Quality First Home Improvement installed 17 solar panels for our home last December, and since then, we've seen a significant savings on our PG&E bill. We own a 3000 square foot home with a pool, so we were paying $400 each month, and now our bill has reduced to $50..."so we're extremely pleased!" The installers came and went so quickly, that the only proof we had that they were even here, was the 17 panels on our roof. This was our first experience working with Quality First, and we'll certainly contact them for future projects. Thanks Quality First for providing excellent customer service, and we've recommended your company to other homeowners!
