How long is solar payback in Maryland?

Solar payback in Maryland typically runs 7–12 years depending on your electricity rate, system size, sun hours, and whether you qualify for the federal 30% Investment Tax Credit plus any Maryland state incentives. Use the calculator above for a personalized estimate.

What solar incentives are available in Maryland in 2026?

All Maryland homeowners qualify for the federal 30% Solar Investment Tax Credit (ITC) on the gross system cost. Maryland may also offer a state tax credit, rebates from your utility, or favorable net metering. See the calculator inputs above for Maryland-specific values.

Is net metering available in Maryland?

Net metering rules vary by state and utility. Maryland has its own rules — full retail credit, time-of-use rates, or buyback programs. The calculator above factors in Maryland's effective net metering value when estimating your monthly bill offset.

How many sun hours does Maryland get?

Maryland's average peak sun hours per day (NREL TMY3 data) determines how much solar your system can generate. The calculator above uses Maryland-specific irradiance to size the system from your monthly electricity bill.

Should I buy solar panels or lease them in Maryland?

Buying outright (cash or loan) lets you claim the 30% federal ITC and any Maryland state credit, and you own the energy. Leasing or PPAs let the installer take the credit but you avoid upfront cost. For long-term value in Maryland, ownership almost always wins.

Solar Payback in Maryland (2026) — $1K Rebate + SREC + Federal 30%

Maryland has solid solar economics — typical 7-10 year payback. The state runs an active SREC (Solar Renewable Energy Certificate) market paying solar owners $30-$50/MWh of production for 15 years, on top of a flat $1,000 state rebate and full retail net metering. The federal 30% ITC stacks on everything.

4. Property tax exemption

Maryland exempts solar's added value from property tax assessment.

5. Sales tax exemption

MD solar PV is sales-tax-exempt.

6. Full retail net metering

How to use the Maryland solar calculator above

The state is pre-selected. Adjust if needed.
Enter your typical monthly electric bill (averaged across the year).
The calculator auto-fills your state's average electricity rate and peak sun hours — override the electricity rate with your real $/kWh from your bill if you know it.
Adjust the system cost per watt based on quotes from local installers. Maryland averages are typically within the $2.50–$3.50/W range for cash installs.
The output shows estimated system size, net cost after federal and state credits, year-1 savings, and 25-year cumulative savings.
