Its ETFE (Ethylene Tetrafluoroethylene) top layer provides a self-healing "memory effect" for minor abrasions and a dimpled, anti-slip surface, making it suitable for high-wear areas like boat decks. The panel's six-layer heavy-duty laminate ensures complete waterproofing and protection of the solar cells, complemented by a unique curved, mechanically fixed junction box with strain relief for the pre-fitted 4m UV stabilised PV cable. The included STCC10 10A dual battery charge controller is designed for off-grid solar systems, offering automatic 12V/24V system voltage recognition. Its primary function is to efficiently charge two battery banks simultaneously using Series PWM technology, optimising battery lifespan and overall system performance. The controller incorporates comprehensive self-diagnostics and electronic protection features to safeguard against installation errors and system faults. Typical Applications Application Description Campervans & Motorhomes Provides auxiliary power for lighting, mobile device charging, and low-power DC appliances. Marine Vessels Maintains leisure battery charge on boats and yachts, resisting sea spray and UV. Off-Grid Cabins & Sheds Supplies power for remote lighting, electric gates, and other low-energy consumption needs. Remote Monitoring Powers small sensors, communication equipment, or security systems in isolated locations. Built-In Protection Functions The STCC10 10A Dual Battery Charge Controller includes comprehensive electronic protection functions to prevent damage and ensure system longevity. These include: Reverse current protection • Overload protection • Open circuit protection • Lightning surge protection • Deep discharge protection • Charge current protection up to 10A. Common Questions What type of batteries can this kit charge? The 10A charge controller is designed for 12V or 24V lead-acid batteries (e.g., sealed, gel, flooded) and can charge two battery banks simultaneously. Is the solar panel truly flexible? Yes, the panel is semi-flexible, allowing it to be bonded to slightly curved surfaces (up to 3cm curve per metre). How is the panel installed? It can be bonded using suitable adhesives (e.g., Simson ISR 70-03) or mechanically fixed via pre-drilled 4.5mm holes. Proper airflow underneath the panel is recommended to prevent heat build-up. What are the benefits of the ETFE surface? The ETFE top layer provides enhanced durability, a self-healing capacity for minor abrasions, and a dimpled, anti-slip surface, making it robust for various applications. Installation Notes Ensure the mounting surface is clean, dry, and suitable for the chosen installation method (bonding or mechanical fixing). Follow manufacturer guidelines for adhesive application to ensure proper airflow beneath the panel, preventing heat build-up and potential warping. Connect the charge controller to the batteries before connecting the solar panel to avoid potential damage. Verify correct polarity for all electrical connections to prevent system faults. Consider cable routing and protection from environmental elements for long-term reliability. Before You Buy Confirm the power requirements of your intended appliances align with the 20W output of this solar panel. Verify your battery type and voltage (12V or 24V) are compatible with the 10A dual battery charge controller. Assess the available mounting surface for size, curvature, and suitability for flexible panel installation. Consider any additional cabling, fuses, and connectors required for a complete and safe installation. Consult a qualified installer if unsure about system design, electrical connections, or specific application requirements. Specifications are based on manufacturer data and are subject to change. Always verify compatibility before purchase. The PV Logic flexible solar panel comes with a two-year product warranty.
