Orientation to Mounting Surface


Recommended Posts

Hello Valentin,


When selecting Solar Panels:

I wonder what the reason was to make the "Orientation to Mounting Surface" to make a degrees calculation based upon the longest wall. The fact that it is based upon the longest wall makes it more difficult to calculate and it is a fact that it takes more time because with commercial installations there are allmost more buildings in different directions. 


Can this be updated and make the "Orientation to Mounting Surface" one size that does not change?




Have a great day,

Hi Remu,

please correct me if I got your question wrong, but you don't have to calculate anything by hand if you want to place module mountings on flat roof tops. There is a dialog that helps you to get the inclination and orientation of the PV modules that you want:




Then the program will determine the orientation to the mounting surface and enter the values accordingly:


Hope that helps, kind regards,
