Solar panels in Frederick, MD: cost, incentives, and quotes

Frederick sits in western Maryland in Potomac Edison\u2019s service territory, and its solar economics are unusually strong compared to most of the country. Three things drive it: Maryland still operates full 1:1 net metering across all four major utilities; the state has an active SREC market that pays homeowners roughly $900 per year on top of bill savings; and Maryland\u2019s sales tax and property tax exemptions stack on top. Even without the federal residential tax credit (which ended December 31, 2025), Frederick payback typically runs 7 to 10 years, which is faster than most US markets in 2026.

Why solar makes financial sense in Frederick

Maryland\u2019s residential electricity rates average around 15.6 cents per kilowatt-hour, modestly above the national average. Frederick gets a workable 4.5 to 5 peak sun hours per day, less than the desert Southwest but enough for solid solar production with proper system design. The combination of moderate rates plus strong state-level incentives produces meaningful economics even now that the federal credit is gone.

The SREC market is what makes Maryland solar genuinely strong. Most states either don\u2019t have an SREC market or have one with prices so low it barely affects the math. Maryland SRECs currently trade in the $60\u2013$80 range. A typical 7 kW Frederick system produces 8\u201311 SRECs per year, generating $480\u2013$880 in pure SREC income on top of whatever you save on your Potomac Edison bill. That income alone is roughly what a $20,000 system\u2019s electricity savings would be in many states.

How Maryland\u2019s SREC market works

Maryland\u2019s Renewable Portfolio Standard requires the state\u2019s electricity suppliers to source a growing percentage of their power from renewable sources, with a specific carve-out for solar. To meet the solar carve-out, utilities buy Solar Renewable Energy Credits, where one SREC represents one megawatt-hour (1,000 kWh) of solar electricity generated.

Homeowners with installed solar systems register with the state\u2019s SREC tracking system (the PJM-GATS registry). Each megawatt-hour the system produces generates an SREC, which the homeowner can sell to aggregators who in turn sell to utilities. Most homeowners use an SREC broker that handles the selling for a small fee, simplifying what would otherwise be a logistical mess.

The SREC price floats with supply and demand in the Maryland market. The Solar Alternative Compliance Payment (SACP) sets a ceiling on prices: utilities can pay the SACP instead of buying an SREC. The SACP was $55 in 2025, declining gradually to $22.50 by 2030 under current law, which puts a long-term ceiling on SREC values. SREC income is most reliable through 2027\u20132028; the declining SACP makes the back end of the SREC market less certain.

Practical impact: a Frederick homeowner installing solar in 2026 can reasonably expect $500\u2013$900 per year in SREC income for the first 5+ years of the system\u2019s life, with the income tapering as SACP ceilings decline. This income materially shortens payback versus states without SREC markets.

Net metering and Potomac Edison

Maryland law requires 1:1 retail-rate net metering across all four major utilities (BGE, Pepco, Delmarva Power, Potomac Edison). For a Frederick homeowner on Potomac Edison, excess electricity exported to the grid earns bill credits at the full retail rate, currently around 15.6 cents per kWh. Credits roll over month to month within the billing year. At the annual true-up, remaining unused credits settle at the avoided-cost rate, which is lower than retail. Most installers design Frederick systems to match annual usage closely to avoid losing value at the annual reset.

Potomac Edison\u2019s interconnection process moved to a fully online portal as of June 23, 2025; emailed and faxed applications are no longer accepted. The full timeline from signed contract to running system typically runs six to ten weeks, with the Potomac Edison interconnection review often the longest single step. A local installer handles the city/county permits and Potomac Edison interconnection paperwork as part of the project.

The 2026 federal credit reality

The 30% federal residential tax credit (Section 25D) ended December 31, 2025, under the One Big Beautiful Bill Act signed July 4, 2025. For customer-owned solar installed in Frederick in 2026 and beyond, the federal credit is no longer available. The commercial credit (Section 48E) continues to apply to third-party-owned residential systems (leases and PPAs) through 2027\u20132030 deadlines.

Maryland is one of the states where the federal change hurts less than elsewhere, because the state-level programs (SREC, net metering, sales tax exemption, property tax exemption) carry a meaningful share of the value on their own. A Frederick homeowner can still see 7-to-10-year payback in 2026 without the federal credit; many states without comparable state programs see payback push beyond 13 years.

Permitting in Frederick

Residential solar in Frederick requires building and electrical permits through either the City of Frederick or Frederick County (depending on whether the home is inside city limits or in unincorporated county). Both jurisdictions issue residential solar permits as a routine matter for standard rooftop systems. Permit review typically takes 1\u20133 weeks. After install, the local inspector verifies the work and Potomac Edison performs its own interconnection review before granting permission to operate.

Maryland\u2019s solar rights statute (Maryland Real Property Code Section 2-119) limits HOA restrictions: HOAs cannot impose restrictions that significantly raise the cost of solar installation. Many Frederick neighborhoods have HOAs, but most approve solar installations without major friction when the homeowner submits a formal application.

Getting quotes in Frederick

Start by estimating what a system would cost and produce on your specific roof. Our solar calculator uses satellite roof analysis to size a system and estimate output and savings for your Frederick address. Then compare quotes from pre-screened local installers familiar with Potomac Edison\u2019s online interconnection portal and Maryland\u2019s SREC registration process. Ask each installer how they handle SREC registration and selling; an installer who partners with a reputable SREC broker simplifies the process meaningfully.
