In recent years, the number of utilities across the country offering incentives to encourage customers to adopt solar power has grown substantially. Often this is because utilities are required to meet solar energy mandates or generation targets. Utilities have voluntarily encouraged the adoption of solar energy or established incentive programs to meet internal clean energy goals. While solar photovoltaic (PV) system costs are rapidly falling, costs for distributed systems are still above retail rates in most jurisdictions, and require incentives to support customer adoption. This book explores best practices for designing and implementing incentives for small and mid-sized residential and commercial distributed solar energy projects.
