Solar Sesame can deliver a working solar system, but the path from contract to power-on is littered with avoidable problems. In one Hayward install, panels went up fast, then the battery hookup dragged six months because the crew installed gear in the wrong spot (failed inspection), scheduled inspections the same day they planned to finish work (no buffer for delays), and handed over a non-functional system before testing it. The verdict shifted only after the homeowner posted a one-star review. We found 18 reviews flagging missed appointments, subcontractor miscommunication, and repeated inspection failures. One San Jose customer watched a no-show crew miss a city inspection window (pushing the project back weeks), then discovered the subcontractor arriving unannounced days later while Solar Sesame's own project manager had no idea anyone was on-site. The company failed that home's rough-frame inspection three times for code violations, despite operating in the Bay Area for years. When things go smoothly (55 reviews describe seamless installs and immediate savings), consultants like Kerrie and Marcel earn praise for patience and transparency. But the pattern suggests Solar Sesame overbooks, then prioritizes only the work it's contractually obligated to finish quickly.
If you prize predictable timelines and proactive communication, look elsewhere. If you're willing to negotiate contract deadlines for every phase (not just panel mounting), stay on top of inspection schedules yourself, and escalate loudly when promises slip, you may eventually get a functioning system at a competitive price.
Jonathan chose an up-front purchase of Q-Cell panels and batteries for his Hayward home and worked with Dan and Carrie to design exactly the system he wanted. The roof crew showed up and mounted the panels quickly and efficiently — the one part of the job that moved fast because it was contractually required. The trouble began with the battery and power-electronics installation and the push to get everything inspected and cleared by the city of Hayward and PG&E. A string of SolarSesame errors plus limited inspector availability stretched that phase to about six months. They installed the equipment in a different spot than agreed, which failed inspection, forced a relocation to a code-compliant location and left cosmetic damage as the work area got moved. Crews repeatedly booked inspections for the same day they expected to finish, leaving no buffer when inevitable issues popped up. The team also handed the system over before confirming it worked properly; ensuing fixes were needed until Andrew diagnosed and resolved the problem. When Mei was reachable by text, she was knowledgeable and kept the process moving; other contacts were apologetic but less useful. After Jonathan lefta
Puthea began a panels-and-batteries installation for a San Jose home and quickly discovered the fast sales pitch didn’t match reality. They felt misled when the company claimed to handle everything in-house but sent subcontractors from several hours away — crews whose unfamiliarity with local San Jose code seemed to drive repeated problems. Communication unravelled early: the company gave an inspection date that didn’t match the city’s record, forcing Puthea to check the city website and reconfirm. On the day of a scheduled inspection the crew was supposed to arrive between 8:00 and 8:30 a.m.; by 9:45 a.m. Puthea was asking where they were, and the project manager kept saying she would get back. At 11:15 a.m. the manager told Puthea the team was already on site — they weren’t — and the city’s inspection window (10 a.m. to noon) passed with the inspector leaving without approving anything. Solar Sesame later changed its explanation to an emergency, but those missed windows pushed the project back by weeks. Worse, a subcontractor showed up unannounced to make corrections while Solar Sesame’s office seemed unaware the crew had arrived. The installation has failed the initial rough
Steve B. had a large, south-facing roof and hired Solar Sesame to fill it — they put up 27 panels and a Tesla Powerwall with just over 10 kWh of storage. By September 2025 he watched the array produce more than 8.5 kilowatts at midday, with morning sun topping up the Powerwall, afternoon generation exporting energy to PG&E, and stored power covering the house overnight while the system stayed connected to the grid for any shortfalls. The practical effect hit his pocket: during Sept–Nov 2024 his PG&E bills ranged from about $660 to $930, but after production began in Sept 2025 his bills never exceeded $160 for the same period. He now pays Solar Sesame a fixed monthly payment of roughly $340, and expects the value of on-site generation and storage to keep rising as utility rates climb. The one real downside was time: he signed the contract in August 2024 but didn’t see production until September 2025 — delays driven by permits, multiple contractors, Tesla supply, and high demand for installers. As an electrical engineer he accepted the slow timeline, and ended up with a dramatic drop in utility bills paired with a home battery system — a clear payoff, if buyers are prepared to wait a

David began as a skeptic in San Francisco, staring down an $800-a-month power bill and wondering if the offer was really as good as it sounded. The company handled the whole solar journey for him, from permits and inspections to the final handoff, with a friendly, professional crew and no upfront money required. What convinced him was the pricing: a competitive kilowatt rate that cut his monthly bill to about a quarter of what it had been. Now he checks the status in the Tesla solar app and watches his home move toward life off the grid, with every step of the process wrapped up cleanly on their end.
Brian was racing the rainy season while also trying to juggle a full roof replacement, new solar, and a heat pump swap on a house with hefty electric demand. That meant a big project: a complete tear-off, new plywood, and panels that had to come together fast. He had already looked at Solar City, but that quote stalled because they couldn’t coordinate with a roofer, and their leasing terms felt off to him. Solar Sesame took a different approach. Marcel walked him through the process clearly, and when Brian pressed with detailed questions, he didn’t bluff his way through anything he didn’t know — he checked with the office and came back with solid answers. The roofing side was handled by Arts Roofing, and despite Brian’s initial hesitation about using a vendor, that choice turned out well. The crew communicated well, handled a small issue professionally, and kept the job moving. The panels went up quickly, the system started producing power right away, and the only real delay came from PGE dragging its feet on the final inspection. Even then, Brian didn’t start paying until after the utility completed the final turn-on. He now tracks production in both the PGE site and the Tesla app
Rob had already spent too much time going back and forth with Tesla on service and design before turning to Solar Sesame, and the difference showed up quickly. His project moved like a true turnkey job, with sales, project scoping, design, electricians, installer crews, technician checkoffs, and commissioning all handled under one roof. Mei, his project manager, stayed highly responsive throughout, and the technicians and installers were just as easy to reach when questions came up. A few hiccups surfaced along the way, but they were sorted out without derailing the job. Solar Sesame also took care of the city permitting and filed the paperwork with PP&E to sell his excess power, sparing him the headache of figuring out the utility website on his own. In the end, he ended up with Tesla battery storage and REC panels that felt like a solid value, plus the rare relief of not having to untangle the net-metering paperwork himself.
Bob came to Solar Sesame after a rough Tesla design-and-service ordeal, and the difference was immediate. Mei, his project manager, stayed responsive and helpful from start to finish, and the technicians and installers kept the communication moving too. What stood out most was how fully handled the job felt: they scoped the system, worked through design and permitting, managed the install, and got the commissioning completed as a true turnkey process. A few minor scheduling hiccups came up along the way, but they were sorted out without derailing the project. Solar Sesame also took care of the city permitting and the paperwork needed to sell power back to the grid, while his Tesla storage batteries and REC solar panels ended up feeling like solid value for the money.
Zen ended up with a solar panel system and two EV chargers on his property, and the standout part of the experience was how well the team kept him in the loop while the project moved through the slower city and PG&E permit and inspection steps. Mei and her crew stayed in touch the whole time, giving him updates on where things stood and how the installation was progressing, which made the wait easier to take. Once the equipment was in place, he felt good about the competitive price and the long-term value he was getting for years ahead. The result was a home set up to ride out the next PG&E outage without being left in the dark.
Philip did his homework and chose Solar Sesame for a residential solar system with a backup battery, expecting the company’s promised two-month install and commissioning timeline. Instead he watched the project stretch to nearly six months, and neither the solar array nor the backup battery became operational. Work repeatedly stalled: crews failed to complete tasks on time and often hadn’t finished required work before scheduled inspections, so the inspector couldn’t sign off. Every delay traced back to the installer, leaving him months past the original schedule without a functioning system — the standout fact here is that a job sold as a two-month turnaround ended up almost tripling in time with no working equipment to show for it.
Elisabeth only got movement after posting her review, when the company finally came out to her home and addressed the lingering problems with her solar setup and Tesla battery. The most concrete fix was the breaker: despite the company insisting the incompatible part was never a safety issue, even after a city inspector, an electrician, and online research had pointed the other way, it was replaced. They also dug into the battery trouble and landed on a theory that a missed firmware update on the meter collar might be behind it, though that explanation still hadn’t been proven on her end. What stuck with her as much as the technical back-and-forth was the tone of the follow-up, which she found dismissive and condescending, with the owner and service rep pressing her to take the review down while she waited for the battery issue to be confirmed and her incentive paperwork to be finished.
John compared quotes from three or four solar vendors for a home solar-and-battery setup, and Solar Sesame stood out immediately for the way it handled the process. The team kept communication clear, laid out the details transparently, and stayed on top of follow-up better than the other companies he considered. When installation day arrived, the work moved fast and was wrapped up efficiently, leaving him with a system installed without the drawn-out hassle that often comes with these projects.
Duane signed on in 2025 with a promise that made the deal feel time-sensitive: if he got the contract in before October 15, the company would have a full solar installation finished by year’s end, and if it missed that deadline, a Tesla Powerwall would be the make-good. He even had multiple conversations with the manager, who reinforced that commitment. The process looked normal at first, with an initial inspection happening quickly, but after that the project started to unravel. The company missed the deadline to submit the application to MID, leaving Duane to keep calling and emailing the utility himself just to learn that nothing had been filed for his address. When the paperwork finally went in, the payment was short by $200 from what MID required, and he was even asked to make the payment himself with a promise of reimbursement later. By the end of 2025, the roof still had no solar on it, and the promised Powerwall had turned into another dispute, with the company blaming delays on circumstances it called beyond its control while giving him shifting explanations for why it would not honor the original agreement. He was left weighing legal action after a year that produced a on
