Utility rules and programs for Westminster
BGE and Potomac Edison serve Carroll County, so which rules apply depends on your address.
| Utility | Type | Solar export rule |
|---|---|---|
| Baltimore Gas & Electric Co | investor-owned | BGE follows state net metering: each month your exports offset your use, you still pay the customer charge, and leftover credit is either paid out each April at the generation part of your rate averaged over 12 months or banked indefinitely (a choice you can switch only after waiting 12 months, per BGE). Your installer applies on BGE’s online portal; BGE says systems of 20 kW AC or less may take up to 20 days, and you wait for permission to operate before switching on. |
| 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 Westminster FAQs
Is solar worth it in Westminster?
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 Westminster?
Usually yes, and the utility may need to approve solar and batteries. Carroll County Department of Public Works, Permits and Inspections handles permits in Westminster; see the permit information above.
