In order to install PVsyst silently, for example when deploying it remotely, you can use the following command line : PVsyst-7.4.0.31973-setup.exe /qn Just replace the EXE file name with the one you wish to install.

Hello, I am not sure this is something we can do with the forum engine. However here are two tips : When pasting the content you can use Ctrl+Shift+V to paste it and clear the formatting in the mean time When you want to add a carriage return, you can press Shift+Enter instead of Enter only to just add the new line and not a whole new paragraph I hope this will help !

Hello, The trial has all features and is lasting 30 days, after that the software will switch to DEMO mode where capabilites are very limited. During the trial there is also a watermark printed on the simulation report.

Hi julmou, You need to keep the Orientations management dialog opened, and then the menu items will be available. Maybe we should update the help topic to specify that one should not close it after step 1.

Solution #1 When PVsyst is starting Windows checks if it is coming from PVsyst SA to ensure that this is an authentic copy of the software. This should guarantee that PVsyst is virus and malware free. If this check is failing a pop up is displayed: "The application can not start because it is not signed by PVsyst SA." If you downloaded PVsyst from http://www.pvsyst.com, the error is probably appearing because you are using an old Windows, which does not contain our security partner's certificate. Please follow this procedure to update your Windows certificate list: - In Windows, start menu >> Control panel >> Add or remove program >> Add/Remove Windows component - check "Update Root certificates" - click OK. - then restart the computer. Solution #2 It looks like sometimes, asking Windows to update certificates is not enough: it does not install the correct certificates. The other solution is to install certificates manually. Here is the procedure. 1.Download these 2 certificates: - https://cacerts.digicert.com/DigiCertTrustedG4CodeSigningRSA4096SHA3842021CA1.crt - https://cacerts.digicert.com/DigiCertTrustedRootG4.crt 2. Install these 2 certificates, so for each of them: - Double click on it - "Install certificate" - "Next", "Next",... (keep the default options) until the end. Start PVsyst again. Solution #3 If you are using Windows 7 and still encountering this issue, the following may be useful. First of all, you need to be logged in as an Administrator on the computer. Download the two following certificates : https://cacerts.digicert.com/DigiCertTrustedG4CodeSigningRSA4096SHA3842021CA1.crt https://cacerts.digicert.com/DigiCertTrustedRootG4.crt For each certificate : 1. Double-click the file 2. Click on Install certificate 3. Click on Next 4. Select Place all certificates in the following store, click Browse, check Show physical stores, select Trusted publishers > Local computer 5. Click OK, click Next, click Terminate Try running PVsyst again, and if adding both certificates still doesn't fix it, try the following steps : 1. Click Start, click Start Search, type mmc, and then press ENTER. 2. On the File menu, click Add/Remove Snap-in. 3. Under Available snap-ins, click Local Group Policy Object Editor, click Add, select the computer whose local Group Policy object (GPO) you want to edit, and then click Finish. 4. Click OK. 4. In the console tree, go to Local Computer Policy, Computer Configuration, Windows Settings, Security Settings, and then click Public Key Policies. 5. Double-click Certificate Path Validation Settings, and then click the Stores tab. 6. Select the Define these policy settings check box. 7. Under Per user certificate stores, clear the Allow user trusted root CAs to be used to validate certificates and Allow users to trust peer trust certificates check boxes. 8. Under Root certificate stores, select the Enterprise and third-party certification authorities radio, and then click OK to apply the new settings. And then try to run PVsyst again.

Hello, Could you please give more details because the screenshots all show an orientation of 10°/43° which seems correct ?

Hello, I know this was a long time ago, but if you still have the issue please attach the DAE file that you are trying to import into PVsyst.

Hello, Please make sure that your computer and PVsyst are able to access the different URLs listed in this post : https://forum.pvsyst.com/topic/2524-web-services-for-all-pvsyst-functionalities From the error message, it seems like PVsyst can't load the map because it can't reach the server.

Hello, Does the MP4 file exist in the folder you selected ? If yes, then maybe there is no default video player set for reading MP4 files. If not, it can be an antivirus issue preventing PVsyst to write the files required to generate the video file. Try to disable your antivirus temporarily and generate the video again. We have been working on improving video generation for version 7.2.5, hopefully this will fix these antivirus issues.

Use PVsyst on a Microsoft Azure Virtual Machine WARNING : this will describe how to use PVsyst on an Azure Virtual Machine, which is different from Azure Virtual Desktop. Azure Virtual Dekstop is not suitable for PVsyst as it is running on a specific Windows version which is actually a Server version. To be able to use PVsyst on Azure VM you need to make sure that you attach a secondary hard drive to the VM because the OS harddisk ID will always change when rebooting the machine. So basically you can create a basic HDD (not even an SSD) of 32GB (minimum available size now) and attach it to the VM prior to activating PVsyst. If you already activated PVsyst on the machine, you need to contact our support in order to reset your license : https://www.pvsyst.com/contact/

Hello, You should be able to import trackers on a sloped terrain if you are using PVsyst 7.1. Make sure you update to 7.1.2 as we found out some special cases in which it was not possible to proceed to the simulation, and these have been fixed in this patch.

Hello, Trackers on a sloping terrain can now be done in PVsyst 7.1, either by : - placing tables by hand - filling a zone with trackers - importing such layout from DAE, 3DS or PVC files

Hello, As Daniel suggested maybe the best is to only model a part of the plant, or at least split it into several variants. Also, you can maybe group some tables together if the layout is regular, this will simplify geometry. I would suggest to remain below 10'000 tables (the lower the better) for PVsyst to handle it correctly.

Hello Michele, Thank you for all these improvement ideas. About the slow report generation, I couldn't find any mail from you about it, maybe you can try to host it somewhere and send us the link ? We put a lot of efforts answering to emails and if one of your mails gets no response then you should send us a reminder. Actually this forum is meant to be an FAQ as well as a space for PVsyst users to exchange or help each others. We do provide some support when we come around here, but the best you should expect is from emails. An additional note : the PVsyst license doesn't include technical support, we provide it for free and we try to help all users equally.

User interface and localization PVsyst now proposes a new completely overhauled user interface, harmonized throughout the whole software along with complete localization. Full-software translation coverage (except the Help), Turkish and Korean languages available. PVsyst is now sized and optimized for screens with a resolution of minimum 1280x720 at 100% text size. Support of 64-bit architectures Extends PVsyst capabilities of handling large projects and shading scenes System The restriction of 8 sub-arrays has been removed, you can now have an unlimited number of sub-arrays Shadings New conversion of fixed tables to trackers. Trackers with central gap parameter for bifacial, tracker distribution on a hill. Output AC circuit Definition of several MV and HV transformers, with their specifications Simulation, live results display Simulation result values and graphs update in real time while the simulation is running. Simulation errors and warning are now displayed with the results. Economic evaluation Levelized Cost of Energy (LCOE), Net Present Value (NPV), multiple loans of multiple types, advanced depreciation configuration. The economic evaluation is now availability for Stand-alone and Pumping systems. In the version 7, an update to the following models will have a limited impact on the yield compared to V6: Transposition model With the release of V7, PVsyst now proposes by default the new transposition that applies to both Hay and Perez models. This new transposition introduces an improved treatment of the circumsolar component. It will have impacts on the electrical shadings and vertical Bi-facial systems. Module layout The module layout has been extensively reworked with updated electrical shadings calculations that can handle half-cell modules.

Hello, We have identified the cause of the issue, it’s related to a recent Windows update, Could you please check on your computer if you have installed the below Windows update and if so please remove it. https://support.microsoft.com/en-us/help/4497165/kb4497165-intel-microcode-updates Unfortunately Microsoft does not give accurate information about the impact of this update. The only solution for now is to remove it to fix the 3D issue. Best regards,

Hello, just to give some update about this topic. With PVsyst 7 it is now possible to import trackers from Helios3D, we updated the H2P format in collaboration with the Helios3D team to make this possible. However, PVsyst still limits trackers scenes to have the same parameters for all trackers (tilt, axis angles, etc), we will allow irregular layouts in the future.

Hello ! We did not improve the report much for PVsyst 7.0 (only the Module Layout printing), but we will release big improvements for it in PVsyst 7.1. We plan to : - improve the layout for a better design and less overlaps, - use image files instead of re-calculating the 3D scene for the Shadings part, The default pages would also be a good improvement in my opinion, we'll see if we can make it happen too.

Hello, We don't really know how Skelion proceeds to export to PVsyst, it is using the H2P format which was initially designed to transfer data from Helios3D to PVsyst. It is possible to include geometry of objects which are not tables in the H2P format but I don't know if Skelion actually supports it. However if you are using Sketchup to design your system, we recommend that you use the direct export to DAE (Collada) already included in Sketchup. The only thing you need is to paint your PV faces with a material prior the export so that PVsyst will be able to identify them and create them correctly. Here's a simple example tutorial : The related help section in PVsyst documentation is : Project design > Shadings > Near Shadings: Import > Sketchup and other CAD software

Hello, We added this feature in PVsyst 6.7.7, on November 15, 2018, a little bit of time after your message :)

Hello, It is currently not possible to import trackers from Helios3D.

Hello, Thank you for reporting this with the results of your own tests. PVsyst being compiled in 32 bits is becoming an issue since the shading tools have evolved, the limitation was previously coming from the computation time and now it's the memory usage. We are aware of this, though compiling PVsyst in 64 bits is not very easy.

Hello, Far horizon is used to calculate the positions of the sun at which it gets hidden and therefore the PV production is stopped. About your shading scene problems, can you please make sure that your display drivers are up-to-date ? Here's a how-to :

Hello, Well you should be able to import the terrain data from both formats, but you won't get the textures for now. You can always import a ground image (File -> Import -> Import a ground image) and place it in your scene but it will remain flat.
