Technicians for Sustainability - Tucson, Arizona

TFS did a terrific job. They did a very thorough estimate and even took into account the shadow that would be cast by the giant saguaro. Other firms were more concerned about how many solar panels they could stick on the roof to increase the price. When we did a bid comparison the costs were almost the same but we got 2 Tesla battery storage units too, instead of just solar panels. They took into account all of our concerns. ALL of the TFS folks were extremely personable and professional. You could tell that they really cared, were dedicated to doing the best job possible, and were willing to work with us. The other major factor is that they are Tucson based and have a stake in our community. It was a pleasure doing business with them and we have absolutely no hesitation to recommend them for any work you need to have done.

TFS was great to work with and very responsive throughout the entire process. It has been a few months now since we got PTO, and the system has been working flawlessly. We only considered well established local installers, and we take comfort knowing they will be nearby should anything go wrong.

TFS was an amazing experience after a nightmare experience with another solar company. No hard pressure sales and very professional. My favorite thing, other than the awesome (ahead of schedule install), was that the final payment was not due until the system was online, inspected and approved.

They kept me informed all the way and the installation looks very professional down all of the repairs for wall penetrations, etc. Their own internal QA/QC is great, and it is comforting to know that they are here in town for support! Thanks TFS!

TFS recently installed a 10.32kW solar system on my roof, maximum permitted by Trico, and (2) Telsa Powerwall 3s totaling 27kWh of battery storage in my garage. The entire process from customer contact, design, permitting, installation and permission to operate went almost flawlessly. The back office and install teams were very professional, on-time and pleasant to communicate with. In addition, the installation team demonstrated great pride in their workmanship, work area cleanliness, wire routing, panel mounting, etc and delivering a great final product to the customer.

My system has generated a little over 7500 kWh of solar from June thru Sept 2024, providing 78% of my total home energy needs so far. One of the system highlights was the seamless cut over from grid to battery during a recent outage event. The excellent Telsa energy app on my phone for monitoring, configuration and data viewing is one of the other excellent highlights of the system.

Great Experience with TFS. Estimates, planning, installation, startup and hands on training went off without a hitch. I would recommend TFS to anyone looking for a solar system for their home. The system is producing as expected and our power bills are less than expected. Thanks, TFS.

When we were researching solar companies, the vast majority of people we spoke with recommended TfS. We have been incredibly happy with our choice.
The TfS team walked us through every step of the process, answered all of our questions, and continue to support us now that we have been generating power from the sun for months.
All the people we interact/ed with are knowledgeable, professional, and friendly - from the office staff to the installation crew.
Also a bonus: You can nerd out using your solar app if you want to modify your personal usage behavior, or just follow the clear recommendations and guidelines they provide.
Regardless, if you are looking for a solar company who is Tucson based and awesome, we highly recommend Technicians for Sustainability!

TFS was recommended to us by a friend who had used them. We were thoroughly satisfied with how well the entire process went, from the intitial request for a qoute to the final system walkthrough. Staff and installers were responsive, knowledgable, friendly, and on time. Workmanship was clean and well executed. All steps and processes were well explained and no surprises occurred. Highly recommend this company if you are looking for a solar system installer.

Everyone we had contact with from Technicians for sustainability was very professional and easy to work with. They spent the time to make sure we understood how everything was going to happen before during and after after the install. Everything was on schedule from their side. I think TEP was slow on their final step but that is out of the installers hands. I highly recommend Technicians for Sustainability for all solar needs.
