Hi, I have a large, unlimited shed array with a billboard near it. I would like to incorporate the billboard into my shading analysis. It appears that the best approach would be the "definition by the orientation parameter shed option", though there is no step-by-step process to implement this in the help section. As directed, I have defined my tilt, az, pitch, etc. in the "orientation" section. I am using "unlimited sheds". In the Near Shadings section, I have created a horizontal polygon plane. I also created a triangular prism object. So, I have (1) PV field and (1) object. Now what? My shading animation doesn't show the shading from the object move across the PV Field. When I go to tools --> check scene validity, I am told "no shading field defined". I don't think my shading scene construction is really doing anything. How does one define a shading field?

Thanks, I just emailed you the (confidential) image. The email just bounced, though. sylvain@pvsyst.com ? I haven’t had success with any image, though. The red line shows up when I hit apply, though I never do see the actual image.

Has anyone else had this issue? It seems like "image base width" should be the distance of the width of the image, but I can't understand why it should be different than the distance from x1->x2. I'm struggling to find definitions in the help section.

I am trying to import a ground image, and appear to be missing something fundamental. My image should be 877m wide. When I import, all I see is a red line. How do I view the image? Where is "image base width" defined in the help section?

I find that toggling the "enable shadow casting" feature for a near shading obstruction does not actually turn the object off. I have to delete the object in order to get the model to recompute.

Same. I tried using "Unlimited Horizontal Tracking" but I can't be sure that is a system using N-S axis trackign east to west. None of the other single axis tracking options allow me to input a pitch. Please advise.

I recently updated my software to V6.67. I've imported a .pan and .ond file for my panel and inverters, respectively. I go to project -> grid system definition and can find the module & inverter I'm looking for. I select them, pick my numbers of strings etc. and click ok. I even ran a simulation, no problem. The software is having a hard time retaining my component definitions, though. When I go to revise the configuration, I get the error message "No component available now on the market for this manufacturer" and it erases my previous selections. I have to re-select my module/inverter each time. If I don't reselect, and hit "cancel" exit out of the grid system definition window, my "system" button turns red and I get the following error: Error while reading hte PV module "xxxx.ond" : File not found You will have to define another one in "System" definitions! I open the definitions again and now I can't select my module; it said my module was invalid. So I close out and try to reopen, and now it's found the module exactly as I had defined it before. I'm not sure what's going on it's just being very buggy every time I try to open the grid system definition window to make any changes. Note, this started after I went through my detailed losses and made some changes to match my project specifics. Help!

How would one remove the P50-P90 simulation from the final report?

That was it! I was using NREL TMY3s, but changing that distance value in the preferences made my files available. Thank you!

Hi all, Is there a way to use TMY data at a user defined site? I have imported my TMY data, but I can't seem to make it available to my site. I can make a site specific to that TMY data, though I worry that the latitude is too far off from my actual site. Maybe it would be inappropriate to use TMY at a different site and it's not possible to do in PVsyst... advice?

Hi, Does anyone know the exact definition of the following: - Pitch (spacing plus height of the modules, or projection of such to the ground base on tilt?) - Coll. band width (height of the modules or projection to the ground based on tilt?) - Top/bottom inactive band - Ground area occupatino ratio, or A(coll) and A(ground). It seems this is not equivalent to "ground cover ratio", an NREL term, correct? GCR is a comparison of horizontal projections, whereas GAOR seems to compare lengths at different angles? Anyway, a graphic in the help section would be useful. I'm trying to guess based on the little graphic but it's hard to really tell. -Jen

Hi, I suggest more opportunities to save a project. For example, I started a project by defining a site and then attempted to create a variant. I had defined my orientation and most of my system when I realized my inverter type was not an option. I had to exit the variant to create my inverter. Or maybe I had to switch to a new task. Either way, I could not save the work I had started on this variant. When creating inverters and other components, I recommend a "save as" option. I am trying to enter an American version of an AE inverter, and it would be nice to be able to start with the European counterpart and adjust where there are differences. -Jen
