Expert reviews, BGE net metering, Maryland state incentives, and everything Baltimore homeowners need to go solar with confidence in 2026.
About This Guide
Baltimore homeowners are served by BGE (Baltimore Gas & Electric), which offers full 1-to-1 retail net metering under Maryland law. Every kilowatt-hour your solar panels produce offsets a unit of BGE electricity, and surplus credits roll over month to month indefinitely.
Maryland's incentive stack remains strong in 2026 — SRECs provide ongoing income, the $1,000 clean energy grant is available for qualifying installs, and the RCES battery grant (up to $5,000) is available until June 2026. Baltimore County also offers its own property tax credit for solar installations.
Our guide evaluates Baltimore-area installers across 8 criteria including BGE interconnection experience, NABCEP certification, warranty quality, and verified customer reviews.

Common Questions
Yes for most Baltimore homeowners. BGE's 1-to-1 net metering, Maryland SRECs, the MSAP grant (up to $7,500 for income-eligible), and the sales tax exemption combine to make solar financially compelling. The typical payback period in Baltimore is 8–11 years, followed by 14–17 years of deeply reduced electricity bills.
The average cost in Baltimore is $2.94 per watt — slightly above the Maryland state average of $2.64/W due to older housing stock requiring additional electrical work. For a typical 10 kW system the gross cost is approximately $29,400. After the MSAP grant, SREC income, and sales tax exemption, the effective net cost is substantially lower. Always get at least 3 quotes — prices vary 15–25% between installers.
BGE provides full 1-to-1 retail net metering under Maryland law. Surplus solar exports are credited at the full retail rate (~$0.165/kWh), with credits rolling over month-to-month indefinitely.
