"We are so excited that NRG helped us to install Solar Panels on our house in San Francisco! Their entire team was wonderful from their first presentation providing us with all the information to the completion of the installation. Their installation staff was wonderful and completed the project without a hitch. Nicole Greenwood our customer service rep kept us informed of each step along the way and made everything easy. We had gotten estimates from two other companies and are glad we went with NRG. No worries and a wonderful experience. We will recommend NRG without reservation. Thanks to your whole team! Marge B."

"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."

"We have worked with Spartan on multiple projects whether it was for a custom home build, or having them take care of my customers roofing needs while we handled a different part of the project. I have no worries when I refer customers to Spartan and can always rely on them to get my projects done when needed at a good value and in a timely manner. I'll be using and recommending Spartan for years to come."
