Specialised Vehicles Suitable for various custom vehicle builds requiring flexible, lightweight, and durable solar power. Built-In Protection & Quality This Photonic Universe solar panel is built for resilience and long-term performance. Its robust glass fibre reinforced plastic construction, combined with intelligently designed soft and sealed edges, enhances resistance to mechanical impact and helps prevent delamination. The panel is fully waterproof and demonstrates high resistance to corrosive salt water, ensuring reliability in challenging environments. Manufactured in Austria to the highest European quality standards using premium Austrian and German components, it holds essential IEC certification, verifying its compliance with international safety and performance benchmarks. Common Questions What kind of surfaces can this panel be mounted on? This semi-flexible solar panel is designed for effortless mounting on a variety of roofs, including flat or gently curved surfaces. It can adapt to the shape of the roof when mounted. How is the rear junction box accommodated during installation? For a perfectly flush and integrated appearance, it is essential to create a small, shallow recess in your mounting surface to properly accommodate the rear junction box and its connected cables. Can I bend the panel significantly? While semi-flexible, these modules are not designed to be rolled up or folded. The maximum allowed curvature is up to a minimum bending radius of 2000 mm, and they should only be bent lengthwise for permanent mounting on a curved surface. Excessive or multiple bending should be avoided. What kind of charge controller do I need? An appropriate solar charge controller is required to regulate the power from the panel to your 12V battery system. For optimal efficiency, especially with higher voltage panels like this 240W model, an MPPT (Maximum Power Point Tracking) charge controller is generally recommended. Installation Notes Mounting options include suitable sealant/adhesive, self-tapping screws, tenax fasteners, or zipping. A recess in the mounting surface is necessary to accommodate the rear junction box for a flush finish. Ensure the mounting surface is clean, dry, and free from grease before applying adhesive. Avoid excessive or multiple bending of the panel; only bend lengthwise for permanent installation on curved surfaces. All wiring should follow general safety standards and be carried out by an appropriately qualified person. Before You Buy Verify the panel's voltage and current specifications are compatible with your existing solar system components. Ensure you have an appropriate solar charge controller for your 12V battery bank. Consider the dimensions and weight for your intended installation location. Plan for the necessary recess to accommodate the rear junction box for a flush mount. Consult with a qualified installer if you are unsure about system design or installation requirements. Always verify product specifications and compatibility with your specific system requirements before purchase. This product includes a 2-year workmanship warranty and a 10-year 90% / 25-year 80% power output warranty on the solar cells.
