Utility rules and programs for Hagerstown
Hagerstown Light Department and Potomac Edison serve Washington County, so which rules apply depends on your address.
| Utility | Type | Solar export rule |
|---|---|---|
| Hagerstown Light Department | city-owned | Hagerstown’s tariff rider lets extra kWh carry for the 12 months ending in April, after which leftovers are converted to dollars at the average fuel and purchase-power rate and credited to your account. The city says it does not mail a check for excess generation. |
| The Potomac Edison Company | investor-owned | Potomac Edison offers net metering under its Maryland rider for systems up to 2,000 kW; its page does not explain the credit math, so ask for the tariff. Applications are online only (since June 23, 2025) and carry fees since Nov. 6, 2025: none for Level 1, $50 plus $1 per kW for Level 2. |
Program details are from each utility’s own pages (read October 2026). See the Maryland incentives table for statewide credits and a status for every program.

Solar Panel Installation in Hagerstown FAQs
Is solar worth it in Hagerstown?
The sun is strong (about 1,160 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 Maryland 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. Maryland has no state solar income tax credit that we found; the state’s help is a sales and property tax exemption, the income-based Solar Access rebate (up to $7,500) and certified solar credits.
Do I need a permit for solar panels in Hagerstown?
Usually yes, and the utility may need to approve solar and batteries. City of Hagerstown Permits Office handles permits in Hagerstown; see the permit information above.
