Utility rules and programs for Dover
City of Dover electric department, Delaware Electric Cooperative and Delmarva Power serve Kent County, so which rules apply depends on your address.
| Utility | Type | Solar export rule |
|---|---|---|
| City of Dover | city-owned | The City of Dover credits exports at its current kWh rate, offsets the next month’s bill and resets yearly, per its solar page. Residential systems are limited to 25 kW and 110 percent of two years’ use, the bi-directional meter costs you up to $200, and you need a building permit before installing. Ask whether the new state carry-over rule applies. |
| Delaware Electric Cooperative | member-owned cooperative | Net metering follows the same state law. The cooperative’s solar page (read Oct. 3, 2026) showed map areas where members could no longer export solar power and others where only non-export systems are allowed; we could not confirm whether that changed after Senate Bill 239. Call the cooperative at 855-332-9090 before you buy. |
| Delmarva Power | investor-owned | Under state law, Delmarva credits extra solar power on your later bills at the per-kWh supply and delivery charges (not the fixed monthly charge or societal-benefits charges), and unused credit carries over between yearly periods. Residential systems can be up to 25 kW and no standby fee is allowed. You apply to Delmarva for interconnection before you install; we could not read its application pages. |
Program details are from each utility’s own pages (read October 2026). See the Delaware incentives table for statewide credits and a status for every program.
Permits and approvals in Dover
- City of Dover Planning and Inspections: permit information · (302) 736-7010
- Solar panel installations need a building permit, and the city requires third-party electrical approval from a Delaware state-approved electrical inspector. Solar customers also start with an interconnection application to the city’s electric department.
- The utility must approve the connection before you switch on: Delmarva Power solar and wind page (Delaware) · Delaware Electric Cooperative solar interconnections · City of Dover solar page · your own utility’s interconnection page.
- Check any contractor on the Delaware DELPROS license lookup (electricians) before you sign.
- We found no Delaware statute that protects your right to install solar against an HOA (the Delaware Uniform Common Interest Ownership Act, 25 Del. C. chapter 81, does not mention solar), so your deed restrictions and HOA rules apply; get written approval before you sign (not confirmed).
Fees and steps change; confirm with the office before you start. We have not verified timelines for Dover.

Solar Panel Installation in Dover FAQs
Is solar worth it in Dover?
The sun is strong (about 1,190 kWh a year per kW, our estimate), but export credits are low, so solar pays most when sized to what you use at home or paired with a battery. See the Delaware incentives for the state credit.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. Delaware has no state solar tax credit that we could confirm; the state’s help is a grant of up to $10,000 for Delmarva Power customers and loans through Energize Delaware.
Do I need a permit for solar panels in Dover?
Usually yes, and the utility may need to approve solar and batteries. City of Dover Planning and Inspections handles permits in Dover; see the permit information above.
