    Dear helpers, please help me to understand when / where the CABLE PLAN option designs is available! Could you please check what is wrong here? As I only have one building with flat roof top plus one module type and one inverter. Thx.

    Is it possible to rotate the panels 90 degrees from the position of the panels? The panels follow the building, but this will be a more north/south installation. the idea here is to rotate them 90 degrees to get east/west direction

  4. Hi, I may be in the wrong place here but after searching this site and the internet, I cannot find the settings that I need to add PV*Sol to my company's Intune portal. Is the documentation somewhere of the commands for installing, uninstalling and any special switches that can be used for unattended installation to a Windows 10 Pro device? Thanks in advance, Charles

    Is there any option to view the production forecast per day? Its easy to see per month the amount of kWh but it would be nice to have the option to see it per day.

    hi freinds, how to make connection cable with the micro-inverter ? the message is :" At least one PV module has a micro-inverter. these cannot be cabled in the current program version." i use the micro-inverter " enphase energy : IQ 08" what is the solution to connect all them or it is not necessary in this condition ?

    Hello PV-sol, For a new project a have to acquire values for p50 and p90. I've found this already: If I understand correctly, there should be a way to access a "Bankability: Exceedance probability of forecast yield" dialog from the financial analysis page. However on the financial analysis-page of my PV-sol 2018 PRO(screenshot attached) I see no way to enter the bankability dialog box. I am missing something? Hope to hear from you soon. Many thanks. Greetings, Ralph van Leeuwen

  9. Hello everyone, I have such a problem with the installation of 250kwp , I am trying to achieve self-sufficiency above 80% while I pull out a maximum of 62.5%. Of course, I introduce consumption in the form of a hall (I design a gym) where the consumption is 120000kwh per year. Despite combinations with changing the hours of operation of the hall, for example, from 10 am to 6 pm, nothing helps, I can not cope with this and it is important for our customer to see the real consumption. I want to add that the installation is without Battery ! Best regards and looking forward to advice

    Hello, I would like to know how I can create a 15-year graph in which I can see the annual production taking into account the losses due to the panels, inverter, etc... Thank you

  11. Hi PVsol team I hope to get your help. I have solar PV system on flat roof. I am facing a problem with the title angle and the pitch (Row distance). I tried to change the pitch and the tilt angle values but PVsol didn't change anything so always the tilt angle is 30 degrees and the row distance 1.982m. So I tried to increase the row distance value by increasing the value of "Row depth" but nothing has been changed in PVsol. How can I change the row distance "the pitch" and the tilt angle in PVsol?

    Hi, How can I display the characteristic curves for a grid-connected project? When I select characteristics curves in the diagram editor, I obtain the message: "No characteristic curves available. Please activate recording of characteristic curves in Program Options". I have selected: "Record characteristic curves for modules/All" in Options/Project Options/Simulations. However, I still cannot see the characteristic curves. Is there anything else I must do to obtain the characteristic curves? Thank you.

    Hello, Please help in an on-grid photovoltaic system, how can I allocate parallel batteries to each inverter? I found the option to allocate to only one inverter in the system and I want to allocate for 2 inverters and 1 inverter without battery thank you

    Is it possible to extract climate data only for one specific year? I have chosen the location and I get data series for 1996-2015 but I only need it for the year 2004. I can't find any data for this year on the internet so it means I can't even import it in PVSOL.

    Hello, so i have a problem where when i want to add an inverter to the configuration it says the following: I have 5 module areas, and 4 of them are just fine but the fifth one says this error. I tried to add more or less configured modules but it doesn't help. Any ideas? Thanks, Bojan

    Hi! When I am investigating the financial analysis of a photovoltaic system with an electric vehicle, I realize that the tariff for the energy generated is only considered when the system charges simultaneously with the operation of the generator (operation during the day). If I select to charge this vehicle at night, the calculation system considers the value of the local utility's energy tariff, but without considering that the value used for this may come from the credits generated by the injected energy (Surplus Feed-in ). Is there a way to adjust any parameters to adapt this analysis?

  20. If I use hybrid PV solution (SUN2000-8KTL-M1) with batteries (LUNA2000-15-S0) and the batteries has lower charging/discharging power (5kW) as charging power of EV (11kW), system dont work correctly. During no PV production the full charged batteries dont support a load and EV consumption (all power flow from grid). When the EV is disconnect the batteries start to discharge energy to standard load. Correctly a fully charged battery should supply power (although partially, until its nominal power) to the EV device even after the sunlight is lost.

    Morning, I hope this message finds you well. I've been working on modelling a solar PV system with a battery, and I've identified that Growat WIT-100K Hybrid inverter are not currently available in the software. I have attached the datasheets for the components in question. Could you kindly add them to the PVsol model? Y Thank you for your attention, and I look forward to your prompt response.
