SunFusion Energy Systems reviews

Susanne met Walter Ellard, owner of Sunfusion Solar, at the Del Mar Fair this past June after having thought about solar for roughly 40 years. She had longed for a battery-driven system but imagined rows of hazardous batteries filling a garage — until she discovered Sunfusion’s hybrid setup, which stores power in a refrigerator-sized unit. The system ties into SDG&E with an automatic transfer switch that flips to the grid if needed, so the house stays powered seamlessly. Sunfusion installed the system on her Encinitas duplex, ended up powering both units, and added air conditioning that has been working fantastically. Walter’s deep knowledge of hybrid technology showed through; he, his wife Sandy, and their crew worked professionally, left the site tidy, explained each step, and welcomed questions and onlookers. The detail that stuck with her: a compact battery bank and automatic grid switching finally made a decades-long dream practical and gave the duplex reliable power plus cooling.

Rachel ended up with a solar install that never matched the contract she signed, and that mismatch quickly turned into a headache with the state rebate process on what should have been a straightforward home energy upgrade. The equipment on the roof and the paperwork in the rebate file did not line up, and for a while it looked like the household might miss its reimbursement entirely while trying to explain the change nobody had been told about. That stress only deepened after the system went live. For more than two years, she kept running into unresolved problems, including flickering lights in the house, an unreliable monitoring app that never gave a clear picture of production, and an inverter setup that even Sol-Ark technical support thought needed a closer look from the installer. What stood out most was the silence afterward: she spent more than two months trying to get someone from SunFusion to review the system and never got a response, leaving her stuck with a major solar investment and no real post-installation support.

Mark B. hired Sunfusion to install solar panels on his roof in August 2023. The installation itself went smoothly and the panels are working fine, but after the first rain this year he discovered a leak — only because he was fixing a nearby curtain and noticed water damage. During the sale he had been verbally assured that any problems would be handled, yet getting the company to respond after the leak became a major headache. He emailed Sunfusion a roofer’s estimate and photos, called several times and hit voicemail, and tried texting and calling the owner; the owner texted that he would call back but never did. The roofers he brought in said they normally lift tiles and lay new underlayment before panels go on — a step Sunfusion apparently skipped — which the roofers pointed to as a likely reason for the leak. He walked away with functioning panels and no other complaints, but left a one-star review because the installer never engaged on repairs; he wouldn’t have written this if Sunfusion had simply responded, even to refuse covering costs. Takeaway for buyers: get written confirmation that tiles will be lifted and new underlayment installed and insist on a clear post-install 연락처

Jacquie H. chose SunFusion for her home's solar system and discovered a team that treats relationships as part of the product. She found Walter and the crew genuinely invested in making the system perform — not just installing panels but explaining how it works, recommending improvements, and following through on fixes. The group stayed unusually responsive; when questions or tweaks came up they answered quickly and provided practical help. What stuck with her most was the ongoing care after the sale: Walter’s personal attention and the team’s willingness to improve the system rather than move on to the next job.

Michael F. had a SunFusion solar-and-battery setup on his home for a couple of years, but three weeks ago the system began causing flickering lights at night. He rebooted the unit, checked the Wi‑Fi and unplugged sensitive devices, then tried to reach SunFusion for service only to find the phone unanswered and an automated line that doesn’t identify the company. After leaving messages, Walter from the company replied by email to say he would file a service request and someone would call to arrange an appointment — the call never came. Michael stopped by the listed office and found it locked, and more email exchanges with Walter produced no fix or meaningful help. His unease dates back to earlier visits: Walter once installed a small Wi‑Fi booster so the SunFusion unit could get a signal, then later sent technicians back to rewire the battery connection. When Michael inspected the work he discovered more consequential changes — the original converter for the solar panels had been bypassed, and part of the busbar in his main electrical box had been removed unnecessarily. He believes those alterations would never pass inspection and points out that a busbar defect figured in a fire

Jay K. bought a rooftop solar system three years ago and ended up with panels scattered across the roof in a layout that made the roofline look awkward and unplanned. Technicians did return during the first 18 months to fix a handful of offline issues, but that early responsiveness faded: the system has been offline for six weeks and he has been unable to reach Walter by phone or text. Frustrated, he’s now looking for a new solar repair company to restore power and straighten out the messy installation left behind.

Herman bought an Echo5t battery system for his all-electric home and quickly discovered his electric bills dropping — he’s now using borrowed electricity off-peak and seeing noticeable savings. Walter came across as honest and polite, stayed true to his promises, and remained available when needed; he’s often busy, but texting made it easy to get a reply. The system kept the house powered through recent outages, including one that hit on Thanksgiving during dinner, and Walter even texted to check that everything was working as promised — it was. Walter also pointed him to the state SGIP program, and he’s now waiting for that reimbursement check in the mail. What stood out was the personal touch: a technician who not only installed the system but reached out during a holiday outage to confirm it performed.

Kristen J. had rooftop solar panels installed about four years ago and began noticing wet spots in her bedroom ceiling directly beneath the main array. She picked SuperGreen Solutions (now out of business) for the project, but SuperGreen had subcontracted installation work to SunFusion — the company she’s been trying to get to honor a warranty ever since the leaks showed up. After repeated unanswered calls, she escalated to the BBB to force a response. SunFusion replied: Sandy sent a poorly written email, and then Walter visited the house. He inspected the roof and painted a dramatic picture that her entire roof was ruined — blamed the problem on something other than the installation — and even pivoted to offering tax advice if she hired him to replace the roof. Two independent roofers later confirmed what Kristen had hoped: the roof itself wasn’t fundamentally damaged. In SunFusion’s BBB response Walter went so far as to fault her for not noticing the leak earlier, despite the system having been up for four years — an explanation she found both unfair and unprofessional. An inspector who came out couldn’t remove the panels to investigate further, and having that work done is “

Ralph ended up spending $35,000 on a 15 kW whole-house battery backup from Sunfusion in 2023, only to have the setup fall apart within two years. The battery compartment kept tripping the breaker, there was a persistent odd smell around the system, and any time trouble came up he ran into the same wall: no returned calls from Walter Ellard, the CEO who seemed to be the only person handling everything. After giving up on the Sol-Ark inverter and sending the batteries to the landfill, he replaced the whole setup with a Tesla system and felt much better about it.
