San Diego Solar gets the fundamentals right without any flash. We found a small, owner-operated outfit where the two brothers who answer your calls also wire your inverter and climb on your roof. One homeowner watched the county inspector congratulate Dirk on passing inspection on the first try, a rarity the inspector felt compelled to mention. Reviewers consistently note the no-pressure sales approach: when one couple asked about battery storage, Dirk recommended they wait because better products were coming soon, an answer that cost him an immediate upsell. The follow-up support is reliable across dozens of reviews, with customers reporting prompt replies years after install. Installation timelines run longer than you'd get from a crew-heavy company. One customer endured a six-week wait that turned contentious when scheduling conflicts and invoice confusion derailed a repair (the only negative review we saw), proof that a two-person leadership team can bottleneck when jobs stack up.
If you value an owner who'll personally run the conduit and explain why he chose each panel over a company that can field three crews tomorrow, San Diego Solar is worth the wait. Just confirm install dates in writing upfront.
Allen W. shopped around with five different solar contractors before deciding to go with the installer his neighbor had used. He ended up with an 8,000-watt system — 40 commercial-grade panels — that’s been live for ten months, and the meter now spins backward faster than it ever ran forward, even with the pool pump and A/C running. Dirk, the owner, handled every step personally: planning, permits, installation, rebates, and the electrical hookups himself. The county inspector remarked that passing on the first inspection is rare, congratulated Dirk, and cleared the system with no issues. When a storm knocked out power for a day in the mountains, they plugged into the garage inverters and ran the refrigerator and communications directly from the panels while the sun was up — no generator needed. Dirk also fixed a poor job by the original roofers and re-roofed the half of the house where the panels sit; that extra work cost roughly a third of what a separate roofing contractor would have charged, and because it counted toward the solar project they could take a bigger tax break. Two friends have since hired Dirk and are equally pleased, and Allen found the big national firms much pr
Skip had a solar emergency at his compact 704-square-foot home with ten panels when his original installer, Petersen Dean, went bankrupt and the buyer refused to honor the warranty. On 4/30/21 San Diego Solar arrived: four technicians showed up, the owner Brad chatted with him, one tech found and made a temporary fix in minutes, and the crew departed after about 40 minutes. They traced the failure to shoddy junction boxes and wrong wire connectors left by the previous company, and Brad promised they would return within two weeks to replace the boxes. Skip warned he was moving on June 7 and asked for the work completed before then; Brad replied “NO PROBLEM,” and Skip even offered to pay that day but accepted Brad’s offer to settle when the job was finished. He sent the crew off with a few cactus cuttings they had admired — a friendly start that set expectations for timely follow-up. What followed was a string of missed appointments and mixed messages. San Diego Solar texted and rescheduled repeatedly (notable entries: a promised 5/5 visit that never happened, a 5/14 message that they were “super busy,” and a 5/27 reply that they were finishing a 150-panel job). Calls and voicema—s
Annette chose San Diego Solar last September after interviewing several well-known companies and liked that the process felt low-pressure from the start. Dirk came out, walked her through the panel types and why they used them, and laid out the pros and cons of current battery options without pushing a sale — he actually recommended waiting for new battery products rather than upselling. The business is a small, local operation run by two brothers with years of experience, and the installation itself was efficient. On one visit when either Burt or Dirk was on site, she mentioned a patio leak; one of them climbed onto the roof, decided it was an easy fix, and repaired it on the spot — a detail that underscored their service. She also gets prompt replies to calls and emails. What lingered most was the combination of straightforward, no-hard-sell advice and the on-the-spot roof repair that made the experience feel more like hiring a trusted local contractor than dealing with a big company.

Excellent BBB standing. Strong complaint resolution.
After waiting a couple of years to see how things held up, Jerry discovered that his solar system continued to perform well and the company's aftercare stayed reliable. He hasn't needed much maintenance, but when follow-up was necessary Brad and Dirk stepped in quickly—capable, responsive and consistently courteous. He recommended San Diego-Solar to several friends, and they echoed his positive view. The lasting impression was clear: not just a smooth installation, but dependable service years later when it mattered most.
L C. hired San Diego Solar to put panels on their home and ended up appreciating how smoothly the whole project ran. Dirk answered a barrage of questions quickly and stepped in to navigate the red tape SDGE threw up, which took a lot of stress off their plate. His brother Brad and the installation crew worked fast, stayed friendly, and left the homeowner with a system they felt was well priced and easy to monitor — L C. enjoys checking real-time electricity use and timing. At no point did they feel pressured or shortchanged; the process felt straightforward from the first meeting through final hookup. The moment that stuck with L C. most came outside the work itself: while Dirk was meeting an inspector he noticed L C. struggling to get a rescued cat into a carrier, offered to help unprompted, and had the cat secured in about five minutes after an hour and a half of unsuccessful attempts. That combination of competent project management and unexpectedly neighborly help is what made the experience memorable.

Kalman hired Dirk and his team for a solar installation and found they handled the job with clear expertise and professionalism. He appreciated their command of the work and plans to hire them again for future solar projects.
Niel turned to a small, brother-run solar company after a friend recommended them for a home installation. He found the crew efficient and helpful; beyond completing the installation they tracked down and resolved a couple of issues with his breaker box so the system could run properly. He walked away impressed enough to recommend them to others.
Gaye M. hired Dirk and Brad Hosmer’s crew to install solar on her home and watched a tightly run team in action. She noticed they arrived early each day, stayed through the work, and left the property neat and tidy every evening. Dirk and Brad checked in with each other daily and coordinated the crew so problems got flagged and solved quickly, which left the system up and running and in prime condition. She found them easygoing, clear communicators, and professional throughout the process. What lingered for her was the team's day-to-day coordination — that steady teamwork translated into fewer surprises and a finished system that worked as intended.
Gail L. chose Dirk and Brad to install a 12-panel system—LG panels with Enphase microinverters—on her 1,200-square-foot home and ended up with a neat, high-tech setup. The owners moved quickly on a quote, patiently answered every question and gave her all the time she needed to decide, which kept the process low-stress. The feature that stood out most was the per-panel monitoring: the system lets you see each panel’s production, which she found amazing. Two installers completed the physical work in just two days, were courteous and efficient, and left the site clean. The array was designed so skillfully that no conduit is visible from the street, preserving the home’s curb appeal. Dirk and Brad handled all permits, and from start to live power the job wrapped up in about ten days. Their prices were competitive, but what lingered for her was how they treated her like family while delivering a tidy, high-performing system.
Bill had a Decra Shake metal-tile roof — a roof built to outlast him — and discovered that not many installers know how to mount solar on that profile. He was referred to Dirk at San Diego Solar by the roof manufacturer and found the crew trained and certified by Decra. The job took longer than expected, but the extra time paid off: the team executed the mounting carefully and he came away confident it won’t leak. He gathered about five quotes; most bids were competitive and within his budget, while one large, heavily advertised company quoted noticeably more. After roughly ten years of watching solar prices fall, he judged the current pricing reasonable for his situation, though your mileage may vary. As conversations with Dirk continued, his trust grew because Dirk demonstrated real expertise rather than trying to impress, which made him comfortable that the installers would deliver a system both sides could be proud of. He offered to answer questions and asked callers to have Dirk put them in touch with him in Bonita. The standout detail for prospective buyers: a Decra-certified crew handled a tricky metal-tile roof and delivered a watertight installation.
Waldo W. turned to Dirk and his team for another solar installation while remodeling his house. He chose them because the installer also being a licensed roofer made scheduling simpler and saved money—fewer subcontractors meant fewer delays and lower costs. Dirk and his brother Brad pulled the electrical, solar, skylights and roofing into a single, coordinated project, so everything fit together rather than being handed off between crews. He noticed the attention to detail, especially with Dirk up on the roof working alongside the crew, which made the quality focus unmistakable. The detail that stayed with him: one firm managing roof and solar cut complexity and kept the workmanship visible and accountable.
