Excellent work by excellent people.

Our experience with TFS has been so good from start to finish. They answered all our questions and made the process understandable. Every person we had contact with was friendly, knowledgeable and professional. If you’re considering a solar installation TFS is definitely the way to go.

Job well done

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.

Road block at the gate

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!

Green at last

My 10 panels were installed just over 6 months ago. TFS was a delight to work with, from planning, installation, and follow-up service. PV system is up and running, producing and saving as expected. Absolutely, would recommend TFS and would use again.

WOW! What a great solar installation company!

I repeat: Wow, is this company GREAT! Every single TFS person we dealt with from start to finish was competent, pleasant, and true to their word. Their willingness to tailor the PV system to our specific needs was awesome, and they take the time to inform the customer about what to expect at each step along the way. I recommend them as your solar installation company without reservation.
