  1. Hi patrik k,

    the problem here is, that PhotoPlan is external software that was bought by us a long time ago. Due to the age there is no maintenance and neither do we have the source code nor do we have permission to change anything. This is why my standard answers refer to bitmap manipulating.

    I tried a bit, there is no recipe, but with brightness, contrast and some colour variation, you could achieve this:

  2. Hi Douglas,

    this is not intended and we are investigating this issue. Meanwhile you could use the inverters from the offline db by forcing PV*SOL to use the database from your harddrive. They are still in the database but are not visible somehow:

  3. Hi Faruk,

    I must admit, that I don't know the exact requirements of the certificate. The easiest way is to send an email to our sales team. They are happy to help you out: sales@valentin-software.com

  4. Hi patrik k,

    this is not possible with Photo Plan. There is a workaround, which takes about 5 minutes using GIMP, an open source bitmap manupulation program https://www.gimp.org/

    1. Open the picture
    2. Use the "Free Select"-Tool for selecting the module area
    3. Via Colors > Saturation set the saturation of the selected area to 0.0.
    4. Export the picture with the changes you made.

  5. Hallo Alexander Erber,

    entschuldige die sp√§te R√ľckmeldung, Deine R√ľckfrage war bei mir untergegangen. Und meine letzte Antwort war falsch! PV*SOL erkennt nicht automatisch ein Schaltjahr.

    • Bei den Klimadaten ist es so, dass der Schalttag, also der 29.02. im Voraus entfernt werden muss, ansonsten wird alles ab dem 29.02. um einen Tag nach hinten verschoben. Der 29.02. ist dann der 01.03. usw. Der 31.12. f√§llt weg.
    • Bei den Lastprofilen ist es so, dass vorher eingestellt werden muss, wie viele Zeilen im einzulesenden Lastprofil enthalten sind. In der Simulation werden ebenfalls nur 365 Tage genutzt.

    Der Unterschied zwischen den beiden Einstrahlungssummen r√ľhrt vermutlich daher, dass die Summen des 29.02. und des 31.12. √§hnlich, aber nicht gleich waren. Zur √úberpr√ľfung kannst Du mir gerne die beiden .dat-Dateien als private Nachricht schicken, dann kann ich einen Blick drauf werfen.

    Entschuldige nochmals die Falschinformation.

    Beste Gr√ľ√üe,
    Frederik

  6. Hi Frido,

    there is a bug regarding the configuration: A simulation with Polystring Configuration does not produce any results per module area. By unchecking Polystring Configuration the results per module area should be invisible in the project report. The problem here is, that the configuration did not change physically, so PV*SOL does not simulate again, since the simulation model is the same.

    ...which results to missing results per module area:

    Workaround: Force simulation, if results per module area are missing.

    This bug is fixed in upcoming version 2021 R6.

  7. Hallo Wolfgam,

    in diesem Falle handelt es sich bei den Meldungen nicht um Fehler, sondern Warnungen, die als unterst√ľtzende Hinweise dienen sollen. In der Hilfe sind diese hier aufgelistet: https://help.valentin-software.com/pvsol/2021/de/navigationsseiten/#meldungen-pvsol

    Das bedeutet, dass eine Simulation möglich ist! Durch Klick auf Ergebnisse wird simuliert.

    Die Situation auf der Seite Wechselrichter stellt sich dann so dar, dass alle Module verschaltet sind, zwei Warnungen auftreten und ebenfalls eine Warnung bei der Pr√ľfung der Verschaltung auftritt (rotes Kreuz), wenn ein kleiner dimensionierter Wechselrichter gew√§hlt wird (Dropdown-Men√ľ neben dem Hersteller):

    image.thumb.png.a1c115b658bd85ab52283e3f045e889c.png

    Ein Klick auf das rote Kreuzchen zeigt, dass wir eine starke Unterdimensionierung des Wechselrichters haben. Dies wurde wegen der Nordausrichtung bewusst gewählt:

    image.png.fda0a01915402f6da55418f886f627b6.png

    Auf der Seite Ergebnisse > Simulation > Diagrammeditor > Carpetplot zeigt das Diagramm des MPP1, dass die maximale DC-Leistung knapp unter 3kW beträgt:

    Ich hoffe, das hilft weiter!

  8. Hi Frido,

    sorry for being vague. The result found in the per module area is not correct. The reason: The simulation results are perfectly fine, we make a mistake by writing the wrong string into the project report. This becomes clearer when you look at the diagrams with the irradiation totals.

  10. Hello Lynette,

    a) yes, it is! You can export the simulation results to a character separated values file: https://help.valentin-software.com/pvsol/2021/en/pages/presentation/#simulation-results

    b) Yes, with the current 3D the highest resolution is 10 minutes. We are working on improving that for the new 3D

    We would be very interested in the results of this research project. This could provide many opportunities for improvement.

    Best regards,
    Frederik

     

  11. Hi LynetteOC,

    sorry for the belated response. This is correct, the irradiation is assumed to be constant throughout the hour. This again illustrates the importance of simulations with minute values instead of using hourly values. Those minutely data can be synthesized for every location: https://help.valentin-software.com/pvsol/2021/en/calculation/irradiation/synthesis-of-minute-values/
