The Verdict
We recommend Luminalt without reservation. They installed SunPower panels on a three-story Victorian with a battery location problem that another installer gave up on after months of silence, then worked through fire code exceptions and got pre-approvals before installation so inspections sailed through. We analyzed reviews spanning over a decade and found 74 mentions of workmanship quality with only 3 complaints, and not a single negative word about their follow-up support even on systems they installed years ago. Two patterns stand out. First, their project managers don't vanish after the sale. When one homeowner's power went out on a Saturday, the service lead called back in five minutes and had an engineer at the house within 45 minutes to troubleshoot a downed PG&E line that had nothing to do with the solar install. Second, their crews finish early and clean obsessively. A four-to-five-day job with panels, a Tesla battery, and a car charger wrapped in three days, and the homeowner noted the installers swept and vacuumed daily instead of leaving lunch trash around.
If you want the cheapest quote, keep shopping. But if you want an installer who'll show up on a weekend to replace a fuse at no charge ten years after your install, or who'll navigate tricky fire code approvals instead of walking away, Luminalt is worth the premium.
3 Stories That Stood Out
Eric C. reroofed his house during the summer and, wanting to add solar, first reached out to SunPower because it was highly rated. That initial meeting left him uneasy: the rep avoided detailed answers about how panels were attached, and he discovered they fasten panels to roof studs with screws and then cover the penetrations with a chemlink sealant. His roofer — who was providing a 30-year warranty on the roof — warned that chemlink can allow water to creep under the seal over time and cause leaks, while SunPower’s construction warranty was only 10 years and the rep largely shifted the conversation to electricity savings. Concerned about shortening his new roof’s life, he took his roofer’s recommendation and hired Luminalt instead. Luminalt managed the project from start to finish — design, installation, inspections — so he didn’t have to stay heavily involved, and importantly they install SunPower panels themselves rather than outsourcing the construction. Permitting moved faster than expected: PG&E’s Permission to Operate arrived in under a week instead of the typical couple of weeks, and installers Nick, Kyle and Gen were singled out for professional, attentive work. He even推荐
Niki H. started out skeptical that a high-rated installer could really live up to the hype, but she and her husband chose to pay a bit more for the peace of mind of service after installation. They kicked things off with a thorough Zoom walkthrough that covered what the company would provide, how installation would proceed, and the expected costs and savings, then a project manager visited the house to map out the roof and garage layout. Told the job would take four to five days, they discovered the crew arrived on time Monday, masked, polite, and respectful; at least seven team members worked at the house each day, introduced themselves, and kept the site spotless — no lunch trash left behind, and the crew swept and vacuumed every evening while briefing the homeowners on progress before leaving. What stood out visually was the garage work: electricians left a tidy, almost deliberate-looking installation. The package included solar panels, a Tesla backup battery, and an EV charger, and the team wrapped the whole job in three days instead of the quoted five. The company also handled the city inspection appointment so the homeowners didn’t have to manage permits, and when a light had
Nicolas M. turned to Luminalt after a neighbor-recommended installer stalled on a difficult home solar-plus-battery project — that first company spent months procrastinating, went quiet, and ultimately said they couldn’t find a code-compliant spot for the battery. He reached out to Luminalt, and they dove into the problem instead of backing away. After several site visits, emails, and back-and-forths with DBI, the team identified a clever workaround tied to an apparent code exception, secured pre-approvals from the city and the fire department, and then proceeded with the install. Inspectors from both agencies signed off smoothly. He experienced clear, timely communication and a professional crew; Kyle, Zach, and Gen led a clean, seamless delivery. Nicolas rarely posts reviews, but the thing that stood out — that Luminalt solved the code puzzle, got the necessary pre-approvals, and delivered a fully permitted, inspected battery installation — earned his five stars.

What You Can Expect
Dave had Luminalt Solar install 29 panels on his Victorian in Bernal Heights ten years ago. Over the past decade he’s been thrilled with the installation and with the monthly savings on his PG&E bill. Whenever a problem has come up he emails the company’s service rep, Kayla; she replies promptly and professionally and repeatedly goes above and beyond to fix whatever’s needed. He considers Kayla the best service rep he’s encountered in any business. Ten years later he still rates the experience five stars, and what he remembers most is how fast an email to Kayla turns into a real solution.
RJ had solar panels installed more than a decade ago on an off-grid cabin, and the same company recently came back to add a battery. They walked them through the new setup, answered questions clearly, and handled all the city paperwork even though the property is off-grid. What stood out was the continuity — the installer returned after ten-plus years and took care of the technical upgrade and the municipal red tape, leaving the owner with a simpler, more reliable off-grid system.
On a San Francisco ranch-style home where he’d already entrusted Luminalt with three systems over a decade, Nick F. called them again when he decided to add Tesla Powerwalls to an existing installation. Having completed PV projects elsewhere around the state, he picked Luminalt because they’d consistently improved and still stood out. When Tesla ran into a parts backorder that stretched more than eight months, the Luminalt crew kept him updated throughout the wait, and once the batteries arrived their scheduling and installation ran smoothly — no surprises, no missed appointments. What stuck with him was the combination of steady communication during a long delay and a flawless, on-time install the moment the product finally showed up.
David Baker built a Net Positive house — a home designed to produce more energy than it uses — and ten years ago turned to Luminalt to design and install its solar system. The project proved unusually challenging, but Luminalt worked through the difficulty and delivered a clean installation. The detail that lingers is simple and concrete: a complex system on a Net Positive home was designed and installed by them a decade ago, and he still regards that successful outcome as the defining part of the experience.
Jeremy S. chose Luminalt to install a Tesla Powerwall for his home. The most memorable part of the experience came well after the install: about a year later an unrelated electrical issue popped up, and Luminalt showed up quickly to investigate, confirmed their work wasn’t the cause, and didn’t charge him for the emergency visit. He found the purchase process itself frustrating because getting the Powerwall from Tesla took a long time, but once the unit arrived the installation proceeded smoothly and the system has performed exactly as expected.
Irene had Luminalt install solar on her home four years ago and started out worried because her roof is metal. Luminalt connected her with other customers who had metal roofs, which eased that concern, and the crew completed the job cleanly—without a single dent—and kept her in the loop from signing the contract through final inspection. Her PG&E bill dropped dramatically, from about $300 a month to roughly $20 including gas; some months have been as low as $5, and busier months like around Christmas run closer to $30. After four years, what sticks with her is the intact metal roof and the tiny utility statements that show the real payoff.
Ken Y. had a three-year-old rooftop solar system when one evening a portion of his ranch-style house lost power. He inspected the breakers and found nothing obvious, and because the affected circuit tied into the solar array he suspected the panels might be involved. On a Saturday he rang Luminalt, got August’s number and left a message; August called back within five minutes but wasn’t in San Francisco and arranged for Noel to help instead. Noel arrived in about 45 minutes, ran tests on the breakers, then walked outside and discovered a power line torn at the utility pole and another nearby spot. Noel took charge of the situation, called PG&E on Ken’s behalf to explain the problem, and PG&E arrived later that day to repair the line and restore power. Ken found Noel’s weekend response — coming out quickly for an issue unrelated to the solar installation and coordinating with the utility — the thing that made the experience stand out.
Margarita R. inherited a Luminalt solar system when she bought her house three years ago and recently noticed a "fault" light on the panel. She phoned Luminalt and a technician named Noel showed up after work hours, diagnosed a simple fuse issue and repaired it. When Noel discovered a wire also needed replacing, he returned over the weekend because he hadn’t had the part on his first visit and completed the repair — and they charged nothing for the after-hours/weekend service. She found the whole sequence—from the prompt response to the technician coming back on his own time and not billing for it—unusually reassuring, and wished she could give the company ten stars.
Eric began a solar project for his San Francisco home in April 2013 and waited a full year before writing about the outcome — by June 2014 his system had run flawlessly and he wanted to tell the whole story. From the start the process moved quickly and thoughtfully: after he filled out a form he got a phone call the next day and a rep on the roof within a week. The salesperson measured carefully, asked about household usage and future plans (Eric wanted room for an electric car), adjusted the design and returned a proposal within a week — not the throw-up-as-many-panels-as-possible approach, but a plan tailored to his needs and budget. The pricing matched what he expected after research, and the rep didn’t push anything beyond what made sense. Installation felt almost invisible in the best way. The crew showed up on time, worked quietly and courteously, and treated the house with respect — Eric works from home and carried on speakerphone calls all day, only noticing the team briefly when they drilled mounts. He even found himself missing the crew once the job finished. Back at the office, the team stayed on top of every piece of paperwork: they filed rebates, nudged him politely on
