Dear Majd Elewi, there are several areas of PV*SOL premium where you can import data from other programs and in different formats. For example, you can import you own climate data (e.g. from Meteonorm or Meteotest or any other climate data provider). Or you can import your own load profiles (usually in *.csv or *.txt format). In the 3D environment you can import 3D models from nearly any 3D modelling software that exists on the market - we support the following formats: Program / Format Extension Collada (.dae) Blender 3D (.blend) 3ds Max 3DS (.3ds) 3ds Max ASE (.ase) Wavefront Object (.obj) Stanford Polygon Library (.ply) LightWave (.lwo) Stereolithography (.stl) DirectX X (.x) Milkshape 3D (.ms3d) In the 3D environment you can also import any picture (jpg/png/bmp) like floor plans, satellite or drone imagery and so on. I hope this answers your question, kind regards, Martin

Hallo Engelen, automatisch geht das Einfügen von thermischen Trennung leider (noch) nicht, das müsste man händisch machen. Also jeweils Reihen von 11 Modulen (bzw. 22 wegen Ost/West) aufziehen und so platzieren, dass dazwischen der Abstand für die thermische Trennung oder Wartungsgänge entsteht: Beste Grüße, Martin

Hallo Jan, für Österreich ist der Klimadatenzeitraum 1991 bis 2010 immer noch der aktuellste. Für Deutschland konnten wir den Zeitraum auf 1995-2012 aktualisieren und arbeiten daran, dass für die anderen Länder der Zeitraum 1996-2015 kommt. Einen genauen Termin für die Integration können wir aber derzeit leider nicht nennen. Beste Grüße, Martin

Hi Charita, I am not sure if I understand your question correctly. But connecting 20 modules per string to MPPT 1-2 and 18 per string to MPPT 3-10 should be no problem. It all depends on the PV modules and the inverter with their respective electrical data. But if you enter your system design in PV*SOL, you will get precise feedback if your configuration is good or not. Hope that helps, kind regards, Martin

Hi Burak, the 0,4 ct/kWh is the so called "Management Prämie" that shall compensate for the extra cost that a PV system owner has when he or she is opting for the "Direktvermarktung" In the numbers published by the "Bundesnetzagentur" those 0,4 ct/kWh are already included: https://www.bundesnetzagentur.de/SharedDocs/Downloads/DE/Sachgebiete/Energie/Unternehmen_Institutionen/ErneuerbareEnergien/ZahlenDatenInformationen/PV_Datenmeldungen/DegressionsVergSaetze_11-01_21.html They provide an Excel file that you can download, and in there there is a sheet called "Beispiele". There they state: As you can see, the 0,4 ct/kWh are already included (and have to be subtracted if not opting for Direktvermarktung). In PV*SOL, the tariffs are up-to-date and can be used as-is. Notice the 0,4 ct/kWh difference: I would also recommend these pages here, they explain the whole thing quite well: https://www.next-kraftwerke.de/wissen/managementpraemie Kind regards, Martin

Hi Ricardo, the active power will be capped. The output power clipping is based on the apparent power, say S_max. With cos φ = 1, the system will not produce reactive power, so active power equals apparent power, and the maximum power output is P_max = S_max. When the cos φ is smaller than 1, the maximum active power output will be reduced by this factor (while the maximum apparent output power remains the same), since P_max = S_max * cos φ. Hope that helps, kind regards, Martin

Dear Ricardo, unfortunately we don't have a detailed explanation of each item of the energy balance yet. But this is a good suggestion, we will put it on our request list for extending the help pages. The "Down-regulation on account of the max. AC Power/cos phi" takes place when the AC power of the PV system is higher than the maximum AC output of the inverter. In this case the inverter has to regulate the output power down to the maximum permissible power (by choosing another poit on the IV characteristics if the PV field on the DC side). The cos phi will reduce the maximum permissible power output of the inverter, of course, if not equal to 1. Hope that helps, kind regards, Martin

Dear Muhammad, that is correct, the number of battery systems is limited to 20 at the moment. In the case of your system it wouldn't help to make the battery system bigger however anyway, as the produced PV energy is by far smaller than the energy consumed by the electrical appliances (781 000 kWn PV energy vs 2 174 000 kWh load). The PV energy is already completely self consumed by the electrical appliances and the charging of the battery system, only 1265 kWh go into the grid. So making the battery system bigger wouldn't change anything, as there isn't more PV energy to make use of. But besides that we put the request on our list to allow for more than 20 battery systems in future. Hope that helps, kind regards, Martin

Hi Burak, the term EEG refers to the German law "Erneuerbare Energien-Gesetz", so if your PV system isn't located in Germany, these tariffs are not applicable for your system. If your system is in Germany, however, you can choose if you want to receive the standard EEG tariffs (which basically means that you are selling the energy to your utility company to a fixed rate that is defined by the law, the EEG). Or you can choose to sell your energy directly to a third party, which is called "Direktvermarktung". In this case you receive payments from two sources: Your customer pays for the electricity that you are selling, and in addition you receive a "Marktprämie" from the utility that covers at least the difference between the energy price at which you are selling and the fixed feed-in tariff from option 1. You will find a lot of resources on the internet if you search for ""EEG Marktprämienmodell", but of course, most of it will be in German. Hope that helps, kind regards, Martin

Hallo Raimund, das hybride Betriebsverhalten (bzw. den "MultiFlow") der Fronius Symo GEN24 Geräte können wir in PV*SOL in der Form leider nicht simulieren. Was aber geht, wäre, eine Kopie des Batterie-Systems anzulegen und die Kopplungsart auf AC umzustellen. Dann würden beide PV-Wechselricher AC-seitig mit dem Batterie-System gekoppelt werden und damit würde sowohl die Alt- als auch die Neu-Anlage zur Ladung der Batterie beitragen können. Zum Anlegen einer Kopie einfach neben der System-Auswahl auf "Detaillierte Auswahl" klicken: Dann im Datenbank-Dialog eine Kopie erzeugen: Und AC-Kopplung einstellen: Das neue Batterie-System dann speichern und im Projekt verwenden. Natürlich ist das rein technisch etwas anderes als die kombinierte DC- und AC-Ladung, aber energetisch sollte es trotzdem ganz gut hinkommen. Beste Grüße, Martin

Hei Thomas, the 50% come from the view factor approach that is used in this model. In short, you have to determine how much of the reflected irradiance of surface A1 can reach surface A2, if we assume that the irradiance is evenly distributed and that the irradiance reflects from the ground evenly in all directions. You can read a more detailed description here: https://pvpmc.sandia.gov/modeling-steps/1-weather-design-inputs/plane-of-array-poa-irradiance/calculating-poa-irradiance/poa-ground-reflected/ ad 2) No, sorry. These objects do only serve as shadowing obstacles in PV*SOL, not as sources of reflected light, I am afraid. Kind regards, Martin

Hi again, thanks for the files. What happened here is that both your list separator and your decimal separator are commata (,). This can't work. Try to set the decimal separator to a point (this is a Windows system setting) or set the list separator for the export in PV*SOL to a semi-colon (;), like so: Hope that helps, kind regards, Martin

Hi Muhammad, when importing or viewing the csv data in Excel, you should make sure that the decimal separator (point or comma) in Excel is set correctly. Open the csv file that you exported from Excel with a text editor Check which decimal separator is used Open Excel (without having the csv file opened) Go to File -> Options -> Advanced and set the decimal separator as found in the csv file Then open the csv file in Excel Hope that helps, kind regards, Martin

Hi Johan, these artefacts should have been solved with the release of PV*SOL premium 2021 R3. Do have this version installed? Kind regards, Martin

Hi Johan, the company will appear in the company list box if it has at least one product of the current product type. So to create the first product of a product type for a new company you will have to select it from the company dialog, like so: Hope that helps, kind regards, Martin

Hi Alex, the first point, the feed-in / export tariff is what you get from your utility company for each kWh that you feed into the grid. Using the green plus button on the right, you can define various steps depending on the pv system size in kWp or the energy fed into the grid (kWh). The second option, the own consumption, is what you get for directly consuming your the energy that you produce with your PV system. Or, in some cases, you have to pay for using your own energy (e.g. in Germany), so there is also the option for entering a fee. Hope that helps, kind regards, Martin

Hallo bene-solar, vielen Dank für die Dateien. Da hat sich leider ein Fehler eingeschlichen, der dafür sorgt, dass bei Minutenwerten die Ergebnisse im Projektvergleich nicht mehr angezeigt werden. Wird im nächsten Release behoben. Bis dahin müsste man den Projektvergleich in Stundenwerten verwenden. Viele Grüße, Martin

Halle bene-solar, tut mir leid, ich hatte nicht gesehen, dass meine Inbox hier im Forum voll ist (hab auch keine Warnung bekommen leider). Hab ein wenig aufgeräumt und sollte wieder Nachrichten empfangen können. Beste Grüße, Martin

Hallo Busch38, Ja, das ist meines Wissens so. Der SE Designer kann diesen Detailgrad in der Simulation, bis hinunter auf die Ströme und Spannungen der einzelnen Module, bzw. sogar Zellstränge nicht leisten. Derzeit leider nein. Ist aber ein guter Punkt, den wir mal mit SolarEdge besprechen sollten, danke für den Hinweis. Viele Grüße, Martin

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
