Aztec Solar reviews

The Verdict
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.
Reviews That Shaped Our Verdict
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.
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

What You Can Expect
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.
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
Denise had relied on Aztec Solar for years, paying about $189 for winterization and spring tune-ups on her pool solar system. This spring, after the pool crew turned the panels back on they discovered a cap was missing and water was running down the roof. She called Aztec to schedule the spring service and flag the missing cap; the technician on the phone treated the issue as a repair (even though no one else had touched the system), quoted $134 for the first 15 minutes and $22 for each additional 15 minutes, and pointed out a $229 combo for spring and winter service. When Denise pushed back that the cap wasn’t broken but simply missing, the rep offered an alternative: try Sierra Pacific Solar if she didn’t want to proceed. The conversation left her surprised and frustrated — the labor pricing and the suggestion to call a competitor were the reasons she decided to seek another company.
