How Much Do Solar Panels Cost in Maryland Right Now?
A competitively shopped residential system in Maryland runs $2.73 per watt installed before incentives. For the typical home, that points to a 7.78 kW system at $21,239 before incentives, sized to cover a year of normal usage.
The sizing comes from Maryland’s sun exposure and average household consumption. Maryland gets 5.01 peak sun hours a day, a solid Mid-Atlantic resource, so each kilowatt of panels produces 1,432 kilowatt-hours a year. A home using 929 kilowatt-hours a month needs a 7.78 kW system to cover its usage.

Maryland Solar Cost by System Size
System size drives the total more than any other choice. At an average cost of $2.73/W plus or minus 12%, here is what gross cost looks like across the common system sizes, before incentives.
System Size | Avg. Cost | Solar + 13.5 kWh Battery | Best Fit |
|---|---|---|---|
6 kW | $14,400 to $18,300 | $29,925 to $33,825 | Smaller home or partial offset |
8 kW | $19,200 to $24,500 | $34,725 to $40,025 | Average Maryland home |
10 kW | $24,000 to $30,600 | $39,525 to $46,125 | Larger or all-electric home |
12 kW | $28,800 to $36,700 | $44,325 to $52,225 | Large home with an EV and storage |
*Based on a $2.73 per watt competitive price; the battery column adds $15,525 for 13.5 kWh of storage at $1,150 per kWh installed. Real quotes vary by roof, equipment, and installer.
A 10 kW system, the size many higher-usage Maryland homes choose, runs $24,000 to $30,600 before incentives, with a typical quote falling inside that range. Add a 13.5 kWh battery and the same system runs $39,525 to $46,125, since installed storage costs $1,150 per kWh and adds $15,525 to the project.
The Federal Solar Tax Credit Ended for 2026 Purchases
The single biggest change to Maryland solar economics in years arrived with the One Big Beautiful Bill Act, which ended the 30% Residential Clean Energy Credit under Section 25D for systems installed after December 31, 2025. If you buy a system with cash or a loan in 2026, there is no federal credit to claim.
For the typical Maryland home, that means the gross price is also the net price. There is no 30% reduction waiting at tax time, so the gross price is what you pay.
One structure still reaches a federal credit. Leasing or signing a PPA is the only 2026 path to a federal benefit, because the company that owns the system can still claim the separate commercial clean-energy credit and may pass some of it through. That value goes to the financier rather than you, though some can come back through a lower monthly rate; the full lease-versus-buy mechanics are covered in our Maryland free-solar guide. The financing section below covers the trade-off.
What Factors Drive Solar Costs In Maryland?
Equipment is only part of the price. A few Maryland conditions change the final number, some up and some down.
Baltimore’s Rowhomes Roofs
Many Baltimore city rowhomes have flat or low-slope roofs that need ballasted or tilt-up racking instead of a standard pitched mount, which adds to the install. Homes with under-200-amp service may need an electrical panel upgrade of $1,200 to $2,500 before a system can connect, and that line rarely appears in a headline per-watt quote.
Coastal & Eastern Shore Wind
Coastal and Eastern Shore roofs face higher wind uplift, so they need a structural letter stamped by a professional engineer to verify the array will hold. That review is standard on the shore and shows up in the labor cost.
Permitting & Interconnection Fees
County permits run $250 to $650, and a BGE interconnection costs $100 to $150. The bigger friction is timing: a January 2026 review by the Sierra Club and CHESSA documented permit waits of ten days but weeks-long delays getting permission to operate from BGE and Pepco, which can leave a homeowner paying a loan and a full utility bill at the same time.
Two things pull the price down. House Bill 1532 caps residential solar permit fees at $500, and Maryland charges no sales tax on the equipment. Larger rural roofs and a cash purchase also keep the per-watt number low.
The Sales-Tax and Property-Tax Exemptions That Cut Your Cost
With the federal credit gone, two Maryland exemptions carry the affordability case for owner-occupants, and both apply on their own.
Under Maryland Tax-General Article §11-230, solar energy equipment is exempt from the state’s 6% sales tax. Your installer applies it at purchase, so you never see the charge. For the dollar impact on a typical system, see Maryland’s solar incentives in detail.
The second exemption covers value rather than equipment. Under Maryland Tax-Property Article §7-242, the home value your system adds is exempt from real property tax. You get the resale value without a higher tax bill, automatically, for the life of the system.
Do not count on an up-front rebate. The legacy $1,000 Residential Clean Energy Grant for solar ended in late 2024 and was not renewed. The income-targeted Maryland Solar Access Program is capped, income-limited, and closed for the current funding year, so the typical 2026 buyer gets no state check at purchase. These two automatic exemptions are the reliable savings; the grant programs are not.
Solar Payback in Maryland
The payback works because the rate is high. For a typical home in BGE territory, which covers half of Maryland, a 7.78 kW system producing 11,141 kilowatt-hours a year pays back in nine years on the volumetric rate solar offsets, ranging 8.9 years in Delmarva territory to 12.8 years in western Maryland on Potomac Edison’s lower rate. The statewide all-in average prints a shorter 8.6 years, but that average includes fixed charges solar cannot erase, so it overstates real savings. Over 25 years the net comes to $70,000 as rates climb and the system keeps producing.
One wrinkle holds even after the credits net out: the BGE and Pepco fixed monthly customer charge persists after net metering, so a bill rarely reaches zero even when production covers usage.
Payback alone understates the return. Three things decide it: your rate exposure, how long you stay, and how you finance. A homeowner staying 15 years on a rising rate sees a different result than one planning to move in three. For the full long-horizon picture, see whether solar is worth it in Maryland.
Net Metering and the HB 1532 Closing Window
Full-retail net metering is the load-bearing benefit. Under Maryland Public Utilities Article §7-306, the grid nets every exported kilowatt-hour against your usage at the retail rate, carries any surplus forward month to month as a kilowatt-hour credit, and cashes out leftover credit each April at the lower commodity rate. That one-to-one credit is what holds payback to nine years.
That window is closing to new systems. House Bill 1532, the Utility RELIEF Act, took effect on enactment as an emergency measure in 2026 and ends new-entry full-retail net metering at the earlier of a 3,000 MW statewide cap or July 1, 2027. The Public Service Commission must set a lower-paying successor by February 1, 2027.
Installed capacity counting toward the cap, rooftop net metering plus community solar, already sits at 51.23% of the 3,000 MW limit, with a 2,911 MW community-solar pipeline behind it, so the cap could fill well before HB 1532’s July 1, 2027 backstop. A system interconnected before the cutoff stays on full retail for its life. Our Maryland incentives and worth-it-solar guides cover the successor in full.
Solar Payback by Maryland Utility
Your utility changes the payback. The statewide all-in figure uses the 22.2¢ rate. Measured against each utility’s volumetric per-kilowatt-hour rate, the rate solar offsets, the picture shifts by service area.
Utility | Volumetric Rate | Year-1 Savings | Payback (Years) |
|---|---|---|---|
BGE (central Maryland) | 21.10¢/kWh | $2,351 | 9.0 years |
Pepco (DC suburbs) | 19.76¢/kWh | $2,201 | 9.6 years |
Delmarva (Eastern Shore) | 21.51¢/kWh | $2,396 | 8.9 years |
Potomac Edison (western Maryland) | 14.88¢/kWh | $1,658 | 12.8 years |
*Year-1 savings apply each utility’s volumetric rate to 11,141 kilowatt-hours of annual production; payback divides the $21,239 net cost by that saving. Volumetric rows run longer than the all-in headline figure.
Western Maryland is the clearest split. Potomac Edison’s 14.88¢ rate is the lowest in the state, so the same system there takes 12.8 years to pay back, while a BGE or Delmarva customer crosses nine years.
Paying for Solar in Maryland: Cash, Loan, Lease, or PPA?
The end of the federal credit reshuffled the financing question. Each option works differently now that there is no 30% credit to apply in year one.
Paying Cash for Solar in Maryland
Cash still delivers the best long-term return. You own the system, keep every net-metering credit, and hold any renewable-energy credits the system earns. Without the 25D credit, the upfront cost is higher than it was before 2026, but the state’s high rate and full-retail net metering keep an owned system the strongest option over 25 years.
Solar Loans and the 20% to 30% Dealer Fee
A loan can work, but watch the dealer fee. Many $0-down solar loans bake a dealer-fee markup of 20% to 30% of system cost into the financed amount, which is the gap between cash and loan pricing. Before signing, confirm the loan payment is lower than your current electric bill, and ask for the cash price next to the financed price so you can see the markup. A $0-down offer is rarely free once that fee is counted; for how those offers are structured, see how $0-down solar works in Maryland.
Maryland Solar Leases and PPAs
A lease or PPA is the only 2026 way to reach a federal credit. The installer owns the system and can claim the separate commercial clean-energy credit, then pass some value back through a lower monthly rate. You give up ownership, the net-metering value, and the renewable-energy credits, which go to the financier. Watch the escalator: PPA payments rise 2.9% a year, so a rate that beats your bill today can pass it in a decade.
Why Western Maryland’s Potomac Edison Rate Can Break the Math (Plus Roof Age and Shade)
Not every Maryland home is a good fit, and the cost math fails in a few clear cases.
Potomac Edison’s 14.88¢ volumetric rate stretches payback to 12.8 years, so a western Maryland homeowner has less rate to offset and a thinner margin for error than a BGE customer. Weigh that longer payback before committing, and weigh it harder if you also plan to move within five years, since the cost rarely comes back inside that window.
Roof age is the next judgment call, and the marginal case is the one to think through. Removing and resetting an array for a re-roof costs $1,500 to $5,000. A brand-new roof is clear and a 25-year-old roof is an easy no, but picture a 10-year-old roof with twelve years of life left: the array would likely outlast one re-roof cycle, so the question to ask is whether you would rather replace the roof now and mount once, or pay to pull and reset the panels mid-life. If the roof has under 8 to 10 years left, replace it first, or the savings get eaten by that teardown.
Shade depends on the same kind of question. A roof in deep afternoon shade or one that faces mostly north produces less than its rated output, which stretches payback. The harder case is a south roof that is only partly shaded, by one tree or a neighbor’s chimney: ask the installer to model production with the shade in place, and let the modeled number tip the decision rather than the compass direction alone. If trimming or removing the obstruction is on the table, that can change the answer.
Low usage shrinks the savings ceiling. Fixed costs like the customer charge, permit, and interconnection do not scale down with a small system. Below 250 kilowatt-hours a month, rooftop solar rarely pays back in Maryland, and community solar is the better option for renters, shaded roofs, and the smallest bills.
What to Ask a Maryland Solar Installer Before You Sign
Maryland’s licensing and interconnection rules are specific, so a few questions separate a competent installer from a risky one.
- Do you hold a current MHIC license? A Maryland Home Improvement Commission license is required under Business Regulation §8-301, and the grid and panel connection must run through a licensed master electrician. Ask for the license number.
- Are your installers NABCEP-certified? This is the industry standard for crews and is required for grant-program work.
- Is a panel upgrade in this quote? If your home has under 200-amp service, confirm whether the $1,200 to $2,500 upgrade is included or added later.
- What is your permission-to-operate track record with BGE and Pepco? Slow interconnection is the main delay in Maryland, so ask how long recent projects waited.
- Did you apply the sales-tax exemption? The §11-230 exemption should already be reflected in the quote, not added as a surprise.

Frequently Asked Questions
A typical 7.78 kW system runs $21,239 before incentives, based on a competitive price of $2.73 per watt. Smaller 6 kW systems start at $14,400, while larger 12 kW systems reach $36,700. With the federal credit gone for purchases, the gross price is also what you pay.
A 10 kW system runs $24,000 to $30,600 before incentives at the $2.73 per watt competitive price. Adding a 13.5 kWh battery brings it to $39,525 to $46,125, since storage adds $15,525.
No. The Residential Clean Energy Credit ended for systems installed after December 31, 2025. A lease or PPA can still reach the separate commercial clean-energy credit, claimed by the system owner, with some value passed back through a lower monthly rate.
For a purchased system, payback runs nine years on the volumetric rate solar offsets. It is nine years in BGE and Delmarva territory, and slower in western Maryland, where Potomac Edison’s lower rate stretches it to 12.8 years.
Yes. Maryland Tax-General §11-230 exempts solar equipment from the 6% sales tax, applied automatically at purchase. The state also exempts the added home value from property tax under Tax-Property §7-242.
It affects your long-term value, not your install price. House Bill 1532 closes full-retail net metering to new systems at a 3,000 MW cap or July 1, 2027, after which a lower-paying successor applies. Interconnecting before the cutoff locks full retail for the system’s life.
No. Under Tax-Property §7-242, the home value added by your solar system is exempt from real property tax, so you keep the resale value without a higher tax bill.
