What it means

In Maryland, a 6 kW system already pays back in about 14.3 years on ~$1,261/year of modeled savings, and the MD Net Metering stacks on top of that, on top of any federal credit.

How this incentive fits Maryland's solar picture

The MD Net Metering governs how Maryland credits excess solar generation sent back to the grid, one of the state's DSIRE-tracked solar policies. Eligibility is scoped to residential customers, with a stated benefit of Retail rate credit. DSIRE lists no scheduled sunset, though enabling legislation and appropriations can still be revised year to year.

That baseline is slower than most states, which raises the stakes for every incentive on the table. Maryland averages 4.5 kWh/m²/day of usable sunlight and residential rates of 16¢/kWh, producing an estimated 7,884 kWh/year and $1,261 of annual utility offset on a typical 6 kW system costing $18,000. That baseline already implies a 14.3-year simple payback and a 25-year modeled net of roughly $13,525 before this incentive - every dollar this net metering delivers compresses that payback further.

A handful of other levers are worth checking alongside this one. Maryland has 5 solar incentive programs indexed in DSIRE, including adjacent options like MD Solar Property Tax Exemption, MD Residential Clean Energy Rebate, Maryland SREC Program. The state's net-metering policy is classified as full, which governs how excess generation is credited and often decides whether a given program is worth claiming for a specific household.
