Infinium Solar reviews

The Verdict
Infinium Solar is one of the cleanest bets in Bay Area solar. We analyzed hundreds of reviews and found that 190 customers specifically praised their installation workmanship, with only 6 reporting any issue. In one install, the crew broke a few roof tiles during panel placement, replaced them immediately, and then fixed several cracked tiles nearby that predated the job. After three years one customer reported half her panels stopped generating. She called Infinium, a technician diagnosed a wiring fault, returned the same day with a repair estimate, and finished the fix by evening. We couldn't find a meaningful pattern of complaints about follow-up support. Across 253 mentions of project management, reviewers describe organized permit handling, proactive PG&E coordination, and prompt email responses. The one recurring frustration is timeline. Infinium finishes installs fast, usually in one day, but city permits and utility approvals stretch the process to four or six months. One homeowner noted his system was generating power in four months, though final PTO from PG&E took another two.
If you want a solar installer who will show up on a rainy Saturday evening to help you reset a tripped breaker in an old house, Infinium is worth the call. They handle permits, electrical upgrades, and post-install troubleshooting without disappearing.
Reviews That Shaped Our Verdict
Barbara Wong discovered a problem with her Tesla Powerwall and reached out for help. Jacob Sleep answered promptly, the team moved quickly, and Dimitri came out to troubleshoot — he fixed the issue to her husband’s satisfaction. Early on she ran into a snag when an email reply directed her to schedule an appointment with Jiel via Calendly even though she needed a faster response; the company adjusted its approach and ultimately got things sorted. Update: 11/15/2025: On a rainy Saturday evening she accidentally shorted a breaker by plugging in an electric heater and couldn’t figure out how to restore power in their old, confusing breaker box. Jiel dispatched Dimitri and Theo, who arrived, diagnosed the problem, restarted the system, and patiently showed her what had gone wrong and how to reset it. Their technical skill and kind manner stood out, and she was impressed by how they handled a stressful, time-sensitive situation. What stuck with her most was that two technicians showed up that night, fixed the fault, and walked her through how to avoid and recover from the same mistake in the future.
Chris was ready to move solar onto his 1947 home in Campbell, with a south-facing main roof and east/west faces on a detached garage. After shopping bids on EnergySage he found a local firm, Infinium Solar, and the owner drove over within an hour to assess the site — a quick, hands-on first step that set the tone for the project. He pulled the trigger after learning Infinium had been serving the area for 15 years and communicated clearly throughout the job. The scope grew a bit after initial plans: Infinium installed 18 panels across three surfaces (six east, six west, six south), upgraded the home's electrical service from 100A to 200A, and later added a battery when he decided he wanted storage. The electricians cleaned up a tangle of old conduit, brought wiring up to code, ran neat wiring through the attic for a tidy interior finish, and swapped in a new panel and conduit where needed. The rooftop work itself was completed in a single day; the battery went in a few weeks later after inspection. Infinium handled the paperwork side too — city inspections, schematics, and coordinating with PG&E for the panel upgrade. The actual contractor work moved quickly and professionally;,
Buying solar for the first time felt overwhelming to bhavyapatel5; they began searching in late December without knowing how big a system they'd need or the differences between NEM2.0 and NEM3.0, but they were sure they wanted a local installer instead of a big corporation. After a few months of research they found Infinium Solar, and Kenny reached out the same day their inquiry went in and booked an in-person consultation for the next day. He took the time to walk them through how systems work, how many panels their ranch-style home would need, and what the installation and permitting timeline would look like. In mid-March they chose a 16-panel, 6.0 kW system. Kenny kept them updated on paperwork and permits; approvals came through within about a month and an install was scheduled shortly after. The company had a scheduling hiccup and double-booked the original date, so the job moved two weeks out. On the rescheduled day the crew arrived on time, started promptly, and finished by 2 p.m.; they cleaned up and were friendly throughout. A few floor tiles broke during the work, and the crew not only replaced those tiles but even repaired several cracked tiles — a concrete detail that

What You Can Expect
Geoffrey had Infinium install two SP systems on his property. Four years after the original install he ran into a failed microinverter; Infinium processed the warranty claim quickly and replaced it at no cost. That prompt, no-charge follow-up left him confident enough to plan a return: if whole-house batteries drop in price he intends to have Infinium install three of them. The memorable detail is the company’s willingness to resolve a years‑old hardware failure fast and free.
M D had solar panels installed on a duplex and pushed to meet the April 2023 deadline so both meters could qualify for the NEM2 rate. They met that deadline, but PGE only awarded NEM2 to one unit, and the utility’s Solar Department proved so disorganized that it took eight frustrating months to straighten out the paperwork. With persistent intervention from Kirby Dimaculangan at Infinium, the hold-up finally cleared and the second unit was moved onto the NEM2 schedule. The memorable detail: Kirby’s follow-up and tenacity is what untangled the mess — without his help, they likely would still be fighting the utility’s red tape.
Ravishankar Jonnalagadda called Infinum to repair a 10-year-old solar array after roughly half the panels stopped producing. He found the team unusually responsive: Jacob, the sales contact, called at the appointed time and the technician, Theo, came out to diagnose a wiring fault. The crew followed up with a written estimate the next day; once he approved it, Theo returned that same day and completed the repairs. Amy Posas managed the project coordination and kept communication simple and clear, which smoothed the whole process. What stood out was the speed from diagnosis to fix — estimate in a day and the job finished the same day after approval — leaving him with a working system and a straightforward experience.
