    Explore Efficiency and Power with the 300W Monocrystalline Fibreglass Semi-Flexible Solar Panel

    Are you considering a lightweight semi-flexible solar panel for your caravan, motorhome, RV, boat, yacht, home, farm, or garden office? Your search ends here. These solar panels offer reliability, efficiency, and cost-effectiveness with an appealing payback period, suitable for both flat and curved roofs of stationary domestic, industrial, and commercial buildings, as well as carports, hangars, farms, garden offices, and similar metal rooftops.

    Features:

    • 100% MADE IN AUSTRIA: Crafted to the highest European quality standards using top-notch Austrian and German components. IEC certified for unwavering reliability.

    • UPGRADED FOR MORE POWER: The textured surface of this solar panel reduces light reflection while maximizing light absorption from every possible angle. This ensures high performance in low light or cloudy conditions, or when the light falls at an angle (morning, evening, or winter). The solar panel is equipped with a 2 x 0.9m cable (4.0mm2 cross-section) featuring waterproof MC4 connectors for easy connectivity within your existing system or when linking several panels together.

    • DURABLE, DUST & WATER RESISTANT: Meticulously designed in plastic reinforced with glass fibre, creating a sturdy and durable solar panel. The fibreglass plastic used is exceptionally robust and durable. Soft and sealed edges of the solar panel enhance resilience to mechanical impact on the sides, preventing long-term delamination. High resistance to saltwater environments and the sealed waterproof design make this solar panel perfect for boats and marine applications.

    • SUPERIOR WARRANTY: Backed by a 5-year workmanship warranty covering material and production defects, providing peace of mind.

    • FREE TWO WORKING DAY SHIPPING: If ordered by 5 PM on a working day (delivery times may vary to the Scottish Highlands, Islands, and Northern Ireland).

    Maximum Bending Guidelines:

    • The bending allowed is up to the minimum bending radius of 2000 mm. Modules should only be bent lengthwise; avoid bending them widthwise. In practice, the requirement to have a minimum bending radius of 2m translates into a specific maximum arch height when measured against a straight horizontal line.

    • The maximum height of the arch of a bent solar module will depend on the length of the module. Examples:

      • 50 cm - 16 mm;
      • 80 cm - 40 mm;
      • 100 cm - 62 mm;
      • 120 cm - 89 mm;
      • 140 cm - 121 mm;
      • 150 cm - 139 mm;
      • 170 cm - 178 mm;
      • 200 cm - 245 mm.
    • Excessive or multiple bending must be avoided when handling the modules. The minimum bending radius mentioned above is only for the purpose of mounting permanently on a curved surface. The modules are not designed to withstand such a maximum bending radius for applications where this bending occurs periodically.

    • Important! The curvature of the module must be distributed uniformly across the entire length of the module. Sharp bending may cause permanent damage to the solar cells.

    Installation Guidelines:

    Warning!

    Follow the installation instructions meticulously. Any work on solar modules, including wiring, must adhere to general safety standards in conjunction with these installation instructions. Always entrust such tasks to a duly qualified professional. Energian and Photonic Universe disclaim responsibility for any issues arising from inappropriate installation or product use. In addition to the Photonic Universe installation instructions, it is advisable to adhere to the guidelines outlined in the BS IEC 62548:2016 "Photovoltaic (PV) arrays — Design requirements" standard.

    Gluing:

    The module can be affixed to the surface using an appropriate sealant/adhesive. We recommend SikaFlex 554 super-strong solar panel adhesive for securing solar panels. This adhesive is optimal for fastening solar panels to motorhomes, boats, or caravans. Suitable surfaces include metals, especially aluminum (including anodized), sheet steel (also phosphate, chromate, and galvanized), primers and lacquers (2K systems), ceramic materials, and plastics. It's suitable for securing marine or semi-flexible solar panels to the deck or wheelhouse of a boat. Sikaflex 554 is entirely resistant to saltwater and can endure the harsh sea conditions. Moreover, Sikaflex solar panel adhesive is designed to withstand the most extreme weather conditions.

    When using a sealant/adhesive, refrain from utilizing the module until the adhesive is dry (typically 24h).

    Before permanent installation, we recommend assessing the module's performance by measuring the open circuit voltage (Voc) and short circuit current (Isc) in bright direct sunlight with no obstructions, and comparing it to the specifications. To achieve readings close to specifications, ensure the sun is high in the clear sky, and the module is facing the sun directly.

    Adhesive Tape Bonding:

    Warning! The double-sided adhesive tape on the module forms a robust immediate bond on most smooth, hard surfaces and does not allow repositioning. Attempting to remove the module, even if partially attached, can cause severe damage to the solar cells.

    To affix the module using the double-sided adhesive tape, follow the Photonic Universe installation instructions. For semi-flexible solar panel installations on pop-top roofs, metal roofs, and smooth surfaces, we recommend using a 3M Mounting Kit.

    Self-Adhesive Panel Installation:

    Self-adhesive solar modules adhere directly to the roof material rather than being mounted on racking, as is the case with traditional rigid solar panels. Installation is straightforward. Begin by preparing the roof with a cleaning agent, then remove the protective plastic from the back, and securely roll the module into place.
