The first configuration was two rows of 10. Rather than waste time in 3D, I jumped to Photoshop. This allowed the second configuration to be created quickly.
This was the chosen configuration. The panels now sit in the real world based upon an informed decision through visual communication.
Original photo that I shot was not selling the idea of solar. Rain soaked stucco and clouds had to be 'shopped out.

solar residence - conceptual design

This quick Photoshop project was commissioned by Medicine Hat College during their planning phase for a modest solar project.
A photo on a rainy day was taken and converted to a sunny day with solar panels in two configurations. (see original photo)
