Hello,

 I have a question why I am getting different results of Shade Frequency?

Yesterday I’ve simulation results with higher digits (photo no.1). Today with same modules place I’m getting smaller values (photo no.2).

Please look at modules covered above. I think in second photo PV*SOL  not estimated shadows from the upper roof. But why it did yesterday?  

I’m really afraid that my previous projects were wrong calculated due to shading…

House:

Hello Vilmantas,

might you be so kind and send me the project files via private message here in the forum so we can have a look into it?

I hope this might be an issue with displaying wrong values. Do the yield values also differ after the simulation?

Kind regards,
Frederik

Hello

I have sent the project via PM. 

I ran out of time to reach the yield value. The next day I did a new (same) design and got diffent shading.

Best regards,

Vilmantas

 

Hi Vilmantas,

thank you for your project!

We have to check further things before I can give you a definitive answer!

Kind regards,
Frederik

Hi Vilmantas,

unfortunately there is a bug in the calculation and displaying of the shading frequency values for the modules. Thank you for reporting it! It is possible to move the mounting surface (blue framed area) to arbitrary positions only limited by the surface it is positioned on:

Even small shifts can be responsible for great differences.

I tested it extensively. IMPORTANT: This does not affect the yield simulation! Which means, your screenshots for showing the shading frequency might be affected, but not the overall yield simulation of your projects.

We did forward this issue to our 3D developer.

If you have further questions, feel free to ask!

Kind regards,
Frederik
