Sunko Solar reviews

Jim chose Marco to design and install solar on his Los Angeles home — a house that runs central air and regularly charges electric cars. He encountered several unique site challenges during planning, and Marco worked through each one, walking him through clever, practical solutions and staying personally engaged from quote to commissioning. Marco’s crew showed up on schedule, worked quickly and courteously, and accommodated the family’s timing. Once live, the system started banking credits with LADWP within months and has more than kept up during LA summer peaks, even with ACs running and EVs charging. After spending time with a more popular competitor that felt impersonal and unfocused, he ended that exploration and went with Marco — the difference in hands-on attention made the choice obvious. The detail that stuck most: the system delivered real LADWP credits through the hottest months, so the payoff felt immediate enough that he wishes he’d done it sooner.

Katie Penna searched for years for a solar company she could trust and ultimately chose SUNKO Solar to outfit her home. She discovered owner Marco Iwabuchi and his team went well beyond expectations: Marco’s friendly, reassuring personality made her comfortable with the decision, and the crew backed that up with clear communication, competitive pricing, and solid workmanship. They managed the installation with attention to detail and kept her informed through the process, leaving her confident enough to recommend SUNKO to friends and family. The detail that stuck with her was Marco’s personable leadership paired with the team’s consistent follow-through.

Tyler Rebbe bought a house last year with the solar panels already paid for and assumed the system was functioning. In January a shockingly high electric bill revealed the inverter had failed and the array hadn’t produced power for months. He called Marco at Sunko Solar; Marco and a technician came out at least three times to diagnose the issue, then persisted with customer service and the manufacturer until a replacement inverter was approved. Marco handled the logistics and the warranty fight, completed the repairs at no charge, and stayed on the case until everything was back online. A month after the swap the system runs properly and Tyler’s next bill was minuscule — the clearest takeaway being that Marco not only fixed the hardware but navigated the warranty hurdles so the homeowner paid nothing for the repair.

Tyler moved into a home last year that already had a paid-off solar array and assumed it was working — until a shockingly large January power bill revealed the system hadn’t been producing power for months because the inverter had failed. He called Marco at Sunko Solar, who showed up with a teammate and returned at least three times to run diagnostics, trace the fault and keep pushing on the phone with customer service. Marco refused to let the problem rest, eventually forcing the manufacturer to replace the defective inverter. About a month after the work started, the system was back online and Tyler’s next bill was miniscule. The repairs and replacement were handled at no charge. The detail that sticks is Marco’s persistence — multiple on-site visits and tenacious negotiations that turned a months-long outage into a working system with no cost to the homeowner.

Monica M. hired Sunko Solar to install rooftop panels on her home and found Marco extremely responsive and professional from start to finish. He walked her through the whole process and handled scheduling plus all arrangements for the installation and inspection, taking the logistical burden off her shoulders. She appreciated his personable communication and hands-on coordination, which made a potentially complex project feel straightforward. For someone who wants a single, attentive point of contact to manage logistics and inspections, that level of follow-through was the clear standout.

Steve hired Sunko Solar and owner Marco Iwabuchi to install rooftop panels on his home, which had a large, north-facing roof that slopes downward — a setup that would normally reduce output if panels simply followed the roof. He watched Marco and the crew move quickly and professionally: they stuck to the contract and budget, finished the install, and had LADWP approve and turn the system on in about two weeks from the start of work. Where other companies balked, Marco tackled the problem with a "reverse tilt" solution, raising the back (down-slope) edge of the panels about 18 inches so they could better face the southern sun and capture more energy. Steve included photos that show the tilt detail and a side view of the house, and from July 20 through August 14 the system produced a daily average of 55 kWh. For anyone with a north-facing, down-slope roof, the concrete takeaway that stuck with him was Marco’s practical reverse-tilt approach — it turned a challenging roof into a productive array.

Michael hired Sunko, led by owner Marco, to put solar on his house. He discovered from the first conversation that Marco would walk him through every step — from financing options to the physical install to how the system would tie into the utility — and that Marco stayed reachable day or night for questions. Marco also took responsibility for dealing with the electric company, following through on interconnection steps so the handoff felt seamless. The crew finished the install in a day and a half, exactly on the timeline Marco had projected, and communication remained easy throughout. What stuck with him most was the combination of Marco’s around-the-clock availability and his hands-on utility coordination, which turned a potentially frustrating paperwork process into a smooth, tightly scheduled project.

Michael R. chose Sunko to install residential solar and discovered the owner, Marco, handled the project with clear explanations and steady communication. Marco fielded questions at any hour, day or night, and delivered the physical install in a day and a half exactly as projected. He also took care of the back-and-forth with the electric company, smoothing the utility and interconnection steps so the whole process felt seamless. Michael appreciated that Marco wasn’t just personable and easy to talk to—he knew the business from financing through installation to utility integration—and that expertise turned what can be a complicated project into a quick, on-schedule job.

Mark P. shopped several companies when planning a residential solar install and discovered Marco at Sunko Solar stood out for being refreshingly professional and knowledgeable. Where other firms gave negative or hesitant answers about adding panels to his house, Marco offered clear, positive solutions that made the decision easier. He watched the Sunko installation crew work quickly and skillfully, completing the job without fuss. He recommends contacting Marco for installation and service — and if he had another house, he would have Sunko Solar handle that one too.
