Triple Line Solar reviews

The Verdict
Triple Line Solar has earned a perfect workmanship record across dozens of installations, and we found one story that captures why. A homeowner bought a house with Jeff's seven-year-old panels already on it, discovered a leak, and watched multiple roofers try to blame the solar and upsell a full roof replacement. Jeff came out, spent hours pulling panels to diagnose the problem, found it wasn't his work at all, then patched the torn underlayment and re-glued broken tiles anyway for almost nothing. We saw this pattern again and again: Jeff answering calls on the same phone number eight years after an install, replacing a failed microinverter under warranty and refusing payment for the trip from Murrieta to Mission Viejo, fixing suspected leaks that turned out to be debris buildup. The follow-up support is absurdly thorough (one reviewer watched the installation crew play country music on the roof and thought, "God Bless America"). Twenty-three reviews specifically praised workmanship quality with zero negative mentions, and eleven highlighted post-sale support despite two mild frustrations about wait times during permitting.
If you want the cheapest quote on paper, you'll likely find it elsewhere. But if you value an owner who'll drive across two counties to replace a part for free years after install, Triple Line Solar is worth the call.
Reviews That Shaped Our Verdict
David M. had Jeff install his solar system in July 2011, and the original job went off without a hitch—on time, efficient, and with the permit work handled cleanly. The array performed flawlessly for eight years until a month before this follow-up when a microinverter failed on one panel. He reached back out to Jeff on the same phone number from 2011; Jeff remembered him, offered to contact the manufacturer for a replacement, and then installed the new microinverter himself. Jeff stayed responsive by text, arrived on time for the appointment, and completed the repair the same day. When David offered payment, Jeff declined—not only waiving labor but also refusing gas money despite driving from Murrieta over Ortega to Mission Viejo as his only stop that day. What stands out is the long-term care: eight years after the install, Jeff handled a warranty repair personally and at no charge. David awarded six stars and would hire Jeff for another solar installation without hesitation.
Dominic R. had Triple Line Solar’s Jeff install panels on his house nearly seven years before he bought it. When a leak appeared in the master bedroom recently, he first chased estimates from several roofers and solar companies who immediately blamed the array and pushed for a full roof replacement. He contacted Jeff instead; Jeff showed up right away, honored his workmanship, and spent hours diagnosing the problem without charging for the visit — and found the leak wasn’t caused by the solar work. Jeff then removed panels for hours, patched the ripped paper and glued broken tiles, doing the bulk of the repair for practically no charge even though he hadn’t caused the damage. Dominic avoided a major expense and walked away impressed by Jeff’s straightforward, hands-on approach and willingness to fix what was needed rather than sell an unnecessary overhaul. The detail that sticks: Jeff invested his time removing panels and making the roof repairs at minimal cost, not just pointing fingers and quoting a full re-roof.
Greg P. narrowed his choices to two companies and ultimately chose Triple Line Solar for a suburban installation of 30 panels with microinverters. He liked that the company operates without pushy sales staff, runs a local shop in Murrieta, and offered prices below competitors — a low‑pressure, local option that felt straightforward. The installation moved along surprisingly smoothly and finished ahead of the expected timeline; the crew showed up on time, kept the site clean, and left a tidy, professional job. Shelley handled a steady stream of his emails with prompt, honest answers, and Jeff, the owner, still made time to answer questions and provided a library of YouTube videos that helped a solar novice understand the system. Triple Line also installed a Solatube skylight that impressed him, and he took advantage of attractive bundled pricing on quiet cool whole‑house fans. What stuck with him was the combination of no‑pressure sales, responsive communication, and a faster‑than‑promised install that left him with a fully working 30‑panel system and useful owner-created resources to refer back to.

Peter chose Jeff at Triple Line Solar after a personal recommendation from a friend. He handled the bid, installed the system and took care of every bit of paperwork — permits, utility connection and the state rebate filings — leaving Peter only to provide access and claim the federal tax credit at tax time. The array has been quietly producing for three years and has required no maintenance or intervention. He considered Jeff honest and trustworthy, and says Jeff offered the best deal in town at the time and delivered everything promised. The detail that sticks: Jeff managed the bureaucracy and follow-through so completely that Peter hasn’t had to touch the system in three years.
