#6 of 678 scored in California by Solar.com Installer Score

How does Northern Pacific Power Systems compare where you live? Rankings are local; an installer that leads one city can trail in the next. See how they rank in your city →

Why this differs from star ratings: most five-star reviews say “great company” and stop, and star averages reward that. These category scores only count reviews with concrete evidence, weighted by recency and the reviewer’s track record. A company can hold a strong star average while specific categories score lower; that gap is usually where the real story is. Categories with more complaints than praise are the questions worth asking any bidder, not necessarily dealbreakers.

Where Northern Pacific Power Systems builds

County-by-county activity from CPUC records through May 2026.

What this data covers: *Counts on this page, including the totals up top, come from investor-owned-utility interconnection records (SCE, SDG&E, PG&E). Work in municipal-utility territory, such as LADWP or city utilities, and outside California does not appear here, so this company's true totals are higher than shown. Unlike the county rankings, this profile also shows counties below the 250-install ranking floor.

Northern Pacific Power Systems reviews: what customers say

An independent synthesis of published customer feedback across Google and Yelp, updated September 23, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity8.0/10

Reviewers generally describe the sales process as clear and detail-oriented, with proposals that explain scope and expected outcomes well. A small number of complaints focus on concerns about follow-through, contract expectations, or sales leadership not addressing issues to the customer’s satisfaction.Solar.com's composite of published customer feedback, not a customer quote

Detailed proposal walk-throughs. Many reviewers say the proposal process was thorough, with the team explaining the design, scope, and math behind the system in a way that felt clear and credible. Representative review excerpt: "From first conversations with Sebastian, I could tell this company was reputable and he walked through every detail of the proposal and project."

Tailored system planning. Reviewers also describe designs that matched their needs closely, including planning around specific roof, battery, and scheduling considerations. Representative review excerpt: "Well, enter Tory who opens up his design proposal and had designed (without us asking) exactly what we wanted and had all the science and math to back it up!"

Isolated sales concerns. A few reviewers report concerns about how issues were handled after they were raised, and some say they wanted more detail upfront before signing. Representative review excerpt: "When we raised concerns, I believe the salesperson my partner dealt with wanted to make things right, but sales leadership stepped in, dismissed our concerns as unfounded, and offered nothing."

Price & financing transparency

Price Transparency7.1/10

Feedback on pricing and financing is mostly positive, with several reviewers saying costs felt fair and paperwork was handled well. Still, some complaints mention surprise charges, billing timing, or missed incentive timing, which keeps this category more mixed than the others.Solar.com's composite of published customer feedback, not a customer quote

Fair pricing and paperwork support. Positive reviews say the pricing felt fair and that the team helped manage permitting, rebate paperwork, and related administrative steps. Representative review excerpt: "The pricing was fair, the team was knowledgeable and kept me in the loop, the PM worked with me on the best location for the battery, and the installation process..."

Unexpected cost complaints. A smaller set of reviewers report surprise pricing changes or billing before a project milestone was reached, which created concerns about transparency. Representative review excerpt: "They tried to tack on a huge price after the the given pricing."

Incentive timing and rebates. Some reviewers mention rebate or incentive timing as part of their experience, including cases where a cutoff was missed or the timing affected the final purchase decision. Representative review excerpt: "We had wanted to qualify for the battery rebate, but missed the cutoff and the state pretty much closed it down anyway."

Communication & coordination

Communication9.2/10

Reviewers overwhelmingly describe strong communication, with responsive staff, consistent project ownership, and good coordination across sales, installation, and system handoff. A small number of complaints mention gaps in follow-up, timeline clarity, or administrative coordination.Solar.com's composite of published customer feedback, not a customer quote

Responsive project ownership. Many reviewers say they had a clear point of contact who stayed involved and answered questions throughout the project. Representative review excerpt: "Once I signed on for this large install two years ago, Dan Moran has been my project contact and remains so through today when I had a question about the..."

Smooth cross-team communication. Customers also describe the sales, install, and system teams as keeping them informed and following through on what was promised. Representative review excerpt: "Sales team, install technicians, and system management communicated well and followed thru with what they promised."

Post-install follow-up gaps. A small number of reviewers say they wanted more direction after installation or had trouble getting a clear timeline during earlier stages. Representative review excerpt: "There's no follow up or direction on guiding the customer after installation."

Timeline reliability

Timeline Reliability8.5/10

Reviewers usually describe the company as reliable on scheduling, permitting, and activation, with many projects moving forward smoothly. Some complaints mention delays tied to permitting, HOA approval, or the longer-than-expected path to go-live.Solar.com's composite of published customer feedback, not a customer quote

Handled end-to-end milestones. Reviewers say the company managed design, permits, installation, inspections, and utility activation without requiring much coordination from the homeowner. Representative review excerpt: "From the very first call, they handled everything: system design, permits, installation, PGE activation, inspections."

Fast and efficient completion. Several customers report that installation finished quickly and that the overall process felt smooth and well organized. Representative review excerpt: "​ They installed my solar panels and Tesla battery backup in just two days, and five years later, the system is still ​running flawlessly."

Delay-related complaints. A small number of reviewers describe added delays from permits, HOA approval, or a longer path to activation than they expected. Representative review excerpt: "I was required to get HOA approval (a 30-day added delay) before installation could begin, but despite repeated attempts to get a timeline of the design recommendation, I never received..."

Workmanship & site care

Workmanship9.3/10

Installation feedback is strongly positive, with reviewers praising the crew’s professionalism, planning, and the quality of the finished work. Complaints are rare, but one review raises a concern about installation height relative to the roof deck.Solar.com's composite of published customer feedback, not a customer quote

Professional, efficient crews. Reviewers frequently describe the installers as professional, punctual, and efficient during the on-site work. Representative review excerpt: "The whole team was fantastic, Cassius and Devin crushed the planning process and Jonathon, Jake, Alexander, Max, and Tia knocked the install out beautifully in 2 days."

Careful roof coordination. Some customers say the team handled panel removal and reinstallation well when roofing work had to be coordinated. Representative review excerpt: "James and Francisco, the on-site crew, did a fantastic job removing the solar panels for our roofer and reinstalling them."

Rare workmanship concern. One reviewer reports a concern about the installation height on the roof, suggesting a possible site-specific workmanship issue. Representative review excerpt: "My system was installed only 4 inches off the roof deck, which I believe is standard."

Long-term support & performance

Long-Term Support9.2/10

Post-install feedback is strongly positive, with reviewers reporting solid production, reliable system operation, and helpful support after the sale. There is very little complaint volume in this category, so the overall pattern remains favorable.Solar.com's composite of published customer feedback, not a customer quote

Reliable long-term operation. Reviewers report systems still running well after installation, including cases where performance has remained strong years later. Representative review excerpt: "​ They installed my solar panels and Tesla battery backup in just two days, and five years later, the system is still ​running flawlessly."

Helpful education and support. Customers also say the team was informative after the install and helped them understand how to get the most from the system. Representative review excerpt: "After the initial contact to Northern Pacific Power Systems, I was contacted by Sebastian Tejeda, who was very informative and helped me understand the benefits of working with them."

Measured production results. Some reviewers share production figures that they view as evidence the system has performed as expected over time. Representative review excerpt: "We have had the system for ~6 months and have produced ~10MWh, exported ~6MWh to the grid and only imported ~2MWh from the grid with 37% grid dependence (imported/consumed)."

Bottom line: Northern Pacific Power Systems earns a strong overall review profile, with especially positive feedback on communication, workmanship, and post-install support.

Important context: this chart shows investor-owned-utility records only. Companies that shift work toward municipal-utility territory (LADWP and city power departments) or other states will show declining bars here even while building steadily elsewhere, and 2025-26 records also lag real installation dates. Treat this as a partial window, not the company's full trajectory.

How we built this data

Methodology: Counts are residential PV interconnections in investor-owned-utility territory (PG&E, SCE, SDG&E) per CPUC Rule 21 public records through May 2026. Postal and name variants are merged. Municipal utility territory such as LADWP, Glendale, Pasadena, Burbank, Anaheim, and Riverside Public Utilities is not included in those CPUC counts. Counts show recorded installations, not quality ratings. Reported costs are self-reported on owned-system interconnections. No installer can pay for placement.

Who we are: Solar.com is a solar marketplace — we connect homeowners with installers and earn a fee when projects move forward. These rankings and scores are computed from public installation records and published customer reviews. No installer can pay for placement, and no installer — including those we work with — can pay to change a score.
