Get answers to common questions about home solar services in Wilmington, Delaware.
For a typical 6-8 kW system in Wilmington, the gross cost before incentives ranges from $18,000 to $28,000. Crucially, Delaware homeowners benefit from the state's Green Energy Program rebate, which offers $0.35 per watt (e.g., $2,100 for a 6 kW system), and the 30% federal tax credit. Combined, these can reduce your net cost by 40-50%. Additionally, Delaware has no sales tax on solar installations, providing further savings.
Wilmington's four-season climate is very suitable for solar. While summer offers the most peak sun hours, panels operate efficiently in cooler temperatures and still generate significant power on cloudy days. Snow in winter can temporarily reduce output, but panels are installed at an angle to help snow slide off, and their dark surfaces accelerate melting. Annually, Wilmington receives ample sunlight to make solar a strong investment.
Installation requires a building permit from the City of Wilmington's Department of Licenses and Inspections. Your chosen installer will typically manage this process. Delaware's net metering rules, administered by Delmarva Power, are favorable, allowing you to receive full retail credit for excess energy sent to the grid. It's also important to check if your home is in a historic district, as additional design reviews may apply.
Prioritize local installers with extensive experience in Delaware, as they understand state-specific incentives and interconnection processes. Verify they are licensed, insured, and certified by the North American Board of Certified Energy Practitioners (NABCEP). Ask for references from recent installations in New Castle County and review their standing with the Delaware Division of Consumer Protection to ensure reliability.
No, a key benefit in Delaware is that a residential solar installation is exempt from property tax assessments, so it won't increase your property taxes. For net metering, your system will be connected to Delmarva Power's grid. You'll earn a credit on your bill for any surplus power you generate, which rolls over month-to-month, helping to offset your usage during less sunny periods like winter.
