Maryland Solar Incentives, Cost & Payback (2026)

Cost of solar in Maryland

For a typical household in Maryland consuming around 11,054 kWh per year, you'll need roughly a 7.73 kW system to offset your usage. At an estimated average cost of$3.00/watt, the gross price tag lands near $23,196 before factoring in any incentives.

Note that since the federal residential clean energy credit (§25D) doesn't apply to new residential installations completed after the end of 2025, your net cost on a standard cash or loan purchase moving into 2026 is often the same as the gross cost — though Maryland-specific programs and ongoing SREC revenue can still dramatically improve the financial picture.

Net metering / export rules

Maryland is one of the states still offering traditional, full retail net metering. When your solar panels produce more electricity than your home is actively using, the surplus goes back onto the grid. Your utility will credit you for this excess power on a 1-for-1 basis at the exact same rate they charge for electricity.

Because your credits rollover every month, your summer overproduction seamlessly offsets your winter energy bills. Utilities cannot add arbitrary standby fees to net-metered residential customers in Maryland.

Within each monthly billing cycle, exported kWh offset consumption 1-for-1 at the customer's full retail rate (statute requires an identical rate structure to non-generating customers). If generation exceeds consumption for the month, the surplus (net excess generation) is banked as a kWh credit; most customers may carry that credit forward indefinitely, and any credit paid out in cash (e.g., at account closure or under the 12-month accrual option) is paid only at the generation/commodity portion of the rate, not the full retail rate.

Batteries & Energy Storage

While Maryland's 1-for-1 net metering means you don't strictly need a battery for maximum financial payback, many homeowners still choose to install one for backup power and grid independence.
