They are an amazing company!
From the first meeting to permits and drawings, to installation and completion, every step was done perfectly! No delays, no "oops", just smooth high-quality work, done on time and cleanup was amazing too! Thanks to Graham, Devin, Caitlin, Ray and Alex! Great products, prices and super nice people.

SOLAR INSTALLATION
From start to finish, our solar project was seamless. From Eric Theriot (Solar Specialist) to Eric Hammond (Lead electrician) to Alex Stanley (Project Manager) to the installers. The professionalism and service were top notch. i would highly recommend Northern Pacific Power Systems to anyone. They are a local company with high standards. Just wanted to also say thank you for the great job. JOHN AND MARY HEINDL

Great Solar Company!
Northern Pacific Power Systems completed our solar system this past February. From start to finish, this company is a class act! We have a very challenging 2-story home with a 12/12 pitch metal roof. We’d contacted a couple other solar companies, but when they heard steep metal roof, they didn’t even come out to look. But Northern Pacific Power Systems was up for the task. They did a great job and we are thrilled with our system. Great crew, both on the job site and in the office. Their goal was to make sure we were happy and they succeeded! We highly recommend them for your solar installation!

Solar/battery installation by Northern Pacific
We highly recommend Northern Pacific Power Systems for solar panels and backup batteries. Sales process was more of a technical session than "sales-y". Excellent project management and communication. Efficient, knowledgeable, and friendly workers who did excellent work. Assistance with obtaining NEM 2.0 and SGIP rebate was a bonus. Using DocuSign for paperwork was much appreciated. Milestone billing was great and every invoice came with a total updated project statement. Installation was faster than we expected - 4 months total from first sales visit during a very busy time for solar companies.

Exceptional Service
We were pleased from the first contact to the most recent when we were called to see how it all was working. Everything was explained and questions answered so we were comfortable moving forward. We purchased solar panels plus batteries because we qualified for the SGIP rebate from PG&E plus the federal tax credit so they made a huge difference in the cost to us. Once installed, we had good explanations and help figuring it all out. Plus all the people with whom we dealt were delightful people!

Fabulous company to work with
I am totally thrilled with NPPS from the very beginning to the completion of the installation of both the panels and the wall battery. Cassius and all the installers have been professional and courteous, explaining the process all along the way. My PG&E bill is now absolutely amazingly insignificant since I have not had to pay for any electricity. I highly recommend Northern Pacific Power to anyone who wants to protect our environment and decrease their carbon emissions.

A+ Experience!
I chose Northern Pacific based on the reviews I read on various websites, and I am extremely pleased with my experience working with them. My key contact, Cassius, was very knowledgeable, helpful and responsive. The system he designed meets our energy use needs perfectly, and the entire planning and installation process was well coordinated and easy to understand. I would recommend this local company in a heartbeat. Thanks!

Straight up company
The company was professional and efficient. Design was done by satellite and zoom meetings during the pandemic, with a single onsite visit prior to the final design being submitted to the city for approval. System we purchased was a 3.4 kW output with a 10 panel array on a roof mount with a 47 degree pitch, and their bid was competitive with others (just over 15K). Many companies would not install on a roof with this slope. The install was done in 1 1/2 days with a 4 person crew, and the routing of the electrical lines was discreet and painted to match existing house colors where necessary. Overall experience with the project was excellent. Just be aware that once the building permit is approved the charges come quickly and you will need to have your banking in order.

Great Solar system Company
Great solar system installed for our irrigation pumps and accessory buildings. Cassius handled our initial inquiry with a virtual evaluation that was accurate and thorough. We had wanted to qualify for the battery rebate, but missed the cutoff and the state pretty much closed it down anyway. The installation occurred a couple months later and was seamless. Alex walked us through the system, all the inspections, and dealing with PGE. And at completion Cassius again walked us through how the system works and how we can monitor it. Professional and competent all the way through.

Professional company throughout
Friends recommended Northern Pacific Power to us and we couldn’t be happier with our rooftop solar installation. The bid process with Cassius, the design element run by Alex and the installation by Chad and Jorge—the entire process was simple and professional. The orinal design had six panels on our highest producing roof and thirteen on the larger but less efficient roof. The designers found room for one more panel on the best roof. Better yet, the installers were able to put nine panels on the southern facing roof with ten on the eastern roof. Our product just kept improving. Finally, each of the aforementioned company representatives were pleasant and professional throughout. I recommend Northern Pacific Power without reservation. Eric J.
