Treeium Energy reviews

The Verdict
Treeium Energy isn't a solar company. We analyzed hundreds of reviews and discovered they're primarily a general contractor doing home remodels, bathroom conversions, and room additions, with solar as a sideline. One homeowner thought they were hiring a solar installer and got a bathroom quote instead. The disconnect runs deeper than marketing. While 142 reviews praised sales reps for being friendly and responsive, 38 flagged poor value and 32 called out workmanship problems. The company leans heavily on two quality-assurance staffers, Gina and Greg, who show up in dozens of reviews fixing post-project issues like misaligned mirrors, foggy windows, and leaky roofs. That's a red flag. A well-run solar installer shouldn't need a dedicated repair team chasing down shoddy work months after closeout. If you want solar panels, hire a company that installs solar panels every day, not one that treats it as an upsell to kitchen remodels.
If you're looking for a solar installer, skip Treeium. They're a remodeling contractor dabbling in solar, and their track record shows it. Find a dedicated solar company with consistent installation quality instead.
Reviews That Shaped Our Verdict
Shawn hired Treeium to replace his entire roof, and two years later a leak appeared. Even though his labor warranty had expired, Treeium’s Quality Assistance team came back, patched the roof at no charge, and stayed engaged until the problem was fixed. Gina handled communications with kindness and kept him updated through every step, while Greg coordinated the repairs and made sure the crews followed through. What stuck with him most was that the company returned after two years and corrected an out-of-warranty leak for free, maintaining steady contact until the roof stopped leaking.
Ben Sanada bought a 2,700 sq ft ranch-style house in Laguna Niguel and decided to gut and renovate almost the entire place a few years ago. After talking with three companies, he chose Treeium Inc because the firm looked well established and Shay Cohen listened patiently to his plans to make the home more modern and spacious — including tearing down some walls. Three years on he discovered a few minor issues, but they caused little headache because Gina Cada in Treeium’s Quality Assurance department stepped in to help. One of the 48 replacement windows has started to go foggy; COVID-19 has slowed the replacement timeline, but Gina has kept him informed of the service process at every step. He was pleased when the renovation finished and remains satisfied with the follow-up care; what stuck with him most was the steady aftercare — a single faulty window among dozens being actively managed and communicated about during a difficult time.
Aaron M. manages a duplex and commissioned what turned into two separate solar installs: one system for his unit and a second for the upstairs neighbors. Because the available rooftop space was fully used for his system, the neighbors’ array had to go on the detached garage roof, which required trenching a long run of conduit between buildings and pulling multiple permits — for the trench, for two distinct systems, and for the roof work. Installing panels also prompted a full roof replacement with 3-inch rigid insulation boards to reduce summer heat, adding another layer of permitting and coordination. Treeium arrived with a fair price when Aaron was only initially quoting one system; when the project grew to include the second system, trenching, and the complete roof upgrade, they adjusted the scope and carried the project through. Ashley Arndt, the production manager, handled day-to-day communications — answering emails, messages and calls promptly — and kept the job moving on schedule. In the end he walked away with two working systems and an upgraded, better-insulated roof, and a clear impression that Treeium can handle a more complicated duplex install without letting the ball

What You Can Expect
In 2020 Joseph B. handed Treeium a $1,000 deposit for a set of solar batteries. He never received the batteries and the deposit was never returned; he later heard the company had gone bankrupt, leaving him out the money and without the equipment he ordered. The lingering detail that will stick with buyers is how a relatively small upfront payment vanished when the company collapsed, with no clear path to recovery.
Dee invested just over $20,000 in a solar system that’s still under three years old and ended up with a leaky roof and panels that aren’t producing as promised. She signed on after a salesperson made big promises, but the project quickly hit a wall: the backup battery was installed incorrectly, and it took almost eight months to get a working replacement because the company kept turning over staff. The representative handling her account left, no one immediately took over, and she spent months trying to get anyone up to speed on the problem. A year after that mess, her Southern California Edison bill climbed back to pre-solar levels. Treeium Inc. told her the service warranty had already expired (it was only a one‑year service), and now they expect her to pay for someone to diagnose why the system isn’t producing—while the company’s monitoring shows the system as online. She found herself stuck between Treeium and SoCal Edison with no clear resolution, covering extra costs on a system that cost tens of thousands. Dee has warned neighbors not to attempt to use Treeium Inc.; the detail that keeps sticking with her is how long it took to get competent follow‑up once the original rep
Paxton Swafford bought two solar batteries from Treeium in October 2020 as part of a home energy job. After years of little progress, he asked for a refund on February 23, 2023. An employee offered reassurances, and a technician who arrived in early March discovered the originally planned battery placement wouldn’t pass code and that two batteries had been oversold for the loads they expected to serve. Paxton changed the order to a single battery for emergency backup and agreed to move its location. On March 24, 2024 Treeium said his battery was ready — but by the time the permit cleared, the company had given that battery to another customer. Paxton provided his bank routing information for a refund, but the payment never posted. Repeated requests were ignored; staff then tied the refund to project completion, which he found unacceptable without a completion date. After executives conferred, Treeium promised to return the funds in four monthly installments. Following legal advice, Paxton sent a Demand of Payment on May 24, 2023 and met the CEO on June 23, 2023, where he verbally accepted the installment plan as a favor to the CEO given Treeium’s financial troubles.
