Aztec Solar isn't worth the risk. We found a company where positive workmanship mentions barely outnumber negative ones, and value scores sit at an alarming 3.0 out of 5. One customer didn't discover their tile-roof project was canceled until a refund notification appeared on their credit card statement, 10 days before install. Another tried for a month to get a callback about a malfunctioning panel under warranty and never heard back. The pattern is clear across 39 reviews: responsive sales reps vanish after the contract is signed. Post-sale support scores just 3.3, with 60 negative mentions of delayed service, ignored warranty claims, and installation errors left unresolved. Yes, 123 reviewers praised the installation crews for being punctual and professional, and pool-heating customers report warm water by mid-March. But competent installers can't compensate for an office that ghosts you when a panel fails or bills you for work on a system you removed three years ago.
If you want a solar company that answers the phone after install day, keep looking. Aztec's install teams are solid, but we found too many customers left stranded when equipment failed or billing went haywire.
Jennifer and Elisabeth W. began shopping for solar in May and signed a contract with Aztec the first week of June, paying a deposit and expecting a quick scheduling call. Weeks of promised follow-ups went nowhere until they phoned the office and were told roof inspectors would come July 12 and the install was set for August 8 — but two inspectors actually showed up on June 12, climbed a ladder, glanced at the tiles and left after about ten minutes. Because they work from home and have two dogs, they called back to ask about noise and were advised to take time off and board the dogs — so they rearranged days off and paid for kennel care. Ten days before the slated install, they discovered a refunded deposit notification from their credit card and only then learned the project had been canceled because Aztec claimed the tile roof made the job impossible. A company representative named Mark Lillie never reached out, and when the owners finally called back the couple, the owner offered only that Aztec would proceed if they hired a roofer first — with no apology. Frustrated by the lack of communication and the fact the cancellation showed up as a refund rather than a direct call, they决定
William R. purchased a residential solar system in November 2021. After an early panel fault that the company fixed, the same panel began malfunctioning again in January 2023. He contacted Aztec Solar customer service and initially heard nothing back despite several calls; when a technician finally phoned, he offered a preliminary diagnosis and said someone would come out on Monday, February 6, 2023. William waited and kept calling, but by February 27 there had been no technician visit and no explanation for the delay. The experience settled into a clear takeaway for him: the company resolved the first fault, but the follow-up and communication after the January recurrence — a promised Feb 6 appointment that never materialized and nearly three weeks of silence — is the detail future buyers should weigh.
Maryann enjoyed her Aztec solar panels for the pool for years after they went up in the early 2000s. After her beloved husband died in 2022 she replaced a leaky roof with Spartan Roofs, and the panels were no longer on the roof from that point forward. This year she began receiving invoices from Aztec claiming a job on 6/5/25 for $729.26. She called Aztec on 6/30/25 at 11:12 a.m. to explain there were no panels on the roof and to ask that her late husband be removed from their system; accounting assured her they would remove him. Despite that promise, six more invoices arrived, each including threats of collections and a lien, so she called again on 8/4/25 at 12:13 p.m. and spoke with Victoria in accounting, who apologized and said she would remove the record. Then an invoice dated 9/16/25 showed Aztec planning to send the account to collections on 9/24/25. What stands out is that she attached photos showing the panels gone and the tubing where it used to feed the pool equipment, yet the company continued billing and escalating collection threats — a pattern that has caused her significant stress and remains unresolved.

Bruce already had Aztec equipment heating his pool and discovered his roof’s best array location could still work — Aztec simply moved the pool panels and built around them. They recommended a 32-panel system for his home (bigger than his immediate need but sensible given tree shade and a future electric car), installed a 240‑volt outlet for that car, and handled all contact with PG&E and county inspectors. Clint Cary guided him through the steps, and the install finished in November 2022. Through several winter storms the array stayed put, produced power even on very cloudy days, and left him watching the meter spin backward so he now pays about $10 a month to PG&E. He compared other bids and found one competitor wanted to install fewer than 20 panels and lock him into a 20‑year lease; buying outright through that company would have run about $10,000 more than Aztec’s price. Having relied on Aztec for pool equipment service for years, he trusts that if anything goes wrong he only needs to call them and they’ll send someone out. The detail that sticks with him: a full install that included relocating existing pool panels and adding EV wiring, completed before winter, that quickly t
Pam M. first had Aztec install solar panels on her home about three years ago. When PG&E raised rates she went back to expand the array in 2022 and also had them replace and install a new solar pool heater. Aztec remained professional and easy to reach by phone or email, scheduled both projects within a reasonable timeframe, and walked her through the technical details in plain language. She ended up with a larger rooftop system and a working solar pool heater, and what stuck with her most was their accessibility and clear explanations that made the upgrades feel straightforward.
Patrick B. had Aztec replace a leaking roof-mounted solar system in 2021, after initial work left plumbing leaks at the roof’s edge that required a return visit. This season he turned the system back on and tripped an open solar sensor warning on the controller. He called Aztec and was quoted a fee structure: $130 for the first 15 minutes, $30 for each additional 15-minute block, a $10 travel charge to Rocklin, and $130 more if they needed to replace the sensor — a part that sells for about $20 on Amazon. Because his wife didn’t want him on the roof he booked a service call, but after reconsidering he climbed up himself and discovered the problem: the roof sensor was strapped down with a zip tie and left with roughly three inches of slack. Years of wind had let the wire flop until it broke. When he explained the shoddy installation to the company they still intended to charge for the visit, so he canceled the appointment and reunited the wires with a couple of wire nuts. The detail that lingers: an inexpensive sensor and a careless zip-tie job — not a complex fault — caused the outage, and the quoted service and replacement pricing pushed him to handle a simple fix himself.
Sheri R. hired Aztec to put solar on the Estes' Stockton home, and after a year she walked away impressed by how smoothly everything went. She experienced a crew that was 100% responsive and handled every step — permits, scheduling, installation and coordination — without a single glitch. The payoff became unmistakable at the twelve-month mark: their PG&E year-end statement arrived as a $140 credit, with no true-up bill to pay. The lasting detail that sticks is simple and concrete — flawless project coordination that delivered a real $140 credit on their annual utility bill.
Ten years ago Jaime De Avila hired Aztec Solar to install eight solar panels on the roof specifically to heat the backyard swimming pool. They remember the crew as professional and reliable and regard the small, purpose-built installation as a job well done even a decade later.

e.e. bunny has worked with Aztec Solar for more than 30 years, building a decades-long relationship. Over that time they found the company repeatedly exceeded expectations—quality and service that kept them coming back. The single snag has been popularity: Aztec has gotten so busy that appointments and scheduling can take longer than desired. The clear takeaway: dependable, long-term workmanship, but plan ahead—excellent service here often means a wait.
Sara J. has relied on Aztec for several years to service the solar setup that heats her backyard pool. She values how easy it is to reach the company and schedule appointments; when technicians arrive they’re polite, work quickly, and handle the job without drama. Consistent responsiveness and tidy, fast visits are the detail that keeps her calling Aztec for ongoing pool-solar maintenance.
Danielle Hatcher invested in a solar pool‑heating system for her home and, after two full seasons plus the initial partial season, ended up deeply frustrated with the post‑installation support. What stands out most: Aztec charged her $180 for a short onsite inspection to check for leaks even though the system was still under warranty — she paid $180 for about fifteen minutes after several gutter repair contractors warned water was running into the gutters. She discovered multiple installation issues: valves were placed incorrectly, the timer was set improperly, and air kept getting into the tubing so bubbles appeared at the pool return. Her pool technician despised the device Aztec installed — it turned out to be a solar switch with a baffling, illogical timer function rather than a proper timer. When she questioned the fee while the system was under warranty, the company's answer boiled down to needing to “stay in business,” which left her feeling dismissed. Aztec did send someone who couldn’t find a leak but still billed the visit, and follow‑up communication faltered — a promised callback was missed and later voicemails went unanswered. Over the next week the problem wors
