I suggest you find a CAD solution. You can study the shading at specific times and some programs will animate.

The roof slopes are 18 degrees. The tops and bottoms of the modules will follow the slope of the roof. There will be 3 rows of modules. I have heard that the shading is different in this scenario, that the shadows will be triangular and perhaps longer. How can the shading be calculated with this arrangement? Is there a rule of thumb to follow other than the normal of three times the height difference? Thanks, Drake
