Shading Calculations On 3D Design

Hello,

 

I have developed my first design using 3D Design feature and so I am really not acquainted with this features on the report.

 

I did some tests and no matter what the spacing between rows I apply I always get the same "Yield reduction due to shading", in this case 16.3%, 

 

this parameter is calculated based on what?

 

My initial row spacing calculation was 1.64 m and effectively it had some partial shading on the pannels, shade frequency about 2.7%,

I have now increased the distance up to 4 meters, there is no shading on the pannels and I still get the same results.

 

I need to justify to the customer how this Yield reduction due to shading is calculated...

 

I look forward to hearing from you.

 

Best regards
