“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.”

“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 h”

“We now get our power from the SUN!!! Thanks to Technicians For Sustainability for helping make it so. We started the process late spring and worked with Max B who helped us determine our solar needs. From there, TFS staff was extremely helpful in guiding us through the whole process—from financing to how to understand our system and how to make the most of our solar. It really felt like everyone was invested in good customer service, which is likely because TFS is cooperatively owned and staff have a stake in TFS’s success. We discovered them through friends’ recommendations and now we’re part of that community of happy customers.”

“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.”

“This is the only company I will ever go with. Great communication and professionalism. Why lease out your roof to some unknown company when you can be the sole owner of your own electric company? I haven't used power from the grid in over a month. Go TFS! Update 17 June 2026: Tucson got hit with a powerful monsoon storm, which knocked down a bunch of power lines. My neighborhood was out of power for 5 hours and I didn't even know it, had it not been for the Tesla app alerting me that my house was being powered by the Powerwall batteries. It was so seamless that my oven clock did not blink like it usually does during an outage.”

“Really glad I found this solar provider! By selecting their solar lease option I was able to save about 25 to 30 percent as opposed to the purchase price. In addition they did the installation on time with absolutely no issues. A competent and friendly service from sales to installation. Highly recommend TFS Solar!”

“We had our first set of panels installed just over ten years ago. A few years after that we decided to prepare for getting an electric car so we installed more panels. Each time we chose to install more panels than we needed to provide extra power to the grid. (That was our idea, TFS did not pressure us to do that.) Both installations were done professionally by friendly, competent technicians. We chose TFS because of their ethical communication. Other companies told us how much money we’d save it TEP increased their rates by 4% each year. (Since TEP NEVER had an increase of that amount at that time, it was an inflated, dishonest amount.) TFS told us how much we’d save if TEP never had an increase. Since there will always be increases, that means we will save more than they projected. We”

“If you’re looking to make the leap to solar TFS is your best bet. From the get go these folks shot straight and answered all of our questions. They put us at ease and set up a system for us that met our specific needs. More than just a transaction we feel like we have a partner for the life of our system. They were professional and courteous at every step, and always arrived on time and prepared for every segment of the installation. We can’t recommend them highly enough!”

“I am on the Board of Directors of a very low income senior housing facility that was fortunate enough to win a grant from the City of Tucson, part of which was used to install a solar system. TFS employees Bethany and Rip were exceptional to work with - professional, communicative, responsive, and incredibly knowledgeable, and the installation was completed months before planned due to a fortunate circumstance. Their deep knowledge of the local utility requirements and governmental regulations was instrumental in helping us get the most out of our system and they and their teams' experience led to a highly successful early installation with no issues. I highly recommend TFS for any solar installation need and thank them for their hard work and dedication to sustainable power alternative”

“🌟 Review for Technicians for Sustainability (TFS) I recently had a solar system installed on my home by Technicians for Sustainability (TFS), and I couldn't be happier with the results. Right from the start, TFS offered very competitive prices and provided excellent guidance in sizing an appropriate system for my house. The installation process was flawless. The team was on time, performed a neat and professional job, and took the time to do a great job explaining the system to me. The positive outcomes are already clear: I am seeing substantial savings on my electric bill, which is exactly what I hoped for. Their great follow-up service further confirms their commitment to their customers. I am extremely happy with the service TFS provided, and I know others who have used them and are”
