Baltimore Electricity Prices
Electricity prices have climbed in Maryland, making the state’s trend relevant for Baltimore households weighing their energy options.
U.S. Energy Information Administration data show Maryland’s average residential rate rose from 13.1¢/kWh in 2021 to 17.9¢ in 2024. The U.S. average increased from 13.7¢ to 16.5¢ over the same period.
For Baltimore-area homes, rooftop solar can produce some electricity on-site, potentially reducing the amount purchased from the utility. The impact depends on system size, roof conditions, household use, and utility billing rules.
Because solar panels can generate power for many years, they may help limit exposure to future utility-rate increases. Long-term value varies with installation costs, maintenance, output, and electricity rates; savings aren’t guaranteed.
Price of Energy: Maryland vs National Average
Baltimore Area Utility Providers
For Baltimore residents served by BGE, electricity averaged 16.5¢ per kilowatt-hour in 2023, the latest utility data available; 2024 figures are not yet available.
That put BGE 0.5¢ above the 2023 national average of 16.0¢/kWh and 0.10¢ below Maryland’s 16.60¢/kWh average. The figures place BGE’s rate close to both benchmarks.
For Baltimore households, solar can provide some electricity on-site, changing how much power is drawn from the grid. Its value depends on household use and system output; it does not guarantee lower bills.

Maryland Solar Incentives
Baltimore-area homeowners may be able to reduce solar costs through Maryland programs and tax exemptions. Explore the solar incentives in Maryland listed below.
Options include an upfront solar rebate through MSAP, battery rebates through RCES, bill credits from approved community solar projects, and sales-tax exemptions for qualifying solar equipment and solar-generated electricity.
The federal 30% residential tax credit ended under the Big Beautiful Bill, but Maryland incentives remain. LightReach leasing lets Palmetto handle commercial ITC, with savings reflected in lower monthly payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Maryland Solar Access Program (MSAP), FY27 | Solar rebate | Eligible Maryland homeowners can receive $750 per kW of installed residential solar capacity, up to $7,500, with an approved reservation required before installation. | Learn More |
| Residential and Commercial Energy Storage (RCES) Program, FY27 | Battery storage rebate | The open FY27 state program offers rebates for eligible grid-connected battery systems, but its public page does not specify a verified per-project rebate amount. | Learn More |
| Maryland Community Solar Program | Community solar bill credits | Maryland utility customers can subscribe to an approved community solar project and receive utility-bill credits for their share of its output. | Learn More |
| Maryland sales and use tax exemption for solar equipment | Sales tax exemption | Qualifying solar energy equipment is exempt from Maryland sales and use tax when used for specified solar heating, cooling, electricity-generation, or hot-water purposes. | Learn More |
| Maryland sales tax exemption for qualifying solar-generated electricity | Sales tax exemption | Maryland law provides a separate sales-tax exemption for electricity generated by solar equipment for use in eligible residential property. | Learn More |
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 Baltimore
Verify the license
In Maryland, solar panels installed for a homeowner must be mounted by an MHIC-licensed home-improvement contractor. Only MHIC-licensed contractors may contract directly with homeowners for home-improvement work, although a subcontractor working for one may not need a separate MHIC license. Look up the contractor through the Maryland Home Improvement Commission license search. The person connecting the panels to your home’s electrical system or the grid must hold an electrician’s license issued by the local jurisdiction; an MHIC license alone does not authorize electrical work. Ask who will do each part of the job and verify the relevant licenses.
Look for certified installers
Ask whether the people designing or installing your system hold a current credential from the North American Board of Certified Energy Practitioners (NABCEP), and which credential applies to their role. You can also ask about manufacturer certifications for the proposed equipment. These may show product-specific training or qualification, but they are not a substitute for Maryland contractor and electrician licensing. Check who holds each credential and whether it covers the work being proposed.
Compare quotes the same way
Request written proposals with the same details so you can compare scope, equipment, costs and assumptions. Check:
- System size: proposed capacity in kilowatts (kW) and price per watt.
- Equipment: panel and inverter brands and models.
- Production: estimated annual energy in kilowatt-hours (kWh), and the assumptions behind the estimate.
- Warranties: panel product and performance, inverter, workmanship, and roof penetrations; compare coverage, duration and exclusions.
- Project responsibilities: who obtains permits and submits the utility interconnection request.
- Payment: total cost or monthly payment, financing terms, and any payment escalator.
Have each installer explain differences in system size, production estimates, equipment or included work before choosing.
Permits, interconnection and your HOA
Building and electrical permits are handled by your local jurisdiction, typically the county and sometimes a municipality; confirm local requirements and who will obtain approvals. You or the installer submits the interconnection request to the electric utility that owns the distribution system. Depending on where you live, that may be Baltimore Gas & Electric Co, Potomac Electric Power Co, The Potomac Edison Company, or Delmarva Power. Ask the installer to identify the utility and explain who handles the request and local electrical-code approval.
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 proposed installation cost by at least 5% or reduces projected generation by at least 10%, with documentation from a qualifying independent solar-panel design specialist required. The rule allows restrictions on common areas and specified historic properties. A written solar easement may be negotiated and must be recorded in county land records; it is not automatic. If HOA rules may affect your project, ask what review is needed and get the details in writing.
Red flags
- Pressure to sign the same day or accept terms before you have time to compare proposals.
- Unlicensed crews—or out-of-state crews when the contractor cannot clearly identify who is responsible and verify required local licensing.
- Vague production estimates without an annual kWh figure and explanation of assumptions.
- A large upfront deposit without a clear written payment schedule and description of what it covers.
- Promises that you can claim federal homeowner tax credits for a 2026 purchase; those credits ended December 31, 2025.
Leasing Solar Panels
For Baltimore homes served by Baltimore Gas & Electric (BGE), Palmetto offers a solar Power Purchase Agreement (PPA). A PPA charges for the electricity your system produces at an agreed price per kilowatt-hour, so payments can vary with seasonal production. A solar lease instead uses a fixed monthly payment; compare buying and leasing solar.
With a PPA, you can go solar without paying the full system cost upfront. Unlike a cash purchase, where you own the equipment and arrange maintenance, a LightReach PPA includes system service and maintenance under the agreement, leaving those responsibilities with the provider.
Terms and eligibility depend on your home and utility. Learn more about Palmetto LightReach and review the agreement for payment, service, and ownership details.
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. Baltimore Gas & Electric (BGE) offers 1:1 net metering for eligible solar customers. Electricity sent to the grid earns kilowatt-hour credits that can offset electricity drawn from the grid, and unused credits carry over from month to month.
In May, BGE settles remaining credits at a variable rate of about $0.05–$0.07 per kWh, then resets the credit balance to zero. BGE’s three time-of-use rate schedules are not eligible for net metering.
Yes, purchased solar panels may increase a Baltimore home’s value, but the amount depends on the property and market. Zillow’s study found homes with solar panels sold for approximately 4.1% more on average; this is not a Baltimore-specific estimate or a guaranteed increase.
This potential value applies to solar systems the homeowner owns, not leased or third-party-owned systems. A lease or PPA may affect resale differently because the buyer may need to assume the agreement. Roof condition, system age, and performance can also influence buyer interest.
In Baltimore, homeowners can go solar with a LightReach lease for a low fixed monthly payment and no upfront cost. The calculator above estimates $124 per month for a typical 10.25-kW system; estimates range from $90 to $168 per month by home size.
A cash purchase is another option. The calculator estimates $29,165 for a typical system, with home-size estimates from $21,929 to $38,744. The federal 30% residential solar tax credit is no longer available for cash purchases following the 2025 federal law change. See the calculator above for pricing details.
Leasing solar means a provider owns and installs the panels, while you pay a monthly amount to use the system. LightReach has no upfront cost; one payment covers the panels, installation, monitoring, maintenance, and protection program, including a 90% Production Guarantee.
For a typical 10.25 kW system in Baltimore, the estimated lease payment is about $124 per month, based on Maryland’s 1,160 kWh/kW/year production ratio and $0.125/kWh rate. Payments are typically below the current electricity bill, so savings may start right away; actual bills and savings vary.
Yes, solar can make sense in Baltimore, where Maryland averages about 4.8 peak sun hours daily and electricity rates have risen. Whether panels are worthwhile for your home depends on roof condition, shade, energy use, system cost, and utility billing rules; savings are not guaranteed.
LightReach, Palmetto’s solar lease program, removes the upfront cost barrier entirely: homeowners can go solar with no money down and start saving from day one. Compare the agreement’s monthly costs with your expected utility-bill impact.
There isn’t one best solar installer for every Baltimore home; roof condition, shade, energy use, price, and service terms all matter. Palmetto Solar is an experienced option for Baltimore-area homeowners, with 2,377 installations completed in Maryland since 2020 and a network of local installation professionals.
We offer financing options, but compare the full costs and terms, equipment, production estimates, warranties, and maintenance responsibilities. A good proposal should account for your roof and household electricity use, not rely on a one-size-fits-all estimate.
Solar can be financially worthwhile in Baltimore when your panels produce enough electricity to lower utility costs. With a LightReach lease, there is no upfront investment, and the monthly lease payment is typically less than your current electricity bill, so savings can begin once the system is operating.
Your actual savings depend on your roof, energy use, system production, and BGE billing rules. Compare the lease payment plus any remaining utility charges with your current bill to estimate your household’s net savings.
