Lamorinda Solar divides customers into two camps. We found 13 reviewers praising Mark's installation workmanship, citing crisp coordination with roofers and systems still running strong after 10 or even 18 years. One homeowner had a leak fixed within 48 hours of calling, another watched their pool jump from 75 to 90 degrees in under two weeks. But we also found 7 complaints about repair refusals and premature failures. One HOA reported Mark flat-out refusing service calls because he hadn't been out in a couple years, even though they were planning a full system replacement. Another customer's panels started leaking after just 7 years (Mark has since retired, leaving them scrambling for warranty coverage). A third paid $20 for six O-rings Mark sold them, then found a 50-pack online for under $9. The installation reviews shine, but the post-sale pattern is troubling.
If you want a meticulously installed pool solar system and plan to ride it for a decade without needing Mark, this could work. But if you expect warranty support or affordable repairs down the line, the refusal-to-service complaints suggest you may be on your own.
Nita hired Lamorinda Solar to install a solar array at her HOA pool about 10–15 years ago. When that system started needing repairs recently, the company refused to come back, explaining they won’t service installations they haven’t visited in a couple of years. She had been planning a complete replacement and probably would have chosen them again, but the refusal to perform follow-up repairs ended those plans. The takeaway: for long-term maintenance on decade-old installs, this company may not provide the ongoing service homeowners expect, so plan accordingly.
Tim had a rooftop solar array installed by Mark, who has since retired. Seven years in, he discovered the panels were leaking and ended up needing a warranty replacement. He’s now scrambling to arrange that replacement, and the labor alone is turning into a significant out‑of‑pocket expense. That’s especially frustrating because the equipment was advertised to last 10–15 years, yet failed far sooner — leaving him on the hook for costly installation work despite still being within the expected lifespan.
Knut O. found that Mark did a solid job installing the solar array on his home, but the relationship unraveled once service was needed. He discovered steep service charges — Mark wanted $20 for six O-rings — so Knut bought the installer-recommended minimum of 50 O-rings himself for $8.86 and offered to share the extras with anyone who needed them. He tracked down a different repair company that fixed a panel covered by warranty for a fraction of the hourly rate the original crew expected. He also learned the installer had recommended a company that no longer exists and had promised the system would last more than 20 years; instead, the eight-year-old system developed repeated leaks and significant water loss. Frustrated enough to want to give a rating below one star, he warns future buyers to watch for expensive service markup and to test warranty follow-through — and he keeps those inexpensive O-rings as a concrete reminder.

James D. picked Mark and his crew to install a pool-heating system at his home and has relied on them for over twenty years. He discovered they handled the original installation cleanly and then kept the system running with rare, prompt service calls. Each fall they perform a winter check in October/November so the heater starts without trouble in spring — a detail he highlights as the thing that sets them apart. He found their pricing fair, the installation work solid, and the warranty reliable, and he appreciated how quickly they respond when needed. He brushes off the lone one-star review as off-base and considers LaMroinda Solar the top choice in the area; the consistent, decades-long maintenance and that dependable fall winterization visit are what stuck with him.
Mark brought a crew in to replace an aging pool solar system right after the house got a new roof. He leaned on years of experience to choose high-quality components — durable panels and a variable-speed pump — and completed the installation on the date promised. The system performs well, but what lingered in the homeowner’s mind was his eye for finishing touches: rather than the old white PVC that had been crudely spray-painted and worn away, he used black PVC routed along the roof so the plumbing nearly disappears against the new black roof. That small aesthetic choice, paired with solid parts and on-time work, turned an equipment swap into a tidy, long-lasting upgrade.

Cheryl M. chose Lamorinda Solar to install a solar system for her backyard pool. Four years later she has found the system still running strong with no problems and remains very happy with the choice. The takeaway that sticks: a four‑year, trouble‑free run — the kind of reliability future buyers will notice.
John W. had Lamorinda install a residential solar system about ten years ago, and it ran without trouble for the decade that followed. When a leak showed up recently, he called Mark; Mark phoned back that same night and was at the house the next day. Within a couple of days the leak was diagnosed and repaired, leaving him relieved. The memorable part of the experience was the rapid response—same-night callback and next-day visit that fixed the problem in days.

Brittney F. bought a solar system for her house 18 years ago and discovered it still performs like new. Living in a home with a pool they use from April through October, she relied on Mark and his crew not only for the original install but for ongoing care — he returns each fall to shut the system down and again in spring to bring it back online so the panels don’t risk freezing. She found the service and product quality exceptional and was surprised to see negative reviews elsewhere; the combination of long-term reliability and the seasonal hands-on support is what kept her system trouble-free after nearly two decades.
Tim K. had Lamorinda Solar put panels on his home back in the mid‑1990s, and after decades of trouble‑free operation he brought them back when a recent roof replacement required the array to come down. The crew removed the panels, replaced the interior components, and reinstalled everything. The work unfolded professionally — the team coordinated directly with the roofing contractor so tasks started and finished on schedule — and they left the yard cleaner than when they arrived. The standout detail: systems installed in the mid‑90s that delivered “zero problems,” and a tidy, well‑timed retrofit that avoided the usual headache of juggling multiple contractors.
