I had the pleasure of working with CalSolar as a drone specialist on about 30 of their projects across California. I was impressed by the design and layouts of many of the installs, very clean and futuristic especially from an aerial perspective. I would highly recommend CalSolar to any residential or commercial client looking for top notch design. I attached a picture from one of the more impressive installs in San Francisco.
