The Solar Flex™ panel is aerodynamic and durable - a virtually unbreakable solar battery charger for RVs, boats, trucks, and sleeper cabs. Conforms to almost any surface and is designed to provide a powerful charging solution for batteries. The high-efficiency monocrystalline cells produce more power per square foot than any other flexible panel on the market. An impermeable lamination coats the entire module. The panel can be affixed by adhesive or screws, and grommets are provided for ease of installation. The thin, lightweight module can also be sewn into canvas.
