Hallo Ralf, ja, dieses Problem in der Darstellung gibt es leider. Es tritt nur in 3D auf, wenn auf zwei Modulflächen unterschiedliche Modultypen verwendet werden. Der Fehler bezieht sich aber tatsächlich nur auf die Anzeige, unter der Haube wird dann alles korrekt weitergerechnet (z.B. in der Verschaltung oder der Simulation). Beste Grüße, Martin

Dear Alex, in PV*SOL, there are three possibilities to calculate the economics of a PV system: For offgrid PV systems (not applicable in your case) For ongrid PV systems with net metering For ongrid PV systems with surplus feed-in Wether you have net metering or surplus feed-in depends on your country and electricity utility (or energy contracter). n your case it sounds more like a surplus feed-in. That is, self-consume a certain amount of the produced PV energy and sell the surplus to the utility or another customer. You can set the economic parameters on the page "Financial Analysis". https://help.valentin-software.com/pvsol/2021/en/pages/financial-analysis/ Hope that helps, kind regards, Martin

Dear Gianni, the problem that was reported was from PV*SOL premium 2019 R10. The most current version of our software is PV*SOL premium 2021 R3. Please consider updating, as there are a lot of bugfixes and new features. https://valentin-software.com/en/products/pvsol-premium/ Kind regards, Martin

Hi Jordn, in this case I would recommend to contact SunPower directly. https://us.sunpower.com/support/contact-page I'd guess that any information that you can find on the web will have some sort of credibility issue and won't clarify your doubts in the end. Kind regards, Martin

Hello Gytis, yes, that is possible. In the configuration page check the option "Power Optimizer" and then set the amount of modules you want to connect to each power optimizer at the end of the line: Hope that helps, kind regards, Martin

Hi Sondre, first of all let me wish you a happy and healthy new year 2021! Most of the time the difference lies in the energy consumption of the inverters during standby or night. You'll have an amount of energy that is fed into the grid (in your case 73964 kWh), but you also have a small amount of energy that is consumed by the inverters and taken from the grid. The balance of both is the "PV Generator Energy (AC grid)". Hope that helps, kind regards, Martin

Hi Rick, first of all let me wish you a happy and healthy new year 2021. Setting up offgrid or backup systems is always a bit difficult since all devices handle the responsibilities (like battery charging, providing a grid, energy flow management, PV MPP tracking, PV DC/AC conversion etc.) a bit differently. I had a look at the Schneider XW website, but there a many possible solutions to connect and combine their products. Would it be possible for you to provide an approximate schematic of what devices you want to connect in your setup? Thanks a lot in advance and kind regards, Martin

Hi Aneta, you can find the tracking system on the page "PV modules" that is visible if you uncheck the option "Use 3D design" on the page "System Type, Climate and Grid". Hope that helps, kind regards and a good start into 2021, Martin

Dear semiht, first of all let me wish you a happy and healthy new year 2021. Could you provide me the project file, please? That would make it easier to answer your question. You can send it here in the forum by private message. Kind regards, Martin

Dear Pro GD Engenharia, I translated your post with deepl.com, I hope it is correct: Would it be possible for you to send the 3D model file over to us so that we can have a look? Please send it here in the forum by private message, thanks. Kind regards, and a good start into 2021, Martin

Hallo Johann, ein frohes und gesundes neues Jahr 2021 wünsche ich zunächst! Leider kann ich aus deinem Post nicht direkt ableiten, was genau die Frage ist, bzw. was eine hilfreiche Antwort wäre. Kannst du näher ausführen, wo es klemmt? Beste Grüße und einen guten Start, Martin

Hi Miguel, that is correct, in PV*SOL you can't design an offgrid system with just PV, charge controller and batteries. The offgrid systems are limited to the connection over an AC bus, and in general, energy-yield-wise, it should be ok to design the system as AC system in PV*SOL, even if it is DC in reality. You'd have to set the PV and battery inverter efficiencies correspondingly. In terms of "overall efficiency" it really depends on the devices that are used. See also these threads for more information: Kind regards, Martin

Hallo Frank, auf unserem Youtube-Kanal solltest du fündig werden: https://www.youtube.com/user/valentinsoftware/videos Hier ein zweiteiliges Webinar auf deutsch: Viel Erfolg und schöne Feiertage, Martin

Hallo SunForFree, die Wärmepumpe kann entweder als Standardlastprofil ausgewählt werden (bei der Anlagenart "Netzgekoppelte PV-Anlage mit elektrischen Verbrauchern"), oder detailliert parametrisiert werden, dann auch einer eigenen Seite, nicht bei den Verbrauchern (Anlagenart "Netzgekoppelte PV-Anlage mit elektrischen Verbrauchern und thermischem System"). Die Anlagenart lässt sich auf der Seite "Anlagenart, Klima und Netz" einstellen. Beste Grüße, Martin

Hi crobecerra, yes, you can use PV*SOL for this purpose. You can enter your mechanical equipment with arbitrary power and with various options. If you have good information on the equipment, I guess that the option of "individual appliance" would be the best way to go: https://help.valentin-software.com/pvsol/2021/en/pages/consumption/ You can then define the battery system and backup generator, if you wish. There are several ways of controlling the energy flow (SOC-based, time-based, load shedding and so on), I think you will find out very quickly. Kind regards, Martin

Hi Joe, Windows Vista an Windows 7 are not supported anymore, I am afraid. You should really consider to update to Windows 10, since also Microsoft dropped official support for those operating systems (for Windows Vista in 2017 already, for Windows 7 in January 2020). https://www.microsoft.com/windows/windows-7-end-of-life-support-information Microsoft won't provide updates, security patches and so on. It is really a security risk running those operating systems. Kind regards, Martin

Hallo Gerald, die Diagramme und viele Ergebnisgrößen sind nicht zu sehen, wenn auf der Wirtschaftlichkeitsseite als Einpeisekonzept nicht "Überschusseinspeisung", sondern "Net-Metering" steht. Ich hoffe, das hilft weiter. Beste Grüße und einen guten Start in die Woche, Martin

Hallo SunForFree, ja, das geht. Eine Wärmepumpe lässt sich in PV*SOL premium ab Version 2021 R1 mit planen. Auch mit den erwähnten Abschaltzeiten. Beste Grüße, Martin

Hallo Ralf, es tut mir leid zu hören, dass die Ordnerwahl bei dir so verrückt spielt. Ich es habe versucht, bei mir nachzustellen, aber bei mir wird immer das Installationsverzeichnis PV*SOL premium standardmäßig geöffnet. Warum sich der Meteonorm-Ordner öffnet, ist mir ein Rätsel. Könntest du mir mal die ini-Datei schicken, die du unter "C:\Users\<USERNAME>\Documents\Valentin EnergieSoftware\PVSOL premium 2021\PVSOL.ini" findest. Aber bitte als private Nachricht hier im Forum. Dass sich am besten der zuletzt ausgewählte Ordner gemerkt werden sollte, stimmt aber natürlich. Das werde ich weitergeben, bzw. auf die Liste setzen. Danke für den Hinweis. Beste Grüße und einen guten Start in die Woche, Martin

Hi keirm, did you try to apply this work-around here: This should be fixed in the new release, PV*SOL premium 2021 R3. Could you provide a screenshot, please? Also, does this behaviour disappear when you apply the above mentioned work-around? Hope that helps, kind regards, Martin

Hi Chris, the electricity savings are calculated with the energy that you don't have to draw from the grid (because you have a PV system now), multiplied with the costs of electricity from grid (in €/kWh), which is defined in the from-grid tarriffs, as Vishnu correctly pointed out. Let's say you have a consumption of 5000 kWh per year. Usually you pay 0,25 €/kWh to the electricity company, that is 1250 € per year. Now with your PV system you can use 1500 kWh of your produced solar energy directly to cover your consumption, so you only have to cover the rest of 3500 kWh from the grid. For those 1500 kWh you don't have to pay your electricity provider, so you save 1500 kWh * 0,25 €/kWh = 375 €. Hope that clarifies the matter, kind regards, Martin

Hi Josef, Usually the runtime should install itself during the PV*SOL installation, but sometimes this fails. You can install a newer version of the .NET framework, at least version 4.7.2., by hand. Visit the following link, download the runtime and install it on your machine. https://dotnet.microsoft.com/download/dotnet-framework/net472 Choose to install the runtime, not the developer pack. Kind regards, Martin

Dear Petros, we do have that feature on our list, but right now I can't tell a date. It is not scheduled yet, I am sorry. But there are plenty of tracking options (backtracking modes included) in the main application. https://help.valentin-software.com/pvsol/2021/en/pages/pv-modules/#tracking Kind regards, Martin
