Solar Alliance reviews

The Verdict
Solar Alliance isn't worth the risk. We analyzed dozens of reviews and found a troubling pattern: 23 customers described systems that underperformed, warranties ignored, and communication that disappeared after installation. One homeowner spent six months chasing a quote for additional panels because their warranty would void if anyone else touched the system, then endured four redesign attempts and a failed inspection because the company installed the wrong plaque despite being told it was incorrect. Another paid $300 out-of-pocket when their system died after 18 months, then discovered three years later that the roof work Solar Alliance contracted during installation had been leaking into their attic the entire time. The company took three weeks and multiple no-shows to send someone. We found 30 complaints about project management failures, 25 about sales conduct issues, and 24 about post-sale support breakdowns. Six recent reviews report phones ringing unanswered and emails ignored for weeks. The positive reviews cluster in earlier years, while 2024-2025 reviewers describe a company that has stopped responding entirely.
If you're researching Solar Alliance, know that recent customers can't reach anyone for service calls or new projects. The pattern of ignored warranties, botched installations, and vanishing support makes this a gamble you shouldn't take.
Reviews That Shaped Our Verdict
Carson had hired the company before and the previous rooftop project wrapped up on good terms, so he reached out again expecting the same level of service. He gathered three separate ways to contact them — the office line, a mobile number, and an email address — and tried each. For four weeks he received no callbacks, no returned emails, and no response from any of the three contacts. Frustrated, he advised others to take their business elsewhere. The company owner pushed back on the review, saying they had tried the main number and suggesting Carson could pull his number from their system so the owner could call him directly, implying the communication problem wasn’t entirely on their end. What sticks is the contrast: a smoothly finished prior job followed by a month of silence despite multiple contact attempts.
L B. had rooftop solar installed three years ago and is still dealing with fallout from what began as a service call: a roof that was supposed to be repaired before the panels went on now leaks into the attic, and after an onsite admission from a Solar Alliance representative that the roof work wasn’t done correctly, they have waited more than three weeks for a proper fix. They paid Solar Alliance to arrange the roof update when the system was installed, then discovered the contractor’s work failed. About 18 months after installation the solar system stopped working, and because the company would not cover the outage beyond a two-month window, they paid $300 out of pocket to get electricity restored while their bills climbed. Since the roof problem surfaced, multiple phone calls have produced missed appointments — a crew was scheduled two days ago and didn’t show, and another scheduled for today also failed to arrive — and attempts to reach the owner went nowhere. The most lasting detail: the company’s contractor admitted the roof wasn’t fixed correctly, yet the leak remains and scheduled repairs keep being missed, leaving ongoing damage and mounting frustration.
Anne C. had been satisfied with a 12-panel system installed two years earlier, then decided to add ten more panels after a new pool began draining more power. She waited six months just to get a quote and felt she had to stay with the original installer to avoid voiding the existing warranty. She signed the contract on 09-27-13, but the project stalled: after many calls the crew finally began work only two months later, and early mistakes revealed they hadn’t done a proper site survey. The company initially submitted the old design to the county without accounting for vents and risers on the roof, so a designer had to come back and redraw the array. Net-metering approval dragged on through four separate submissions because the one-line diagram didn’t match the application. The physical install stretched over four days and finished on November 29; the county inspector didn’t arrive until December 5. A technician from Solar West brought an updated plaque, but it was incorrect; when Anne pointed that out he called his office and was told to install it anyway and “we’ll fix it later.” As a result the inspection failed — the county didn’t have the revised plans and the plaque showed the

What You Can Expect
Timothy Klein had a 5.2 kW solar system with a battery installed on his city home in Knoxville and found the installation itself clean and efficient. He received email replies within 24 to 48 hours throughout the process, and the crew worked quickly, left the site neat, and delivered solid workmanship. A year after the install his array continued to perform as expected, and when a component recall and a failed controller cropped up, Solar Alliance didn’t wait for him to chase them — they initiated the fixes promptly. What lingered most for him was the company’s follow-through: timely communication during the project and proactive, effective service afterward.
Robert Kahn owns a nine-year-old PV system with 36 panels and microinverters. When one microinverter began underperforming, he contacted Solar Alliance Southeast and worked with Kevin to pinpoint the fault. Because Robert lives about 100 miles from their office, Kevin avoided an expensive round trip by ordering a warranty replacement and having it shipped directly to him with clear instructions for swapping the unit. He installed the part himself at no charge and now plans to call them again when he wants to upgrade or expand — the thing that stood out was Kevin arranging the shipped warranty part plus step-by-step guidance, saving a long drive and extra labor fees.
Nanette bought a rooftop solar system from Solar Alliance about four years ago and financed it through a third‑party loan. She took the deal partly because the salesperson framed the loan around an $8,000 tax credit that would offset the cost. After installation she discovered the credit didn’t materialize as promised: her tax situation allowed only about half the credit the first year and just a small portion the second year. When she contacted the company to explain the shortfall, the response felt like a shrug — no real remediation or help followed. A few months later she changed her home internet and the solar gateway lost its connection, so she couldn’t pull production data or monitor output. She learned that only one tech at the company handled that kind of fix and he was on vacation; it took three weeks to get any contact. They promised an explanatory email on how to reconnect, but it never arrived, leaving her to chase them for support. When her household added a pool and she asked to tack a single panel onto the array to cover the extra load, Solar Alliance told her the smallest option was buying six panels at roughly $1,000 each. That rigid upsell — rather than offering
