Evergreen Solar in Baltimore: Residential Rooftop Systems Without the Long Wait
Evergreen Solar is a licensed solar installer serving single-family homes and small multifamily buildings across Baltimore, with a focus on roof-mounted photovoltaic systems paired with battery storage. The company operates as a regional installer rather than a national franchise, handling design, permitting, installation, and post-installation monitoring in-house.
What Evergreen Solar actually does
Evergreen Solar designs and installs grid-tied and hybrid solar systems, meaning systems that feed excess power back to Baltimore Gas and Electric or store it in batteries for backup during outages. The company specializes in residential rooftops and works on pitched and flat roofs. They also handle system monitoring and maintenance contracts after installation.
The company does not manufacture panels or inverters; it sources equipment from mainstream suppliers (typically Enphase or SMA for inverters, panels from manufacturers like Qcells or LG) and installs them to Maryland code. They pull permits from the City of Baltimore Department of Housing and Community Development and coordinate with BGE for interconnection.
Services and pricing
A typical residential installation in Baltimore ranges from 6 to 12 kilowatts in capacity, costing between $12,000 and $28,000 before federal tax credits and Maryland state incentives. Evergreen provides free site assessments and generates a custom load calculation based on household electric bills and roof geometry.
The federal Investment Tax Credit (ITC) currently covers 30 percent of system cost. Maryland offers an additional state tax credit of up to $1,000 and net metering credits for surplus power sent to the grid. After these incentives, a typical Baltimore homeowner pays $8,400 to $19,600 for a system generating 80 to 90 percent of annual household electricity.
Maintenance contracts run $250 to $400 per year and include monitoring, inverter software updates, and annual cleaning. Most Baltimore-area systems require a roof inspection and a BGE interconnection application, both of which Evergreen coordinates. Interconnection approval typically takes 30 to 60 days; verify current BGE timelines before committing to a timeline.
How Evergreen compares to other Baltimore installers
Sunrun, a national installer, operates in Baltimore and offers similar systems but typically at 15 to 20 percent higher pricing due to corporate overhead and financing bundling. Sunrun emphasizes leasing and power-purchase agreements (you pay per kilowatt-hour used rather than owning the system), which can lower upfront costs to zero but locks you into 20-year contracts with less flexibility on system upgrades.
Evergreen sells systems outright or arranges third-party financing through Maryland-licensed lenders, so you own the equipment and benefit directly from tax credits and net metering. If you plan to stay in your home 8+ years or want to maximize incentives and own your system, Evergreen's model works better. If you prefer no upfront cost and want a contractor to handle all maintenance and module replacement, Sunrun's lease structure suits you.
Smaller local installers like Solar Energy International (Towson-based) often charge less per watt but have longer lead times (12 to 16 weeks) due to smaller crews. Evergreen typically schedules installation within 8 to 12 weeks of permit approval.
Who Evergreen suits and who it doesn't
Evergreen is a fit if you own your home, have a south- or west-facing roof with minimal shade, plan to stay for at least 7 years, and want to own the system and claim all tax credits. Homes in Canton, Fells Point, Roland Park, and Federal Hill with unshaded roofs are ideal candidates.
Evergreen is not the right choice if you rent, have significant tree shade on your roof, face roof replacement within the next five years, or prefer a zero-down lease arrangement. If your roof is less than 10 years old and south-facing, you are a good candidate; if replacement is imminent, install solar after new roofing.
What the first visit involves
Evergreen schedules a free in-home assessment where a designer photographs your roof, measures exposure, pulls your electric usage from your BGE account (you provide a recent bill), and reviews structural capacity. This visit takes 45 minutes. You receive a written proposal showing system size, expected annual output in kilowatt-hours, estimated annual savings, and net cost after federal and state credits.
If you approve, Evergreen files the City of Baltimore permit and BGE interconnection application. You sign an interconnection agreement with BGE, which typically takes 30 to 45 days. Evergreen schedules installation once permits are approved and equipment is on-site.
Installation day involves crews working on your roof for 6 to 10 hours, depending on system size. They then coordinate a BGE meter swap and inspection before your system goes live.
Hours, parking, and logistics
Evergreen operates Monday through Friday, 8 a.m. to 5 p.m., and schedules assessments by appointment. Installation work is weekday daytime only. The company is based in Federal Hill and primarily serves Baltimore City and Baltimore County. Travel fees apply for Baltimore County jobs beyond a 15-mile radius of Federal Hill; confirm this threshold when requesting an estimate.
Parking at your home during assessment and installation is your responsibility; crews typically use one vehicle and park on-street. For row homes, ensure street parking availability before scheduling.
Evergreen Solar justifies its place in Baltimore by combining local expertise on City permitting, roof structures, and BGE interconnection with transparent pricing and full system ownership, cutting through the lease-or-nothing choice national chains present to most homeowners.
