How It Works

Solar payback period is the number of years until your cumulative energy savings equal your net system cost after incentives. The average US solar payback is 7-12 years. Rising utility rates accelerate payback because your savings grow each year while your solar cost is fixed. The federal 30% ITC significantly reduces upfront cost.
