    One of Florida’s Most Livable Counties Has a Solar Advantage.

    Seminole County consistently ranks among Florida’s most desirable places to live — top-rated schools, established neighborhoods, strong home values, and a quality of life that draws families from across the country. It also has exactly the sun exposure, utility territory, and homeowner demographic that makes solar a smart, long-term financial decision. Castaways Energy brings Orlando-based expertise to every Seminole County installation. We proudly serve these cities:

    Solar & Energy Services Across Seminole County

    Castaways Energy installs rooftop solar systems, battery storage, EV charging, and monitoring solutions for residential properties throughout Seminole County — including Altamonte Springs, Casselberry, Longwood, Winter Springs, Oviedo, Sanford, Lake Mary, and Heathrow. We handle all Seminole County permitting and Duke Energy or FPL interconnection on your behalf.

    Seminole County Solar Incentives & Utility Programs

    Seminole County properties are primarily served by Duke Energy Florida, with some areas served by FPL (Florida Power & Light). Both utilities participate in Florida’s net metering framework. Eligible homeowners also access the 30% federal Investment Tax Credit, Florida’s solar equipment sales tax exemption, and property tax protection. We confirm your specific utility territory and build your personalized incentive and savings picture at your free consultation.

    Solar Financing for Seminole County Homeowners

    We offer $0-down solar loans, battery-inclusive payment plans, lease options, and cash purchase for Seminole County homeowners. Seminole County’s strong and stable home values make solar a particularly sound equity investment — savings on utility bills plus added home value without property tax consequences.
