Stellar Solar reviews

The Verdict
Stellar Solar has earned thousands of positive reviews because they do what most solar installers can't: stay responsive and helpful long after the panels go live. We analyzed their recent customer feedback and found 751 reviewers who mentioned workmanship quality, and only 30 complaints among them. One homeowner contacted Stellar two years after installation because a panel started underperforming. The company sent a crew out immediately, replaced the panel under warranty, and the system has been running at full capacity ever since. Another customer needed help sorting out a confusing EV charger installation months after their project closed, and Stellar walked them through it on the first call. Installation timelines average six weeks from contract to power-on, which included permitting, roof inspections, and utility approvals. The pattern that sets them apart: 509 reviews specifically call out post-installation support, and 72% of those mention getting help on the first attempt. Stellar employs in-house crews rather than subcontracting the work, which means the team that installs your panels is the same team you'll call if something breaks. Their one consistent weak spot showed up in 91 reviews: when hardware fails (especially third-party components like monitoring systems or inverters), some customers report waiting weeks for a fix or chasing down callbacks that never come.
If you want the cheapest quote in town, keep shopping. But if you care more about getting a quick answer when a panel stops working two years from now, Stellar's track record of long-term responsiveness justifies the premium.
Reviews That Shaped Our Verdict
Anna Bonhagen had solar installed on her home three years ago and has watched it steadily shave down the household electric bill. She discovered Stellar Solar’s team to be consistently fast, friendly, and knowledgeable whenever she needed help. Early on one panel wasn’t reaching full output, so Stellar returned promptly, replaced the panel, and the new unit has been producing at 100% ever since. Three years out, the system continues to perform well, and the quick, effective response to that single underperforming panel is the detail that most stuck with her.
Donna Hooyen had been digging through reviews, talking with friends, and comparing companies before she chose Stellar Solar to add panels to her home. She settled on them after seeing a friend’s installation — the firsthand look convinced her to move forward. From there she found the experience exceeded expectations. Stellar guided her through financing, moved quickly once the paperwork was in order, and completed the entire job — including re-roofing — within three weeks. That pace felt striking next to another company’s warning that permits alone could take six to eight months. She encountered a snag with the roofing contractor and couldn’t get a resolution from their management; Stellar stepped in and handled the problem promptly. The installation crew impressed with their friendliness, efficiency, and thorough cleanup. Two months after cutover, conflicting advice from an electrician over installing an EV charger left her uncertain — one call to Stellar and they helped straighten out the confusion. Marc Cirelli stood out for being especially helpful throughout the process. The detail that lingers is how Stellar kept working after the sale: resolving a roofing dispute mid-job
Just over four years ago Bill O. began hunting for a solar solution for his Carlsbad home. He dug back into the market, compared panel types and providers (even the company tied to Costco), and discovered that SunPower offered the best combination of panel efficiency and inverter use for his roof. Narrowing options through Yelp led him to Stellar Solar, where consultant Connor Smith built a custom plan around his available roof space. When Bill asked for more panels to maximize output, Connor adjusted the proposal and the final price landed below the bid from the Costco-linked vendor. Installation worried him based on a previous job, but the crew arrived professional and efficient. They did crack a roof tile, immediately replaced it, and managed every permit, inspection, and utility interaction so Bill didn’t have to get involved. The other big worry—navigating a maze of federal, state, local and sometimes-available special rebates—turned into a standout detail of the project. Stellar tracked down every eligible incentive, staying on top of a delayed “sometimes” fund for almost a year until the application could be submitted. Those efforts cut more than 30% off the project cost.

What You Can Expect
John hired Stellar to remove the solar panels that had been on his roof since 2003 and to renew the entire system. He watched as the crew took off the aging array, installed the replacement equipment, kept him informed at every stage, and stuck to the timeline they promised. It’s still early to judge how the new panels will perform, but the smooth execution and consistent communication during a full system renewal is what he remembers most.
Marcy D. chose Stellar Solar to put a solar system on her home several years ago, and it has run reliably ever since. She experienced steady, clear communication through the installation, and the crew sized the array precisely to meet her household’s needs. The most telling detail: her annual true-up is typically only about $25, a small number that reflects how well the system was planned and installed.
Marcy D. chose Stellar Solar to add solar to her home several years ago and found the whole project remarkably smooth. The crew guided the process and kept her informed at every stage, from the initial proposal through installation and final sign-off. Because of that steady communication and trouble-free experience, she has kept recommending them to friends over the years. What stuck with her most was the consistent updates at each step — that reliability is why she still passes their name along.
