Expert reviews, Pepco net metering, Maryland state incentives, and everything Gaithersburg MD homeowners need to go solar with confidence.
About This Guide
Gaithersburg leads Maryland in 25-year solar savings at $91,140 — the highest of any city we cover. Pepco's high electricity rates (~$0.18/kWh) mean every net metering credit and every solar kilowatt-hour is worth more here than in lower-rate utility territories.
Maryland's incentive stack remains strong in 2026 — SRECs provide ongoing income, the MSAP grant offers up to $7,500 for income-eligible homeowners, and the RCES battery grant (up to $5,000) is available until June 2026. Pepco's 1-to-1 net metering credits roll over indefinitely month to month.
Our guide evaluates Gaithersburg MD installers across 8 criteria including Pepco interconnection experience, NABCEP certification, warranty quality, and verified customer reviews.

Yes for most homeowners. Maryland SRECs, MSAP grant (up to $7,500 income-eligible), sales tax exemption, Montgomery Co. Tax Credit, and Pepco's 1-to-1 net metering combine to make solar financially compelling with typical payback periods of 7–12 years.
