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.

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.

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.

In early summer 2015, just after buying a fairly large property with a guest house, workshop and two big wells, San Pietro Progettista opened his first SDG&E bill and discovered a $1,400 total. That night at the Del Mar Fair he met Walter and the Sun Fusion crew, explained the high usage, and arranged a site visit the next day. Sun Fusion surveyed the home’s electrical setup and, two days later, presented a range of solutions. He ended up with a substantial install: a 16 kW rooftop array with microinverters to offset the house load and a separate 4 kW ground-mounted array dedicated to the variable-speed pool pump — a package that required 53 LG panels on the roof. Sun Fusion steered him through financing and helped secure a HERO loan, all within a week. Equipment lead times and permit delays stretched the calendar until October, but when permits cleared the main array went up in two days. The installation crew worked quickly, had a good attitude and cleaned up after themselves; the ground-mounted pool array took longer because of rain and extra trips to test, fix leaks and calibrate. One standout moment: he watched a 4 hp pool pump run at full throttle powered entirely by sunlight.

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 “

Janet J. spent about $50,000 on a solar system that was supposed to make her home fully off-grid. Instead she discovered the installation had damaged both the solar array and her electrical service, and the work removed 200 amps of power to the house. The installer, Walt Ellard, never showed up to address the problems or return calls, so she ended up paying roughly $1,500 to have the system taken down. The clearest takeaway: the system was installed incorrectly, cost far more than expected, reduced her home’s electrical capacity, and left her to shoulder removal costs with no reliable point of contact.
