  • "Job well done"

    Reviewed May 13, 2021

    Our solar installation experience was terrific. You all were responsive and on-time. You never left us guessing. Special kudos to Willy and his crew. They did a complex job efficiently and without any interference in our daily routine. They all seemed well organized, got along well with each other and enjoyed their work. Most importantly they installed the solar panels with minimal change to the appearance of our house and left the job site clean with nothing for us to pick up or restore.

    Call I called there multiple times to get a quote but they never return my calls nor sent me any emails tried to talk to somebody else but the person who answers the phone Laura won't let you speak with someone else so I'll just take my $20,000 elsewhere it's sad because I wanted to get someone in Tucson to do my job and they are an r e c accredited company but looks like them ending up using someone from Phoenix cuz I can't speak with anyone there

  • "Great service and product from TFS"

    I can't say enough good things about TFS and how they walked us through the process of getting solar installed for our home. We got a customized set up and they answered all of my detailed 'engineer brain' questions with ease.

    After the install I hopped up on the roof to inspect their work - I was impressed! And since the system was turned on it has been producing quite a lot of energy. It will be so nice when summer rolls around, to be helping our AC system keep us comfortable in a more sustainable way.

    I didn't realize just how much water and CO2 production will be avoided over the years by switching to solar, and how we are also helping our neighbors by sharing our excess clean energy.

    Thank you TFS!
