Mark Naylor Solar Specialists installed a workable system, but expect some communication bumps along the way. We found 16 reviewers who praised timely installations and knowledgeable crews who solved tricky roof placements. One homeowner had panels installed on the wrong section of the roof, called Mark on a weekend, and got the issue fixed. Another had their 15-year-old system serviced three times over the years with zero drama. The consistency stands out: 23 reviews specifically mention solid workmanship, and crews named Dave, Austin, and Bucky earned repeat shout-outs for friendly, competent repairs. The downside is responsiveness. Three customers reported days-long callback delays or no follow-up at all, even during emergencies. One reviewer with a busted water heater waited a week for a promised return call that never came. If you value a proven install track record and don't mind playing phone tag during busy seasons, this is a safe bet. If you need white-glove customer service or have a complex system, shop around.
If you want an installer with a 20-year repair history and crews who'll fix leaks years after the original job, the trade-off is patience during peak season. You may wait days for a callback, but the work itself holds up.
Jason J., a construction pro with more than a decade on job sites, approached this solar install the way he approaches any trade: expect demand-driven delays and insist on clear communication. He contacted Mark through the company website and, after a few days, heard back. Prepared with questions and a sense of what he wanted, he received a concise, reasonably priced quote a few days later and knew he needed to lock in an install before summer ramped up. A last-minute cancellation opened a slot, so the crew showed up quickly and completed the work. During the install he discovered some panels placed on a roof section he hadn’t wanted used and reached out to Mark to explain his concern. Mark answered on a weekend, walked through Jason’s follow-up questions, and arranged fixes until the layout matched expectations. In the end he ended up with a high-quality array, a competitive price, and the confidence that the system will outlast expectations — the standout detail being that the owner took the time, outside normal hours, to correct the issue rather than move on.
Q had to reroof their Clairemont home and needed the 11-panel solar pool heating array Mark Naylor installed years earlier taken down and put back afterward. Mark’s crew bent their schedule to match the roofer, arrived on time, carefully removed the panels and stored them in the side yard. When it was time to reinstall, they showed up punctual again, got the panels back on the roof and operational quickly. A few days of dramatic weather — Santa Ana winds followed by cold nights — produced a leak, but one phone call brought a prompt, solid repair. The system itself has run trouble-free for years and kept the pool warm enough to extend the swimming season. The detail that sticks with Q: the team not only handled removal and reinstallation without fuss, they answered a service call quickly when conditions caused a problem, and the 11-panel array continues to deliver steady, warm water.
Adam P. called on a Saturday and left messages over the weekend after his conventional water heater failed and the home’s solar water heater stopped working, leaving the household without hot water. As a green home broker, he already knew the unit was a Vaillant German system and flagged that detail repeatedly. A technician named Dave called back on Tuesday and they scheduled an appointment for the next day; Dave arrived, glanced at the system for about ten minutes without removing the front plate, then explained the Vaillant was “complicated” and he wanted to run it by a colleague, Mark. Dave promised a follow-up later in the week and agreed to call by the next day because they had no hot water, but nearly a week passed with no return call. Frustrated by the lack of expertise and by being left in an emergency, Adam watched his wife spend 10–15 hours troubleshooting—she fixed the problem the following day. The detail that sticks: after contacting a company that advertises solar hot-water expertise, the family ended up repairing their own Vaillant system because the crew never provided the promised follow-up or meaningful diagnostics.

Tony found Mark after a next‑door neighbor recommended him when he decided to install solar on his home with a pool. Three years later, he remains extremely satisfied. Mark’s team stayed engaged after the install, checking in and making sure the system was performing as promised. The result went beyond lower bills — the panels extended the months he could comfortably use the pool, a benefit he hadn’t expected. He still points to the proactive aftercare and the longer swimming season as the most memorable parts of the whole experience.
Lynn N. had new solar panels installed in June 2020 to heat her pool — a $3,200 investment — and recently discovered the system no longer works. Five days ago she called for service and a phone representative assured her a technician would call, but no one did. She rang back today and encountered a rep who didn’t even ask her name or look into the problem and only said the company was extremely busy. Knowing the company has been around about 20 years didn’t soften the blow; she feels ignored and left with $3,200 of nonworking equipment and no scheduled repair.
Kelly B. kept calling this company whenever her pool’s solar panels acted up, and over several years they handled multiple repairs and full replacements. She found a team that proved honest, dependable and trustworthy, turning up with quality workmanship and what she describes as impeccable service. After repeated visits and reliable fixes, she still relies on them to keep her pool panels running.
Barry H. hired Mark Naylor to replace an aging solar system that heats his pool. He found the upfront price fair and figured he couldn’t have done the job much cheaper—or nearly as well—on his own. About a week after the crew finished, an old pipe they had tied into developed a leak; the installers came back promptly and repaired it for a reasonable charge. The standout detail for him was the follow-up: they didn’t walk away when a preexisting issue surfaced, they returned and fixed it without overcharging, which left him confident he’d use them again.
Vincent D. had Mark and his team install a solar heating system for his pool. When the system began leaking, he expected the repair to be handled under the warranty; the crew fixed the leak, and only afterward he discovered the warranty excluded fittings, parts and labor. He was then presented with a bill that included a $128 service-call fee plus charges for parts — none of which had been disclosed or approved before the work started. Feeling blindsided, he questioned what options remained after being charged without prior consent and criticized the company for not being upfront about potential fees and warranty limits. The detail that lingers: the unexpected $128 service charge and parts bill arrived only after the repair was completed, without prior notification or authorization.
David S. first hired the company to install pool solar at his home in 2004, so when a leak showed up recently he called them back. They arrived promptly, quickly located the leak and repaired it without hassle. The repair came at a reasonable price, and he appreciated that the same company that did the original install could still service an older system effectively. The detail that sticks: fast, competent troubleshooting on a pool solar setup installed in 2004 for a fair cost.
Tami J. first had the company install a pool-heating system on her home 15 years ago, and when she added active solar to the roof three years back they relocated the equipment to tie everything together. Recently one of the panels sprung a leak; Bucky came out today, patched the leaks and put the system back in service. She kept coming back because the team has handled installation, relocation and repairs reliably over a decade and a half — the standout detail being the hands-on responsiveness of technicians like Bucky who show up and get the system running again.
