Solar makes sense in Frederick because you buy expensive grid power from Potomac Edison, then get paid twice for your own: full retail net-metering credits plus tradable Maryland SRECs worth about $40 each. A typical 6 kW roof here produces roughly 8,100 kWh a year. As of August 2026, the 30% federal 25D homeowner credit has ended, so Maryland’s own programs carry the payback.
Frederick sits in one of Maryland’s fastest-growing corridors, and rooftop solar can pay a homeowner here in two ways at once. Your electric utility is Potomac Edison, the FirstEnergy company that delivers power across western and north-central Maryland, and it runs the interconnection that switches a home system on. Maryland gives you full retail net metering on that Potomac Edison bill, and your system separately earns Solar Renewable Energy Certificates you can sell for income. The local wrinkles are Frederick’s own: a large downtown historic district with its own review, and a ring of newer subdivisions with HOAs. This page covers what solar really costs in Frederick, how the credits and SRECs work, the historic-district and permitting steps, and how to tell if your roof is a fit. For the statewide picture, see our Maryland solar incentives guide.
Using NREL’s PVWatts model for Frederick (ZIP 21701), MySolarFY estimates that a standard 6 kW rooftop system produces about 8,100 kWh of electricity a year here. At Maryland’s one-SREC-per-megawatt-hour rate, that output is enough to earn roughly eight Maryland SRECs a year on top of the bill savings. Your actual figure depends on your roof’s pitch, orientation, and shade, so treat this as a starting estimate and confirm it with a site-specific model (NREL PVWatts, as of August 2026).
Why solar pays on a Frederick electric bill
Solar offsets the power you would otherwise buy from Potomac Edison, and that price has two moving parts. The supply portion, what Potomac Edison calls the Standard Offer Service Price to Compare, is 12.936 cents per kWh through September 30, 2026, then it steps down to 10.605 cents per kWh from October 1, 2026 through May 31, 2027 (FirstEnergy Maryland customer choice, as of 2026). On top of that you pay delivery: about 2.287 cents per kWh, a fixed $6.00 monthly customer charge, and a 1.376 cents per kWh EmPOWER surcharge (Maryland Office of People’s Counsel, as of January 2026). For context, Maryland’s statewide residential average has climbed to roughly 21.8 cents per kWh (EIA Electric Power Monthly, Table 5.6.A, 2026). The simplest way to see your own all-in number is to divide the total on your Potomac Edison bill by the kWh you used.
Your production is what turns that rate into savings, so estimate it before you commit. A rooftop system in Frederick makes far less in the short days of December than in June, and the yearly figure depends on your roof’s pitch, orientation, and shade. Rather than a generic number, estimate your own roof with NREL’s free PVWatts calculator, then have your installer confirm it with a site-specific model. That production drives both your net-metering credits and the number of SRECs you earn.

How Potomac Edison credits your Frederick solar
Net metering is the first of your two earnings, and Maryland keeps it at the full retail rate. When your panels make more power than your home is using, the surplus flows back to the grid and Potomac Edison credits it on your bill at the full retail rate, then rolls that credit forward to the next month (Maryland Office of People’s Counsel, as of June 2026). Your credits build through the long days of summer and draw down in winter. For a plain-English primer on how export credits work, see how net metering credits your solar exports.
The wrinkle comes once a year. At the annual true-up, any net credit you have not used is cashed out at the utility’s lower wholesale-style rate, well below the retail rate you pay (Maryland Office of People’s Counsel, as of June 2026). The practical lesson is the usual one: size the system close to your own yearly usage so most of your production offsets retail-priced power rather than being trued up cheaply. You also keep paying the fixed $6.00 monthly customer charge, so a solar bill in Frederick is rarely exactly zero.
| What you earn | How it is valued | Who receives it |
|---|---|---|
| Monthly net-metering credits | Full retail value, banked and rolled forward | The Potomac Edison account holder |
| Year-end surplus at true-up | The lower wholesale rate, below retail | The account holder |
| Maryland SRECs | A market price per 1,000 kWh produced | The system owner |
Note: Maryland’s net-metering rules are being revised in 2026, so confirm the current terms. Maryland sets a statewide cap on how much net-metered solar can enroll. That cap sits at 3 gigawatts in existing law, and the 2026 Utility RELIEF Act expands the program toward 6 gigawatts (SEIA, as of June 2026), while a separate 2026 law revises how net-metering capacity is counted. We do not assert a hard net-metering end date, because no current source confirms one. A system you interconnect now is credited under the rules in force when it is approved, but because the mechanics are in flux, ask your installer to model your specific payback against the current tariff.
Maryland SRECs: your second stream of solar income
This is the part that sets Maryland apart from a plain net-metering state. On top of the bill credits, your system earns one Solar Renewable Energy Certificate, or SREC, for every megawatt-hour it produces, and you can sell those certificates into Maryland’s market for cash (Flett Exchange Maryland SREC prices, as of June 2026). It is a separate income stream from the power savings, so a typical Frederick home earns several SRECs a year on top of a lower bill.
The price moves, so treat any SREC figure as a snapshot. In mid-2026 a standard Maryland SREC traded around $40 per certificate, but the market floats and the value is capped by the state’s Solar Alternative Compliance Payment, which steps down over time (DSIRE Maryland, as of June 2026). Because the trend is downward, model the SREC income in a 2026 quote conservatively rather than stretching today’s price out for fifteen years. Your installer or an SREC aggregator usually handles the registration and sales. SRECs go to whoever owns the system, which matters if you lease or sign a PPA.
Maryland incentives a Frederick homeowner can stack
Beyond net metering and SRECs, Maryland adds a grant and two tax breaks. One correction worth making up front: the old $1,000 state solar rebate has ended, so do not count on it. For the statewide picture, see our Maryland solar incentives hub and our guide to solar incentives, and for local pricing our Maryland solar cost guide.
| Incentive | What it gives you | The Maryland detail |
|---|---|---|
| Net metering | Full retail 1-for-1 credit, with an annual true-up at the lower wholesale rate (Maryland OPC) | Being expanded and revised in 2026, so confirm current terms |
| Maryland SRECs | One certificate per MWh, sold for income (around $40 in mid-2026) (Flett Exchange) | Price floats and the cap steps down over time, so model it conservatively |
| Maryland Solar Access Program | An income-eligible grant of $750 per kW, up to $7,500 (Maryland Energy Administration) | Replaced the old $1,000 rebate; first-come funding that can close mid-year, so confirm the window is open |
| Sales and use tax exemption | 100% exemption from Maryland’s 6% sales tax on solar equipment (Maryland Comptroller) | Applied at purchase; your installer normally handles it |
| Property tax exemption | The added home value from the system is exempt from property tax (DSIRE) | May require a filing with the state assessment office or Frederick County, so confirm it locally |
The state grant is income-eligible and can close mid-year, so read the fine print. Maryland replaced its flat $1,000 rebate with the Maryland Solar Access Program, which pays $750 per kilowatt up to $7,500 but is limited to income-eligible households and runs on first-come funding that has sold out before the fiscal year ended (Maryland Energy Administration, as of June 2026). Do not assume a state grant is in your numbers until you confirm you qualify and the application window is open. Maryland does not offer a separate state income tax credit for residential solar, so the value comes from net metering, the SRECs, the exemptions, and the grant if you qualify.
Going solar in Frederick’s historic district and growing subdivisions
Frederick’s local detail is a tale of two neighborhoods. Downtown Frederick holds one of Maryland’s largest local historic districts, so many homes near the clustered spires carry a Historic Preservation Overlay. The rest of the city and county is a fast-growing ring of newer single-family subdivisions, where the catch is usually the HOA rather than history. Both are workable, but they take a different first step.
Historic district: get preservation review before the building permit. If your home carries a City of Frederick Historic Preservation Overlay, the Historic Preservation Commission must approve exterior work before you pull a permit, using the Secretary of the Interior’s Standards (City of Frederick Historic Preservation Commission, as of 2026). In practice, panels that are not visible from the street, kept low and off a front-facing slope, generally meet those standards. Properties in a county historic district instead go through the Frederick County Historic Preservation Commission, which issues a Certificate of Approval. Build a few extra weeks into your timeline if your block is designated, and pick an installer who has done Frederick preservation reviews.
| Frederick site factor | What to plan for |
|---|---|
| Downtown home with a Historic Preservation Overlay | Historic Preservation Commission approval before the permit; keep panels low and off street-facing slopes |
| Newer subdivision with an HOA | Notify the HOA, but Maryland law limits an HOA’s power to ban a working solar system; confirm placement rules |
| City vs county address | City of Frederick homes permit through the city; unincorporated addresses permit through Frederick County |
| Potomac Edison interconnection | File before installation; you cannot switch on until Potomac Edison grants Permission to Operate (FirstEnergy) |
| Older or undersized service panel | May need an electrical service upgrade to carry solar plus a battery or EV charging |
Paying for solar in Frederick: cash, loan, lease, or PPA
There is no single right way to pay for solar; the best fit depends on whether you want to own the system and keep the SRECs and tax benefits yourself, or avoid an up-front cost. The table below compares the common paths. A lease or PPA can mean no up-front cost for eligible homeowners, but it is a long-term agreement with monthly payments, not free solar, and the system owner, not you, collects the SRECs and any state benefit. To weigh the long-run numbers, see whether solar panels are worth it.
| Path | Up-front cost | Who keeps the SRECs | Best when |
|---|---|---|---|
| Cash purchase | Full system cost | You, the owner | You want the fastest payback and the most lifetime savings |
| Solar loan | Little to none, financed | You, the owner | You want ownership without paying cash up front |
| Lease or PPA | $0-up-front where eligible | The third-party owner | You prefer no up-front cost and a simpler, fixed monthly bill |
What the federal tax-credit change means in Frederick
The federal homeowner credit is gone, but Maryland’s programs are not. The 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, so a Frederick homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS Residential Clean Energy Credit, as of 2026). For the full timeline, see what the end of the federal solar tax credit means in 2026. What carries the math now is Maryland’s own stack: full retail net metering, the SREC income, the tax exemptions, and the Solar Access grant if you qualify.
One federal exception remains, and it is not yours to claim. A separate commercial credit, Section 48E, is claimed by the business that owns a leased or PPA system, not by the homeowner. On a leased system you do not file for a federal credit yourself, because the company that owns the panels does. The 25D homeowner credit, by contrast, ended after December 31, 2025, so do not let a sales pitch tell a 2026 cash or loan buyer otherwise.
How to choose a solar installer in Frederick
Frederick has a healthy market of installers serving the Potomac Edison territory, from local Maryland companies to national brands. Rather than chasing a “best installer” list, screen any company against objective criteria:
- NABCEP certification, the industry’s professional standard for PV installers.
- A valid Maryland Home Improvement Commission license for the contractor.
- A clear workmanship and equipment warranty in writing.
- Real experience with Potomac Edison interconnection, Maryland SREC registration, and Frederick historic or HOA review if it applies to your home.
- A written production estimate and a transparent quote that models SREC income conservatively and shows your bill after solar. For a checklist, see the right questions to ask a solar installer.
For how the same credits work elsewhere in the state, compare solar in Baltimore and our Potomac Edison Maryland net-metering guide. MySolarFY matches you with licensed installers that serve your area so you can compare real local quotes side by side, with no obligation.

Frequently asked questions
Is solar worth it in Frederick, MD in 2026?
For most owner-occupied Frederick homes with decent sun, yes. You offset Potomac Edison power that starts around 12.9 cents per kWh for supply plus delivery, and Maryland pays you back two ways: full retail net metering and the SREC market, which recently traded near $40 per certificate (Flett Exchange, as of June 2026). MySolarFY’s PVWatts estimate for a 6 kW roof in ZIP 21701 is about 8,100 kWh a year (August 2026). Savings depend on your roof, usage, and how you pay, but the mix of a rising rate, net metering, and SREC income makes Frederick a solid solar market.
Who is my electric utility for solar in Frederick?
Potomac Edison, a FirstEnergy company, is the electric distribution utility for Frederick and most of Frederick County, and it administers your net metering and interconnection (FirstEnergy Maryland, as of 2026). Maryland’s net-metering rules are set statewide by regulators, so the full retail monthly credit and the annual true-up apply to Potomac Edison customers across Frederick. You may shop electricity supply through a third-party supplier, but Potomac Edison still handles delivery and your net-metering credits either way.
Do I need historic approval for solar in downtown Frederick?
Only if your property carries a City of Frederick Historic Preservation Overlay, or sits in a county historic district. Where it applies, the Historic Preservation Commission must approve the exterior work before you can pull a building permit, judged against the Secretary of the Interior’s Standards (City of Frederick Historic Preservation Commission, as of 2026). In practice, panels kept low and not visible from the street generally meet those standards. County-district properties go through the Frederick County Historic Preservation Commission for a Certificate of Approval, so build a few extra weeks into your timeline if your home is designated.
What is a Maryland SREC worth in 2026?
A Solar Renewable Energy Certificate is created for every 1,000 kWh (one megawatt-hour) your system produces, and you sell it into Maryland’s compliance market. In 2026, Maryland SRECs have recently traded around $40 each, below the state’s Solar Alternative Compliance Payment ceiling, which steps down over time (DSIRE Maryland, as of June 2026). The value moves with the market and is not guaranteed, so ask your installer to model SREC income at a conservative current price rather than an old peak. A typical 6 kW Frederick roof earns roughly eight SRECs a year.
What happened to the federal solar tax credit?
The 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, so a Frederick homeowner who buys solar in 2026 with cash or a loan cannot claim it (IRS, as of 2026). A separate commercial credit, Section 48E, can apply to leased and PPA systems, but the business that owns the system claims it, not the homeowner. Maryland net metering, the SREC market, and the state tax exemptions were not affected, so the local payback case still holds.
How do I connect rooftop solar to Potomac Edison in Frederick?
You or your installer file an interconnection application through Potomac Edison’s online portal before installation, along with a Net Energy Metering Rider application (FirstEnergy Maryland interconnection, as of 2026). Potomac Edison reviews the package and issues conditional approval to build, then a licensed contractor installs the system and it passes a local electrical inspection. After you send proof of inspection, Potomac Edison does a final review, sets a bidirectional meter, and issues Permission to Operate. Your system only starts banking net-metering credits and earning SRECs once it is approved to run.
