Key Benefits of Going Solar in Delaware

Delaware offers several advantages for solar adoption. The state’s net metering policy allows homeowners to earn credits for excess solar electricity sent to the grid. Delaware also exempts solar installations from property tax increases, a significant financial benefit compared to many neighboring states. Additionally, the federal Investment Tax Credit in 2026 still provides substantial rebates on solar installation costs. Combined with declining panel prices, 2026 is an excellent year for Delaware residents to invest in solar energy.

Understanding Delaware’s 2026 Solar Incentives

The federal ITC currently covers 30% of installation costs, though this percentage may change. Delaware offers property tax exemptions for solar equipment, and some utilities provide performance-based incentive programs. Our calculator automatically factors all available incentives into your estimate, showing your true out-of-pocket cost and realistic return on investment.
