Semper Solaris reviews

The Verdict
Semper Solaris leaves too many customers stranded when systems fail. We found over 200 reviews describing the same pattern: months-long delays for basic repairs, project managers who vanish mid-job, and warranties that turn out to be meaningless when you actually need help. One homeowner paid $55,000 for an off-grid setup with two Tesla batteries, waited two years for installation, then spent seven days trying to get anyone to jumpstart the dead batteries while a hurricane approached. Another family started their solar project in September, watched workers fail inspections for forgetting to install equipment they left sitting in boxes, and still had no working system 15 months later. The workmanship scores look decent until something breaks, then the support infrastructure collapses. When you need a roof repair, they quoted one customer 35% above market rate and refused to remove panels unless he paid their inflated price. The company relies heavily on named staff praise in positive reviews, but the negative ones reveal a coordination breakdown where Eric doesn't know what Ameet promised and Jennifer has no record of either conversation.
If you want solar panels that work flawlessly from day one and never need service, you might skate by. But the moment you hit a problem, whether it's a dead inverter, a roof leak, or a failed inspection, you're gambling on whether anyone will call you back this month. The 200-plus reviews describing ghosted repair requests and year-long installation timelines aren't outliers. They're the system working as designed.
Reviews That Shaped Our Verdict
Logan went into this as an attempt to run his ranch in San Diego County off the grid — a $55,000 solar system built around two Tesla batteries. He ended up with a system that took two years to complete, riddled with county permit headaches, repeated mistakes and constant delays, and despite the big outlay he still pays about $200 a month for electricity. The panels will carry the house on sunny days for a stretch, and he finally received a $5,000 rebate after the long slog, but both Tesla batteries died before Hurricane Hillary arrived and Semper Solaris has been slow to respond. He has been waiting days just for a technician to call back about jumping the batteries, has run into stalling “process” explanations at every turn, and has grown convinced the original salesperson misled him. He reserved praise for the install crew and the battery support techs, who treated him kindly and patiently while trying to fix the mess, but the overall experience left him furious — especially given the company name invoking the Marines. With 43,000 followers and millions of views online, he’s ready to escalate, wondering whether he’ll have to hire an attorney to force a company technician to come,
Laura Hilliard began a residential solar installation with Semper Solaris about 15 months ago and still does not have functioning solar on her home. She watched the project stretch from a September start to equipment arriving only in June, then stall for months with repeated gaps in communication and at least three different project managers cycling through the job. Early follow-up came when Bob King contacted her husband, but months later nothing is operational. Inspectors failed a county inspection last Friday and the first anyone told her husband was the next Tuesday; the company blamed a missing fire inspection even though one had been completed in July. Installation crews left a worker sitting in his car for two hours waiting for a fire inspection, another waiting two to three hours for a county inspection, and at least one box of supplies was opened at inspection with the parts still uninstalled—her husband even photographed the uninstalled equipment and posted it a month ago. During the installation crews ripped through a wall into the kitchen, appointments were missed without notice, and on the latest no‑show they texted at 1:30 p.m. to say they wouldn’t come. Tired of lost
SK chose Semper Solaris in late 2020 partly to support a veterans‑owned business, and installed a rooftop solar system on a suburban home. They discovered activation dragged on for five months and crews left beer bottles in the trash—an early red flag that was followed by larger problems. At installation they were told an uninstall/reinstall would cost $35 per panel if roof work was needed later, but nobody clarified that the price or service might be conditioned on using Semper for the roofing itself. When heavy rains in February 2024 produced a roof leak, they reached back out to Semper. Semper quoted what SK calls an astronomical price for the roofing, then negotiated a figure for the panel uninstall/reinstall on the assumption SK would use an independent roofer. SK then found a contractor offering the same product and warranty at about 35% less. When SK asked Semper for the uninstall/reinstall contract so the outside roofer could proceed, Semper reversed course—refusing to perform the panel work unless SK agreed to have Semper do the roof. Calls and messages produced no real answers; staff responses contradicted one another (Eric, Ameet, and Jennifer appeared out of sync), SK

What You Can Expect
Nancy trusted Semper Solaris to overhaul her ranch-style home a few years back, installing solar panels, a heat-pump HVAC system, and a new roof and gutters. She discovered the company didn’t stop at the install: routine follow-up support kept the systems running and made future upgrades feel straightforward. When she decided to add a battery recently, the same consultant, Mark Ivory, returned to walk through options—clear presentations, patient answers to a lot of questions, and plainspoken guidance that made choices easy. She valued that continuity: the person who helped choose the original systems showed up again and knew the house and equipment. Beyond the individual, she settled on Semper Solaris because the company has longevity and stands behind warranties and service, and she found their customer service unusually attentive and reliable. The detail that stuck with her most was having the same knowledgeable consultant available years later—an assurance that made warranty and follow-up care feel secure.
Russ Edwards pursued a complicated solar upgrade: his original array, installed more than ten years ago, needed to stay connected to the grid at favorable export rates while a new battery-backed system got added alongside it. He found that the tentative layout Jon the salesman sketched matched what the design team produced, so the install moved forward smoothly. The crew, led by Nic, handled a tricky, dual-system roof job professionally and finished on schedule. At first the two systems didn’t behave as intended, but Jon pushed the issue up to Semper’s technical team and got the software settings corrected — something Enphase couldn’t resolve despite several conversations. Throughout design, installation and commissioning, Jon answered questions almost instantly (often within minutes) and steered the fixes. In the end Russ ended up with a functioning, split setup that preserves the legacy system’s export benefits while adding modern, battery-backed generation — and a memorable level of responsiveness that kept the project on track.
Molly W. turned to Semper Solaris in 2020 and has relied on them for two major solar, electrical and roofing projects on her home. She found the team consistent and capable across trades, but the most memorable moment came when a connectivity hiccup—her error, not the company’s—needed fixing. Linda C. stayed on the line, walked her through the troubleshooting step by step, and proved deeply knowledgeable, dependable, conscientious and patient. That hands-on follow-through for a user-caused problem is the specific kind of aftercare that convinced her Semper Solaris is a reliable partner, not just an installer.
