"I had Soltari install my solar panels and I’m really happy with how everything turned out. I was a little nervous going into it since I didn’t know much about the process, but they made it super easy to understand and handled everything. The team was professional, respectful, and just really easy to work with. They showed up when they said they would and made sure everything was done right. Now that it’s all up and running, I’m honestly so glad I decided to go with them. I’d definitely recommend them to anyone looking into solar 😊"

"Unfortunately my husband s company is moving us to the midwest. Even though we had a signed contract with Rick and Teresa at Sunriver Solar, they we very understanding and basically told us not to worry about it and to enjoy our next adventure. They even asked if they could help us with any of the moving stuff!!! They are a delight to work with, they do everything, they kept us up to date on what was going on, and, even though we could not work with them, we would highly recommend them. You really cannot go wrong with Sunriver Solar."
