  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

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.

  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

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. 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

  24. 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

  28. Hi Jordn, this is a very interesting project you are working on there! Thank you for sharing this. In general, the climate data used to simulate the PV system have the strongest influence on the symmetry of the results. Other influences can come from the models used to calculate the irradiance on the tilted plane and so forth, the synchronity of the sun's coordinates with the climate data and the like. I just checked this for some locations and climate data sources, and compared the orientations 90° (East) and 270° (West) with 180° (South), all at 30° inclination. Berlin

  34. Dear Bulent, thank you for your question. In PV*SOL, we use climate data from the well-known climate data specialist Meteonorm, see here: https://help.valentin-software.com/pvsol/2019/calculation/irradiation/climate-data/ PVsyst also uses Meteonorm, so in terms of irradiation data there shouldn't be any difference between PV*SOL and PVsyst. Do you have an example project where we can see PVsyst and PV*SOL energy yields side by side? Often the differences in the energy yield come from the models that are used to calculate the irradiance on the tilted plane of the PV modules.

  35. 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

  38. Hi, When I have an AutoCAD drawing of a building or area as seen from above (top view), I usually import it via the "Coverable object - Map section" under the 3D Design tab. The problem then is to create buildings which have the exact length, width and orientation as those shown in the drawing. What I normally do is to "Sketch a 3D Polygon" which coincides with the drawing as much as possible and then stretch the sides until they are as close to the real dimensions as possible. However, if for example the building's length is 25 m, often I will end up with either 24,976 or 25,

  42. Hello Yvar, welcome to our forum! PV*SOL simulates on substring level of the PV modules so that the losses due to active bypass diodes are taken into account. Each substring will be checked whether there is a shadow in this substring or not. If there is a shadow, the bypass diode is active (curve 2 & curve 3), otherwise not. PV*SOL assumes from this that the shaded substring are never completely in shadow, but that there is always diffused radiation on the shaded parts (curve 2). There is therefore a I-V-curve with lower current for these cells as well. If the resultant MPP
