Potomac Solar in Baltimore: Residential Installation and Financing for Homeowners

Potomac Solar is a residential solar installation company serving Baltimore and surrounding Maryland communities, specializing in rooftop photovoltaic systems for single-family homes and small multifamily properties. The company handles design, permitting, installation, and financing arrangements, positioning itself in the mid-market segment where homeowners want local installation paired with financing flexibility.

What Potomac Solar actually does

Potomac Solar designs and installs grid-tied solar arrays on residential roofs. The company conducts site assessments to evaluate sun exposure, roof condition, and structural capacity before quoting. Installation includes mounting hardware, wiring, inverters (typically string or microinverter configurations), and interconnection with Baltimore Gas and Electric (BGE). The company does not manufacture panels or inverters; it sources equipment and handles the technical and administrative work to bring systems online.

Services and pricing

Potomac Solar offers systems sized from 4 kilowatts to 12 kilowatts for typical Baltimore homes, with pricing ranging from approximately $20,000 to $55,000 before incentives. The federal Investment Tax Credit (ITC) currently covers 30 percent of system cost through 2032, reducing out-of-pocket expense materially. Maryland's tax credits and BGE's net metering program further improve economics; BGE credits excess generation at the retail electricity rate during billing periods, a significant advantage over many states' net metering structures.

The company offers three financing paths: cash purchase, a loan through partner lenders (terms vary; typical rates fall between 6 and 8 percent for qualified borrowers), and lease/power-purchase agreements (PPA) where Potomac Solar retains system ownership and the homeowner buys electricity at a fixed or slightly escalating rate. Loan terms are usually 10 to 20 years; PPA terms run 20 to 25 years. Monthly PPA payments typically range from $120 to $200 for a 7 to 10 kilowatt system in Baltimore, depending on system size and electricity baseline.

A preliminary consultation and roof evaluation are free. Detailed design and a formal proposal cost nothing if you proceed; there is no charge for the permitting and interconnection process with BGE. Verify current financing terms and incentive amounts with Potomac Solar directly, as partner lending terms and state credits change.

How Potomac Solar compares to other Baltimore installers

Baltimore-area solar installers include Sunrun (national company with local operations, PPA and finance options, higher brand recognition but less local presence), Vivint Solar (acquired by Sunrun; similar positioning), and smaller local firms like Bay Area Solar and Evergreen Energy Solutions. Sunrun's advantage is national scale, multiple financing options, and a large installed base if warranty service matters; its disadvantage is less local decision-making and sometimes higher financing costs for less-qualified borrowers. Potomac Solar's advantage lies in local presence, more flexible PPA terms, and direct communication with system designers and installers. Choose Sunrun if you value national brand backing and simplicity; choose Potomac Solar if you prefer local relationship-based service and want more control over financing structure.

System pricing across Baltimore installers is within 10 to 15 percent for comparable equipment. The difference lies in soft costs (design, permitting, labor), financing terms, and ongoing service responsiveness.

Who it suits and who it does not suit

Potomac Solar suits homeowners who own their roof, have good to excellent sun exposure (southern, eastern, or western faces without significant shade), and plan to stay in their home for at least 10 years. PPAs work especially well for homeowners with limited upfront capital but steady electricity consumption. Loans suit homeowners comfortable with debt and planning long tenure. Cash purchase suits retirees or those with capital and desire to maximize long-term savings.

Potomac Solar does not suit renters, homeowners in shade-heavy lots, or those planning to move within five years (financing costs and lease terms become economic disadvantages). It also does not serve commercial or utility-scale projects; the company focuses entirely on residential rooftop work.

What the first visit involves

Contact Potomac Solar to schedule a free site assessment. A technician visits your home, photographs the roof and surrounding landscape, notes azimuth and tilt angles, checks for obstructions or maintenance issues, and discusses your electricity bills and goals. The company uses aerial imagery and shade analysis software to model production under Baltimore's specific climate and seasonal sunlight patterns. Within a week, you receive a proposal showing system size, estimated annual production in kilowatt-hours, estimated first-year cost savings (accounting for BGE rates and incentives), payback period under your chosen financing method, and a breakdown of available tax credits. You can ask questions, request modifications, or shop competitors at this stage; no commitment is required to receive the proposal.

If you proceed, Potomac Solar handles all permitting with Baltimore City or County (depending on location) and BGE interconnection applications. You sign financing documents if using a loan or PPA. Installation typically takes one to three days, depending on system size and roof complexity. BGE inspection and final approval take 2 to 8 weeks.

Hours, parking, and logistics

Potomac Solar operates Monday to Friday, 8 a.m. to 5 p.m.; contact methods are phone and online scheduling through its website. There is no physical showroom or walk-in office in Baltimore. All interaction occurs via phone, video consultation, or on-site visits. Parking and office logistics are not applicable.

Potomac Solar's local footprint and flexibility in financing structure make it a practical choice for Baltimore homeowners evaluating solar economics within Maryland's net metering environment and available state incentives.
