"Got new hot water heater, but they said they were unable to assess the solar panel or install a new solar system.Strange, since they advertise solar hot water systems. I now do not have solar powered hot water heater, but have a regular electric one."

"Jeff was great to work with. He took the extra time to discuss questions we had while making sure our solar project was managed seamlessly from start to finish. Everything was planned for and taken care of, down to the small details where his crew took the time to color match the new electrical conduit on the roof as well as on the exterior wall of the house. The entire process was completed in a timely matter, from the initial planning stages, through permits, installation and inspections."

"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."

"Joel came out to our home in Grass Valley personally to meet with my husband and I to discuss our solar options. He was patient with our many questions and willing to explain exactly what he had to offer. He realized as we chatted that we could qualify, not only for the normal government rebates, but an extra one due to medical necessity, as we store medications in our refrigerator for our son. We just signed and are excited to work with Joel and his team and our project. It is going to be awesome to save money each year on our power bills!"
