"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!"
