This reinforcement is fully encapsulated within the panel, providing exceptional strength and resilience, making it highly resistant to physical stress and environmental wear. The panel's surface is made from a robust ETFE (Ethylene Tetrafluoroethylene) material. ETFE is renowned for its durability, high-temperature resistance, and superior lifespan compared to standard PET surfaces. This material significantly reduces the likelihood of cracking, delamination, and corrosion, ensuring long-term performance. The lightly textured ETFE coating also acts as an anti-reflective surface, allowing the panel to absorb more sunlight and thereby increasing its overall efficiency. Utilising high-efficiency monocrystalline solar cells, the panel is designed to convert sunlight into electricity effectively. It comes equipped with 0.9m of high-quality 2.5mm² solar cable, pre-fitted with waterproof MC4 connectors, facilitating easy and secure integration into your existing solar power system or for linking multiple panels. Typical Applications Application Description Motorhomes & Caravans Provides reliable 12V battery charging for on-the-go power needs. Campers & Boats Lightweight and saltwater-resistant, ideal for marine and recreational vehicles. Off-Grid Systems Suitable for small cabins, sheds, or remote monitoring equipment. Solar Lighting Systems Powers outdoor lighting setups where mains electricity is unavailable. Backup Power Contributes to small-scale backup power solutions for essential 12V loads. Direct DC Loads Can directly power applications not sensitive to voltage/current changes, such as small electric motors or pumps. Built-In Protection & Durability The Photonic Universe 20W semi-flexible solar panel is engineered for exceptional durability and long-term performance. Its unique 7-layer construction with embedded anodised aluminium provides significant structural integrity, making it highly resistant to mechanical stress. The advanced ETFE surface coating offers superior resistance to UV degradation, extreme temperatures, saltwater, and chemical corrosion, ensuring a longer operational lifespan. This robust design also makes the panel less prone to cracking and delamination, and capable of withstanding occasional foot traffic, making it particularly suitable for demanding environments like marine applications. The fully sealed, waterproof design ensures reliable operation in all weather conditions. Common Questions Do I need a solar charge controller with this panel? Yes, a solar charge controller is essential for safely charging 12V batteries. It prevents overcharging and deep discharging, protecting your battery and optimising its lifespan. The panel cannot be connected directly to a battery. Can this panel be walked on? Yes, thanks to its reinforced design and durable ETFE coating, this panel is robust enough to withstand occasional foot traffic, making it suitable for boat decks and other accessible surfaces. What are MC4 connectors? MC4 connectors are industry-standard, waterproof connectors designed for solar panels. They ensure a secure and reliable connection, simplifying the process of linking multiple panels or connecting to your charge controller and system cabling. Is this panel suitable for marine environments? Absolutely. The panel's durable ETFE coating provides high resistance to saltwater environments, making it an excellent choice for boats, yachts, and other marine applications. Installation Notes Ensure the panel is connected to an appropriate solar charge controller when charging 12V batteries. Review the manufacturer's handling and installation guidelines before mounting the panel. For optimal performance and longevity, ensure the mounting surface is clean and suitable for bonding if not using mechanical fixings. Consider the panel's semi-flexible nature for installation on slightly curved roofs or surfaces. Proper cable management and waterproof sealing of connections are crucial for outdoor longevity. Before You Buy Verify your system voltage is compatible with a 12V solar panel and charge controller. Confirm the physical dimensions (450 x 350 x 4 mm) are suitable for your intended mounting location. Ensure you have a compatible solar charge controller for your battery type and capacity. Consider your average daily power requirements to determine if 20W is sufficient for your application. For complex installations or grid-tie applications, professional advice is recommended. Please verify all specifications and compatibility requirements with your existing system components before purchase. Product appearance and specifications are subject to change by the manufacturer.
