Utility rules and programs for Dover
Eversource serves homes in Dover.
| Utility | Type | Solar export rule |
|---|---|---|
| Public Service Co of NH | investor-owned | Eversource credits exports under the state’s alternative net metering tariff: for systems up to 100 kW, a bill credit for default supply, transmission and 25 percent of distribution, with no credit for the system benefits or storm recovery charges (we read Liberty’s tariff text for the formula; confirm with Eversource). Its delivery tariff lists application fees from Jan. 1, 2025: $200 up to 25 kW and $500 up to 100 kW. Apply and wait for approval before switching on. |
Program details are from each utility’s own pages (read October 2026). See the New Hampshire incentives table for statewide credits and a status for every program.
Permits and approvals in Dover
- City of Dover Inspection Services: permit information · 603-516-6038
- Inspections and permits are handled through the city’s online permitting portal, or by calling Inspection Services. Permit review is listed at 10 to 14 business days when all attachments are uploaded.
- The utility must approve the connection before you switch on: Eversource net metering and application to connect · your own utility’s interconnection page.
- Check any contractor on the NH license verification before you sign.
- We found no New Hampshire law that protects solar from homeowner association rules (a 2022 bill, HB 1380, was killed in committee); state law does allow recorded solar skyspace easements, so read your covenants.
Fees and steps change; confirm with the office before you start. We have not verified timelines for Dover.

Choosing an installer

Solar Panel Installation in Dover FAQs
Is solar worth it in Dover?
The sun is strong (about 1,100 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 New Hampshire 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. New Hampshire has no state solar rebate (repealed in 2024) or income tax credit that we found, and no sales tax; towns can exempt the value solar adds to your home from property tax.
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 Inspection Services handles permits in Dover; see the permit information above.
