  • Keep your fleet running smoothly with the 50W SemiFlex Solar Panel, designed for commercial transportation. This maintenance-free solution charges starting batteries for two battery vehicles, supports TRU batteries, and powers telematics, helping fleet managers prevent starting battery failures, reduce downtime, and lower operating costs.

     

    The Integrated PowerBoost Charge Controller maximizes solar output for 12V battery systems—extending battery life, preventing overcharging, and reducing maintenance expenses.


    The Place & Pull double-release liner enables quick, damage-free installation by minimizing panel flex, a common issue with other semi-flexible designs. This protects the high-efficiency Maxeon monocrystalline cells, ensuring exceptional power output and long-term durability.

     

    With an integrated edge seal, the panel eliminates external edge taping, reducing installation time while ensuring a clean, professional finish that withstands harsh conditions.

     

    The 50W SemiFlex Solar Panel helps fleets stay on schedule by reducing jumpstarts, extending battery life, and cutting maintenance costs—improving reliability, efficiency, and overall performance.
