  4. Hi Math, sorry for the late answer - I was a bit irritated as well, as the usual uninstall option seemed to have disappeared.. but then a colleague pointed me to the solution: You have to use the "old" version of the WIndows system settings feature to remove or change programs: Click on "Programs and features", search for PhotoPlan in the list, right click and select "Change". Dialogs will appear that let you uninstall PhotoPlan. Good luck, and kind regards, Martin
  5. Hallo Simon, sorry für die späte Antwort - deine Frage ist irgendwie untergegangen. Den Dachüberstand kann man ganz gut für alle vier Seiten einstellen, indem man den Haken "Gegenüberliegende Dachflächen gemeinsam editieren" rausnimmt, und dann für jede Dachfläche nur den Wert für die Trauf-Überstände eingibt: Beste Grüße, Martin
  6. Hi Burak, 2 MWp is really already a very large system, with about 6000 to 10000 modules depending on their power. If you use the 3D environment to design the system, PV*SOL might bring your computer to the edge of its power. Also note that PV*SOL is (still) a 32bit application, so there is a RAM limit of about 1.2 to 1.3 GB set by the operating system (Windows). This is - amongst other things - what limits PV*SOL in its capabilities. But good news is that we optimized RAM usage especially for roof top or open area mounting systems in the next release of PV*SOL premium (2020 R10), wh
  7. Dear Hugo, thank you for the input. We already have this feature request on our list. For very regular time shifts by 15 minutes you could use this feature here: But we know that this doesn't cover every tariff design (like yours for example). In order to estimate the cost effects of the 15 time shift, you could simulate it once with 0 minutes shift, and once again with 15 minutes. This should give you an idea of how the economics will behave. Kind regards, Martin
  8. Hey Miguel, the lifetime of the batteres is influenced by two effects: cycle loads and time. So there are the "cyclic lifetime" and the "calendar lifetime", the first of which we can calculate, and the second is more a number that is given by the manufacturer (determined by tests). The calculation of the cyclic lifetime is described here (at the end of that page, applies also for li ion batteries: https://help.valentin-software.com/pvsol/2020/calculation/battery-systems/lead-acid-batteries/ According the standards, we consider a battery as "dead" when it has reached 80% of
  9. Hi Joao, that is correct, our simulation core doesn't support simultaneous DC and AC coupling modes. We have it on our list but we can't give a scheduled date for that feature, I am afraid. In fact, there are a plenty of device topologies and most of all energy management algorithms implemented in battery systems available on the market that we are not able to reproduce in our simulation core. As you pointed out, the topology of a system, but also the management algorithms can heavily influence the energy flow through the system. We are aware of that and as I mentioned, we have that
  10. Hey People, I was trying to do simulation and the system size is around 2 MWp. But when I try to save or run the simulation, I get a failure as " An error occurred in the application." Can you please tell me what is the problem with that? I am doing simulation in deskto-pc and my ram is 16 GB with CPU AMD Ryzen 3 3200G with Radeon Vega Graphics 3.60 GHz.
  11. Hi Miguel, To my knowledge I haven't seen any option in PVSol to set the life-time of the battery. May be PVSol considers the degradation of the battery which inturn impacts the efficiency and eventually the energy that can be stored in the battery. -Vishnu
  12. Hi all, I'm designing a system with 2 inverters and one large battery, one of the inverters being a Fronius SYMO GEN24 10.0 Plus. The battery is connected to the GEN24 inverter, and the 2nd inverter is only acting as an extra AC power generator (AC coupling) to the main AC bus. One of the innovative features of the Fronius GEN24 is its ability to act both as a DC coupling (energy source is PV) and AC coupling (AC bus is source) simultaneously. This is key to our design, as the second inverter will provide for extra power to be injected into the battery, adding
  13. Thank you Martin, I would add another question, on the subject of batteries. What happens after the end of the lifetime of the battery,? Does the system stops taking the energy from the batteries into account?

  15. ps: die Quellenangaben zu den anderen Lastprofilen werden wir demnächst in der Hilfe beschreiben, danke fürs Drauf-Aufmerksam-Machen, dass da was fehlt. Viele Grüße, Martin
  16. Hallo Leman, in diesem Fall würden wir stark zur Nutzung der Lastprofile in der ersten Kategorie raten - Lastprofile aus Messwerten. Dort gibt es auch Lastprofile von der HTW Berlin und dem BDEW, die bestens dokumentiert sind: https://pvspeicher.htw-berlin.de/veroeffentlichungen/daten/lastprofile/ https://www.bdew.de/energie/standardlastprofile-strom/ Diese sind auch von der Auflösung her qualitativ höherwertig. Viele Grüße, Martin
  17. Hello, I've got some trouble uninstalling the software. I installed PV*sol premium and also PhotoPlan. Now I don't need it anymore and that's why I want to get rid of both programs. The normal way (Windows uninstaller) doesn't work for PhotoPlan and there's no unistall.exe in the installation folder. Does anybody have another solution? I will be very grateful for help.
  18. Hello everyone I'm a PVSOL Premium user and I've been trying to use it in the most complete way possible. I think the software has a lot to explore and can offer a complete analysis in some cases but it is not yet prepared for the Portuguese electricity tariff system. In our legislation the electricity prices are set for 15 min intervals and PVSOL is only prepared for hourly tariffs. It would be very helpful if you include the 15 min tariffs intervals in future updates so we can provide a complete analysis using only one software. I attached some images that show PVSOL vs Port
  19. Hi Alexander, es handelt sich bei dem Absturz nicht um ein Performance-Problem, sondern um einen (zum Glück seltenen) Fehler bei der Zuordnung von Modulen und deren Schatten in 3D zu den Wechselrichtern. Für neue Fragen gerne einen neuen Thread erstellen, so bleiben sie auch für andere besser auffindbar. Danke! Viele Grüße, Martin
  20. Hallo Martin, Danke für die Information. Dh. es liegt an der Performance der 3D-Simulation + Verschattungssimulation. Eine Frage hätte ich noch: Muss für eine andere Frage einen weiteren Post erstellen oder kann ich diese gleich in den Post stellen? MFG Alexander
  21. Hallo Alexander, schönes Projekt hast du da! Hoffentlich wird das auch so gebaut Der Grund für den Absturz der Simulation ist mit dem nächsten Release (2020 R10) behoben. Ich hoffe, das es in nicht allzu langer Zeit auf den Markt kommt. Beste Grüße, Martin
  22. @developer_mh I send you PM (have some trouble) please check if you can
  23. Hi Miguel, you can change the type of coupling in the battery system itself. Note that you can't change system database entries, you'll have to create your own, e.g. by copying an existing one: What I meant with connecting 3 equal DC coupled battery systems to 3 equal inverters is that. On the inverter page you have 3 times the same inverter: And then on the battery system page you'll have the battery system amount set to 3: Hope that clarifies the doubts. If you have questions, please let me know! Kind regards, Martin
  24. Hallo Martin, Im Anhang die PV*Sol-Datei. Ich hoffe das passt so. Anonymisiert sollte alles sein. MFG Alex Gunoldstraße PV v3.pvprj
  25. Thank you Martin, It does help, but then I have two more questions. I actually thought I had an AC coupled battery system. Is that possible? How to change from an AC to DC coupled system and vice-versa? Second, I don't understand how I can have 3x inverter conected to the DC battery system because I difined the battery system and the inverter in different tabs. Again, thank you, Miguel
  26. Hallo Stefan, guter Punkt, wir nehmen das mal auf. Danke und viele Grüße, Martin
  27. Hallo Alex, könntest du mir das Projekt mal schicken, dann kann ich schauen, woran es liegt und was man evtl. machen könnte. Gerne hier im Forum per privater Nachricht. Danke und viele Grüße, Martin
