The cost of solar panels in Delaware typically ranges from $2.50 to $3.50 per watt before incentives.

After applying the 30% federal Investment Tax Credit, the net cost drops to approximately $10,500-$14,700. Actual costs vary based on your specific roof, chosen equipment, and installer. We recommend getting at least three quotes from local Delaware solar installers to find the best price.

The average solar payback period in Delaware depends on local electricity rates, available incentives, and sun exposure. Most Delaware homeowners see a payback period between 6 and 10 years. After the payback period, you essentially enjoy free electricity for the remaining 15-20+ years of your system's life. Higher local electricity rates and additional state incentives can shorten the payback period significantly. A qualified Delaware solar installer can calculate your specific payback period based on your energy usage and roof characteristics.

Delaware homeowners who install solar panels typically save between $20,000 and $50,000 over 25 years, depending on system size, electricity rates, and available incentives. These savings come from reduced or eliminated electricity bills, net metering credits, and any applicable SREC income. As electricity rates in Delaware continue to rise (historically averaging 2-3% annually), your savings grow each year. The combination of the 30% federal tax credit and any Delaware-specific incentives helps maximize your return on investment.

The right solar system size for your Delaware home depends on your electricity consumption, roof space, and budget.

Factors like Delaware's average peak sun hours, your roof orientation, and any shading will affect how many panels you need. A professional Delaware solar installer will use satellite imagery and your usage data to recommend the optimal system size.
