    Curious About Solar? Start Here.

    Solar economics depend on your utility, electrical load, and system design. Use our calculator as a starting point to explore your potential—no commitments, no guesswork—just clear numbers to help you make an informed decision.

    Explore Solar Potential

    One system. Four jobs.

    A home energy management system is not one product. It is the coordination of solar generation, battery storage, smart load control, and EV charging through properly designed electrical infrastructure.

    Solar produces power

    Solar is the starting point of the system. During the day, your roof produces clean electricity that your home can use in real time before buying power from the utility.

    • Offsets daytime household loads first
    • Reduces utility usage and exposure to rate increases
    • Creates the power source for battery charging and EV charging
    Batteries store excess energy

    Battery storage captures energy that would otherwise be exported, then makes it available at night, during peak utility periods, or when the grid goes down.

    • Stores extra solar production for later
    • Provides backup power during outages
    • Can support whole-home or selected-load backup designs
    Smart panels manage loads

    A smart panel helps the home decide what matters most. It can show circuit-level usage, prioritize essential loads, and help extend battery runtime during an outage.

    • Prioritizes essential circuits when backup power is limited
    • Gives homeowners app-based visibility and control
    • Helps coordinate solar, battery, EV charging, and major loads
    EV charging joins the ecosystem

    Driving on sunshine is the next step in home electrification. A properly designed EV charging setup can work with your solar, battery storage, and available panel capacity.

    • Charges your vehicle from a dedicated Level 2 circuit
    • Can be coordinated with solar production when available
    • Load management helps homes avoid unnecessary service upgrades when appropriate

    The components we design and install.

    BD Electrical & Solar brings the electrical and solar expertise required to make these systems work together safely.

    Solar Production

    Roof-mounted and ground-mounted solar systems designed around your usage, roof, and long-term energy goals.

    Solar is the foundation of the system. It produces clean electricity during the day, offsets utility usage, and creates the power source for battery charging and EV charging.

    Best for: Reducing utility usage, producing daytime power, charging batteries, and supporting EV charging.

    • System sizing based on actual electric usage
    • Roof, shading, service, and future expansion reviewed up front
    • Permitting, utility interconnection, and inspection handled by BD
    • Installed by licensed electricians

    Explore Solar Options

    Battery Storage

    Battery systems that store solar energy for outages, evening use, and greater energy independence.

    Battery storage keeps your home powered when the grid goes down and helps you use more of the energy your solar system produces.

    Best for: Backup power, evening use, self-consumption, time-of-use strategies, and future energy flexibility.

    • Whole-home or partial-home backup options
    • Automatic backup during outages
    • Solar charging during the day
    • Designed around real backup priorities and available capacity

    Smart Panels & Service Upgrades

    Electrical infrastructure that makes the complete energy system work safely and intelligently.

    Your electrical panel is the backbone of the entire system. Solar, batteries, EV chargers, heat pumps, and smart load management all depend on properly designed electrical infrastructure.

    Best for: Circuit-level control, capacity management, battery optimization, and future electrification.

    • 100A to 200A+ service upgrades
    • Solar-ready and EV-ready panel upgrades
    • SPAN Smart Panel installation and configuration
    • Load calculations, permits, inspections, and utility coordination

    Explore Panel Upgrades

    EV Charging

    Home charging designed around your panel capacity, solar production, and daily driving needs.

    Driving on sunshine starts with the right charging setup. A properly designed EV charger can coordinate with solar production, battery storage, and available service capacity.

    Best for: Fast home charging, solar-coordinated charging, and load management for homes with limited service capacity.

    • Level 2 home EV charger installation
    • Dedicated 240V circuits
    • Panel capacity assessment before installation
    • Load management options when a service upgrade is not the best first step
