Total professionals from start to finish. Every aspect of the project was managed with attention to detail, each step in the process was clearly explained, and the project was comepleted on schedule. TFS also goes the extra mile after construction is complete. They provide hands -on training of the features of the product and accompanying software to make sure the owner is comfortable with the features of their new system.

TFS is a great business to work with. They communicate every step of the process, answer every question, and get answers for anything they don't know. Our installation had one issue that required research, and they kept on it until they got it worked out. They only supply first-rate equipment and I think they will be around a long time to support it. All the technicians were friendly, professional, and extremely competent. I have no reservations at all recommending them for solar installations.

Technicians for Sustainability is top notch. I have had ZERO issues with my system (panels and powerwall) since TFS installed it eight months ago. I couldn’t be happier! TFS made it easy. Throughout the process, TFS kept me informed and advised and prepared me for the next step. The staff was professional, thorough, and courteous. In fact, the entire TFS team was just so nice and very pleasant to work with. You cannot go wrong by choosing Technicians for Sustainability for your solar installation.

My expectations for quality planning and workmanship are rarely met, but TFS did not disappoint! From the first meeting with them through the completion of the project, I can't think of anything that could have been improved. They were also patient with me - one of those annoying customers who wants to have their hands in everything - during the whole process. I can't imagine anyone doing better than TFS. If you're looking for solar or energy storage in Tucson, look no further.

TFS is the best and come highly recommended. When the cost of getting solar was less than our TEP bill I shopped around. I asked my friends with rooftop panels about their solar experience and I was repeatedly directed to TFS, Technicians For Sustainability. I decided to wander into their workspace to learn what I could about this unique worker-ownedcompany that had a terrific reputation. When I walked in I was greeted by gracious Derek working at his computer near the entrance. Behind him I saw one of my decades-old newspaper editorial cartoons about solar power on the back wall of the office. A good sign. 10,000 suns ago I drew that cartoon of a witless soul carrying an appliance and a cord with a male plug on the end of it looking for “someplace to plug this thing in” and the dear human is oblivious to the gift above, the sun, of course, rendered with an electrical outlet waiting to be tapped. TFS were reassuring, patient and good humored as they offered us clarity, affordability, an easy to navigate--with their gracious assist--guide to the step-by-step process and best of all: magic. The day TFS guided us through christening our system by turning it on was an unforgettable moment of magic as power surged into our hacienda powered by light from the nearest star. This normally stoic old bird entered a state of wonder at the scientific marvel that was finally ours. Thank you, TFS--your staff, your field crews, and everyone there-- for making our transition into the modern age a joyful experience.

Great company to work with
We contracted w/ TFS at the end of 2019. Then the pandemic hit and we weren't sure what was going to happen to our business. TFS was willing to put the solar installation on hold until we were ready, no pressure to move forward. We eventually got back on track and had our solar installed. It works great! Our electric bill last month (July) was $18.

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.

Great work
TFS has done a great job for me installing solar. Actually twice! A few years ago before I moved, and just recently at my new home. After the first install, I knew I wouldn’t have used anyone else. They are trustworthy, professional, and know what they are doing!

Very professional and personable.
TFS as a team was impressive. Tamarack communicated to us the different phases of the project which was very helpful in organizing our schedule. Mike and the other technicians completed the install efficiently with little disruption to our daily routine. Steve connected the monitoring unit and showed us how to monitor the system on our phone in an easy to follow manner. All in all we are very pleased with the service TFS provided.

Great service and product with 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!

Very happy with TFS!
We chose this company after talking with several others, largely because of the clear presentation of system and payment options. Once we got started, all aspects of the process went smoothly and communication was consistently excellent, in spite of logistical challenges from the Covid-19 pandemic. Everyone who came to our house wore masks (well before they were mandated) and most communication was done by phone and email. Our solar system is working splendidly and we are very happy to have guilt-free air conditioning during this ferocious summer!

TFS is an amazing company.
TFS put our system in just a little over a year ago. We were so delighted with them at that time and still are. Recently, we noticed that we were not generating solar like we normally do. Upon looking at our layout on our app we saw one whole section of panels were not doing anything. We called TFS only to find out that they were already aware of it and working on the problem. Within two days, they were out and putting in a new invertor at NO cost to us. John, who came out could not have been more knowledgeable and efficient. He spent time answering all our questions (probably dumb ones). This company is so personable and professional. Everyone of them that we have talked with either on the phone or in person has made us feel that they totally care and love their jobs. We know people that are so unhappy with the solar company that did theirs. They get no answers to their questions and rarely even get a return call. Too bad they didn’t go with TSF because that’s not how they treat their customers. Thank you TSF for caring!

Highly Recommended!
I highly recommend Technicians for Sustainability (TFS) in Tucson as your Solar Installation company. They had very professional crews, work was done right the first time, and the areas cleaned up. At the initial meeting we appreciated the ability to real-time compare different number of panels to cover the peak-usage without detriment to the pay-back period. We are very happy with the PV systems with SunPower panels.

Job well done.
They talked me through the whole process and quickly and comprehensively answered all the questions I had. They took care of everything and there was great communication throughout the process, too. Really took all the complexity out of the process. Then, when the second progress payment was due, I was out of the country for a few weeks and couldn't immediately send a check. According to the contract they wouldn't have continued with the work till I paid but after explaining the situation they continued anyway without any more questions (I really didn't expect or even ask them to). After the installation it took only a few days to have the inspection done (they took care of this, too) and have the system up and running. My neighbor had Solar installed last month from a different company (against my recommendation) and they had to wait almost a month for the inspection. After everything was complete, they checked back a few times to see if I had any problems (I didn't). I had noticed a few minor air pockets under the coating they had put around the stands of the panels, nothing serious and I wouldn't even have mentioned it, but as they asked, I pointed it out. They came out to fix those and in the process completed some coating on a different part of the roof where I had done some unrelated work but hadn't been able to finish, yet. Oh, and the online monitoring is way more interesting to watch than it's supposed to be!

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.

Best choice for solar
We found TFS by doing extensive research on solar companies. We chose them because they are a local Tucson company with impeccable reviews. From the first visit from David through the install and final visit TFS handled everything perfectly! We couldn't be happier with our choice and would highly recommend them if you are going solar. They are honest, knowledgeable, timely and have very competitive pricing.

Best experience with solar install by TFS
We had solar installed by Technicians For Sustainability this summer and they were the greatest team to work with. The TFS staff definitely walk the talk and made the installation and education process as easy as possible for us. We've always wanted to use solar to do our part to help the environment. With the information shared with us by TFS, we feel like we know so much more now about why solar is such a good option and we're even happier to have chosen to go the solar route. The installation group led by Derek were incredible, keeping us informed every step of the way, working out creative ways to install the equipment in the best places, quietly going about their work, always smiling and offering a hello. Just the best group we've had working at our home since we moved to Tucson last year. We were also delighted with the others we worked with directly, Tamarack Little and Mike K. We so appreciated their excellent work and passion for their jobs and solar energy. We are grateful to have found TFS and look forward to working with them in the future with our current solar system and any future needs. They are a great part of Tucson.

Great experience!
I recently leased a SunPower PV system through Technicians For Sustainability, and am very pleased to now be producing solar power. I have worked in a similar trade for many years and know how difficult it is to assemble a team that is capable of successfully completing this process at a high level. I have been nothing but impressed with the entire TFS team. I am an attention to detail type of individual and TFS has surpassed my expectations. Every employee was professional, communication was timely and consistent, and PV system install was very clean. I highly recommend Technicians For Sustainability.

Entire staff from the time we called to schedule an appointment for an estimate to the time we had our "how to understand our Data Monitoring" was outstanding. All elements were explained clearly and had backup documentation. At no point did we feel pressured to buy anything. Excellent experience. We highly recommend TFS and will continue to support them.

Exceptional
Exceptional - that's the first word that comes to mind when we think of Technicians for Sustainability. They met and exceeded our expectations every step of the way. From proposal to installation - the TFS team is professional, responsive and helpful in navigating the path once we'd decided to go solar. Over the course of our installation each and every encounter with a member of the TFS team was pleasurable. We were excited to be working with experts in the industry, that really know their business, and are so well respected in the community.

I recently had my PV solar electric system installed in my home by TFS. This company did a fantastic job in explaining in great detail what I was buying, the permitting process, the installation, required inspections and data monitoring. Danielle, my designated POC for my project, kept me well informed each step along the way and she was a great help in getting me connected to the right folks at the the local utility company to get my system online. They are truly 5 Star professionals. George H. Marana, AZ

Best Contractor Ever
TFS installed both a solar water system and an electrical power system. In both cases they were by far the best contractor I ever dealt with in terms of professionalism, workmanship, reliability, value, and sincere interest in their customers' satisfaction. I am very handy with anything electrical and with plumbing. As such, I always think I would have done a better job than anyone I hire. Not so with TFS: they are what every contractor should be. And they are pleasant, too. During construction they had to add a concrete platform they had not included in their estimate, so they did it at no cost. One of the workers damaged something on the roof that I probably would not have noticed or attributed to them later, but they told me about it right away. They are uniquely professional. Finally, my systems have been operating since 2010 without a problem and outperforming design.

The Right Choice
When we decided that it was at last time to go solar, our first stop was the internet. During our exploration of various websites, we were struck by the clear commitment TFS employees share for sustainability and community involvement. Naturally, we contacted several companies for information and quotes, but we felt most confident about our choice to purchase solar after meeting with our TFS representative. Not only did he take the time to thoroughly educate us about photovoltaic systems and answer all of our questions, but his knowledge of all aspects of the process of going solar convinced us that TFS knows its business. In the end, while the competitive pricing made TFS a top candidate, what mattered most to us was choosing a local, mission-driven company whose members live into the values we, ourselves, strive to achieve as we look to lessen our impact on the environment we treasure. And we were not disappointed! Everyone at TFS is friendly, responsive, helpful, and competent. Our PV system was installed within weeks of placing our order, and while it took forever for the power company to do their part, TFS helped us navigate the process until our switch-over. We are operating, as promised, at net-zero! Thank you Technicians For Sustainability!!

Solar with Technicians for Sustainability
We recently had solar installed on our house, and we could not be more please with the work of TFS. David met with us and reviewed our options. We later received a proposal for installation. We never felt pressured or that TFS was recommending that we install a bigger system than what we needed. They did an analysis of the last year of our electrical use and recommended a system that would meet 98% of our needs. All of the TFS staff have been courtesy and patient when asked questions by non-technical people. The installation and follow-up went smoothly. Most of all I was impressed by the commitment of staff to alternative use of energy. They are all true believers. If you are considering a solar system you can't go wrong with this company. We felt they were ethical and professional.
