I use a CAD program for optimum Solar Panel Layout for the challenging buildings in the StLouis Region. This allows me to remove the Panels that are affected by Shading Issues. I then Place the CAD drawing onto a Google Earth Location and can provide a Clean Energy Output Report based on the location in relation to the Suns Position on the Location.
Step One Design the Building for Solar Array
Install Solar Modules ‘Notice Shading Area’
Remove Solar Panels Located in the Shaded Portions
Insert SketchUp CAD Design into Google Earth for
Clean Energy Production Report
