Solar Installers in Delaware

Solar panel costs in Delaware typically range from $2.50-$3.50 per watt. A standard 8kW residential system costs $20,000-$28,000. The 30% federal residential tax credit expired on December 31, 2025, so this is the full out-of-pocket cost. State and local incentives, net metering, and SRECs may help reduce your net cost.

NABCEP (North American Board of Certified Energy Practitioners) certification is the gold standard. At minimum, your installer should hold the required Delaware state contractor license, carry liability insurance and workers' compensation, and have manufacturer certifications for the equipment they install.

The 30% federal residential solar tax credit expired on December 31, 2025. Homeowners in Delaware can no longer claim this federal credit for new installations. State-level incentives may still be available, including state tax credits, rebates, property tax exemptions, sales tax exemptions, net metering, and SRECs. Commercial projects may still qualify for the federal ITC under transition rules. Check with your installer or visit the DSIRE database for current Delaware-specific incentives.
