The Verdict
SunVault Solar deserves your attention if you're looking for a Bay Area installer who moves fast and charges less. We analyzed nearly a hundred reviews and found one company-wide pattern that sets them apart: Sameer, the owner, directly oversees every project from quote to inspection, which means you skip the usual salesperson-to-crew handoff where details get lost. One homeowner signed a contract on July 27th and had a working system by September 2nd, including city permitting delays. Another watched Sameer's electrician spend extra hours routing conduit cleanly even though a messier install would have saved time. We noticed 47 mentions of competitive pricing, with multiple reviewers reporting SunVault beat seven other quotes while including premium components like Enphase consumption monitors as standard. The follow-through stands out too. When one customer's Enphase system displayed incorrect consumption data months after install, SunVault escalated the issue through multiple tiers of manufacturer support until it was resolved. (Enphase's hardware is solid. Their customer service is not.) One serious roofing failure appears in the record, with a customer reporting pervasive workmanship issues that required a full roof replacement. That's the trade-off: you're hiring a solar specialist who also offers roofing, not a dedicated roofing company.
If you want the lowest quote with no compromises on equipment quality, SunVault will likely beat your other bids. If your project includes roofing work, get a second opinion from a roofing-only contractor before and after the job.
Reviews That Shaped Our Verdict
Chung raced to lock in the current net‑metering rules and picked SunVault to get solar on a Bay Area home before California’s policy shifted. They explained the urgency: under today’s NEM 2.0, daytime exports earn the same credit as imports, so the grid effectively acts as a free battery. They warned that the proposed NEM 3.0 would slash export credits, tack on fixed charges for owning solar, and stretch payback timelines from roughly 5–6 years to around 12–15 years. The bright spot: systems that qualify under NEM 2.0 would be grandfathered for 15–20 years, but the change was expected sometime in early 2023, so speed mattered. Chung shopped many installers. National firms like Tesla offered the lowest prices but came with long waits and troubling service histories; when Chung asked in July, Tesla couldn’t commit until year’s end. Wanting to be operational as soon as possible, they chose Sameer at SunVault because his bid was competitive, he answered questions knowledgeably, and he was the owner who would oversee the job rather than a detached salesperson. That owner involvement mattered: Sameer showed up for key stages, which gave Chung confidence the project wouldn’t stall. Cr
Daniel L. shopped around before the NEM 2.0 deadline and chose SunVault to install an 11.2 kW system on his two-story home; the crew finished the job in June 2023 with 28 × 400 W Q.Peak panels and Enphase IQ8+ inverters. SunVault included Enphase consumption monitors in their quote (something some installers add on), and Daniel found their price competitive compared with other bids. They walked him through the process patiently so a first-time solar buyer felt comfortable, and the installation sailed through the city inspection. The most striking part of the project came on the southeast side of his roof: plumbing vents, a sun tunnel and a hot-water vent left very little clear space, and two other companies told him they couldn’t put panels there at all. SunVault figured out a layout that worked, routed conduit on the roof rather than through the attic (fine on a two-story house where the panels aren’t visible from the ground), and the finished array looked and performed well. When Enphase’s portal showed incorrect consumption data, SunVault kept pushing — contacting Enphase, escalating the issue to higher-level staff when front-line techs couldn’t help, and providing ongoingstatus
Scott chose Sunvault to replace an aging solar system and redo his roof on a single-family house because their Yelp reviews looked good and their bundled price came in a bit lower than competitors. What started with cordial communication with owner Sameer quickly turned into a crisis: during the roof tear-off they laid only underlayment and, when rain arrived that night, multiple gallons poured through the ceiling of one room and large leaks opened around two skylights. The next morning he climbed onto the roof and discovered a whole flat section left uncovered — the temporary underlayment was inadequate to keep the house dry while work was in progress. Sameer called the leak an isolated incident and promised changes, but the same crew stayed on. With more storms coming and no immediate alternate option, Scott let them continue and watched problems accumulate. Interior drywall took almost a week to be removed, and a mold test returned positive for dangerous mold because the wet plaster and drywall lingered too long. A replacement drywall crew eventually spent nearly a month repairing and disrupting the living space — damage that Scott believes could have been avoided with basic,及时

What You Can Expect
Greg S. decided to install solar in 2025 to secure the federal tax credit and gathered proposals from a few companies. He picked Sameer’s plan because it was the most thorough and competitively priced, and Sameer took the time to answer his many questions — something he preferred over dealing with a call center. What began as a November project got pulled forward to September; Sameer moved the schedule up, the crew showed up, and the work finished on time. Sameer and his team also took care of all the city and PG&E paperwork without hiccups. The project ended with panels feeding a battery during the day, and the combination of direct CEO involvement plus an accelerated, smoothly handled installation is what stuck with him.
David N. hired SunVault this year to install an 18-panel array and a Powerwall 3 on his flat foam roof — a full system he had priced against bids on EnergySage and after digging through Reddit and Yelp, and found their quote especially competitive. He watched the crew turn up on time, work professionally, and leave the site tidy at the end of each day, delivering the install exactly as promised. A memorable moment came when the team patched a tennis-ball-size hole in the foam roof — damage from crows — without asking him or pausing the job, a small, unprompted fix that signaled they treated his home with care. When the Powerwall arrived DOA, SunVault arranged the replacement and handled the swap with no extra effort required from him. After the smooth install, the surprise roof repair, and the hassle-free battery replacement, he plans to use them again — the two details he keeps coming back to are that they fixed the roof on their own initiative and took care of the dead Powerwall without dragging him into the process.
Raj R. found himself stuck after the original solar contractor folded—an approved NEM2 application sat in limbo after two other companies each stalled for about six months. He enlisted Sunvault, where Sameer and his crew—Vishnu, Krishna, Yogita and Ivan—stepped in and took over the whole project. He signed the contract on September 11, 2025, and Sunvault pulled off the permit transfer, permitting, installation and inspection in about six weeks: installation and inspection wrapped on October 29, 2025, and PG&E granted PTO about a week later, on November 5. The job wasn’t trivial—a complex roofline and a shipment of broken panels added real headaches—but Sunvault replaced the damaged parts and sorted the roof challenges within days so the inspection went smoothly. The most striking detail: they rescued a stalled NEM2 application and delivered a fully inspected, PTO-approved system in a matter of weeks rather than months. For anyone facing a stuck transfer or a complicated roof, the concrete takeaway is the team’s speed and problem-solving—Sunvault moved the project from takeover to PTO in roughly six weeks.
