Bethesda Electricity Prices
Electricity rates have climbed in Maryland, making long-term household energy costs worth a closer look.
Maryland’s average residential rate rose from 13.1¢ per kWh in 2021 to 17.9¢ in 2024. The national average increased from 13.7¢ to 16.5¢ over the same period.
For Bethesda homeowners, rooftop solar can generate electricity at home and reduce the amount bought from the grid. Results depend on roof condition, shade, household energy use, and utility rules.
Over time, generating some electricity at home may help limit exposure to changing grid rates. A system’s long-term value depends on its cost, energy production, and available bill credits.
Price of Energy: Maryland vs National Average
Bethesda Area Utility Providers
In Bethesda, Pepco supplies electricity. The latest figures available here are for 2023: Pepco’s rate was 18.2¢ per kilowatt-hour, above Maryland’s 16.60¢ and the national average of 16.0¢. 2024 figures are not yet available.
These comparisons show Pepco’s rate was higher than both averages in 2023. The figures alone do not explain why: they do not include utility cost details or rate-setting information that could account for the difference.
When electricity costs more, using rooftop solar to produce some of a home’s electricity may reduce how much it needs to buy from Pepco. The value depends on a home’s solar production and electricity use.

Maryland Solar Incentives
Bethesda homeowners may be eligible for Maryland programs that can help offset solar costs. Explore the solar incentives in Maryland listed below.
Options include a residential solar rebate, battery-storage rebates, community-solar bill credits, and sales-tax exemptions for qualifying solar equipment and eligible solar-generated electricity. Eligibility and terms vary by program.
The 30% residential tax credit was eliminated under the Big Beautiful Bill; Maryland incentives remain. With LightReach leasing, Palmetto handles the commercial ITC and passes savings through as lower 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 Bethesda
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 with homeowners for home-improvement work, though a subcontractor working for one may not need a separate MHIC license. The person connecting the panels 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. Ask which contractor is responsible for your project and who will do the electrical connection, then check the contractor through the Maryland MHIC license lookup and confirm the electrician’s license with your city or county.
Look for certified installers
Ask whether anyone on the proposed project team holds a NABCEP certification, and verify the credential through NABCEP. Find out who holds it and what role they will have on your project; certification is useful information for comparing qualifications, but it does not replace Maryland’s licensing requirements. If an installer cites manufacturer certifications, ask which manufacturer issued them, which equipment they cover, and whether they apply to design, installation, or both. Compare the actual credentials and project responsibilities rather than relying on a certification label alone.
Compare quotes the same way
Request written proposals with comparable details. If system sizes, equipment, or payment structures differ, clarify those differences before choosing. Compare:
- System size: rated capacity in kilowatts (kW), and the quoted price per watt.
- Equipment: panel and inverter brands and models.
- Production: estimated electricity generation in kilowatt-hours per year (kWh/year), with the assumptions behind the estimate explained.
- Warranties: panel product and performance, inverter, workmanship, and roof penetrations; ask who provides each warranty and what it covers.
- Project responsibilities: who obtains permits and submits the utility interconnection request.
- Cost: total cost or monthly payment, plus any escalator and how it changes payments.
Permits, interconnection and your HOA
Building and electrical permits are handled by the local jurisdiction—typically the county, sometimes a municipality—so confirm local requirements and ask who will obtain them. You or the installer submits the interconnection request to the electric utility that owns the distribution system. In the Bethesda area, identify whether service is from Baltimore Gas & Electric Co, Potomac Electric Power Co, The Potomac Edison Company, or Delmarva Power, and confirm the process for that utility. Local or municipal electrical-code approval is part of utility 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. Common areas and specified historic properties are exceptions. A written solar easement may be negotiated and must be recorded in county land records; it is not automatic.
Red flags
- Pressure to sign the same day instead of time to review the proposal and contract.
- Unlicensed or out-of-state crews without clear answers about the responsible contractor, licenses, and who performs electrical work. Verify credentials rather than assuming location alone establishes qualification.
- Vague production estimates or refusal to explain the estimate’s assumptions.
- A large upfront deposit without clear written terms for what it pays for and when.
- Promises of federal homeowner tax credits for purchases in 2026. Homeowner credits ended December 31, 2025.
Leasing Solar Panels
For many Bethesda homes served by Pepco, Palmetto offers a solar power purchase agreement (PPA). You pay for the electricity the system produces at an agreed price per kilowatt-hour, rather than buying the equipment upfront. Local availability and final terms depend on your home and utility.
A PPA payment can vary with seasonal production: panels often generate more in summer and less in winter. A lease typically has a fixed monthly payment; learn more about the differences between buying and leasing solar.
Compared with paying cash, a PPA can avoid the large upfront purchase and the responsibility of maintaining equipment you own. The system provider owns and maintains the panels under the agreement, subject to its terms. Explore Palmetto LightReach for program 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. Bethesda residents served by Pepco can use Maryland’s 1:1 net metering. Electricity sent to the grid earns credits on a kilowatt-hour basis, and unused credits can roll over from month to month.
Pepco settles remaining excess credits each May at a variable rate, listed at about $0.05–$0.07 per kWh, then resets the credit balance. Check your current utility terms for details.
Solar panels may increase a Bethesda home’s value when the homeowner owns the system. Zillow’s study found homes with solar sold for approximately 4.1% more on average. That national estimate isn’t a guarantee for an individual home; buyers may also consider system age, roof condition, and potential Pepco bill savings.
This value finding applies to purchased or otherwise owned systems, not leased or third-party-owned (TPO) panels. A leased system may affect resale differently because the buyer may need to assume its agreement.
In Bethesda, homeowners can go solar with a LightReach lease for no upfront cost and a low fixed monthly payment. The calculator above estimates about $124 per month for a medium home; estimated payments range from $90 to $168 monthly by home size.
A cash purchase is another option: the calculator estimates $29,165 for a typical 10.25-kW system, with prices varying by system size. 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 specific estimates.
With Palmetto’s LightReach lease, Palmetto owns the panels; there is no upfront cost. One monthly payment includes the system, installation, monitoring, maintenance, and protection, including a 90% production guarantee.
For a typical 10.25-kW Bethesda system, the estimated lease payment is about $124/month, based on Maryland’s 1,160 kWh/kW/year production ratio and $0.125/kWh. Actual terms vary by home. The payment may be below your current electricity bill, though Pepco charges can remain.
There isn’t one best solar company for every home, but Palmetto Solar is a choice for Bethesda homeowners to consider. We have completed 2,377 installations in Maryland since 2020 and work with a national installation network.
We offer financing options, including lease and power purchase agreement plans. Compare project terms and check how your roof’s condition and shade, household energy use, and Pepco’s rules affect the system’s cost and expected production.
Yes, solar can make sense for some Bethesda, MD, homes. Pepco’s reported 2023 rate was 18.2¢ per kWh, and rooftop panels can reduce electricity bought from the grid. Whether installation is worthwhile depends on your roof’s condition and shade, household energy use, system cost, and utility credits; production is typically lower during Bethesda’s shorter winter days.
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. Review the agreement’s payment terms and estimated savings for your home.
Maryland’s FY27 Solar Access Program offers income-eligible households $750 per installed kW, up to $7,500, with rebate reservation required before installation. The FY27 battery program supports eligible grid-connected storage; check current award terms. Community-solar subscriptions can earn utility-bill credits.
Qualifying solar equipment and eligible solar-generated electricity are exempt from Maryland sales tax. The federal 30% residential credit is unavailable for cash purchases. Palmetto says it claims the commercial ITC for LightReach leases and passes the savings through as lower payments.
