Dear Aboud, the fraction of the generated PV energy that can directly be used by the loads is not a design parameter but a result of the simulation. In order to get more own consumption you would have to tweak e.g. the load profile (use a profile that matches the PV generation profile a bit better). In this manner you can get closer to the result that you want to get. But you can't just input It really depends on a lot of factors, like the simultaneousness of PV and load, the respective power values and more. Hope that helps, kind regards, Martin

Hallo maiya, zusätzlich zu den 1,5% Betriebskostensteigerung gehen die 2% Kapitalzins noch mit in die Rechnung ein. Setzt man diese auf 0%, bekommt man im Cash-Flow auch die 684 € im ersten Jahr. Viele Grüße, Martin

Dear Audrius, we calculate the rotation of the tracker for every time step of the simulation, i.e. every hour or every minute. More on trackers here: https://help.valentin-software.com/pvsol/en/pages/pv-modules/#tracking Hope that helps, kind regards, Martin

Hi hkb, Twisun is not yet in our database. While you can enter the module for your own use (https://help.valentin-software.com/pvsol/en/databases/components/pv-modules/), I will also forward your request to our database team. Kind regards, Martin

Hallo mamue, gerne leite ich die Anfrage weiter an unser Datenbank-Team. Beste Grüße, Martin

Hi aleks3981, the DC and AC cable losses on that page are only estimations based on STC conditions. During simulation we calculate the real losses that you can find in the energy balance afterwards. This is also included in the project report. Hope that helps, kind regards, Martin

Hi Venkatesh, could you send your inquiry by email to our hotline team at hotline@valentin-software.com, please? Thanks a lot and kind regards, Martin

Hi Eriic, we do have the OND file import feature on our list, and it won't be long until we start implementing. But for now I have forwarded your request to the database team so that they can contact Huawei directly. Thanks and kind regards, Martin

Dear Dosty, could you provide your project file please? You can send it to our hotline team at hotline@valentin-software.com. Thanks and kind regards, Martin

Hi chudy14, if it only for illustration purposes you could try to increase the limit of the maximum allowed number of modules. Close PV*SOL, open the ini file ("C:\Users\USERNAME\Documents\Valentin EnergieSoftware\PVSOL premium 2023\PVSOL.ini") and locate the line that says <MaxAnzModule>10000</MaxAnzModule> Try to change the value to a higher one and then re-open PV*SOL. Keep in mind that you may run into performance issues, but sometimes it works (depending on the machine and the actual project). Hope that helps, kind regards, Martin

Hi Mariusz Kordek, could you provide some screenshots perhaps? My first guess is that it might be caused by the regional settings in your Windows setup, perhaps you have unconventional decimal separators set? Kind regards, Martin

Hi Venco Gary, the reason why the top of the object is not selectable is that is a fireproof wall object. The intended use is just for small walls. Try to use an extrusion object, that will work. You can use the polygon tool for drawing the outline of the object and then right click -> Extrude. Hope that helps, kind regards, Martin

Hi Elcor, sorry for the late reply. 1. Unfortunately the video is not displaying for me, it just says "no video with supported format and mime-type found". And from your explanation I do not really understand the problem, I am afraid. 2. This is not possible at the moment, I am afraid. We do have this feature request on our list, but I can't give a date for that right now. Kind regards, Martin

Hi Abdel, you can do the following. Close PV*SOL, open the ini file with a text editor and locate the node named "LetzteProjekte". There you can just delete the lines that you don't want, save the file and then re-open PV*SOL. The ini file can be found here: C:\Users\<USERNAME>\Documents\Valentin EnergieSoftware\PVSOL premium 2023\PVSOL.ini Kind regards, Martin

Hallo Erdmann, ich bitte vielmahls um Entschuldigung für die späte Antwort, die Frage ist irgendwie untergegangen. Hier handelt es sich wohl um einen Eingabefehler von FoxESS. Bei uns in der Datenbank hinterlegt hat FoxESS nur den Hybrid-Wechselrichter AC1, in allen möglichen Kombinationen mit Batteriespeichern (das ist das, was auf dem Screenshot zu sehen ist). Als PV-Wechselrichter sollte also das gleiche Gerät gewählt werden, der aber leider nicht eingegeben wurde. Ich werde unserem Datenbank-Team Bescheid geben, dass sie FoxESS kontaktieren mit der Bitte um Überarbeitung und Ergänzung der Einträge. Vielen Dank fürs Melden! Beste Grüße, Martin

Hallo aqualx, tut mir sehr leid für die Verzögerung bei der Antwort, die Frage ist irgendwie untergegangen. Die MPP-Spannungen bei bestimmten Einstrahlungs- und Temperatur-Koeffizienten werden simuliert. D.h. je nach Modultechnologie kommt entweder das Zwei-Dioden- oder unser eigenes PV*SOL-Modell zum Einsatz, das mit den Datenblatt-Angaben (u.a. der Temperaturkoeffizient der Leerlaufspannung) parametrisiert wird. Mehr dazu hier: https://help.valentin-software.com/pvsol/de/berechnungsgrundlagen/pv-module/kennlinienmodelle/ Beste Grüße, Martin

Hi PV Modeler 1234, in this case it would be helpful if you could send the project file to me, as a private message here in the forum. Thanks a lot, kind regards, Martin

Hallo Frankos, diese Fehlermeldung kommt vor allem dann, wenn das Windows-User-Verzeichnis auf ein Netzlaufwerk gemappt ist. Hier geht es u.a. um den "Documents"-Ordner, auf den die Installation Zugriff braucht. Dieser Zugriff schlägt fehl, wenn das User-Verzeichnis mittels Laufwerksbuchstaben gemappt wurde. Wenn man es mit einer Server-Adresse mappt, klappt der Zugriff. Mehr dazu hier: Beste Grüße, Martin

Dear mina-io-group, could you please send us a screenshot with the problem? We know of a drag'n'drop related problem with Windows 11 22H2, but your problem seems to be different. A screenshot would help very much. Thanks and kind regards, Martin

Hallo powerix, ich habe mir mal erlaubt, deine Frage als neues Thema zu erstellen und ins deutsche Forum zu verschieben. Könntest du das Setup bitte nochmal starten? Wenn das Problem wiederholt auftritt, würde ich dich bitten, die Installation aus der Kommandozeile zu wiederholen, unter Angabe eines Pfades für die Log-Datei. Z.B. so: setup_pvsolpremium_2023_1.exe /LOG="pvsol-2023-1-setup-log.txt" Diese Log-Datei bräcuhte ich dann (gerne hier im Forum als private Nachricht). Beste Grüße, Martin

Hi PV Modeler 1234, I am not sure if I get the question right... do you try to load a project made with a newer version in an older version of PV*SOL? Most of the time, this won't be possible as our internal file format changes quite often from one version to another (major and minor). If it is something else that you're doing, please let me know. Kind regards, Martin

Dear anees, in general, if you have a valid maintenance contract, you can update to any version that we publish without issues. Please feel free to contact our sales team at sales@valentin-software.com along with your customer and serial numbers if you want to clarify this more in detail. Kind regards, Martin

Hi topper_back, the IRR is calculated on the basis of the cashflow, not just the initial investment. From the Microsoft Support Website: The approach you use in your example refers to the annuity calculation. Kind regards, Martin

Dear photovoltaique83, I am afraid I have to disappoint you in this regard, as I still can't give you a schedule about the implementation of this feature. Kind regards, Martin

Dear cüneyt, the currency is taken from the Windows settings. So you would just have to change the currency in your regional settings of Windows and then restart PV*SOL. Kind regards, Martin
