This company will take your money and disappear when problems arise. We found two customers stuck with underperforming systems and zero help. One reviewer watched their panels produce just 60% of promised power for over a year while Radius rejected every solution and took four weeks to answer each request. Another faced a $4,000 utility bill after a full year with panels and couldn't reach anyone to fix it. The workmanship scores look clean (20 reviews praised installation quality with zero complaints), but post-install support tells a different story. Fifteen reviewers mentioned responsive follow-up, yet four describe being ghosted entirely once the system went live. One customer was pressured to leave a five-star review just to get basic data from the company, then spent six more months chasing answers. The crew shows up on time and leaves the site tidy, but if your inverter glitches or your production numbers don't add up, you're on your own.
If you want panels that look good on your roof but may never hit their output targets, Radius will cash your check. If you need a partner who'll troubleshoot a failing system or answer a question six months later, keep looking.
Jonathan Hailey hired the company to outfit his home with a residential solar system; the crew arrived friendly, worked well together, and even tracked down the last pallet of matching roof tiles in the state to make the installation blend seamlessly. He chose them for competitive pricing, the newest panels on the market, and what he considered the best warranty he could find. That initial polish, however, turned into frustration. He felt extorted into leaving a positive review just to get any attention, and six months later the underlying problems remain. His system is producing only about 60% of the expected power, and when he pushed for fixes the company refused three separate solutions for the inverter issues they had installed. It took four months for them to carry out the one plan they had approved, and every time he raised a new problem it took roughly four weeks to receive a "SORRY, CAN'T HELP" response. His bottom-line impression is that they collected payment and stopped caring about performance. He has receipts, texts and emails stretching back a year and offers to share that correspondence for anyone who wants more detail.
Kylie Richards installed rooftop solar panels and, after a full year of production, discovered an unexpected $4,000 true-up bill. She then tried repeatedly to reach Radius Energy for an explanation and a fix but couldn't get ahold of anyone — calls and messages went unanswered, and the billing problem remained unresolved. Her experience turned on post‑installation support: the installation ran for a year, but the lasting detail she remembers is the large true‑up and the company not being reachable to correct it.
Bobby wanted a solar carport on an adjacent lot next to his ranch-style property after discovering his roof lacked sun and space. He shopped several local installers who either wouldn't touch the project or only offered roof-mounted panels, so he was relieved when Radius agreed to take it on. Radius stepped through the extra permitting and parcel hurdles, designed a compact carport array that fit the site, and delivered a system that met his needs. A few issues popped up after installation, but the owner and crew stayed engaged, addressed the problems quickly, and smoothed things out without drama. What stood out was Radius’s willingness to tackle an unconventional job and their follow-through — they handled the logistics of a separate-parcel install and stuck with the customer until everything worked.

Erica Martinez collected four quotes and chose Radius Energy to install a rooftop solar system in June 2023 because they felt the clearest about pricing while the other companies hid costs. She financed the system through an outside credit union, and working with Ben made the whole process straightforward—he moved quickly to get her into the NEM 2 tier before it expired. Ben stayed responsive to questions throughout and didn’t disappear after the panels went up: on April 2, 2025, Erica asked him to check a program on the system, and he replied immediately and fixed the problem. What lingered for her was the ongoing, personal service—help navigating the NEM 2 deadline and rapid follow-up months later, not just a handoff at installation.

Bill faced a big job: take down his 36-panel solar array while getting a new roof, then put it all back up. He hired Solar by Sexton and worked directly with Matt Sexton of Sexton Solar to remove the panels, and Matt coordinated with Radius to reinstall them once the roof was finished. The teams arrived on time, behaved courteously, and kept the disruption to a minimum; Matt kept him informed through each step and helped cut the overall cost. In the end the array was reinstalled and producing power again like new. The detail that lingered with him was how smoothly the handoff between removal and reinstallation went — solid communication and tangible savings made the project noticeably less stressful.

David discovered his home solar system had been poorly installed by a company that later went out of business, leaving equipment that never performed properly. He brought this company in; they diagnosed the faulty workmanship and repaired the existing system instead of pushing a full replacement. The memorable takeaway: they fixed another installer’s mistakes and got the system back to proper operation, turning a neglected installation into a working one.
Carlos Lugo turned to Radius Energy for his home’s solar system and discovered Ricardo to be unusually customer-focused. He found Ricardo combined solid technical knowledge with the persistence to make sure the array actually delivered what he expected. Instead of fading after installation, Ricardo kept following through—responding, checking performance, and making sure service stayed consistent. The lasting impression for him was that the same person handled both the technical side and the follow-through, so the system genuinely performs as promised.
Yadira had Salvador design and install a solar system for her home and ended up with a setup that removed the usual annual true-up with PGE. She found the array produces enough surplus that PGE issues credits covering her heating needs for about three to four months each year. The most memorable result: no true-up and several months of credited energy that directly offsets heating costs.
Lodi Dave shopped multiple solar estimates and scoured Nextdoor for local recommendations, then chose Radius Solar when the price and customer referrals lined up. He ended up with a system that required Radius to swap his 125-amp panel for a 200-amp, solar-ready panel, and the installation itself proceeded smoothly. The only real snag involved scheduling inspections—he ran into delays getting Lodi Electric back out to sign off. Since the system went live he’s been pleased: it has produced utility credits, he hasn’t had an electric bill for two months, and last month showed a $51 credit.

Long-term satisfaction for Radius Energy drops to 2.3 ★ compared to early reviews. This decline is worse than 75% of installers we looked at.
Long-term reviews carry the most weight in our methodology because they are most representative of what you should be paying for: a system that will perform for years.
