  2. Hi Frederik, Thank you very much for your help. :) I will give this a go and create a well optimized profile for the sunny hours and see how far i can take it :) I was hoping to achieve about 80 to 90% percent of Solar Fraction.....i know it's a bit ambitious :) Thank you Steven
  3. Hi Julius, I forwarded your request to our sales team. Best regards, Frederik

    license trasfer

    Hello, I want to ask if I can switch my license from my old computer without having a Software maintenance? Because I deactivated my license on my old computer and tried to activate on the new computer, and there was error because of expired Software maintenance on my license. I attached and photo. So my question is do I need to buy new software maintenance for switching my license to another computer?

  7. Hallo Frederik, danke für die Antwort. Wenn ich davon ausgehe, dass der Anstieg linear ist, dann dürfte der BYD HVS 12.8 in meiner Simulation nach etwa 18 Jahren auf 1.0 bzw. 100% Zyklembelastung sein. Ob die Leistungselektronik so lange hält, ist die zweite Frage. Was geschieht in einer PV*SOL-Simulation über 20 Jahre bei 100% Zyklenbelastung? Wird ohne Batterie weiter simuliert oder wird einfach immer die Restkapazität verwendet? Gruß Stefan
  8. Hallo RPK, die Abregelung bezieht sich auf die installierte DC-Leistung, also auch in diesem Fall auf die 44 kWp. Viele Grüße, Frederik
  9. Hi robin, at the moment this functionality is missing for tracking, since there are no geometrical time-dependent informations about the modules tracked. The interesting situations appear while sunrise and sunset. According to your low inclination angle of 17° I assume you are planning more equator-nearish, so the self shadow losses of the columns that might appear should be minimal (fast change of sun elevation). Is that correct? I'm afraid you should estimate this geometrically outside of PV*SOL. Best regards, Frederik
  10. Also, nehmen wir an, es soll AC-Seitig max 30 kVA eingespeist werden und wir planen 44 kWp aber überdimensionert mit nur 40 kVA WR-Leistung. Dann wie soll es sehen? Soll es auf 75% abgeregelt werden? oder wie oben beschrieben soll es auf die 44 kWp sich beziehen oder auf die WR-Leistung (in diesem Fall 40 kVA) ? Vielen Dank
  11. Hallo Stefan, die Zyklenbelastung der Batterie lässt sich einsehen, aber ja, leider nur für ein Jahr. Diese Zyklenbelastung wird linear skaliert. 100% Zyklenbelastung entspricht 80% maximale Restkapazität, woraus sich die Jahre ergeben, nach denen rein rechnerisch eine Batterie ersetzt werden müsste. Viele Grüße, Frederik
  12. Hi JOSE MANUEL, This value defines the price in case no other tariff is valid. You could e.g. define a feed-in-tariff for a period of 15 years. After this period the value for directly marketed electricity is taken. Best regards, Frederik
  13. Hi, I have a question. Is there a way to define the best row distance for a 1 axis vertical tracking system in PVSOl. The mounting angle would be around 17°, panel size 1x2M, portrait mounted.
  14. Hallo, auf Ihrer Hilfeseite beschreiben Sie unter "Zyklen, Lebensdauer", wie sich der State of Health (SOH) und die Lebensdauer von Bleibatterien berechnet. Zu Li-Ionen Batterien schreiben Sie hier: "Die normative Zyklenbelastung und Lebensdauer geht in die Simulation ein". Kann man in PV*SOL irgendwo den Verlauf des Gesundheitszustands und die Lebensdauer der Batterie sehen? Ich habe mir im Diagrammeditor eine Zeitreihe mit "Ladezustand (auf C10 bezogen)" und "Zyklenbelastung" konfiguriert, aber der maximale Zeitraum scheint 1 Jahr zu sein. 20 Jahre wären interessant. Da PV*SOL

    Hi pawel, the bankability is an exceedance probability for the energy yield. It is used as kind of a security measure for a finance provider like a bank. A bank is always interested in a high credit rating, i.e. in the case of large photovoltaic plants, in being sure that the debt will be repaid. Therefore this parameter does only make sense as a higher value than default. Higher P value means a higher probability for a lower but guaranteed (more probable) energy yield. You could of course set P to a lower value, but in our context as a planning tool it does not make sense to lower the de
  16. Can anyone please explain what the "price for directly marketed electricity" represents? I am designing a few sites in Spain and Portugal and this would be the only piece of information I am not sure about. Thank you very much.

    Hi Is there possibility to set probability lower than p50 for example p25? When i try to do this there is info: "Value should be between 50 and 100"
  18. Hi Frederik Of course, my question is the following: What does the program refer to with quantity of Systems? (see picture 1). And my interpretation is that each system obeys to a line that originates from the reserve tank and circulates through a certain amount of solar collectors (see picture 2).
  19. Hello, thank you for your attention. First of all I refer to the collectors as the solar energy collection panels. On the other hand, my question arises from the results obtained in different variables, done: keeping a number of systems (2), I am adding, in different variables, more collectors (panels) (20, 40, 80 and 162). For variable 1 (20 collectors) the energy given to the hot water system is 19443,44 kWh/year, for variable 2 (40 collectors) the energy given is 25675,71 kWh/year, then the energy starts to be lower! in variable 3 (80 collectors) 22579,54 kWh/year are given an
  20. Hi Rohan, welcome to the forum and thanks for your request. You could calculate the energy amount by 120kW * 24h *365 = 1,051,200 kWh. With this energy amount you could create a load profile at the page consumption: If you have a lower average load and 120kW as peak load as you wrote (120kWp), then you might calculate with a lower value and set the values accordingly to reach a higher peak load. I hope this clarifies your question. If you have further questions, please feel free to ask. Best regards, Frederik
  21. Hi SolarStevo, load profiles is a tough topic because of many unknowns. I just created a project with a custom load profile respecting a certain higher load from 8 am until 6 pm on workdays and a relatively low load for the weekend. In the summer at noon there is also a little higher load due to cooling. This resulted in a higher solar fraction since load and solar energy overlap more often. The solar fraction gets higher: Of course there is a limit, but I guess this clarifies the common question of getting a higher solar fraction. So did you manage to edit the
  22. Hallo Dexter, ich denke die Hardware ist mehr als ausreichend. Ein Blick in die Historie: PV*SOL 3D ist in seinem derzeitigen Zustand sehr betagt. Viele programmiertechnische Designentscheidungen sind aus damaliger Sicht nicht für solch große Anlagen gefällt worden. Viele Dinge unter der Haube können nur schwer geändert werden bzw. wir sind an einem Punkt, an dem das jetzige 3D auslaufen wird. Der einzige Rat, den ich zur Zeit geben kann, ist die Projekte so gut es geht zu vereinfachen. Ich weiß, dass das keine befriedigende Antwort ist. So ist der derzeitige Stand. Wir arbeiten mit
  23. Hi Jan Mackovic, additionally to my answer as private message I want to point at the very bad low light performance of the CIS module. We allow manufacturers to put their low light data even in case the performance drops i.e. the values are probably wrong. You could use our PV*SOL model for CIS modules, which is way better than the manufacturers values but still a conservative value which usually slightly underestimates the real performance. For being able to adapt this you have to copy the module in the database dialogue. Best regards, Frederik

  25. Hello Oliver Stojchevski, welcome to the forum and thank you for your request. Unfortunately not. We have been in contact with https://meteonorm.com/ for quite a long time now since their compilation of data has changed with version 8. That is why we need to adapt our internal tool MeteoSyn to those changes in order to work correctly with PV*SOL. As long as our questions are unsettled we cannot provide those current data to our customers. One reason is deviations that we cannot yet explain. The input irradiation data is of the most important concern for us and we hope that our q
  26. Hi Santiago Fondoso, I'm afraid I might need a little bit more information. Could you provide a screenshot to illustrate your point? Best regards, Frederik
  27. Hi Santiago Fondoso, welcome and thank you for your request. Could you specify your question? What do you mean by collectors? Best regards, Frederik
