Maryland Solar Guide 2026
Everything Maryland homeowners need to know: costs, incentives, net metering policy, and what makes this state unique for solar.
Quick answer
Maryland solar economics depend mainly on 4.5 average peak sun hours, an estimated $2.9/W installed cost, 16.0¢/kWh electricity, and the state's current net-metering rules.

Key fact about Maryland solar
Maryland's SREC market, $1,000 residential grant, and full retail net metering form one of the strongest incentive stacks in the Mid-Atlantic. SRECs can add $60–$80/year per kW installed.

State-specific decision guide
What to verify before signing a Maryland solar quote
In Maryland, the financial result depends on more than sunshine or the headline installation price. Confirm the export rule, program eligibility date, and interconnection timeline for your exact utility before treating a payback estimate as a promise.
Export value
This page models full retail net metering. Ask which tariff and export credit apply to your account, not only which program name appears in the proposal.
Incentive eligibility
Check equipment, income, installer, application, and placed-in-service rules before subtracting an incentive from the quote. Programs can close or change terms.
Interconnection
Budget for the published 4–10 weeks and confirm who pays for a required meter, service upgrade, or engineering review.
Source trail: production assumptions use NREL PVWatts; incentive discovery should be checked against DSIRE; electricity-market context is available from the EIA. Confirm final tax treatment with the IRS and your utility.
