"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."

"Working with the ILUM Solar team was a true pleasure. We started our project on our own and quickly realized we needed some help. I contacted ILUM Solar and Robert Dean took over the planning, permitting and installation process. We have had our ground mount 60 panel solar system for 3 years with no problems. Highly recommend."
