Northern Pacific Power Systems reviews

The Verdict
Northern Pacific Power Systems turns out installations that don't look like installations. We analyzed hundreds of reviews and found an installer who treats hiding conduit like an art form, who declines work if the math doesn't favor the customer, and who still answers emails eight years after the sale. One homeowner called his city inspector to schedule a battery final and learned that the inspector considers Northern Pacific so reliable he'd let them sign off on their own work. Another had six microinverters fail four years post-install and watched the team strong-arm the manufacturer into a warranty replacement despite a disputed power-outage claim. The consistency is unusual: 154 reviews mention workmanship quality, and exactly two are negative. We noticed 86 mentions of post-sale support with only 4 complaints, most involving permitting delays rather than the company ghosting anyone. The trade-off is price. Multiple reviews note Northern Pacific wasn't the cheapest bid, sometimes by a wide margin, but they explain the premium with specifics like reverse-tilt panel arrays on north-facing roofs or in-attic wire runs so clean one reviewer called them "slick." If you're optimizing purely for the lowest quote, you'll find it elsewhere. But if you want an installer who'll show up same-day when a breaker fails mid-summer, or who'll turn down your deposit because your roof can't support a system worth installing, the extra cost buys you a team that acts like they'll be around to fix it in 2032.
If you want panels that look factory-installed rather than bolted on as an afterthought, and a team who'll still troubleshoot your inverter app years after cashing your check, Northern Pacific delivers. You'll pay more upfront, but the workmanship and long-term support justify the premium.
Reviews That Shaped Our Verdict
Bill Bowden installed a residential solar system in July 2017, and eight years later—in July 2025—he discovered the array started cutting on and off during the peak solar weeks. He left a message for Eric Theriot, who called back within 15 minutes and passed the issue to Grey Keiser; Grey arranged for a repair electrician to be on site within three hours. The crew diagnosed a bad breaker and replaced it, resolving the problem within four hours of Bill’s initial call. He appreciated the fast, professional response from the Northern Pacific Power Systems team and the fact they performed the repair at no charge nearly eight years after purchase. The detail that stuck with him: a same-day, no-cost fix long after installation that demonstrated real long-term support.
A year after Northern Pacific installed a full-home system—23 solar panels, a Powerwall battery, a Span smart panel and an EV charger—Jim P found everything working flawlessly and producing even more power than projected. He had shopped multiple bids, including Tesla and larger national firms, and chose Northern Pacific not for the lowest price but for the clearest value. After doing his homework, he discovered the team brought the latest technology and design thinking while others tried to push older panels and central inverters. The installer engineered a reverse-tilt array on a north-facing slope to fit more panels and boost their efficiency, suggested useful hardware upgrades, and stayed unusually responsive from sales through project lead and installers. The crew treated aesthetics and future needs as priorities: conduit was hidden rather than strewn across the roof, attic wiring was neat, and they even ran open conduit to the main panel—something that made adding a hot tub circuit this summer trivial. Even the stucco patching around the new panel blended so well he noticed it. One year in, the system’s reliability and stronger-than-expected output were the payoff, but what he
A few years back Mike C. explored rooftop solar for his ranch-style home, which already had a patchwork roof and extensive pool-heating panels. He reached out to NPPS and spoke with Graham, who dug into the property details and even checked PG&E data. Graham concluded there wasn’t enough usable roof area to build a system that would truly benefit the household and walked away rather than push an underperforming sale — a moment that immediately impressed Mike. A couple of years later Mike circled back when he decided the timing was right. Designer Sebastian sketched a practical plan that involved removing much of the pool solar to free up space for electric panels. Sebastian stayed involved throughout design and permitting while Alex took over as project manager and shepherded the install process, answering every question along the way. On install day a crew led by Juan 1, with Juan 2 and Junior, arrived and set to work. Mike noticed how focused they were on avoiding ugly, runny conduit routes; instead of letting piping snake across the roof and down the siding, the team routed everything cleanly and deliberately. That attention to aesthetics and workmanship became a hallmark of

Mike L had Northern Pacific Power install a large rooftop solar array about 18 months ago. Throughout the sales meetings, the permitting paperwork, and the physical installation the team operated professionally and efficiently, which made a sizeable project feel straightforward. He now enjoys clean, free electricity from the system, and what stuck with him most was how painless the permitting and installation turned out to be.
Tom kicked off a home solar project with an informative conversation with Graham that set clear expectations. He watched installers Dan and Scotty work efficiently together and leave the roof and yard cleared of debris. Devin handled approvals and walked him through the permit and technical details so the paperwork moved smoothly. The team delivered attentive service through the sales and install phases, and he ended up pleased with the on-site work. About a year after installation he discovered the company offered little post-install transparency — no proactive follow-up or guidance on next steps. The standout: a strong, communicative crew during installation, but buyers should be prepared to manage post-install questions themselves.
