing PV Sol; A new-build housing development in the UK - instead of roofing with attractive expensive Cornish slate, the contractor wants to reduce their material costs by installing in-roof panels and experiment with how 'green' they could get. We were able show the contractor thier project in PV Sol by;Importing the site plan, altering the orientation and referencing elevation plans to recreate th

  4. 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

  5. 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

  7. 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

  9. 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

  12. Dear Remu, there are a whole lot of reasons why simulation results differ between PVGIS and PV*SOL. 1. The climate data used is different. Most of all the irradiation data, which has the strongest influence on the results. The standard in PV*SOL are climate data from Meteonorm, while PVGIS uses its own compiled climate data. See these forum threads here: 2. The simulation models (and even the simulation approaches) are completely different. We follow a time-step based approach (in one-hour or one-minute intervals) that is simulating very accurately the irradiatio

  13. 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

  14. Hi Karam, no, I would not say that connecting strings with different module numbers is a red line in general. Why not try it out in PV*SOL directly? We calculate the losses due to string mismatch with great accuracy, so you can just see how much energy you loose in you PV system and see for yourself if you can accept these losses. You can also see the resulting IV characteristics of your parallel strings in the results page (under Simulation -> Diagram Editor -> Type of Diaram: Characteristics) Kind regards, Martin

  16. Dear Bernard, unfortunately this is not directly possible, no. But you could do the following: copy the data of the horizon line table to the clipboard, paste it in Excel subtract 180 from the azimuth values copy both azimuth and height values to a text file use space as a value separator save the file as *.hor Of course this would only include the horizon line and no near objects. May I ask the use case for the hor-export function? Perhaps we should consider implementing it in the future. Thanks, Martin

  17. Dear Bernard, thank you for your interesting question. The hor files only contain the horizon line value pairs. That is, those values only apply for shading objects that are far away from your pv system (=horizon or very distant houses or the like). The horizon line always has a transmittance of 0%. For near shading objects like trees you should not use hor files, but real 3D objects instead. In the 3D planning environment in PV*SOL premium you can choose from several objects like chimneys, walls and said trees. Those trees can have custom transmission factors.

  19. 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

While answering your question and after some tinkering with some bifacial modules: Here are three projects with the same location and inverters and reasonably comparable modules (I attached the projects too): 1. South orientation, non bifacial 2. South orientation (same as first), bifacial 3. East-west orientation (90° inclination), bifacial Where bifacial modules clearly shine is the third project, bifacial east-west 90 degree inclination. Naturally this is one of the most interesting of applications: Agricultural PV systems, perfect due

  26. 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

  27. Hi Ragy, the reason for the downregulation losses due to the MPP voltage range is that in winter time the modules are causing a shade on each other: You can see the module-specfic shading losses in the carpet plots very well: The modules are connected 11 in parallel by 17 in series, so the resulting module array characteristics look like this: As you can see there is a pronounced drop of current in the upper voltage range above 400V. In the power-voltage plot it looks like this: So the maximum power point at this specific point in time (01.01. at 1

  30. 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

  31. 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.

  34. Hi everyone & Valentin, we're creating an orientation and pitch chart to show others clearly the kind of performances to expect. Like a compass - difference in Orientation axis follows around the chart, and difference in pitch runs from the centre to the circumference in smaller to larger circles (0 degrees to 80 degrees pitch). So the first circle from the centre represents 10 degrees pitch, the second circle from the centre represents 20 degrees pitch and so on. It's quite smart and will hopefully give clarity to others than Northern facing systems still produce an acceptable level

  37. As it's Friday I thought it would be nice to share an interesting PVSOL challenge and 2 solutions. I am working on a curved building with a curved roof. solution 1: modelled in SketchUp with measured flat sections on roof to place panels - this looks pretty but took ages to get curved roof to meet curved walls. Solution 2: built in PVSOL 3D design, multiple 2m wide single pitch buildings (lots of trigonometry) - this will be more flexible for small adjustments in roof pitch.

Für die anderen Leser fasse ich mal die Anlage-Konfiguration zusammen: In diesem Fall sind 14 Module mit SolarEdge P370 Powert-Optimizern auf einer Dachfläche (Nord-Ost) in Reihe geschaltet mit 10 Modulen auf der gegenüberliegenden Dachfläche (Süd-West), die ebenfalls mit P370 ausgestattet sind. Der SolarEdge Wechselrichter SE7K, an den die Module angeschlossen sind, hat eine feste MPP-Spannung von 750 V. Was in diesem Fall passiert, kann man sich anhand der Kennlinien in den Ergebnissen ganz gut visualisieren. Die Aufzeichnung

  41. Hi João, No, sorry. But you could simulate the 3D environment without tracking, save the shading losses from the results and enter them as a shading percentage of your 2D simulation with tracking system. This will only cover the shading by far objects (homogeneous shading), however. A detailed shading analysis with mutual shading of the trackers for example, is not possible. But if the tracking systems have sufficient distance from each other, this won't be problematic. Hope that helps, kind regards, Martin

  42. Hallo Tim, wir hinterlegen keine Preise für Module oder Batteriespeicher oder andere Komponenten in der Datenbank. Grund dafür ist, dass jeder Projektierer oder Anlagenplaner mit Sicherheit unterschiedliche Preise bekommt, je nachdem, welche Volumen er bei welchem Großhändler abfragt, wo auf der Welt er sich befindet und wie der Markt dort gerade läuft. Die Stückkosten oder Gesamtkosten für die Anlage sind also individuell vom Planer in PV*SOL einzutragen, entweder als Einzelposten oder pauschal in €/kWp. Beste Grüße, Martin

  45. Hi Daniel, this value refers to the current energy mix in the country where you design your PV system. In Germany, for example, we have an energy mix that produced ~ 530 g CO2 per kWh in 2016. This value is used to calculate the CO2 emissions that were avoided thanks to your PV system. Kind regards, Martin

  46. Hello James, first of all, we are very happy that they like this feature. Answer 1) Of course you are absolutely right! Since the Boundingboxes of imported 3D-models are rather rough, it can be difficult to push the models together. I have already added the feature for Release 2.

  47. Dear jerryg, edit: See updated information in the post below thanks a lot for your question. If you select the power optimizer on inverter level, this option is valid for all modules that are connected to the inverter. So, the power optimization is done on module level, of course, not on inverter level. If you're asking to have some modules on a MPP with power optimizers and others without, that is not possible. Also at the moment it is not possible to have uneven strings or modules with different slope and orientation on a single MPP. But right now we are working on this

  49. The program needs a relative constant and stable internet connection. If this is not guaranteed, then the program aborts the download of data. Alternatively you can also try to download the latest program version from the download section of our webpage: http://www.valentin-software.com/en/downloads/products Please execute the downloaded setup file. The old program version doesn't need to be uninstalled.
