Rising energy costs was my motivation to invest in a solar energy system, "and add value to my property," so I scheduled a meeting with Craig, a salesperson for Quality First Home Improvement. He recommended I purchase ten panels, but after the installers re-measured, they suggested adding two more. I'm happy to tell you that since the installation my monthly PG&E bill has reduced substantially, "and everyone involved in this project was very caring, knowledgeable, and professional!"
