Xero Solar reviews

The Verdict
We recommend Xero Solar without reservation. In one standout story, a customer with a broken inverter called the company that originally installed her system and waited months without a callback. She borrowed a friend's Xero contact, and someone showed up within days to inspect the inverter and quote the repair, even though Xero hadn't installed it. We found that kind of follow-through again and again. Nobody mentioned waiting more than a couple of days for a response. Thirty-four reviewers mentioned the installation quality, and not a single one had a complaint about the workmanship. One customer described the team plotting every wire run and conduit piece with "incredible attention to detail," noting that "good enough" wasn't in their vocabulary. (Yes, someone actually gushed about conduit placement. Solar brings out strange passions.) The company handles all utility paperwork, rebate filings, and permit coordination, so you won't spend weeks navigating SoCal Edison's bureaucracy yourself. One system has been running for a decade with zero power bills, aside from occasional warranty repairs that Xero handled proactively.
If you want the absolute cheapest quote, keep shopping. But if you want an installer who'll show up years later to troubleshoot a competitor's broken inverter, or reimburse you when their office makes a rebate filing mistake, Xero Solar is worth the premium.
3 Stories That Stood Out
Rebecca P. began the process for a 12-panel system plus a Firewall for a recently purchased home, after sampling online quotes and leaning on a friend's referral to contact Xero Solar. She waited on Derek's advice to move forward until they had nearly a year's worth of usage — especially since air conditioning was coming — so the team could size the array accurately rather than sell more hardware than made financial sense. When she restarted talks to capture the year-end federal tax incentive, Derek walked her through why upsizing would hurt the return and how financing versus paying cash would change the payoff, and she opted to proceed. Xero coordinated with her roofer to protect the roof warranty, handled all SoCal Edison paperwork, permits, and the SGIP rebate, and kept interactions polite and helpful throughout. A couple of months after installation they proactively flagged a fault in the LG communications module, sent a tech, and replaced it under warranty. Rebecca contrasts that with a friend whose inverter problems dragged on for months with another installer; after Rebecca passed along Derek's contact, Xero inspected her friend's system, gave an honest cost assessment, and
Elliot T. hired Xero Solar to install roof-mounted panels and the supporting electrical work at his home and watched the crew patiently plan every move before starting. He found the installers painstakingly neat and exact — tidy runs of rigid conduit, outlet bodies, junction boxes, flex and wiring placed precisely where they belonged. Their attention to detail felt almost obsessive; for them the phrase "good enough" simply didn’t apply. Beyond craftsmanship, he noticed that the crew were genuinely friendly, and the project manager and office staff were consistently helpful and quick with answers. He walked away most impressed by the combination of polish and responsiveness — the job looked like it had been measured and executed to last.
Nancy N. hired the company to install solar panels and a battery on a house that was still being built, and what stood out most was the owner Ben’s integrity. Early in the job a clerical error from Ben’s office — initially thought to be a simple fix — snowballed into a year-long complication during construction. Ben and his team tried to straighten things out, and ultimately he emailed them to offer to “make them whole” by reimbursing the rebate they would have received if the paperwork had been handled correctly. She and her husband were floored: after dealing with other contractors who had been incompetent, dishonest, or lazy, this felt unusually responsible. They haven’t used the solar or battery yet because the house isn’t finished, but her husband has been the main contact with Ben and praises his business practices. Ben’s crew also struck them as extremely courteous, professional, and prompt — a reflection, she believes, of the owner’s standards. Aesthetic details mattered to them as well: the panels have a sleek, low-profile finish that matched their request to avoid anything bulky, and Ben delivered. Their architect, Larry Peha, who does a lot of work in Hermosa and on by

What You Can Expect
Robert’s experience stretched well beyond a simple installation review, because the system went in back in December 2020 and then kept proving itself over the years. What stood out most was how Xero handled the whole project as a single, coordinated job: George B. stayed involved from the first sales meeting through permitting, utility approvals, rebate paperwork, and the installation itself, giving the kind of continuity that matters on a big solar-and-storage investment. Robert and his wife initially had to correct the assumption that they wanted the cheapest possible setup; what they really wanted was maximum backup power if the grid failed, with lower bills as a bonus. That led to a larger system than a basic bill-saver: 40 panels, 4 Tesla Powerwalls, and the supporting equipment needed to make it all work. The pricing landed where they expected, and the project moved fast, even while their roof was being replaced at the same time. Xero coordinated the panel hardware so the roofers could seal everything properly, and the solar installation finished on schedule. Over time, a few problems did surface — one LG panel failed and was replaced, one Powerwall began tripping because ofa
Lisa Toman chose Xero Solar for the rooftop system on her new-construction home, and the array has been operating for more than a year. She worked with Riley and the Xero Solar team, who kept her updated on scheduling and delivered a prompt, efficient installation. The package felt affordable to her, and after a year she’s noticed lower utility bills that make the upfront investment easier to accept—especially since solar was required for the build. The clearest takeaway: clear communication and a quick installation turned a required expense into tangible monthly savings.
Joseph had Xero Solar install a system on his home about ten years ago, and it still keeps his electricity bill effectively non-existent. Over that decade he encountered a few technical hiccups—repairs covered under warranty and some software updates—and Xero handled those issues without fuss. He recently cleaned the panels (something he wishes he'd done sooner) and saw an immediate uplift in production. The team stayed helpful throughout; Riley and Maki stepped in whenever he needed assistance. After ten years of mostly trouble-free output and responsive service on the few problems that came up, he still tells friends about Xero Solar — the clear takeaway being that routine cleaning boosts performance and the company stands behind its work.
Preston McAfee chose Xero Solar to install a solar system on his home, received a fair estimate, and discovered the workmanship was top-notch. The crew carried out the installation professionally, and two years later he hasn’t had a single issue—everything continues to run smoothly. The detail that stands out is the durability: high-quality installation that delivered trouble-free performance well after the job was finished.
Robert B. walked away extremely satisfied with Xero and their representative, Lee Rhoads. He found Lee patient through the design process — taking time to work through placement and system choices for the house — and the company delivered when they promised: on schedule, at the quoted price, with no hidden fees. When a placement decision came up during installation, he was about to call for guidance when Lee showed up on site to check progress and help decide, a level of hands-on responsiveness that stood out. A year after the system activated he needed to move the computer used for output monitoring; Xero rewired the connection at no charge. The detail that stuck with him was the combination of Lee’s timely on-site support during installation and the free follow-up service long after the sale.
Elliot hired Xero Solar for a residential solar and electrical install and watched the crew methodically plan every step. He noticed they took their time, kept the site impossibly neat, and treated each task with meticulous care — from placing rigid conduit to mounting outlet bodies, junction boxes, flex and wire, everything landed exactly where it belonged. For this team, "good enough" wasn’t an option, and their attention to detail was the single clearest takeaway. The installers were personable throughout, and his project manager and the office staff fielded questions quickly and helpfully. He left a five-star review and ended up with a clean, precision-installed system; the exact placement of conduit and j-boxes is the detail he still points to.
Terri ended up in a frustrating spot a year after her Tesla Powerwall installation, when her SCE bill suddenly started climbing and the utility brushed her off after a lot of wasted time. Looking for any way to untangle the overcharges, she turned to Xero Solar and first connected with Rhetta, who stayed on top of the problem, kept in touch, and pushed until the issue had an answer. Rhetta then brought Tina in to contact SCE on Terri’s behalf, and the two of them managed something Terri hadn’t expected at all: they negotiated a refund for charges that never should have been added. What stuck with her was that Xero Solar stood behind a system installed more than a year earlier and still fought to make SCE put the money back.

John W. went into a residential solar install in Southern California and found Xero Solar outstanding from the first intake conversation through project completion. He experienced steady, clear communication and a team that was quick to respond and resolve questions, which kept the installation moving smoothly. Pricing felt reasonable, the timeline stayed efficient, and the job finished with a functioning solar-plus-backup setup. He ended up more energy independent and largely freed from those expensive SCE bills — the combination of fast, attentive service and a working backup system is what he keeps coming back to.
