I have been trying to visualize the sunpath shading for a vertical PV surface. The PhotovolaticSurface component seems to be working properly and outputting a reasonable value for ACenergyPerYear… however, I can’t get the shading visualization to show up under the SunpathShading component. The surface normal is correct. It works fine with a horizontal surface - has anyone else discovered this problem and been able to make it work?
I attached a couple screen shots of what the sunpathshading looks like with a vertical and horizontal PV surface.
Outputs, AC Energy per year (I tested a very small surface which is why the value is so low)
