MJ Solar Power in Baltimore: Residential Installation with Performance Guarantees
MJ Solar Power is a locally owned solar installer focused on residential rooftop systems across Baltimore and surrounding counties. The company handles design, permitting, installation, and post-installation monitoring for homeowners seeking to reduce electricity costs through solar energy.
What MJ Solar Power actually is
MJ Solar Power operates as a full-service solar contractor rather than a broker or financing platform. The company employs its own installation crews and handles the engineering and permitting process directly, which means homeowners work with the same team from initial site survey through system activation. The business is Maryland-licensed and insured, a requirement for any solar installer in the state. Most of their work centers on Baltimore City and Baltimore County residential properties, though they occasionally service Howard and Anne Arundel counties.
Services and pricing
MJ Solar Power offers grid-tied photovoltaic systems sized to match a household's annual electricity consumption. A typical residential system ranges from 5 kilowatts to 12 kilowatts depending on roof space, sun exposure, and household usage patterns.
System pricing generally falls between $2.50 and $2.80 per watt after accounting for the federal Investment Tax Credit (currently 30 percent), though the final per-watt cost depends on system size, roof complexity, and any electrical upgrades needed. A 7-kilowatt system, common for a Baltimore rowhouse or modest detached home, typically runs $13,000 to $16,000 post-tax-credit. Larger 10-kilowatt systems can exceed $22,000 after the credit. These figures are current but shift with equipment costs and incentive changes; request a written quote to lock pricing.
The company includes a 25-year manufacturer's warranty on panels and a 10-year warranty on inverter components and workmanship. System monitoring via smartphone app is included at no additional cost, allowing homeowners to track real-time and historical production data.
MJ Solar Power handles all Maryland interconnection paperwork with BGE (Baltimore Gas and Electric) or other local utilities, a process that typically takes 4 to 8 weeks after installation. Permitting fees and utility interconnection application costs are generally bundled into the system price rather than charged separately.
How it compares to other Baltimore-area solar installers
Baltimore has several solar installers of varying scales. Vivint Solar and Sunrun operate as national platforms that often use subcontractors for installation; they tend to handle financing and leasing more aggressively than outright purchase, which can shift long-term savings. Local alternative Sage Energy Group similarly emphasizes financing options and operates across multiple states.
MJ Solar Power's primary advantage is local ownership and direct employment of installation crews. Homeowners avoid the financing-first sales model common at larger platforms and work directly with decision-makers for system design. This structure usually results in faster permitting feedback and easier communication during the install phase.
Choose MJ Solar Power if you own your home outright or plan to purchase your system and want a local installer who will design the system to your roof and usage rather than to financing terms. Choose a national platform if you prefer minimal upfront capital and want to compare lease, power-purchase agreement, and loan options side by side.
Who it suits and who it does not suit
MJ Solar Power suits Baltimore homeowners with 4+ hours of daily peak sun exposure (most of the city qualifies), southern- or west-facing roof space, and an electric bill over $100 per month. Rowhouses with small roofs often accept slightly smaller systems; detached homes with ample south-facing roof typically maximize their savings.
The company does not install on commercial rooftops or handle battery storage (Powerwall or Enphase) as standalone add-ons, though batteries can sometimes be incorporated at the design stage. Renters and condo dwellers in Baltimore cannot use their services unless they own the roof space outright.
What the first visit involves
An initial consultation includes a site survey where the installer photographs the roof, measures dimensions, checks for shading from trees or buildings, and pulls utility bills to understand historical usage. This visit is free and typically takes 30 to 45 minutes. The installer uses this data to model several system sizes and show estimated annual production and 25-year savings using Maryland solar irradiance data and current BGE electricity rates.
A written proposal follows within 3 to 5 days, including system specifications, equipment brands, financing options if applicable, and a breakdown of federal and state incentives. The company also identifies whether the roof will need repairs or reinforcement before installation, a common finding on older Baltimore homes.
Once a contract is signed, permitting begins. Installation typically occurs 6 to 10 weeks after contract execution, depending on permit processing and BGE queue times. The actual install takes 1 to 2 days.
Hours, parking, and logistics
MJ Solar Power operates by appointment only and does not maintain a public showroom. Consultations are typically scheduled on weekdays between 9 a.m. and 4 p.m., though weekend appointments can be arranged. Confirm current hours and availability by phone before scheduling, as appointment capacity varies seasonally.
The company serves Baltimore City and Baltimore County exclusively for same-day travel efficiency; projects in Howard or Anne Arundel counties occasionally accepted but incur a travel surcharge.
A local solar installer that employs its own crews and guarantees system performance without requiring customers to navigate a national platform or lease structure remains a practical choice for Baltimore homeowners committed to a permanent energy investment.
