Why solar in Maryland

Maryland is one of the better residential solar markets on the east coast, and it is unusual in paying homeowners through two separate channels rather than one. Net metering credits exported electricity on your bill, and separately your system earns Solar Renewable Energy Certificates, one for every megawatt-hour generated, which you can sell into a real market. Maryland's Renewable Portfolio Standard law requires 14.5 percent solar, 2.5 percent off-shore wind and 50 percent total renewables by the end of calendar year 2030, and that requirement is what creates buyers for those certificates. The Maryland Energy Administration also pays a flat $1,000 rebate for a qualifying residential system. The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase in 2026 receives no federal credit, though a lease or power purchase agreement provider may still claim the surviving commercial Section 48E credit.

Incentives & rebates

Net metering: Full retail net metering (PSC-administered)

Maryland credits exported solar at the retail electricity rate, and the framework is set by statute and administered by the Public Service Commission, so it is broadly the same whether you are served by BGE, Pepco, Delmarva Power or Potomac Edison. Credits accumulate through the year and there is an annual reconciliation, so ask your utility what happens to a remaining surplus at that point and what options you have for carrying credits forward instead. Net metering is separate from and stacks with SREC income.

Frequently asked questions

How much do solar panels cost in Maryland?
Maryland solar averages roughly $2.95 per watt installed, so a typical 7 kW system runs about $20,000 before incentives. The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase no longer receives it. The Maryland Energy Administration $1,000 rebate and ongoing SREC income still apply.
What incentives are available in Maryland?
A flat $1,000 Maryland Energy Administration rebate for a qualifying system installed by a NABCEP certified installer, full retail net metering, Solar Renewable Energy Certificates earned at one per megawatt-hour and sold into a market, and exemptions from state sales and use tax and from real property tax under Tax-Property Section 7-242.
What are SRECs and how do I earn them?
One megawatt-hour of production generates one SREC, so a system producing 12,000 kilowatt-hours a year earns about 12. Your system must be registered with the Maryland Public Service Commission, and within 30 days of registering you need to go to PJM Interconnection's GATS for next steps. SRECs have a life of 3 years and can be held, sold directly to a supplier, or assigned to an aggregator.
Is solar worth it in Maryland?
For most homes with a suitable roof, yes. Full retail net metering plus SREC income plus the $1,000 state rebate is a stronger stack than most states offer, which is why Maryland pays back faster than its sun hours alone would suggest. SREC prices move with the market, so treat quoted SREC income as a forecast rather than a fixed payment.
