Hi grlnat, the 180 kWp is the so called peak power, measured at Standard Test Conditions (STC). The conditions are 1000 W/m² irradiance, 25 °C module temperature and and air mass of 1.5 (but that is not important here). That means, if your modules receive 1000 W/m² of irradiance and have 25°C module temperature, they will output 180 kWp. Accordingly, if the irradiance is lower or higher, the output of the modules will be less or more that the 180 kWp. The irradiance varies greatly during the year and during day. And of course, clouds can have a very strog influence on the irradiance. Clouds can even reflect parts of the sun rays, leading to so called irradiance enhancements. In those situations, the irradiance values can go far beyond their typical values. So, in a usual continental climate it is common to have irradiance values from 0 to 1300 W/m². That is of course, if you look at the values in one-minute resolution. https://help.valentin-software.com/pvsol/en/calculation/irradiation/ Hope that helps, kind regards, Martin

Hi Alejo, here is the translation of your question from deepl.com: There are several users with Windows 11 that have reported that issue. It might have something to do with a specific Windows Update, but so far we have no idea what exactly is causing the issue. This is really odd. You have a working piece of software, then Windows Update comes and only one particular part of the the software stops working. We have not had that kind of bug before, but we are continuing to investigate it. In the meantime you can still work with the "Fill Area" tool in order to get the modules on the roof: Hope that helps, kind regards, Martin

Hi Kitty, this is correct, the cable plan is currently disabled for polystring (multiple module areas on one MPP tracker). For SolarEdge configurations, the polystring option is enabled by default. If you only have one module area you can uncheck that option. Then you can use the cable plan feature: Hope that helps, kind regards, Martin

Hi Alain, if you have a 3d project, the module degradation is accessible here: Kind regards, Martin

Hallo bene-solar, das ist richtig, die Daten für den Symo 17.5 scheinen nicht aktuell zu sein. Ich werde das unserem Datenbank-Team weiterleiten, vielen Dank fürs Melden. Nein, das läuft etwas anders. Mehr dazu hier: https://help.valentin-software.com/pvsol/de/navigationsseiten/wechselrichter/anlagenpruefung/ Beste Grüße, Martin

Hi Alain, yes, the module degradation can be edited by the user: https://help.valentin-software.com/pvsol/en/pages/pv-modules/module-degradation/ Kind regards, Martin

Hallo Jons, könntest du mir das Projekt mal schicken, bitte? Gerne hier im Forum als private Nachricht, danke. Beste Grüße, Martin

Hi brownb, you can see a chart of the total generation per year here: You can also export the numbers by right clicking on the chart. Hope that helps, kind regards, Martin

Hi Alain, the module ageing losses (=degradation) are taken into account in the economic calculation only. The energy yield simulation is conducted for the first year only, without module ageing losses. You can refer to the energy balance after the simulation in order to see which losses are accounted for: https://help.valentin-software.com/pvsol/en/pages/results/energy-balance/ Hope that helps, kind regards, Martin

Hi CodrinSomesan, no, this is not possible, I am afraid. However, you can edit the Word file after exporting it. Kind regards, Martin

Hi CodrinSomesan, the same answer as in your previous post applies here: Kind regards, Martin

Hi CodrinSomesan, the number of DC inputs is not checked in the configuration section, since it is possible to combine strings before the DC input. You can use DC combiner boxes or Y connector cables or the like Hope that helps, kind regards, Martin

Hallo enick, vielen Dank für die Screenshots. Ich leite das mal in die 3D-Abteilung weiter. Beste Grüße, Martin

Hi Rodrigo, please see my response to your other post: Kind regards, Martin

Hi Kristoffer, sorry for the late reply, we somehow overlooked your question. The real output of your system really depends on a lot of factors. You can see the resulting output power over time om the results page, section "diagram editor", then time series or Carpet Plot. Just choose the series you want to see, e.g. "Energy at Inverter Input" and "PV energy (AC) minus standby use" (don't be irritated by the wording, the word "energy" is used because we use the texts mainly for results where energy values are displayed): You then get a time series plot like this: Or for the whole year: Or, as a CarpetPlot: Hope that helps, kind regards, Martin

Hi RachelEnergy, the field "Created by" is filled with the value of the Project Designer: "Approved by" and "Part number" can't be set from within PV*SOL, but only after you exported it. Best regards, Martin

Hi DrupoNduz, no, it has nothing to do with the version of PV*SOL, not with the license or anything else. It is really only related to the settings on your machine, I am afraid. Best regards, Martin

Hi Pierre, we had this issue a lot in previous versions of PV*SOL and had hopes that the problem would be solved. But then came Windows 11... we are still not sure why this happens even on unscaled screens. But in order to get the menu bar back, you can try the work-around from this post here: Hope that helps, kind regards, Martin

Dear DrupoNduz, yes, of course, I can export and see the csv export properly: Make sure your decimal separator and list separator of your system are exactly like on the computers of your colleague. Also make sure that the decimal separator setting in Excel is the same like your colleague's. Also the export settings in PV*SOL need to be the same. Then export the file again and open it in Excel. I wish you all the best for figuring it out! Martin

Hi juhaina, sorry for the late reply. Currently we have a very high volume of requests. Could you provide a project file, please? You can send it to me via private message here in the forum, thank you. Kind regards, Martin

Hallo Saj, diese Meldung kommt, wenn man verschaltet hat, aber eben nicht alle Details im Kabelplan eingegeben hat. Die Meldung kann ignoriert werden, wenn der Kabelplan so ausreicht, wie man ihn sieht. Beste Grüße, Martin

Hallo Andreas, das ist ein Bug, der uns bereits bekannt ist und für die nächste Version (premium 2023 R4) auch schon behoben wurde. Als Work-Around jetzt kann man die gesamte Simulation mit Strg+F5 neu anstoßen, dann klappt es. Beste Grüße, Martin

Hallo Jons, nein, leider gibt es diese Möglichkeit (noch) nicht. Wir haben diesen Feature-Wunsch aber bereits auf der Liste. Jetzt aktuell kann ich nur auf das Online-Tool für Wirtschaflichkeitsberechnungen der DGS Franken verweisen, die auch das Mieterstrom-Modell können: https://www.pv-now.de/ Viele Grüße, Martin

Hallo Jons, die Nummerierung der Wechselrichter ergibt sich aus der Reihenfolge im Verschaltungsdialog, damit bekommt man meist die gewünschte Reihenfolge hin: Beste Grüße, Martin

Hallo OGen, vielen Dank für die Anfrage. Wir simulieren nur das erste Jahr, und nur diese Werte sind im csv-Export enthalten. Die Werte der Degradation fließen nur in die Wirtschaftlichkeitsberechnung mit ein. Um abzuschätzen, wie sich die PV im Zusammenspiel mit dem Batteriespeicher verhält, müsste man eine Kopie des PV-Moduls anlegen und die Werte für Strom und Spannung gemäß der Degradation ändern. Der Einfachheit halber kann man dabei annehmen, dass nur der Strom des Moduls degradiert. Wenn das Modul also laut Datenblatt in 10 Jahren um 5% degradiert, müsste man in der Kopie des PV-Moduls alle Strom- und Leistungswerte um 5% reduzieren und dann damit simulieren. Beste Grüße, Martin
