High Definition Solar reviews

The Verdict
High Definition Solar is a gamble you shouldn't take. We found hundreds of reviews that split sharply down the middle: long-term customers who installed systems a decade ago and had warranty repairs handled smoothly, and recent prospects who describe aggressive door-to-door sales reps, no-shows for scheduled appointments, and pricing that one reviewer calculated at triple what a neighbor paid for a comparable system. The company excels at workmanship once you're on the roster (152 reviewers mentioned solid installation quality, and we couldn't find complaints about roof penetrations or wiring failures), but getting there means navigating high-pressure tactics and inconsistent communication. One couple reported their appointment slot given away because the wife didn't answer a callback within two minutes while working in surgery. Another homeowner discovered moisture damage under panels that three roofers said should have been flagged before installation. If you value transparent pricing and respectful sales conduct, this isn't your installer.
If you already have their system installed, you'll likely get decent warranty service. But if you're comparing quotes, the door-to-door pitch and erratic appointment handling suggest you'll spend more energy managing the sales process than evaluating the actual product. Explore other options.
3 Stories That Stood Out
Marek P. shopped for a small rooftop system and ended up meeting two different sales reps on different days. He watched the first rep open with assurances about the company’s longevity, certifications and BBB record while skipping over the firm’s poor Yelp ratings, then pitch a system without even checking his actual energy use. That rep started with an average price of about $60,000 and whittled it down to roughly $37,800 for a 3.6 kW package — a number Marek found higher than a SolarCity quote for a much larger, 6.5 kW system. To sweeten the pitch the rep applied a promo code (PHP28, listed as $8,291 off) and a supposedly “initial visit” discount of $4,309 that was valid only that day, then layered a 30% tax rebate so the final presented price landed near $17,500 for that 3.6 kW system. He also pushed LG panels as premium, but Marek’s own research showed they were standard panels that can lose about 20% efficiency. Marek declined, and an office scheduler soon arranged a follow‑up with a “commercial” rep who promised a faster, better deal. That rep began at $32,000 and pared the price down to about $14,900 for what Marek recognized as the same system the prior rep had priced at $1
Brian F. tried to set up a home solar consultation and his wife booked an appointment for 1/14/2022; they were promised a day‑before confirmation, but nobody called. When they reached out, a company representative shifted the blame onto them for not confirming. They gave the company a second chance and rescheduled for 1/22/2022 at 1:00 p.m. On 1/20/2022 a staff member called to confirm and his wife — both of them work as RNs in surgery — missed the ring because she was in the middle of an operation. She stepped out, called back within two minutes, and found their slot had already been given away. He walked away furious, calling it “worst customer service ever,” and questioned how the company would treat paying customers or handle future service issues — especially given an advertised A+ BBB status. The concrete takeaway: the company lost him over a missed confirmation and a two‑minute return call while a surgical nurse tried to respond.
Candice H. hired the company for a rooftop solar install after a brief pre-inspection that, she says, focused only on sun exposure and trimming a nearby tree. Less than six months later, after she put the house on the market, a buyer’s inspection flagged that the roof needed replacement — and the worst damage sat directly beneath where the panels had been installed. Inspectors found moisture problems that could lead to fungus, and three independent roofers concluded the solar crew should have identified the roof’s poor condition before any panels went up. She ended up facing a stalled sale and a projected loss of at least $20,000 tied to repair and diminished buyer confidence. Candice believes the installation may have accelerated roof damage, and that the company’s original pre-inspection failed to prioritize the roof’s condition. She also disputes the salesperson’s claim that solar “appreciates” near the full investment cost, calling that expectation inaccurate. On the communication side, the interaction with the operations manager, Janae, left her frustrated: Janae responded late to time-sensitive emails, defended the company by pointing to a city sign-off (which Candice saw

What You Can Expect
John's rooftop solar array, installed by Hi Definition Solar three years earlier on a steep, high roof, flagged a problem this summer when a notification showed the largest panel wasn't producing. HDS sent Marshall from their office to climb the daunting roof, find the fault and promise a warranty repair. Marshall handled the inspection calmly and quickly identified the issue, then returned as promised and spent five hours working alone to replace the wiring to each panel, redo the junction box and rewire the run down to the Enphase box at ground level. His professional, friendly manner and obvious command of the system reassured him, and he appreciated that the company stood behind the installation. The detail that lingered: a single technician completing a thorough, five-hour warranty repair on a difficult roof — the kind of follow-through that convinced him HDS backed their work.
Monique Miller had High Definition Solar install panels on her home in 2012 and enjoyed years of trouble-free operation until recently, when a roof tile broke beneath one panel and water started leaking into her attic, closet and bathroom. She called the company and discovered they only handle full-roof jobs — they could remove and reinstall panels but did not perform roof repairs. Local roofers told her they wouldn’t begin work until the panels were removed, leaving her stuck coordinating two trades. She called back and connected with Jairo Aguilar, who asked for photos, did some quick inquiries, and then called with a referral: a roofer she could work with directly to get the repairs done. The memorable part of the experience was Jairo’s follow-through — he went beyond the original scope to find a practical solution so she didn’t have to chase multiple contractors.
Sofia Ramos signed up for a residential solar system that was sold to cover her current usage and leave room for future family needs, but she discovered the panels barely made a dent in her electricity bill. The install experience compounded the disappointment: crews arrived unannounced, let themselves into her backyard, and left her feeling unsafe as a woman living alone when a stranger wandered around the property. The array went offline for months, and SMUD showed up to identify the fault before the company’s promised 24-hour monitoring ever alerted her — the work had been done incorrectly by the installers. The company offered a small reimbursement for the downtime, but she found it inadequate compared with the time and stress spent chasing fixes. She tried to return the system and tried for years to resolve the issues, eventually giving up and concluding she’d been scammed; their "A+ diamond" claims felt like a joke. Her lasting image is clear: technicians entering her yard without notice and panels sitting offline for months, a caution to insist on verified monitoring and tight oversight of installation before signing anything.
Shanshan had her solar system installed about five years ago, and the installer had been reliable from the start. When the array recently stopped producing any power, she contacted High Definition Solar; they dispatched a technician the same day, diagnosed the problem on-site, and restored generation quickly. The standout detail was the prompt, same-day service—five years after installation she still received fast, effective support that got her system back online.
Mike Brum has relied on a Hi Definition solar system at his home for 12 years. He finds the panels continue to perform well, and Hi Definition has stayed responsive whenever he needed help. The detail that stands out is the long-term support — help has been available not just at installation but again and again over more than a decade.
Xiao Y had solar panels installed on their house in 2015 and discovered that about 10% of the panels stopped producing power immediately and stayed dead for eight years. Over the last ten months they spent countless hours chasing the company, effectively forced to micromanage the repair process because crews and office staff didn’t communicate with one another. Technicians returned several times but each visit felt like groundhog day: a different person showed up with no handoff, ran the same diagnostic steps, recommended the same replacement, and produced the same result—no fix. Contacting the company grew harder with each attempt, and after years the array still contains nonworking panels, leaving the unresolved failure and poor service coordination as the lasting impression.
Cindy has owned a rooftop solar system on her home since 2012 and continues to enjoy hands-on support from Joel, Nathen and Jaito. Her array regularly outperforms neighbors’ setups, and she remains impressed with the panels’ performance and the ongoing help from the staff. The detail that sticks: the same technicians keep providing reliable, personal service years after the install.
When Sandeep decided to go solar in 2020 to outfit his home, he found High Definition Solar receptive and competitively priced. The crew managed the entire process — upgrading panels, coordinating the city inspection and carrying the project through to finalizing the interconnection with PG&E — and the installation moved smoothly from start to finish. Because that first job went well, he returned in 2023 to expand the array and push for an even greener setup; High Definition Solar again handled permits and the technical work so the addition proceeded without hiccups. He ended up with a larger, functioning system and a clean PG&E hookup both times — the repeat business underscoring how much of the heavy lifting the company takes off the homeowner’s plate.
Xiao Yu had a 12-panel rooftop system installed in 2015 and discovered two panels stopped producing after only three months, effectively losing nine years’ worth of their share of solar generation. They endured a ten-month slog trying to get repairs: HD Solar insisted on a full-price transfer of ownership from the previous owner before they would move forward, then bounced the homeowner between support reps so often that no one ever picked up the thread. Each new technician ran the exact same troubleshooting steps despite being told those steps had already been tried, and HD Solar repeatedly swapped brand-new microinverters — three times in a row — because their support flow dictated it, even though the fault lay with the panels themselves. Xiao Yu spent hours acting as an unpaid coordinator, getting employees to talk to one another, with zero progress for months. Only after directly calling the CEO did the company become responsive, and the broken panels were replaced within about a month. The sharp takeaway: watch warranty and ownership-transfer requirements closely at purchase, monitor early production, and be prepared to escalate quickly — or risk losing years of generation.
