Precis Solar reviews

Corey first had Precis put a 12-panel rooftop array on their home two and a half years ago, and when the household added two electric vehicles last year they called Precis back to tack on six more panels. They returned for two simple reasons: the company proved trustworthy and reliable. Throughout both jobs they discovered that what Precis promised about the system and the installation process matched reality—everything turned out to be accurate—and the crews delivered tidy, high-quality workmanship. Staff stayed professional and attentive, and when someone wasn’t immediately reachable calls were returned promptly. The detail that mattered most to them was consistency: clear, accurate information up front and follow-through on it, so expanding to an 18-panel setup felt like a straightforward, confidence-building upgrade rather than a gamble.

Kathleen B. bought a residential solar system from Precis in 2018, and six years later it’s still delivering more power than she expected. From the first contact she encountered friendly, knowledgeable people, the installation went off without a hitch, and the finished array looks striking on her roof. Precis over-delivered on performance, and each year the system generates enough credits that SDG&E ends up sending her money — a payoff she openly enjoys spending.

On November 22, 2019 Phillip agreed to have SunPower by Précis install what was presented as an 18,467 kWh system for $44,733.60. He had already paid off 40 panels on the garage through another company, and Précis planned to add 36 more panels for a total of 76. Tim Marquez handled the sale; because Phillip is a retired contractor he explicitly asked that the team measure the load from his pool and pond pumps so the system would actually offset his usage. Marquez walked the yard with him, looked at the pool equipment, and promised the installers were industry professionals — even suggesting Phillip could expect, at most, about a $200 monthly bill or possibly nothing at all. After the array went live, the reality diverged sharply: Southern California Edison statements started arriving in the $500–$900 range each month, on top of roughly $400 a month for the solar loan. Phillip spent a year pressing Précis for fixes. Technicians eventually concluded the home “was probably using too much power” and identified failing microinverters that needed replacement. Even after replacements, the microinverters didn’t register properly. Then Fran from SunPower by Précis emailed on January 11, 202

Ron L. had a residential solar system installed three years ago and would hand the company ten stars if he could. He discovered they stay involved long after the install — constantly monitoring system performance. When production dipped for a particular month, he received a text alert, and the company dispatched a technician the same day to diagnose and fix the problem. He walked away impressed by the ongoing monitoring and the rapid, practical response to an unexpected drop in output.

Thomas H. partnered with SunPower and worked directly with Kristin and the Precis team to install solar at his home. The crew completed the project on schedule, and a year after installation he found the system performing well. His family has seen substantial reductions in their monthly electric bills, and the equipment continues to look solid. The memorable takeaway: an on-time installation paired with real, sustained bill savings after a year made the switch to solar feel worthwhile.

Larry T. had Sunpower by Precis install his Sunpower system back in 2016. When his asphalt shingle roof needed replacement in 2022, he discovered the roof work would require the solar panels to be temporarily removed and reinstalled — and that he was required to use a Sunpower‑approved contractor. Because no other approved company would take the job, he ended up forced to use Sunpower by Precis, which charged roughly double the quotes he had gotten from non‑approved installers. The crew finished the panel reinstallation late on 10/31/22. The roofing contractor then inspected the job and discovered serious damage to the new roof that required about $1,500 in repairs; Sunpower by Precis initially refused to reimburse that cost. A month later, on 12/01/22, he checked system production and found November output at only about one‑third of what it should have been. A technician from Sunpower by Precis came on 12/05/22 and found 12 of the 18 panels wired with reversed polarity; the tech corrected the wiring, but the lost production through November and December cost roughly $1,000. That, plus the $1,500 roof repair, amounted to $2,500 — which Sunpower by Precis also refused to cover at.

Felix A. first met Tim Marquez a few years ago when he had a SunPower by Precis system put on his home. He ended up calling Tim back again and again—Tim helped his aunt, his uncle and two neighbors get panels too—and treated each install like helping a member of the family rather than making a sales pitch. He relied on Tim not only for the equipment and installation but for real follow-through: customer service that answers every call and jumps on paperwork. When a refinance came up, Tim filled out the loan forms immediately and smoothed the process. The thing that sticks is the combination of personal, non‑pushy service and the quick responsiveness—Felix walked away with a solid SunPower system and the reassurance that Tim will handle any follow‑up needs.

N had a solar system installed in 2012 after being promised a "bumper to bumper" 25‑year warranty. Seven years later, in 2019, two microinverters failed. When N called for service, the installer refused to replace the equipment and directed them to the manufacturer — a Chinese company that had gone out of business. The installer said its own protection only covered installation for 10 years, not the equipment itself. N ended up with two dead microinverters and no warranty help — a concrete reminder to confirm who actually backs equipment warranties and how long installation versus parts coverage really lasts.

Larry H. bought a rooftop solar array from Precis several years ago — every panel had its own inverter and individual monitoring, and the system came with a 25-year warranty. A few years in, several panels started failing and overall output dropped sharply, so he reached out to Precis for service. Receptionists were polite and promised to forward his call, but he never heard back; after repeatedly calling he finally connected with someone. Precis leaned on the monitoring company, which insisted there was no problem even though Larry’s monitoring data showed the decline. The company then revealed the panels they’d installed were from a manufacturer that had gone bankrupt and left the market, which created complications for replacement. When he pressed the VP for a solution, the VP located an acceptable replacement but demanded $550 for the swap — effectively turning the promised 25-year warranty into an out-of-pocket charge. Frustrated by unanswered calls, what he viewed as broken promises, and the unexpected fee, he considered legal action and left a one-star rating, characterizing that as generous. The detail likely to matter most to buyers: the long warranty relied on panels from
