Frederick Electricity Prices
Electricity rates can shape a Frederick household’s energy costs—and Maryland’s recent trend offers useful context.
EIA electricity data show Maryland’s average residential rate climbed from 13.1¢ per kWh in 2021 to 17.9¢ in 2024, about a 37% increase. The 2024 statewide figure also exceeded the U.S. average of 16.5¢.
A home solar system can generate electricity on-site, potentially reducing how much power a household buys from its utility. The impact in Frederick depends on system output, household use, and utility rules for billing excess generation.
Over time, using solar may help offset exposure to utility rate increases, but it does not guarantee lower bills. Overall value depends on installation cost, roof condition and shade, energy use, system performance, and applicable utility policies.
Price of Energy: Maryland vs National Average
Frederick Area Utility Providers
For Frederick, MD, the available comparison is for Potomac Edison. The latest figures provided are from 2023; 2024 data is not yet available.
Potomac Edison’s 2023 rate was 11.7¢ per kWh, below Maryland’s 16.6¢ and the national average of 16.0¢. These figures compare one utility’s rate with broader averages; they do not show why the rates differ.
For solar installation in Frederick, MD, Potomac Edison’s lower rate is a useful baseline. Savings depend on how much electricity a system offsets and household use; solar can reduce grid purchases but may not eliminate all charges.

MSAP offers income-eligible Maryland homeowners a rebate of $750 per kW of installed solar capacity, up to $7,500 per household. FY27 income limits vary by household size, from $136,785 for one person to $257,910 for eight people; check the official program page for the full table and other eligibility rules.
Use a contractor on the Maryland Energy Administration’s participating-contractor list and obtain an approved rebate reservation before installation. A payment request is made after the system is installed and interconnected with the utility. The FY27 application deadline is May 31, 2027, at 3 p.m. ET, or earlier if funds are requested.
RCES provides state support for grid-connected battery storage at residential properties, as well as commercial properties and nonprofits. MEA anticipates up to $4 million in FY27 funding, but the public program page does not state a per-kWh or per-project rebate formula; check the current application portal for the actual award terms before budgeting.
An upfront reservation must be approved before installation. The FY27 deadline is May 31, 2027, at 3 p.m. ET, or earlier if funds are requested. Funding is expected to prioritize systems enrolled in utility-run virtual power plant pilots; confirm any participation requirements and compensation with the program and your utility.
Community solar lets homeowners receive bill credits without installing panels on their own property. Subscribers sign a contract with a project’s subscriber organization, and the utility applies credits based on the subscription and project output.
Review the subscription price, bill-credit calculation, contract length, and cancellation terms before enrolling; subscription charges can reduce or outweigh savings. Under program rules, most projects must allocate at least 40% of output to low- and moderate-income subscribers, who must receive at least 10% savings. The PSC does not set individual subscription prices.
Maryland exempts qualifying solar energy equipment from state sales and use tax when it is used to heat or cool a structure, generate electricity for use in a structure or supply to the grid, or provide hot water. The exemption can reduce the upfront cost of eligible solar equipment.
Do not assume that every separately purchased battery automatically qualifies: the statute’s treatment depends on how the equipment is classified and used. Ask the seller or Maryland tax authorities how the exemption applies to a particular solar-plus-storage purchase.
Maryland law separately exempts qualifying electricity generated by solar equipment for use in eligible residential property from sales tax. This is distinct from the sales and use tax exemption for qualifying solar equipment itself.
The exemption concerns qualifying solar-generated electricity; it is not a battery rebate or a general exemption for all electricity purchases. Check the statute and applicable billing or tax treatment to determine how it applies to your property.

How to Choose a Solar Installer in Frederick
Verify the license
In Maryland, solar panels installed on a homeowner’s property must be mounted by an MHIC-licensed home-improvement contractor. Only an MHIC-licensed contractor may contract with you for home-improvement work; a subcontractor working for one may not need a separate MHIC license. The person connecting the system to your home’s electrical system or the grid must have an electrician’s license issued by the local jurisdiction. An MHIC license does not authorize electrical work. Look up a contractor through the MHIC license search, and ask who is responsible for the electrical work and what local electrician’s license they hold.
Look for certified installers
Ask whether the people designing and installing your system hold relevant NABCEP certifications or manufacturer certifications for the equipment proposed. These credentials can help you assess training or product-specific qualifications, but they do not replace the Maryland contractor and electrician licenses required for the work. Ask which crew will do the installation, and verify that the people and companies named in the contract match the answers you receive.
Compare quotes the same way
Request written quotes with the same assumptions and compare the details—not just the headline price. Ask each installer to explain how the system size and production estimate were calculated, and what is included in the price or payment.
- System size in kW and price per watt.
- Panel and inverter brands and models.
- Estimated production in kWh per year, plus the assumptions behind it.
- Warranty terms for panel product and performance, inverter, workmanship, and roof penetrations.
- Who handles building and electrical permits and the utility interconnection request.
- Total cost or monthly payment, financing or lease terms, and any payment escalator.
Compare warranty durations and exclusions, and ask who you contact if equipment or installation issues arise. Make sure the production estimate and payment terms are written into the documents you review.
Permits, interconnection and your HOA
Building and electrical permits are handled by the local jurisdiction—typically the county, sometimes a municipality—so confirm requirements where your home is located. You or the installer submits the interconnection request to the utility that owns the distribution system. Maryland utilities include Baltimore Gas & Electric Co, Potomac Electric Power Co, The Potomac Edison Company, and Delmarva Power; confirm which serves your address and who will submit the request.
Maryland law limits unreasonable restrictions on solar collectors on a roof or exterior wall you own or exclusively use. A restriction is unreasonable if it raises installation cost by at least 5% or cuts projected generation by at least 10%; documentation from a qualifying independent solar-panel design specialist is required. The rule allows restrictions on common areas and specified historic properties. Review your HOA requirements early, and check the law for details. A solar easement is not automatic; it may be negotiated in writing and must be recorded in county land records.
Red flags
- Pressure to sign the same day, before you can review the contract and compare offers.
- An installer that will not identify the MHIC-licensed contractor, electrical license holder, or installation crew. Verify licenses rather than assuming an out-of-state crew is qualified.
- Vague production estimates, or reluctance to explain the assumptions and warranties in writing.
- A large upfront deposit without clear, written terms for what it covers and when payments are due.
- Promises that homeowners can claim federal tax credits for purchases made in 2026; homeowner credits ended December 31, 2025.
Leasing Solar Panels
For Frederick homes served by Potomac Edison, a solar power purchase agreement (PPA) is available. Instead of a fixed lease payment, you pay an agreed price for each kilowatt-hour the system produces, so payments can vary by season.
A PPA can help you go solar without paying the full system cost upfront. The provider owns the panels and handles covered maintenance under the agreement, unlike a cash purchase, where you own the system and arrange and pay for upkeep.
A lease usually has a fixed monthly payment; a PPA bill changes with production, though yearly costs may be similar. Compare buying and leasing solar, or learn about Palmetto’s LightReach options.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!

Yes. Frederick, MD residents served by Potomac Edison have access to 1:1 net metering. Electricity sent to the grid earns credits on a per-kilowatt-hour basis, which can offset electricity drawn from the utility later.
Unused credits carry over from month to month. Potomac Edison settles remaining excess credits in May at the generation portion of the rate—about $0.05 to $0.07 per kWh—and resets the account to zero. Rules can vary by utility, so check which provider serves your address.
Yes, owned solar panels may increase a home’s resale value in Frederick, MD. A Zillow study found homes with solar panels sold for about 4.1% more. That is a national estimate, not a guaranteed local increase; value depends on factors such as system condition, energy savings, and buyer demand.
This potential increase applies to purchased systems the homeowner owns, not leased or third-party-owned (TPO) systems. With a lease or PPA, a buyer may need to assume the agreement, which can affect resale differently.
In Frederick, homeowners can go solar with a LightReach lease for no upfront cost and a fixed monthly payment. The calculator above estimates $90–$168 per month depending on home size; its typical 2,000–3,000-square-foot home estimate is $124 per month.
As an alternative, the calculator estimates a cash purchase at $21,929–$38,744, with $29,165 for a typical-size system. The federal 30% tax credit is no longer available for residential cash purchases following the 2025 federal law change. See the calculator above for specific estimates.
With a solar lease, the provider owns and installs the panels, and you pay a set monthly amount for the system’s electricity. In Frederick, a typical 10.25 kW system is estimated at about $124 per month, with no upfront cost. Your actual payment depends on your home and lease terms.
Palmetto’s LightReach lease includes installation, monitoring, maintenance, and a protection program with a 90% Production Guarantee in one payment. Lease payments are typically lower than a household’s current electricity bill, so savings may begin from day one; utility charges may still apply.
Yes, solar can make sense in Frederick, MD when a roof gets suitable sun and expected bill savings compare favorably with system costs. Production rises during long summer days and falls in cloudy winter months. Roof condition, shade, household electricity use, and utility billing rules all affect a system’s value.
Eligible homeowners may qualify for Maryland’s MSAP rebate, which requires approval before installation. Palmetto’s LightReach solar lease removes the upfront cost barrier entirely: homeowners can go solar with no money down and start saving from day one.
Solar can be worth it financially when the cost of the system is offset by lower electricity costs. With LightReach, there’s no upfront investment, and the monthly lease payment is typically less than a homeowner’s current electricity bill, so savings can begin once the system is operating.
In Frederick, actual savings depend on your home’s energy use, roof sunlight and shade, lease terms, and any remaining Potomac Edison charges. Compare the lease payment plus your expected utility bill with what you pay now.
Solar panels in Frederick, MD, are generally low maintenance. Rain usually rinses off light dust, but check for debris or shading and monitor system output for changes.
With a LightReach agreement, Palmetto owns the system and handles maintenance, monitoring, and repairs at no extra cost. The agreement also includes a 90% Production Guarantee.
