Dear and, this is feature that was only recently introduced, in PV*SOL premium 2020 R4. If you are using an older version, consider updating it, then it should work. Thanks and kind regards, Martin

Dear Sander, are you trying to add the module in PV*SOL or on the manufacturer website? Is there any error message that pops up? Could you provide a screenshot perhaps? If you want, you can send it via private message. Thanks in advance, kind regards, Martin

Dear Ricardo, a movement of the underlying map/image is not possible, I am afraid. And unfortunately there is no way to copy objects from one project to another, neither. At least not the simple way. A possible way exists, but this is a hacky workaround. It is unofficial and we don't do support for projects that are broken due to this hack. But if you want to try, you can do the following: Save the first project twice (one for safety, and one you will modify) Create a new project where you select the new map section as desired (with brown surface above). Try to select it in the same zoom level and x/y dimensions Save the new project with a new name (e.g. "new map section.pvprj") Close PV*SOL Use a zip program like 7zip to unzip the file "new map section.pvprj" Amongst the unzipped files, you will find one "MapExtract.png" and inside the folder Visu3D you'll find "SelfCreatedTexture150.png" Copy these two images to another place, these are the new map sections for your old project Unzip also the old project (the one you created for modification from step 1) replace the files "MapExtract.png" and "SelfCreatedTexture150.png" with the ones you copied elsewhere (from step 7) Select all files in that folder and zip them Change the file extension from *.zip to *.pvprj Open the modified project, and you can see that the map section was replaced. Now you would need to adjust the location of the building, but that is possible from within the software. Hope that helps, and sorry if we can only provide this dirty workaround at the moment. Best wishes for you home office experience as well! Kind regards, Martin

Hi Joey, this is label appears when you have a single-phase inverter on a 3-phase grid. If you have two single-phase inverters, two labels appear: If you have three single-phase inverters (or any number of 3-phase inverters), nothing appears, as the phases can be distributed evenly. If you have a number of inverters that is not divisible by 3, the phase configuration appears: Hope that helps, kind regards, Martin

yes, at the moment the map import is limited to 800m width and height. You can see if you are within these limits when you choose your map section: If the numbers are red, it is not possible to select the map section because the dimensions are too large. If you need to simulate bigger PV plants, I would recommend to use the normal "2D" way of planning. Kind regards, Martin

Hi Rodrigo, a solar park can be easily designed with the module mounting feature in the 3D environment. There you define the mounting system, which modules to take, row distance etc: If you need further help, please don't hesitate to ask. Kind regards, Martin

Hi Jordn, there are some predefined module textures that are available in the 3D mode of PV*SOL. Go to the tab "Module Coverage" and right click on the modules, then choose "Change texture". There you can choose various cell textures and also the color of the backsheet and the framing. Let me know if this is sufficient for you. There is also another way to change the module texture, but this involves some tricky file handling and is an unofficial (and unsupported) approach. But yes, it is possible to integrate the texture you posted: Kind regards, Martin

Hallo DDF, man kann wählen, ob man alle Angaben in brutto oder netto eingibt: Man wählt das also einmal, und muss dann alle Eingaben entsprechend konsistent halten. Beste Grüße, Martin

Hallo Anton, ja, diese Funktion wird in unserer Simulation generell so abgebildet. Es wird immer zwischen der minimalen und der maximalen MPP-Spannung der globale MPP gesucht. Wir gehen davon aus, dass das zu den grundlegenden Funktionen eines Wechselrichters gehört (also dass das alle können). Anders sieht es natürlich bei Festspannungs-Wechselrichtern aus. Beste Grüße, Martin

Hallo Julian, um PV-Anlagen mit elektrischen Verbrauchern zu rechnen, musst du zunächst die Anlagenart umstellen: Und dann ist es mit dem Eigenverbrauch so, dass er sich aus dem Zusammenspiel zwischen Energieproduktion der PV-Anlage und dem Energieverbrauch der Verbraucher ergibt. Man kann ihn daher nicht einstellen, so dass er beispielsweise 25% beträgt. Wenn die PV-Anlage im Jahr z.B. 10000 kWh produziert, und man einen Verbrauch von 2500 kWh hat, wäre das ja bilanziell übers Jahr gesehen ein Verbrauchsanteil von 25%. Es ist aber nicht gesagt, dass die PV-Anlage zu jeder Zeit die Last decken kann. Die Gleichzeitigkeit und die Leistungs-Profile von PV und Last sind hierbei ausschlaggebend. Auch der Zeitschritt der Simulation hat einen erheblichen Einfluss auf den Eigenverbrauch. Am besten wählst du mal ein paar Lastprofile aus, mal in 1min, mal 15min und mal 1h-Auflösung und variierst den Jahres-Energieverbrauch und simulierst das dann. Du wirst sehen, wie sich in den Ergebnissen der Eigenverbrauch ändert. Wenn du mehr Unterstützung brauchst, sag Bescheid. Beste Grüße, Martin

Dear Aurora, could you please send us the project file that you used to produce the report? You can send it by private message. Kind regards, Martin

Dear Supportcenter EWS, as Marcel pointed out, we are aware of the fact that this feature is highly demanded by our customers. And be sure that we are not holding it back artificially. The undo function is quasi-impossible to implement in the existing code of the 3D environment. It would make it necessary to restructure the whole code from scratch. And since we are working on a completely new version of the 3D environment, it wouldn't make sense to rebuild the old version from scratch. We hope this is comprehensible. As a workaround against the worst cases of work loss we introduced the autosave feature some versions ago. With this you can jump back to earlier versions of your project if something unexcepted or undesired happened to your project. I know this isn't a full replacement for the undo function, but at least it avoids the loss of data or long hours of work. I am sorry to hear that. While we are always trying to produce the best simulation and planning software that is possible with our resources, we can't avoid that single customers aren't satisfied. If you want to stop using PV*SOL you can just refrain from extending your maintanance contract the next time. Kind regards, Martin

Dear Joao, you could try to follow the advice here in order to resolve this problem: Hope that will resolve the problem for you. Kind regards, Martin

Hi Remu, you can use the Enphase inverters in the automatic or manual configuration like any other inverter as well. Here in my example I have 44 modules on the roof, so I use 44 Enphase inverters: You can also select all Enphase inverters using the link under "Suggest Configuration", and let PV*SOL search for a valid configuration by clicking on the arrow. Regarding the DC and AC power values of the Enphase IQ7-60. Its values are correct in the database: You will have to allow for sizing factors (DC power / AC power) of above 140%. You can do so by clicking on "Configuration Limits" and then set the upper limit to 150 for example: Hope that helps, kind regards, Martin

Hi Remu, thank you for reporting this error. I will forward it to our database team at database@valentin-software.com. If you find any errors concerning the database entries in the future, you can also report it to them directly. Kind regards, Martin

Dear Luis, it seems that there are problems with your graphics card. "Fehler im DirectX-Device" (Error in the DirectX device) indicates that your graphic card has produced has error when executing DirectX functionality. "Fehler beim Zeichnen des Objekts" (Error when drawing the object) is a consecutive error, I'd say. Please check if you have installed the latest drivers for your graphic card. Also try to run dxdiag, please. Hit the "Windows" key, type "dxdiag", wait for the loading bar to finish and the click "Save All Information". You can send the file via private message. Hope that helps, kind regards, Martin

Hi Remu, can you elaborate where your difficulties are? Kind regards, Martin

Dear Remu, sorry for the late answer. I wrote that feature request down, thank you. Kind regards, Martin

Hi Luis, from your screenshot it is difficult to identify the problem. Could you describe a little what is going on? And also, please provide the log file "PVSOLpremium.log" that you can find at C:\ProgramData\Valentin EnergieSoftware\log Thanks in advance, Martin

Hi Infinitech, no, it is really like this: The difference is, that it takes into account the height of the sun and its "power". If a shadow occurs at lower sun angles (morning or evening, or winter time), it has less impact on the overall percentage. If a shadow occurs at higher sun angles (noon, summer) it has high impact. Hope that clarifies the matter a bit further, kind regards, Martin

Dear Stuart, thank you for your feedback. We are having a lot of customer feedback about the GUI at the moment, and we are working on a solution. It seems that recent updates of Mircosoft Windows, as well as the .NET framework and additionally the handling of the dpi scaling changed. So it would be very helpful if you could provide a screenshot of the pages with the issues you mentioned, and - if possible - some information about your display settings. Thanks a lot in advance, kind regards, Martin

Hi Ragy, did you re-simulate the project with zero tilt? If the simulation results are not valid for the current system data, they are not shown. Kind regards, Martin ps: Glad to see that apparently your installation succeeded

Hi Ragy, this error is unknown to me, but it looks like a system issue to me. "msxml3.dll" is a system library located in C:\Windows\System32\. Can you see it in your system? Also be sure that no other process is accessing the PVSOL.ini file here: "C:\Users\USERNAME\Documents\Valentin EnergieSoftware\PVSOL premium 2020\PVSOL.ini" or, if you install PV*SOL premium 2020 for the first time, check this file: "C:\Users\USERNAME\Documents\Valentin EnergieSoftware\PVSOL premium 2019\PVSOL.ini" Hope that helps to identify the problem. Kind regards, Martin

Hi Marcin, from what I see on the picture there and also on their website (https://www.next2sun.de), there are only two bifacial modules per section, one on the top and one below. I think we can see it very clearly here on this picture: This system can be easily modelled in 3D right now, with the help of mounting system type 1: And, in order to get the vertical posts in the correct place, set the Support Points Distance to a value a bit smaller than the longer side of the PV modules. Hope that helps, kind regards, Martin

Hi Marcin, I am not sure if I understand correctly.. Do you mean, you have a vertical structure with two bifacial modules, one to each side? So that their backsides touch? Kind regards, Martin
