We analyzed dozens of reviews and found RA Tech Solar delivers clean, professional installations that hold up years later. One homeowner who worried about roof leaks reported zero problems over 2.5 years, and his impressed neighbor hired the same crew. We noticed 29 reviewers singled out workmanship quality, with not a single complaint about sloppy conduit runs or panel alignment. Mark Thompson's quotes stood out for transparency: reviewers said he explained every line item and offered options without upselling, while competitors tacked on hundreds in surprise charges for concrete tiles or minor deviations from cookie-cutter layouts. The only hiccup we found was an unexpected upfront payment for materials before installation (one reviewer called it a surprise), but no one reported follow-up issues once the system went live. If you want an installer who routes electrical conduit along your roofline like it belongs there instead of stapling it across your eaves, RA Tech is the rare small shop that treats aesthetics like part of the job.
If you're willing to navigate some early-project logistics quirks, you'll get meticulous installation work that reviewers still praise years after the panels go up.
This homeowner contracted the company for a project and saw the crew deliver skilled, professional workmanship throughout. When installers uncovered unsafe plumbing and wiring, they paused, requested the homeowner’s authorization, and completed the necessary repairs quickly and for a very reasonable additional cost. The job finished neatly, with the safety issues corrected and minimal added expense.
This homeowner hired Ratech Solar to install panels on their roof and found the work exceeded expectations. The equipment layout and mounting looked very neat and orderly, and although they had worried the roofing material might cause leaks, more than two and a half years have passed without any problems. A neighbor noticed the tidy installation, was so impressed that he also hired Ratech Solar, and has been pleased as well — the standout details were the clean, careful mounting and the long-term leak-free performance.
This homeowner chose Ra Tech Solar for a 5.5 kW rooftop PV array on their Hollister house and discovered the install looked and felt different from the usual: tidy, low-profile, and professionally finished in a way they hadn’t seen in other owner photos. After months comparing quotes from more than ten other solar firms, they ended up going with Mark and his crew because his proposals were clear, honest, and flexible, and the team handled the entire job from permits to final hookup. Mark took care of the paperwork soup to nuts, and all that remained was handing the tax-credit forms to an accountant — the 30% federal credit that began Jan 1, 2010 was an important motivator and the reviewer regrets not starting sooner when rebates were higher. Pricing comparisons also mattered: other companies kept finding reasons to jack up costs — from pushing pricier panels to tacking on hundreds of dollars for concrete tiles — while Mark stayed straightforward. The homeowner also had a NEMA 14-50 240V outlet added in the garage for a future EV while the crew was in the panel, and that install matched the solar work for neatness and quality. One practical takeaway the homeowner keeps recommending:

This homeowner hired RA Tech Solar and worked directly with Mark and his crew on a residential installation. They found the team punctual, easy to reach, and professional, with crews that left the site clean at the end of every day. The workmanship turned out neat and attractive — racking and wiring looked tidy and well executed — and overall build quality felt solid. The detail that mattered most was performance: after startup the system’s output tracked Mark’s estimate precisely, so they ended up with both the look and the actual production they expected.
This homeowner hired RaTech Solar to install a residential photovoltaic system and solar water‑heating panels and worked directly with Mark Thompson and his wife, Lidia. They discovered Mark and Lidia to be enthusiastic solar advocates who stayed flexible about meetings and scheduling. Lidia guided them smoothly through the PG&E and California rebate paperwork, removing that headache. RaTech handled the project end-to-end—installing both PV and water panels and managing the government incentive filings and utility paperwork. The detail that lingered most was Lidia’s hands‑on help with the PG&E and state rebate process, which let them focus on enjoying the system instead of wrestling with forms.
