Is there a state solar tax credit in Maryland?

Maryland exempts solar systems from sales tax and property tax reassessment, and residents can earn ongoing revenue through the state's SREC market. A separate 30% state tax credit (capped at $5,000) applies to battery storage installed with or without solar.

What's the typical payback period for solar in Maryland?

Most Maryland homeowners see a payback period of 9-12 years based on current electricity rates and remaining incentives, since the federal 30% tax credit no longer applies to cash or loan purchases in 2026.

Does the federal solar tax credit still apply here?

No — the 30% federal Residential Clean Energy Credit (Section 25D) expired for cash and loan purchases on December 31, 2025. It only remains available indirectly through solar leases and PPAs, where the financing company claims a separate commercial credit.
