Hi Codrin Somesan, this is a known bug and will be fixed in PV*SOL premium 2023 R4. In the meanwhile you can use the shortcut Ctrl+F5 as workaround. Hope that helps, kind regards, Martin

Hi Solar-engineering, could you give an example where the output is not like you expected? The best would be a project file illustrating the problem. Thank you, kind regards, Martin

Hi juhaina, it seems that your 3D model from sketchup has inverted normals on the blue objects. Please check them in Sketchup and try not to invert them. Also you could add a gap in the attica somewhere to help the shading algorithm avoiding errors. Kind regards, Martin

Hi Andrii2, the project report is already available in Ukrainian: Hope that helps, kind regards, and all the best for your country Martin

Hallo Sunny-RP, ein direkter Export der Datenbanken ist nicht möglich, nein. Man kann jedoch die Ausgabe der Datenblätter der im Projekt verwendeten Produkte (Module, Wechselrichter etc) im Projektbericht aktivieren. Den kann man ja als docx exportieren, und darüber kommt man gut an die Daten ran. Was auch geht, ist die direkte Nutzung unserer Online-Datenbank über die API: https://valentin-software.com/produkte/api/ Bei Interesse einfach an den dort angegebenen Kontakt wenden, danke. Viele Grüße, Martin

Hi Ellie, Yes, we plan to implement this functionality this year, but I can't give an exact date yet. As a first approach, the AC connection workaround works quite well, but as you mention, you have to be careful with the parameters. Another option would be to skip the shading calculation of your 3D project. Due to the mechanics of the underlying simulation algorithm, the DC connection problem only occurs when there are shadows in 3D. Kind regards, Martin

Hi RachelEnergy, what I meant was that if you export it as an svg, you can edit it with any vector based drawing software. Personally I find inkscape a very good choice, it is free and open source and very powerful. After editing, you can easily save it as pdf for example. Kind regards, Martin

Hi Man, the diagrams that you mention are available if you choose "Surplus Feed-in" on the Economy page: If you choose Net-Metering, these diagrams are not available. Hope that helps, kind regards, Martin

Hi CodrinSomesan, for checking that we have the configuration check: There you can see if all voltage and current limits are not exceeded. (you can click on each tick mark and see more detail). Kind regards, Martin

Hi Codrin, thank you for clarifying your question. The number of strings in the configuration section is independent from the number of DC inputs of the inverter. When you connect two strings (=parallel strings) to two DC inputs on one tracker, they are combined inside the inverter. If you combine them outside of the inverter using whatever connector you want, you get the same results. If in PV*SOL you read 3 strings x 14 modules in series, it means that you have three parallel strings of 14 modules each. If you have two DC inputs per tracker and you want to connect three strings, you'll have to use at least one connector (like the Y connector shown above) outside of the inverter. But you are right, we could give a notice to the user that the total number of strings is exceeding the number of DC inputs. Thanks for pointing that out. Kind regards, Martin

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
