I purchased my system in July 2017. Eight years later (July 2025), my system starting going on and off line during the peak solar generation weeks. I left a message for Eric Theriot who called back within 15 minutes and sent by concerns to Grey Keiser who sent a repair electrician out within three hours. The problem was a bad breaker which was fixed within four hours of my initial phone call. I feel the entire Northern Pacific Power Systems crew did an outstanding job and I appreciate their effort. There was no fee for this outstanding service, eight years after my purchase! I highly recommend a solar system from Northern Pacific Power Sytems.

A few years ago we wanted to install roof top solar. Our roof is very choppy and we had a lot of thermal (pool) solar. I looked at yelp and friend recommendations and I was encouraged to contact NPPS. I spoke to Graham and explained our pool solar and roof situation. Also gave him our PG&E billing info. He googled earthed our house. Graham told us based on our available roof space, he felt they could not install a beneficial system for us. NPPS would not do a system. Graham was great and professional. I was amazed a business would decline a job because it would not be beneficial for the customer. So fast forward to a couple years ago. We knew we needed to go with solar and I contacted NPPS. I worked with Sebastian the designer. We came up with a plan to remove a lot of pool solar to accommodate the electric solar. Sebastian was great to work with. Alex was our project manager and our solar was in motion. There wasn't a question I had that Alex didn't answer. He walked us through the process Come install day I met a great crew. Juan 1 was the lead with Juan 2 and Junior. What I learned very quickly is these guys are beyond detail oriented. There goal was never to have the electrical galvanized piping stretch across the roof and down the sides of the house. Well they didn't. I encourage anyone looking for a solar company to drive through their neighborhood. If you see a home with solar with ugly conduit running across the roof and sides of the house, you know NPPS did not do the job. So solar was installed great customer support. I learned a few months ago that with an approved medical device (PG&E medical baseline) there is a $27,200 rebate available for battery backup. Well we were in. I reached out to Sebastian who designed the system. NPPS handled all the PG&E rebate, permits ect. A few weeks ago the crew showed up for the install. I need to say we had a separate project that required a city inspector to sign off on a permit. I mentioned I'd see him in a couple weeks for our battery final. He told me "NPPS is a great company. As far as I'm concerned they could sign off on their own work. They are that good." So the crew arrived. Juan 2 was the lead with Colton and Bill was the electrician. The professionalism and attention to detail was outstanding. They took the time to explain to me the home owner the system as they were installing it. Alex was again our project manager. No surprise they did an incredible job. Alex came out after completion and walked us through our battery app. He and Bill before made sure to show us how to hook up our generator in a power outage when solar wasn't generating to charge our batteries to run the house. This is by far the longest Yelp review I've ever done. I felt it was important to share my experience with a great local company who absolutely cares about their customers. There are many choices out there. You are doing yourself a disservice if you don't give NPPS a call.

Northern Pacific Power Systems knows what it's doing. They just completed a solar system at our Cotati condominium and we could not be more pleased. Cassius in Sales gave us clear explanations of all our options to start with. Very knowledgeable. His experience and advice was appreciated. Then it was Addagio, who managed all the permits and requirements from the city, fire dept and PG&E. It was amazingly quick and seamless. Immediately following the required paperwork Ramundo, Tony and the rest of the install team were here and three days later the entire system was complete! Very tidy and clean work by the installation team. Last but not least was William, Northern's electrical expert who just today did the last of the wifi and connectivity so I can watch our investment on my iPad! Ain't technology grand!? Very efficient and professional team throughout at a fine price! Way to go Northern! We would overwhelmingly recommend Northern Pacific for any solar project!
