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

Brian needed a system installed before the Dec. 31 deadline and called for a quote. He landed a competitive proposal from Thomas, and with Abdullah managing the project the company drew up the contract and completed the installation in six weeks. The crew fitted high-quality solar panels paired with a Tesla Powerwall, and he expects his PG&E bill to drop to a fraction of last year’s cost. What stuck with him most was the rapid six-week turnaround combined with the Powerwall backup.
Camella answered a cold-call about solar and, curious because the pitch felt different, invited the team to evaluate her home with its unusual roof needs. Kerrie walked her through tailored panel options and different service levels so she could choose the exact equipment and coverage that fit the house. Because the company also does roofing work, they handled the roof complications directly rather than handballing them to another contractor. Mei kept the project moving, coordinating details between sales and the installation crew so decisions and schedules flowed smoothly. The installation crew arrived respectful of the property and worked efficiently, and the system includes batteries on site so excess power will be sold back to PG&E each month. After speaking with many companies over the years, she ended up with a roof-friendly, battery-backed setup and a plan that should deliver monthly savings — the combination of roofing expertise plus a single point of coordination is what made the difference for her.
E Z. walked into Solar Sesame’s Hayward office to pay the final balance on a system that’s scheduled to be delivered and installed on December 29. They stepped into a staff meeting—about 14 people in the room—and found everyone professional and genuinely welcoming, which quickly reassured them about how the company operates. The planned install includes 13 solar panels, one Tesla battery and a universal car charger; they plan to share photos as the project moves forward and are eager to see the system live. Having just added air conditioning, they already noticed a significant drop in their PG&E bill over the summer and expect the new solar setup to reduce bills further. What stuck with them most was the bustling, engaged 14-person team—a clear sign they’ll be in good hands on December 29.
Racing to lock in incentives before the credits expired, Prateek set up a meeting with Kerrie from Solar Sesame and discovered right away she was both professional and personable — they even swapped tips for easing back pain while discussing the system. He experienced a smooth, on-schedule installation that unfolded without hassle; the project manager stayed in close contact, answered every question promptly, and kept the timeline moving. Inspections and the final permission to operate came through quickly, so the array became operational without delays. What stuck with him was the combination of that personal touch from Kerrie and the fast, well-managed process — the kind of straightforward, timely installation he would point others toward.
Ross R discovered a solar company that took charge of everything required to get his system up and running. He felt genuinely blessed by how smoothly the process unfolded—no need to hunt down paperwork or manage the details himself. Because the team handled the full installation journey, he ended up with a working system and the confidence to tell all his friends about them.
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.
Jerry Arias moved forward with a residential solar install after SolarSesame’s Instant Credit Promotion made the numbers immediate and compelling. He received the 30% Federal Solar Tax Credit at the time of purchase instead of waiting for next year, which sealed the deal. The crew finished the job quickly and efficiently, arriving on time, working with care, and leaving the house spotless. The system started up without issues, and he’s already seeing at least $100 shaved off his monthly electric bill. What stood out most was walking away with the tax credit in hand and an operational system that began delivering real savings right away.
Paul M. discovered a leak in his kitchen directly beneath the rooftop solar array — an urgent problem that took precedence over everything else. He reached out and local reps Andrew and Nema moved quickly: Andrew made contact and Nema arrived as scheduled to patch the leak. They also addressed connection problems, but questions remain about the battery’s usage and a subsequent PG&E bill. A permanent repair to the roof and several outstanding discrepancies still need to be scheduled and resolved. Because of the prompt emergency response he added two stars to his rating, and he will consider raising it to five once the permanent fix, billing reconciliation, and paperwork issues are fully settled.
Puthea began a panels-and-batteries installation after a brisk sales pitch, but the project still sits unfinished and has been punctuated by repeated missteps. They discovered the sales claim that “everything is done in-house” wasn’t true — the crew who actually installed the equipment were subcontractors driven in from hours away, which seemed to contribute to muddled coordination and crews unfamiliar with San Jose building code. Communication inside the company and with Puthea felt disorganized: she checked the city’s inspection calendar and found a different date than the one Solar Sesame had told her, forcing her to reconfirm the appointment. A bigger problem came when installers were due between 8:00 and 8:30 a.m.; after repeated calls and mixed messages from the project manager, the team never showed, the city inspector left, and Solar Sesame blamed an emergency — a missed inspection that pushed the schedule back weeks. At another point a subcontractor arrived unannounced to make corrections while the company had no record of him being there. The rough-frame inspection has failed three times for different reasons, and the company has blamed stringent city code rather than the
