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
