Technical Specifications Parameter Value Peak Power (Pmax) 300W Maximum Power Voltage (Vmp) 33.8V Maximum Power Current (Imp) 9A Open Circuit Voltage (Voc) 41.1V Short Circuit Current (Isc) 9.6A Dimensions (L x W x T) 1756 x 1020 x 2 mm Weight 6kg Operating & Power Guidance This 300W semi-flexible solar panel is designed to provide a steady supply of free power for charging 12V or 24V battery banks. It is suitable for permanent outdoor installations where a lightweight, low-profile, and durable solar solution is required. The monocrystalline cells ensure high efficiency, converting sunlight into usable electricity for various off-grid applications. To safely and effectively charge your batteries, this panel requires a solar charge controller/regulator (not included). The controller manages the power flow, preventing overcharging and optimising battery lifespan. It cannot be connected directly to a battery. Typical Applications Application Description Motorhomes & Caravans Ideal for curved or flat roofs, providing discreet and efficient power for leisure batteries. Boats & Marine Vessels High resistance to saltwater and waterproof design makes it perfect for marine environments. Off-Grid Systems Suitable for remote cabins, sheds, or temporary power setups where grid access is unavailable. Specialty Vehicles Can be adapted for various custom vehicle installations requiring flexible and lightweight solar. Built-In Protection & Safety This Photonic Universe solar panel is built for durability and safety, featuring robust glass fibre reinforced plastic construction • a sealed waterproof design • high resistance to saltwater environments • and is IEC certified, ensuring compliance with international safety and performance standards for photovoltaic modules. Common Questions What is the maximum bending radius for this panel? The maximum allowed curvature for this semi-flexible panel is a minimum bending radius of 2000 mm. It should only be bent lengthwise, not widthwise. Can this panel be walked on? While robust, it is generally recommended to avoid walking directly on semi-flexible solar panels to prevent potential damage to the cells or internal wiring, especially if not fully supported underneath. Some similar panels are described as walkable, but for this specific model, caution is advised. Is a charge controller included with the panel? No, a solar charge controller/regulator is not included and is required for safe and efficient charging of your battery bank. The panel cannot be connected directly to a battery. What type of battery can this panel charge? This 300W panel is suitable for charging 12V or 24V battery banks, commonly found in leisure vehicles and off-grid setups. The specific battery type (e.g., lead-acid, AGM, Gel, Lithium) will depend on your chosen charge controller's compatibility. Installation Notes This panel is typically fitted using a suitable sealant or adhesive (not included). It can also be secured with self-tapping screws, tenax fasteners, or zipping. For a flush, professional finish, a recess in the mounting surface is required for the rear junction box and cables. Ensure the mounting surface is clean, dry, and free from grease before installation. Refer to the included detailed instruction manual for wiring and operational guidance. Before You Buy Verify your system voltage (12V or 24V) to ensure compatibility with the panel's output. A solar charge controller is essential for safe battery charging and must be purchased separately. Consider the dimensions (1756 x 1020 x 2 mm) and weight (6kg) for your intended mounting location. Plan for the necessary recess if a flush installation is desired. Ensure you have appropriate mounting materials (adhesive, screws, etc.) for your specific application. Always verify product specifications and compatibility with your existing system components before purchase. This product comes with a 2-year workmanship warranty and a 10/25-year solar cell performance guarantee (90%/80%).
