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.
3 Stories That Stood Out
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
Michael had already come back to Semper Solaris before, but this second project showed him something that really set the company apart: the after-install support. On a system that included a second house battery and solar panels, the last hurdle wasn’t the workmanship at all but the paperwork and permission-to-operate process with SDG&E. Daisy stepped in, made sure every required form got filed, and then kept him in the loop with Friday calls for more than five months until the approval finally came through. That kind of follow-through turned a frustrating utility delay into a finished job he could finally close out. Along the way, Semper Solaris had also replaced his roof, and he came away just as impressed with that work as he was with the persistence and care that carried the solar project across the finish line.
Clay had already trusted Semper Solaris with solar panels and battery storage a few years earlier, so when his 24-year-old heating and A/C systems finally needed replacing, he went straight back to Rhami Hasenin. That second project ended up being a full heat pump-based upgrade, and Rhami handled it with the same steady follow-through as the original installation. What really set the experience apart was how the relationship kept going after the big job was done: Rhami helped him line up annual filter changes, and during a San Diego heat wave he even helped connect him with maintenance after a Google thermostat warning popped up. For Clay, the value was having one dependable point person who stayed useful for both major installs and the small troubleshooting headaches that come later.
Gabriel’s experience with Semper Solaris turned into a drawn-out headache after the sale of a solar-and-battery setup on his home. A Marine Corps veteran who had been with the company since 2020, he came back years later to discover the Solaredge monitoring app had gone blank, only to learn that the monitoring stops after five years unless he pays Solaredge $44.99 for another year or waits weeks for a Semper Solaris modem install that would cost $300. He had expected the monitoring to be part of the system from the start, and the lack of warning left him feeling misled, especially after the company’s veteran-focused advertising had promised something very different. After three weeks, tech support got the system back online, but then the app began showing his battery as missing altogether, even though he had one installed specifically to keep medical equipment powered during outages. By the time he checked again, none of the panels were showing production either, and he was told he would have to wait 5 to 7 days just to get a call scheduled, with another 5 to 7 days possible before a technician could even look at it. What stayed with him most was the sense that the company moved as
A few years ago, Neal and his household compared three solar outfits for a new rooftop system: SunRun, Tesla, and Semper Solaris. What set Semper Solaris apart was the combination of thoughtful design, a smooth installation, and the kind of customer support that came through later when something inevitably needed attention. He ended up with a system installed by a team that handled both the upfront planning and the follow-up service without leaving them stranded when issues popped up.
John’s solar system has been running for years now, and the experience stayed strong long after the first install. From the original setup to the customer service and ongoing system support, Semper Solaris kept things smooth, with technicians who came across as helpful and professional each time they were involved. What stood out most was that the relationship did not fade after installation; the support held up years later, which is the kind of follow-through homeowners remember.
Gina’s latest run-in with Semper Solaris came five years after the solar and battery setup went on her home, when the Solaredge monitoring app on her phone suddenly went blank and stopped showing how the system was performing. She tried to get help through the company she thought had installed the system, only to land with an answering service that could do little more than collect her information and pass it along. Several days later, tech support finally reached her with the explanation that the monitoring app expires after five years. From there, the choices were stark: pay Solaredge $44.99 for another year of monitoring, or wait several weeks for Semper Solaris to send someone out and add a modem for $300. What frustrated her most was that she had already paid thousands for the installation and believed that essential piece should have been included from the beginning, especially after being drawn in by the company’s veteran-focused advertising as a 20-year Marine veteran herself. By the end, she was left with a system that came with hidden extra costs, a customer service line that couldn’t answer basic questions, and the feeling that the support she needed had arrived far too晚
Gerry has had solar on his home for years, and the part that stood out most was how the company kept showing up long after the panels were installed. Whenever he called, they helped him out directly instead of shuffling him around or passing the buck. That kind of steady follow-through turned a long-finished install into an ongoing service relationship, which is rare enough to notice.
Clay first turned to Semper Solaris for solar and battery storage, then came back when a 24-year-old HVAC system finally gave out. The real standout in his experience was Rhami, who stayed his main contact through both projects and delivered again with a new heat pump-based HVAC replacement. That same responsiveness carried over into the small stuff, too: when he needed an annual filter swap or a maintenance visit after a thermostat error, Rhami handled it quickly. By the end, Clay had more than a home running on newer equipment — he had one dependable person at Semper Solaris he knew he could reach whenever something needed attention.
Ronald had been satisfied with the original install six years earlier, but the experience soured once the equipment started failing. Over time, one Panasonic panel cracked, a Tesla battery went bad, and most recently the inverter quit working. Each time he needed help, he ran into the same wall: no direct line to support, just a customer service desk that took the message and passed it along, leaving him waiting several days for a callback. What started as a smooth installation ended up feeling like a slow-burn service problem, especially with three separate solar components failing within six years.
