Electricity rate as of 2026-05-01. Sun hours: NREL PVWatts, central Maryland fixed tilt annual average; consistent with Frederick County location. Cost per watt: EnergySage March 2026, Frederick County; average system 14.01 kW approximately $35,918 before incentives; $2.56 to $2.63/W range.

Your utility determines your savings
Most of Frederick County and City are served by Potomac Edison (FirstEnergy). Some areas on the county edges are served by BGE or Pepco depending on the specific address. All three utilities offer Maryland's full retail 1:1 net metering under state law. Verify your utility on your electric bill before signing a solar contract; the interconnection application, SREC registration, and rate calculations all depend on the correct utility.
LADWP is a municipal utility exempt from the CPUC's NEM 3.0 mandate. Customers retain full retail 1:1 net energy metering. Every kilowatt-hour your solar system exports to the grid is credited at the retail rate you pay, estimated at 22 to 37 cents per kWh depending on usage tier.
Export credit: approximately 22 to 37 cents/kWh
Full retail 1:1 NEM. Verify at ladwp.com. Rate as of June 2026.
SCE customers are on the NEM 3.0 Solar Billing Plan, which took effect for new interconnections after April 2023. Under NEM 3.0, solar exports earn only 5 to 8 cents per kWh -- roughly 75 to 80 percent less than the retail rate. Battery storage becomes significantly more valuable for SCE customers: stored solar used during peak TOU hours at 35 to 40 cents per kWh avoids the most expensive grid purchases.

Your address determines your utility. Look up your utility at ladwp.com or sce.com before reviewing any solar proposal. The net-metering difference affects your estimated annual savings by $1,000 to $1,500 on a typical 8 to 9 kW system.
Available programs
Federal residential solar credit (Section 25D): expired. The Section 25D residential investment tax credit expired December 31, 2025. The residential credit rate is 0%. State and local incentives below may still significantly reduce your net system cost. Commercial systems still qualify for Section 48E (30%).

Why Frederick homeowners are moving now
Frederick County is experiencing a specific 2026 tension: large-scale solar developers are actively leasing farmland in Frederick, Washington, and Carroll counties at $4,500 to $7,000 per acre, creating visible utility-scale solar farms across the agricultural landscape west of the city. This heightens public awareness of solar as an energy choice and creates a contrast story for rooftop residential solar - producing locally on your own roof versus farmland displacement. The Potomac Edison TOU rate launched April 20, 2026 creates a new value proposition for battery-plus-solar bundles, and Frederick homeowners who install in 2026 lock in grandfathered 1:1 net metering terms before the Maryland Utility RELIEF Act's July 1, 2027 program transition.

Illustrative example
Zero federal residential credit applied (Section 25D expired December 31, 2025). Figures are estimates based on market data as of 2026-06-29. Your numbers depend on your roof, your utility, and your bill.
A 14 kW system at $2.60/W grosses $36,400 before incentives. Zero federal residential credit applies (Section 25D expired December 31, 2025). Frederick's 13 to 14 cents/kWh Potomac Edison rate is the lowest in the Maryland cities researched, which extends payback somewhat compared to Columbia or Baltimore. However, the 14 kW average system (largest in the Maryland research) and SREC income of $560 to $1,050/year partially offset the lower rate. Installing in 2026 locks in grandfathered 1:1 net metering terms before Maryland's July 2027 policy transition. Verify your utility at your Frederick address before signing any solar contract.

For business owners and property managers
Frederick County's agricultural-to-commercial solar pipeline, Potomac Edison territory, and Maryland's 1.5x SREC multiplier through January 2028 create strong commercial and agricultural solar economics. The federal Section 48E commercial credit applies to projects starting construction by July 4, 2026. Agricultural solar on Frederick County farms can command lease rates of $4,500 to $7,000 per acre from utility-scale developers, while commercial rooftop remains the community-compatible alternative.
See commercial solar optionsCommercial solar projects must begin construction by July 4, 2026 to qualify for the 30 percent Section 48E federal tax credit. After that date, the system must be placed in service by December 31, 2027.
