Difference between Unlimited sheds in Orientation and in Near Shadings

[Oscar Aviles]

Hello everyone,

I am writing you in order to clarify something that I am missing right now.

I first when to orientation management to try to check the optimization for my sheds with a tilt angle of 30º and 1º azimuth and 4 meters pitch. There, I thought that the Sensitive width would correspond to my panel length (one of 2.33 meters).

In my case I am using in the 3D scene sheds of 2 modules in height so in total, that sensitive width would correspond to around 4.7 meters  (2*2.33 plus 0.04 of inactive band).

However, when I put the value, it proved that it should be wrong:

 

 

So, I decided to go to the 3D shading scene and directly create my arrow of panels to try to discover what this width corresponded to.

As you can see, this would be the limit angle and the GCR for such panels and such pitch:

 

Looking at this, I thought that the heigh in the sensitive area above could be the widht introduced in the orientation , so I went back and introduced it:

 

 

Looking at the Shading limit angle and the GCR it could be approximately (it is not exact) what the sensitive width stands for. However, this arises the question: is there not a way of knowing beforehand the sensitive widht? Do have I to go to the 3d shading to know this parameter and then enter it in the orientation management? Iam interested in the shading graph and the show optimization.

I also though that it could be calculated with the sin30º or the cos30º with a hypotenuse of 4.7 meters (the length of the two panels in the shed). However, the closest value would be 2.35 meters (y) which also doesnt correspond to 2.29 meters...

Hope I explained myself correctly.

 

Thank you very much in advance.

Dear Oscar

 

First of all, in the "unlimited shed" orientation, the sensitive width is the total width of the modules aligned on your PV table.

For example, if your PV module is positioned in landscape in your 3D scene, the smaller side is 1.134 meters. Since you want two rows placed one above the other in each table (still in landscape), you need to multiply the smaller length by 2:
1.134 × 2 = 2.268 meters.

In my example below, I used 2 meters as the sensitive width.

You can always verify in the 3D scene whether the sensitive width value is correct. But if you already know the dimensions of your PV module, its orientation (landscape or portrait), and the number of rows per table, you can calculate the sensitive width.

You can also click on the "Help" button in the "Show Optimization" window — it will open a help page with a full explanation (see below).

If you need more information or something isn’t clear, don’t hesitate to reach out to us.
