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.

As simple "ctrl Z" or undo button would be extremely nice! Greetz Johan

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 text in the final report (for clients would be interesting if we can include in one only document the pictures of a visit for example or special information) 5 - BIM/ifc files compatibility. Thanks for your attention. Kind regards

Hat schon jemand "UNDO" gesagt ?

Hallo, ein praktisches Feature wäre, wenn man in der 3D-Planung häufig verwendete Unterkonstruktionen Projektübergreifend abspeichern könnte. Dadurch müsste man diese bei verschieden Projekten nicht immer wieder neu erstellen. Ist hierzu etwas angedacht?

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 picture added.

- would like to see an undo button as discribed above. (or at least be able to lock a complex building and their surroundings, so one misclick doens't destroy your work) - need more options for EV. (e.g. distance travelled per week day, range according new WLTP system) - while the software perfectly suits my technical needs, it seems lackluster/old as a client proposal. - could we have a blanc page in the customer presentation where we can add project or installer specific additional information. - some presentation pages need additional (customizable) information. (while a graph or scheme or just some numbers wth a title above will be very clear for us, a customer most of the time doens't know what he is looking at) - file size of the presentation should be smaller, but pictures should still be high res. - would like to be able to send an electronic presentation to a customer with some analytics possibilities. (where do customers actualy look at?) - easier construction of "complex" buildings. (depth of building schould be addapted to the angle and dimensions of the roof area being used for the array)

Der wird bei der Doku auf der Seite Ertragsprognose angezeigt. Hier beispielhaft (Wert ist gering, da es einen Teil Fassadenmodule gibt).

Try adjusting these two values and you will have it.

When rotating an object, deactivate collisions while doing so. I am often unable to rotate something because it hits another object while rotating. Also, it would be more intuitive if the object would rotate around it’s geometric centre, and not it's base point.

Hallo zusammen, Ich sehe auch eine dringende Notwendigkeit darin, dass man Wärmepumpen zusätzlich als Verbraucher anlegen kann. Bei unseren Anlagen haben wir zu 80% Kunden, die eine Wärmepumpe haben oder planen eine anzuschaffen und ihren Bedarf in den Simulation berücksichtigt sehen wollen. Oder gibt es eine Möglichkeit das Problem zu umgehen? Würde mich über ein life hack von Valentin freuen. Gruß, Iza

Many buildings have a lot of edges and must be drawn manually. But for these structures, it is not possible to add for instance tilting in several directions (which is possible for normal rectangular polygons that can be drawn). This is useful as most buildings have some tilt on the roof for water drainage: either with water chutes / gutter at the sides (like a gabled roof with low angle), or in the middle (opposite of gabled roof, as illustrated in the attached picture). Some buildings have several of these as well. PVSOL needs an option to add this, so that the correct incidence angle of irradiance on the PV modules is achieved.

Was ist der Unterschied zwischen Bibern und PV Sol? Biber verkraften mehr als 50 Bäume. Galgenhumor beiseite: - mein Wunsch: Begrenzungen von PV-Sol vergrößern. Ich meine sowas wie Modulanzahl, Bäume usw., das wär oft echt gut!

Would be great for the Production Forecast graph to show specific kWh values each month. For example:

Idee Teilanlage als Bestand deklarieren und damit die Wirtschaftlichkeit einer Erweiterung transparent machen können. Sprich: Die Erzeugung der Teilanlage der Bestands-PV (Wechselrichter mit Module) wird zunächst von dem Lastprofil abgezogen, anschließend wird die Rechnung mit der Risiduallast durchgeführt wie gehabt.

- Lizenzübertragung auf andere Geräte, ggf. mit Onlinezwang Ich arbeite gerade spontan notgedrungen aus dem Homeoffice mit Fernzugriff auf meinen PC im Büro per VPN wegen der Lizenz. Das ist grausam langsam und sporadisch stürzt leider auch das PV-SOL dabei mit den Grafikfehlermeldungen ab. Daher wäre es schön wenn die Lizens für einen Anwender auf mehreren Geräten laufen könnte. Es ist schwer zu erklären warum man zwei oder mehr Lizenzen für einen Anwender anschaffen soll, nur weil verschiedene Geräte an unterschiedlichen Orten durch einen Anwender genutzt werden. Da die Software beim Start sowieso nach Hause telefoniert, könnte auch der status aktiv/inaktiv protokolliert werden und bei Doppelnutzung eines Accounts der Start verwehrt werden. Oder habe ich eine andere Lösung für diese Anforderung übersehen?

Hallo Daniel, Wenn ich Sie richtig verstehe (mein Deutsch ist nicht sehr gut, ich habe das übersetzt), möchten Sie die Stückliste in eine csv-Datei exportieren. Es könnte einfacher sein, wenn ich nur einen Screenshot zeige, wo Sie es tun. Mit freundlichen Grüßen, Jimmy

Hallo, es wäre praktisch wenn in der 3D-Visualisierung und einem geöffnetem Dialogfeld der Zoom mit dem Mausrad an der Stelle des Mauszeigers rein und raus zoomen würde anstatt an einer fixen Position. Also so, als ob das Dialogfeld nicht geöffnet wäre.

Hi Sondre. Yes. When you're in the "module configuration" view you're actually able to drag panels around. All panels are automatically numbered when you do the inverter config and they'll keep their number no matter where you move them. And the string go in order of panel number. Here's a screenshot of your desired result. An alternative method is in "cable plan" where you can use the "Sketch module cables" tool. Just select the tool and start at the first panel and draw the string going over each module in order. I prefer to move the panels in the module configuration view but I think both are equally valid.

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 the neibourhood. Orange buildings highlight PV systems within public view, lighter buildings highlight PV systems with limited public view, grey buildings highlight properties outside consideration. The image went down so well it was reported the contractor specially printed this at poster size to show and tell to Prince Charles of Wales.

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 boxes, different cable sections, strings combined into arrays, etc, it all disappears into ONE SINGLE magic number. Just as @timgreen13 pointed out, one is expecting to see cable losses by section, see individual string lengths and losses, etc, because if not then what's the point of all that detailed "painting"? We need to check if individual strings and individual arrays are above our own loss thresholds, to be able to correct them if necessary. Having just one global loss number won't let you see that, you might even have 5% losses in one string branch and get 0,8% global losses in the system. Again I'm in the position of having this powerful software (PVSOL) I paid for that won't do basic functionality, and having to go back to freeware manufacturer software (SUNNY DESIGN) to get some of the design steps done. After fine tuning the strings and cable sections on SUNNY DESIGN I will have to go back to PVSOL and try to input MPPT equivalents... can you see how cumbersome this is? The more I work with PVSOL the more frustrated I get, really, it should be the opposite. You guys do the most difficult part, the math simulations, to unimaginable precision (congrats on that!), and then fail at the most basic functionality and design elements. Go figure...

Hi Ahmad Elghobashy, the performance ratio is the ratio between the actual pv energy and the theoretical maximum pv energy. The actual pv energy is, as you have already mentioned, the "PV energy (AC) minus standby use", but the theoretical maximum is not the "Rated PV Energy", because there are already some influences on the radiation like soiling and reflection. The correct formula for the performace ratio (PR) is: PR = ("PV energy (AC) minus standby use") / (" Global Radiation at the Module" - "Reflection on the Module Interface") * module area * module efficiency )) In your case, that would be: PR = 114,960.40 kWh /[(2,041.7 kWh/m² - (- 33.13 kWh/m²)) * 414.11 m² * 0.1681] PR = 0.79594 = 79.6 % Kind regards, Marcel

Hi, I was wondering, is there an option to undo changes in PV SOL, other than not saving and simply opening the last saved version of your file? Something in the line of Ctrl+Z in MS Office. Thanks!

Hi Boris, yes, no problem. You can download the setup file for PV*SOL premium 2024 R6 here: https://downloads.valentin.de/pvsol/setup_pvsolpremium_2024_6.exe You can also install R6 and R7 side by side if you choose a different installation directory. Kind regards, Martin

Hallo its_dd, ein Gebäude mit Mansardendach erstellen Dachgeschoss1 an gewünschte Werte anpassen Dachgeschoss2 an gewünschte Werte anpassen Gebäude kopieren Anschließend das gedrehte Gebäude kollisionsfrei schalten und in das vorherige Gebäude schieben Mit Hilfe von Sperrflächen lassen sich die nutzbaren Modulflächen eingrenzen Ich habe mir es beim zweiten Teil einfach gemacht und das gleiche Gebäude ein zweites Mal genutzt. Das ließe sich natürlich schöner machen. Freundliche Grüße, Frederik

Ich vermisse ein richtiges Handbuch. Das letzte ist schon etliche Jahre alt, die Online-Hilfe ist lückenhaft. Einige der Parameter für die Definition von Komponenten in der Datenbank sind nicht erläutert oder definiert. Das macht es für die Ersteller von Komponenten schwierig, diese korrekt anzulegen. Schön wäre ein Glossar / Nomenklatur, in der alle vorkommenden Begriffe und Parameter erläutert und definiert sind (Definitionsgleichung und Erläuterung, wie dieser Parameter in die Simulation eingeht). Ich glaube, dann gäbe es auch weniger fehlerhafte technische Daten in der Datenbank.

Ich bin ziemlich neu bei PVsol, aber das kann ich nur unterschreiben, die 3D-Navigation hat noch erhebliches Potential zur Verbesserung. Es fühlt sich einfach furchtbar hakelig an. Was eigentlich jedes CAD-Programm heute bietet (auch kostenlose wie z.B. Freecad): Drehpunkt der Ansicht wird vom Benutzer gewählt Wenn schon nicht wählbar, dann sollte er wenigstens sinnvoll liegen, z.B. im Volumenschwerpunkt des aktiven Gebäudes oder im Flächenschwerpunkt der Gesamt-Grundrissfläche) Beliebig weit rein- und rauszoomen Keine Drehwinkelbegrenzung, ich kann mir mein Objekt wenn ich will auch von unten angucken oder siebenmal linksrum drehen. "Autoscale" Button, um das Objekt bei maximaler Größe in die Mitte zu rücken (das kann sogar Paint) Umschalten zwischen orthogonaler und perspektivischer Ansicht In orthogonaler Ansicht sieht manches nicht so schick aus, aber es entfallen einige unangenehme Kopplungen zwischen Rotation und Translation beim Verschieben KEINE automatische Umschaltung des Blickwinkels beim öffnen einer anderen Workbench

Hey everyone, since there isn't much information about Intune and PV*SOL, I'd like to share some updated knowledge, for anyone in need: To Update PV*SOL you can simply run the setup file for the newer versoin on the machine with the older version. You can get the newest version here: Download Testversionen | Valentin Software (valentin-software.com) (If the License Key of the User is already registered on the machine, it will automatically run the licensed version) I've also had the issue of corrupted files, when I updated from 2024 R2 to 2024 R3. I simply fixed it by running the setup file twice on the machine. My install.cmd file which is the setup file for Intune: (Yes, it installs twice just in case) START /W setup_pvsolpremium_2024_3.exe /LANG=DE /VERYSILENT ECHO Back from setup_pvsolpremium_2024_3.exe START /W setup_pvsolpremium_2024_3.exe /LANG=DE /VERYSILENT ECHO Back from setup_pvsolpremium_2024_3.exe The Uninstall command: %programfiles(x86)%\Valentin EnergieSoftware\PVSOL premium 2024\unins000.exe" /SILENT This only deinstalls the specific version (depends on the year) inside it's path. Therefore you might want to uninstall the older version of the previous year, after the new version was successfully deployed. Detection Rule: The Developers created a text file of requiered files inside %programfiles(x86)%\Valentin EnergieSoftware\PVSOL premium 2024\RequiredFilesProgramData.txt if you want to make sure the program will run after a successfull installation, you might want to include one of these. Here are my Detection Rules: File Path: %programfiles(x86)%\Valentin EnergieSoftware\PVSOL premium 2024\ File or Folder: PVSOLpremium.exe Detection Method: File exists Associated with a 32-bit app on 64-bit clients: YES File Path: %programdata%\Valentin EnergieSoftware\MeteoSyn\meteonorm\8.2\ File or Folder: acsd_all4_mes_c.txt Detection Method: File exists Registry Path: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\PVSOL premium 2024_is1 Value Name: DisplayVersion Detection Method: String Comparison Operator: Equals Value: 2024.3 Associated with a 32-bit app on 64-bit clients: YES → The Value of the Registry DisplayVersion changes with each update Dependencies: Photo Plan → automatically install To get Photo Plan to run I had to extract the MSI out of the setupPhotoPlan.exe from this Link https://downloads.valentin.de/photoplan/setupPhotoPlan.exe . Simply run setupPhotoPlan.exe and leave the Setup Window open. Afterwards you can find the Photo Plan.msi File in %localappdata%\Temp . Now you can package a Win32 App with the Photo Plan.msi as the setup file. Intune will fill out the remaining fields automatically. Reminder: If you mix Win32 Apps and Line-Of-Business-Apps in your ESP, Autopilot might fail. Have fun !

Ist dieser Fehler gute 2,5 Jahre später mal in Bearbeitung gewesen? Sieht doch super dämlich aus, wenn ich dem Kunden sein Haus falsch zeige oder auf einer Seite noch ein 90° Dach nach unten habe.V

For flat roof installations: Is it possible to choose if the distance between mounting support can be on the high side vs. the low side? See example attached

It would be nice to have a measuring tool. That is, "a ruler" tool to check different distances that cannot be found from object information.

Hi reebal, nein, das ist derzeit leider nicht möglich. Wir haben das schon einige Zeit auf der Liste, aber zur Zeit kann ich leider keinen Ausblick geben, wann wir das Feature implementieren werden. Beste Grüße, Martin

Hi Patrik I am using a DJI Mavic 2 enterprise and take a lot (>100) of overlapping pictures. Than I use WebODM to create a 3D model after that you need to clean up the model with Meshmixer for PV*Sol usage. For my purposes these 3D models arre sufficient. Greetz Johan

Hallo Josua, das geht leider nicht, weil diese Objekte topologisch in keinem Zusammenhang stehen. Ich habe die Anfrage an unseren 3D-Entwickler weiter geleitet. Viele Grüße, Frederik

Hallo Akram Ich versuchs mal: Die Einspeisung kannst du nicht entfernen. Der Grund warum "nur" 40% der erzeugten Energie für den Eigenverbrauch verwendet wird ist, weil zum Zeitpunkt der Erzeugung schlicht nicht mehr selbst brauchen kannst. D.h. Tagsüber wenn die Sonne scheint erzeugst du mehr als du zu diesem Zeitpunkt selbst verwenden kannst. Und dieser Überschuss geht dann als Einspeisung ins Netz. Mindestens theoretisch könntest du ohne Einspeisung arbeiten wenn du immer weniger Erzeugen würdest als du selbst verbrauchst, in der Praxis ergibt das aber keinen Sinn. Viele Grüsse Oliver

Hello, I Have checked compatibility** from Enphase IQ-7A-72-2 with *SPR P3 385Wp panel. It says it is possible till 15A max. (Panels* are 10,63A Rated Current*** (Impp) & 11,3A Short-Circuit Current (Isc) (+/−3%). **https://www4.enphase.com/nl-nl/compatibiliteit-micros#results But in PV Sol after 10,2A it refuse to accept this combination. I know why this happen. Because the small letters from enphase datasheet: ""3. Maximum continuous input DC current is 10.2A."" Strange that Sunpower sells this combination with garranty.... how? And i cannot select this combination after copy this inverter and adjust limit settings in PV Sol from ***10,2A to 11A. First i thougt it was a fault in PV Sol. But now i see it is because the Enphase specs. I will contact them. Now PV sol will not suggests the Enphase micro inverter. Just someting to share. Where sometimes it gets stuck in work preparation. Regards, Martijn (OTG.energy)

Hi Pietro, @TurtlesOGhad the same problem about a month ago, see the post here:

Hi Mihail, This is, as far as I know, a sparsely reoccurring issue for some users and the topic is raised every few month from users. I've had this issue myself in the 2019 version but then it got better and never happened again. Anyway, the fix that worked for me and seems to fix it the best is here (basically run as admin and select high DPI settings):

HI Jimmy, yes this is possible. Please refer to this thread here: Kind regards, Martin

Satellite image for reference

Hi there! What format you are using for your 3D model? Here is a document with a list of supported formats: https://www.valentin-software.com/wp-content/uploads/legacy-downloads/sonstiges/en/3d-recherche-rev-01-en.pdf I have had the best results using .dae or .obj files in the past. However, I have found 3D models to be very unreliable (invisible walls that casting shade, module areas floating mid-air after saving the file etc.) so personally I try to avoid them when ever possible. Hope this helps. Regards, Frido

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

Main input parameter for this is "electricity tariff from grid" which one provides as input

Hey there, It follows the order Inveter.MPPT.String.Module Hope that answers your question. Cheers!!

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

If the program was released after your maintenance ends, the program will start as test version. To fix this : Uninstall this version and install a version released before your maintenance end. Renew the maintenance.

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

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. The difference between the shading by the horizon line and the near shading objects is that if the sun is behind the horizon line, there is only diffuse irradiance. There is also no shadow caused by direct sunlight since there is no direct sunlight anymore. Near shading objects however can cast a hard shadow on the pv system, depending on the sun's position and the geometries of the object and the pv systems. Those shadows can lead to important changes to the I-V characteristics when parts of the pv system receive full irradiance and others only the diffuse fraction (as described here: https://help.valentin-software.com/pvsol/2018/calculation/pv-field/ ). Hope that helps, Martin
