I can't tell how much we've appreciated Mark and the entire Sun Valley team. They have been thorough with everything! From the sales process, to installation, to follow-up education and training; they've done it all and have done it well! We are in the SRP territory and are already saving over 100.00 per month with the Demand Manager. We would highly recommend Sun Valley and solar in general. Now is the time to get it installed and benefit from the rebates tax incentives and tools such as the Demand Manager to maximize your savings.
