Tenco Solar reviews

The Verdict
Tenco Solar is a safe repair and service option, but less proven on new installs. We analyzed over a hundred reviews and found 53 homeowners praising workmanship quality, with zero complaints about techs cutting corners or skipping steps on repairs. One customer hired them after a previous installer vanished mid-job, and Tenco diagnosed a faulty junction box and fixed it same-day. Another had an inverter spitting error codes for weeks; Tenco replaced it and walked them through the readouts until everything tracked. The standout pattern is responsiveness. When a homeowner's bank account was drained by a $12,000 billing error, the owner texted excuses instead of wiring the money back immediately, and the crew left razor blades in the yard where a toddler played. That's the trade-off: strong technical skills, uneven follow-through. If you need a broken system brought back online and your original installer is gone, they'll likely solve it. But if you want white-glove communication or a company that owns mistakes instantly, keep shopping.
If you're comparing new-install quotes, you may find smoother project management elsewhere. But if your panels stopped working and the installer who put them up is out of business, Tenco's diagnostic speed and repair expertise make them worth calling first.
3 Stories That Stood Out
After a previous installer left an incomplete, poorly executed solar setup, Jeff called Tenco. He got a rapid response and a technician on site quickly; the tech diagnosed the fault and repaired the problem in short order. The experience centered on fast troubleshooting and an efficient fix rather than drawn-out follow-up. Jeff walked away reassured that Tenco will step in to correct another contractor’s mistakes and handle solar maintenance reliably.
Rachel discovered her bank account had been debited for $12,000 more than she had authorized after a solar installation on her home — $12,000 beyond the total bill. The withdrawal hit on Sunday and she only noticed it Tuesday; she panicked, called the company Tuesday morning and asked them to wire the excess back immediately. She then sent a paid invoice proving the correct amount had been entered, and an employee had even called earlier to confirm her payment details. Dan McIntyre, who identifies himself as the owner, texted that she had “probably entered the wrong amount” and that they were sending the money back, adding that it would be “At our own expense.” He later told her he’d attempted the wire twice: once rejected by his bank as flagged fraud, and then resent. By Tuesday evening she still had not received the funds, and she questioned whether the company would cover any wire fees or bank late fees their error had created for her. What pushed her from quiet frustration into writing a public review was another safety issue: her husband found multiple razor blades and cut electrical wire left in the yard after the install — a hazard to their dog and toddler that they only
Kevin O. discovered his roof-mounted inverter was spitting error codes and, with the original installer out of business, tracked down Tenco to repair or replace the unit. Hector climbed onto the roof, cleaned a junction box that had flooded from poor seals, and logged the inverter errors, then called in a colleague to take a closer look. Luis concluded the inverter needed replacement and had a new unit ordered right away. When Luis returned to install it he couldn’t finish because a neutral wire was missing and he had to leave for another job, promising to come back the next afternoon — but he never showed or called. When Kevin phoned the office, Clarissa didn’t know the job was still undone and couldn’t schedule anyone until after the weekend. Two technicians, Orbisk and Randy, arrived the following Monday while Kevin was away; afterwards he could see the electric meter running backward, but the new inverter showed no digital readouts or any sign the system was active. Orbisk and Randy came back the next day, phoned the manufacturer, and discovered a cable that feeds the inverter’s digital display and production readouts had not been connected.

What You Can Expect
Kim T. has known Matt for years and trusts him in a way she reserves for very few contractors. She has relied on him repeatedly because he’s always reachable, will come out and fix whatever’s needed, and won’t push upgrades or services she doesn’t actually need. For a homeowner who usually keeps her guard up around contractors, Matt’s long-term view on customer service — thinking beyond the immediate sale and focusing on being someone she can count on — made the difference. The work lasted, the follow-up was prompt, and what stuck with her most was that she can pick up the phone and get a dependable answer rather than a hard sell.
Andrew Allen Erman chose Tenco for a residential solar installation because he felt he could trust them, and that trust paid off. He found their bid competitive and the sales process with Robert Rios smooth—Robert answered his many questions right away and laid out clear information. The contract was easy to follow, the crew finished on schedule, and the installers were professional, friendly, and helpful. A snag with his existing electrical panel forced a more involved back-and-forth with the utility and Building and Safety (an issue he took responsibility for), but Claryssa stepped in at every turn—guiding him, contacting agencies on his behalf, and keeping him calm. The system is now operating as expected and he’s pleased with the outcome. The detail that stands out most is how Tenco’s staff handled the permitting and utility hassle personally, turning a potentially stressful complication into a finished project.
Barbara hit a snag when her inverter quit communicating and the monitoring app wouldn’t connect to her phone. Hector arrived, quickly diagnosed the inverter issue and got the mobile app working on her cell, handling the fix with evident professionalism. She left with a functioning inverter and the app linked on her phone — a tidy, prompt resolution that stood out for its speed and customer care.
Arthur had Matt install solar panels for his pool eight years ago, and when he arranged a recent check-up Matt returned and delivered the same reliable service. He found Matt professional and knowledgeable, arriving on time and behaving courteously throughout the visit. What stood out was the long-term follow-through—after eight years the installer still came back for routine care and offered clear guidance—so he recommends the company for solar work and expert advice.
Mary had solar panels on her roof that weren't producing, and Tenco Solar stepped in. The crew moved efficiently and professionally, discovered the system hadn't been commissioned, and patiently walked her through what that meant. They corrected the problem while remaining cordial and polite, and she ended up with panels that are now working — a simple, clear fix after some confusing technical trouble.

Laurie ran into an unexpected failure with the pool solar heating at her home and called the company for help. She found the team fair and straightforward, flexible with arrangements, and unusually easy to reach. When the issue became urgent they jumped on it and resolved the problem right away, restoring her pool heating with minimal fuss. The detail that sticks with her is their rapid, dependable response in an emergency—clear access to help when it mattered most.
Dean Berkus MD hired Tenco Solar to install rooftop pool panels (Fafco) and ended up pleased with the job. He found the technician arrived on time, was courteous, completed the installation and left the site when the work was finished. He paid a premium — Tenco is expensive — but the workmanship matched the price; in a time when finding skilled installers is tough, having a competent tech on the roof made the difference. Given that outcome, he would hire them again for another rooftop Fafco pool panel job.
Patty C connected with Tenco Solar and found the whole process refreshingly straightforward. She dealt with Claryssa in the office and Ulises in the field, and both stood out for clear, plain-English explanations that helped her understand every step. The crew handled the work on schedule, answered her questions, and left her confident in the installation. She ended up deciding Tenco Solar will be her go-to for any future solar needs — a choice driven most of all by the personable office support and punctual on-site service from people she now remembers by name.
