A worked example: 8 kW in Maryland
An 8 kW system — about 19 × 425-watt panels — at Maryland's assumed installed cost of $2.60–$3.40 per watt runs roughly $20,800–$27,200 before incentives. At about 1,300 kWh of production per installed kW, it would generate around 10,400 kWh per year. Valuing self-consumed electricity at the assumed $0.18/kWh retail rate and exports conservatively, first-year savings land near $1,543 — a simple payback of roughly 13–18 years.
There is no federal tax credit in that math: the Section 25D residential credit ended for systems installed after December 31, 2025. State or utility incentives, where they exist, would shorten payback from here.
Net metering in Maryland
Maryland requires retail-rate net metering statewide with annual true-up, among the stronger export policies on the East Coast.
Maryland solar incentives
Maryland offers a residential clean energy grant (historically $1,000 per system), an active SREC market, and a storage tax credit. Program funding varies year to year.
What changes a Maryland solar quote?
Equipment, roof condition, electrical upgrades, permitting, labor, system size, batteries and financing can all change the installed price. Savings also depend on the specific utility rate, how much solar electricity the home uses directly, and what the utility pays for exports.
Frequently asked questions
How much do solar panels cost in Maryland?
Using an assumed installed cost of $2.60–$3.40 per watt, a typical 8 kW home system in Maryland costs roughly $20,800–$27,200 before incentives. Smaller and larger systems scale roughly with size, though small systems cost more per watt.
Is solar worth it in Maryland?
With Maryland electricity around $0.18/kWh and production around 1,300 kWh per installed kW per year, an 8 kW system could save roughly $1,543 in year one, for a simple payback of about 13–18 years with no federal credit. Whether that is "worth it" depends on your rate plan, export compensation, roof, and how long you plan to stay in the home.
Does Maryland have net metering?
Maryland requires retail-rate net metering statewide with annual true-up, among the stronger export policies on the East Coast.
What solar incentives does Maryland offer in 2026?
Maryland offers a residential clean energy grant (historically $1,000 per system), an active SREC market, and a storage tax credit. Program funding varies year to year. Note that the federal Section 25D residential credit ended for systems installed after December 31, 2025, so state, local and utility programs are now the main incentives for purchased systems.
Is there still a federal solar tax credit in Maryland?
No — the 30% federal residential clean energy credit (Section 25D) ended for systems installed after December 31, 2025 under the One Big Beautiful Bill Act. Leased or PPA systems may still benefit indirectly because the system owner can claim the commercial 48E credit through 2027.
