Solar Panels in Delaware may surprise some, since the state is small and doesn’t get as much attention as solar leaders like California. Yet Delaware offers strong policies and attractive incentives that make going solar worthwhile. Homeowners here benefit from moderate sunshine and some of the most generous renewable energy credits on the East Coast.
Cost of solar panels in Delaware
The average installation costs between $13,000 and $22,000 before incentives. Price per watt averages $2.6–2.9. A typical household consuming 700–1,000 kWh monthly would need a 5–7 kW system.
Incentives and programs
Delaware’s solar market is supported by state and utility programs:
- Federal Solar Tax Credit (30%).
- Green Energy Program grants, which reduce upfront system costs.
- Solar Renewable Energy Credits (SRECs) — homeowners earn credits for every megawatt-hour their system produces, which can be sold for cash.
