  1. Great, thanks for the update. I will chase both too. it would be a shame to miss the next update. While we are talking about updates - when is PVSOL 2020 due? I'm always excited to see what's new. James
  2. Hi PVSOL team, I have been chasing Trina and Solis through a distributor to get the Trina TSM-335DE06M.08(II) and Solis 5G inverter range updated with you. Trina tell me they sent the data some time ago, no response from Solis yet. Could you tell me if they will be in the next database update and when the update is due? Many thanks James

    1. More control when drawing lines: snap to 10cm or input to drive line length 2. Snap to mid point of line - the ridge of a roof is almost always in the middle 3. ctrl+Z to undo 4. better control when rotating the camera position 5. Higher resolution on panels when zoomed out 6. Default project image zoomed out enough to show whole array Keep up the good work PVSOL team.
  4. @Etinergy You can't do a genuinely curved roof in PV*SOL. You need to have multiple buildings with a single pitched roof. The other way is to model it in Sketchup then import it. If you are using Sketchup I would suggest you flatten sections with the width of 1 or 2 panels. If you import a curved roof I think PV*SOL will approximate it with multiple flat sections but you will end up with gaps between panels. It is quite hard work but you end up with something quite impressive. Good luck.
  5. Just to finish this off - the project is now complete. Drone image courtesy of Perfect Sense Energy. What a beauty!
  6. It is great to see some new maps available. Getting clearer and more up to date maps will save time on designs and produce better images. I am always a bit nervous with an update but this was a great start to my day. Thanks James
  7. Hi, I have re-run a project and seen a large change in losses. It has all been a bit confusing but I will try to explain. 1. original - run on R7 Module independent shading = 0% Reflection on the Module Interface = -2.95% 2. Re-run on R8 - no changes to building or shading objects, global radiation the same as before. Module independent shading = -2.00% Reflection on the Module Interface = -3.54% 3. Moved nearby buidling then relocated building in place, re-run on R8 Module independent shading = 0% Reflection on the Module Interface = -0.74% Let me know who to send the files over to and I will send the original and new files. It is important for us to be able to justify changes to yield so it would be great if you could help me understand. Thanks James
  8. Hi PVSol team. I have 2 issues I need your help with. I will put them on seperate posts to keep things simple. Starting with the easy one - Can you explain why we have this problem again? There is nothing obvious in the release notes to explain. It isn't a major problem as the yield hasn't change on any projects I have re-run. It is annoying however to have to re-enter the location and the specific cable details especially on projects with lots of inverters. Thanks James
  9. Yes! About 4 hours on the SketchUp imported version and 2 hours on the PVSOL only version. The PVSOL version I spent more time working out the height of each building in Excel than building it.
  10. Thanks for the reply. As we are working on funded projects we avoid user created records. We will wait for the updated modules. Any help you can give to chase Trina would be great.
  11. As it's Friday I thought it would be nice to share an interesting PVSOL challenge and 2 solutions. I am working on a curved building with a curved roof. solution 1: modelled in SketchUp with measured flat sections on roof to place panels - this looks pretty but took ages to get curved roof to meet curved walls. Solution 2: built in PVSOL 3D design, multiple 2m wide single pitch buildings (lots of trigonometry) - this will be more flexible for small adjustments in roof pitch.
  12. Hi PVSOL team. I have a couple of projects with new Trina modules (TSM‐285-PD05 and TSM-280PE05H). Is there anyone at Trina you can chase for this? I have emailed the request to database@valentin-software.com and asked our distributor to get on the case but no luck so far. I know Chinese new year probably isn't helping. Thanks James
  13. This would be really helpful. Also snapping to a grid (10cm?) or snapping to end-points and mid-points.
  14. 2nd that! undo would be very helpful.
  15. The PV*Sol guys may have a smarter way but I think you will need to set up 2 buildings (1 for East facing roof, 1 for West). Give each a single pitch roof and work out the gutter height and roof pitch so that the buildings meet at the ridge. Hope that helps. James
