  • "Overall great experience with Northstar Solar from start to finish. They provide a quality product and install. The entire team is very responsive and knowledgeable. I decided to go with them because of a friend that used the same company. He had nothing, but good things to say and I can see why."

  • "We used NorthStar solar to install 12KW solar system with a 20KW battery to backup our entire home in February of 2021. The process was super easy, and Ryan walked us through the quote over VC to make sure that we understood all the options and tradeoffs. We set up an installation time frame, and a few weeks before the window, the dates were finalized. The installation took 3 days and we only lost the power for a few of hours when the switchover happened. Since then we have not been affected by any of the outages in our area planned or unplanned. They handled all the bureaucratic details including the permitting and all interactions with PG&E. The only issue we encountered was the Enphase controller panel was defective. This was discovered at installation time when testing running the house on batteries and there was a buzzing sound coming from the panel. NorthStar got on the the phone with Enphase and got a new panel shipped once it was diagnosed to be defective. I lied above, there was another brief power outage when the panel was replaced. Finally, their quote came in 10% lower than other local solar companies. As you can see, we have nothing but positive things to say."

  • "Very happy with the new roof and solar system that we had installed by these guys. They were helpful in explaining the different product and how everything works when getting a new roof and solar system. I explored other companies but felt most comfortable having NorthStar handle the roof and solar together. Plus the price made it an easy green light. Ryan was great at communicating, The crew was very clean and hilarious guys to talk with. We are excited to be hooked up on solar. Thanks NorthStar"
