Maryland solar incentives and rebates (2026)

Maryland stacks federal credit pathways (commercial Section 48E for businesses and third-party-owned residential), state-level credits/rebates where applicable, statutory tax exemptions, and utility-specific programs. Below is the 2026 picture with links to authoritative sources.

Federal credits (2026)

• Commercial Section 48E (Clean Electricity Investment Credit): Available to businesses, farms, and to third-party owners in lease/PPA structures (which can pass the benefit through as lower monthly payments). FEOC restrictions apply — see FEOC rules guide and FEOC compliant parts list. IRS — Clean Electricity Investment Credit.
• USDA REAP grants (agricultural / rural small business): Up to 50% of project cost, with low-interest loan guarantees on top. Quarterly application windows. "Before you build" rules — you must apply before construction starts. USDA — REAP Program.
• Federal 30C EV Charger Tax Credit: Up to 30% of eligible EV charging equipment + installation costs at qualifying locations. Expires for property placed in service after June 30, 2026. IRS — 30C Credit.

Maryland state-level incentives

• MD Residential Clean Energy Rebate: $1,000 grant for residential solar PV. Apply within 12 months of PTO. Funding refreshes annually; apply early.
• Property tax exemption: MD Tax-Property §7-242 — property tax exemption for solar.

MD SREC market is one of the strongest in the country — significant residual revenue. Installer must register the system in the SREC market at PTO.

Maryland battery storage incentives

MD Energy Storage Tax Credit: 30% of cost, capped at $5,000 (residential). One of the more generous state-level battery credits — verify 2026 funding.

Maryland EV charger and EV-purchase incentives (2026)

• State EV purchase rebate: MD EV Excise Tax Credit: Up to $3,000 for new EV (verify 2026 funding).

What to verify before signing in Maryland

• Contractor license: Verify with your state contractor licensing authority before signing.
• NABCEP certification: Most reputable installers carry NABCEP-certified installers on staff. Ask which crew member holds the certification.
• Insurance: General liability + workers comp + roofer's insurance separate from electrical insurance.
• References from your county: Permitting and inspection requirements vary. Ask for 2–3 references from your specific county.
• Get at least three bids: Solar bids vary by 20–35% on the same scope of work. See how to compare solar bids.

Regional installers serving Maryland

Worth a quote in the DMV side of Maryland (Montgomery / PG / Frederick) where these DC/VA-HQ regionals routinely cross the state line.

Tip: Maryland's Residential Clean Energy Rebate ($1,000 grant), the SREC market (one of the strongest in the country), and the battery-storage tax credit all stack on top of net metering. Make sure your installer files the residential-grant application within 12 months of PTO — missing the window leaves $1,000 on the table. Ask for the SREC registration confirmation as part of close-out.
