Technicians for Sustainability Reviews

I am extremely pleased with my solar system from TFS. It has significantly lowered my energy costs this summer. I referred a neighbor who also installed a system from TFS. They are committed to green energy and are a pleasure to work with .

Friends and neighbors strongly recommended TFS to us when we began considering installing solar. Although we had an opportunity to use another company through a solar installation coop, we elected to go with TFS because of their excellent reputation, and could not have been more pleased with the outcome. Communications with TFS were excellent, as were all aspects of design, installation, and operation. They are extremely responsive to all inquiries, and our system has been great–we’ve had negative or $0 utility bills for the past 3 months!

These guys are competent, thorough, fast and smart. They delivered everything they promised and more. The cost of doing nothing to your house and buying unlimited electricity from corrupt utility at extortion level pricing will just go up up up so do what you can while you can: put TFS solar on your house.

It was such a pleasure to work with TSF Solar. Tamarack Little and his team are professional, courteous, knowledgeable, and punctual. What I appreciated the most was to be kept appraised of their progress every step of the way. I can’t say enough good things about them. Highly recommend.

I cannot say enough positive things about TFS. I have heard their commercials on public radio for years. I have several friends who have used them for solar installation on their homes. For me, it was a no brainer as to whom to call when I began to explore solar for our home.

From the beginning the process was very smooth. I was provided with ample opportunity to have my questions addressed. After we decided to go forward with the project it was smooth sailing from the get-go. We were expecting to have our system installed by March of 2024 after signing a contract in late August. By December, TFS offered us the opportunity to begin our project early.

Throughout the entire project, we were kept up to date on the schedule and process. When weather delayed an element of the installation, we were informed and promptly re-scheduled. In the end, the project was completed two months before we had been originally told it would be. And, I should add that TFS interacted with TEP throughout the process. So, all of that interfacing was handled for us by TFS. And, all of the crew members who worked at our house were friendly, professional, timely, and respectful of our property and time.

Bottom line for the system is that we are now generating electricity such that our TEP bills have largely been made up of fees that are charged by TEP.

Do yourself a favor, meet with TFS to discuss your project. You will not be sorry that you did.

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.

The best of the best. All contacts with all staff were ultra professional ❗️

Technicians For Sustainability was highly recommended by friends and others who had solar installed on their homes. We had solar installed on our previous home and loved it but had difficulty finding honest and reliable service when needed. TFS was incredibly knowledgeable, profession, and up front about the installation process, cost, and benefits of their services and worked closely with us in planning our system. They guided us though the installation process and gave us advice and options as they installed the system. Our system is up and running great and we can monitor the whole system from our computer and contact them if we see an issue. We love the fact that TFS is a Tucson based employee owned company and every employee we talked with had nothing but positive feedback about working for them. We would highly recommend TFS for anyone thing of having solar installed on their home.

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.

I can’t say enough positive things about my TFS experience. Total transparency and professionalism throughout the process, from pricing & finance options to design, permitting & installation, I felt like I was working with a true partner. All install work was very high quality, and support after install has been outstanding. If you are considering solar, TFS should be your first call.

We were referred to TFS by a friend who had done extensive research into solar companies in Tucson. TFS was his number one recommendation and we therefore selected them for our project and could not have been more pleased with the results.

From our first contact about the installation, all of the TFS team members were professional, knowledgeable and courteous. They explained in detail the process for an installation and guided us, to include working with our HOA as well as TEP to obtain their approvals. When any date and time was coordinated whether it was for the initial survey, installation, inspections by TEP and TFS, they were without fail always on time. Throughout the entire process they responded quickly to all of our questions. Their web page is well organized and full of valuable information as well. We have been using our solar system, consisting of solar panels and batteries since mid-March 2024 and have been very pleased with our system and the support we continue to have from all the personnel at TFS. Whether it be the bookkeeping, engineering, installation, or the inspection members, TFS has a great team that represents them in our community. Wanted to also give a special thanks to Mr Tamarack Little and Mr Max Barrezueta who have been our main points of contact from the start.

Overall, we have been extremely satisfied with the entire process. TFS is a great company and we highly recommend them to anyone interested in a solar installation.

This is the second time we’ve done a solar project with TFS and it’s been great both times. Very easy to work with, very communicative, friendly people, and quality work.

Great experience! They communicated everything clearly. The installation was professional and well done!

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.

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!

We have been enjoying our low or $0 electric bills this summer. We are very glad we got solar. TFS did a great job explaining our options and how solar power would work for us. Installation went smoothly. Panels are visually unobtrusive. We highly recommend TFS.

This is our second project with TFS and I continue to be impressed by the level of professionalism with every member of their team. When Tucson Electric Power came out to connect the service their technician told me that of all the local installers that TFS is the best. I highly recommend them for anyone considering solar power.

It is without reservation that we would recommend TFS if you are considering rooftop solar. They are thorough and professional, and communication throughout the entire process was timely and clear. When you launch into a project like this, you want to know you are working with a quality organization. We, and others in our neighborhood that have worked with them agree, TFS is the kind of company you always hope to find.

From start to finish our experience with TFS was outstanding. They kept us informed, their technicians were professional. They monitored their work, and ensured everything was set up correctly. Our electric bill last month was $17! We think they are the best.
