Description
Photonic Universe ▶ FLPROJBB Series
240W Semi-Flexible Solar Panel
Rear Junction Box Design | Made in Austria | High-Efficiency Monocrystalline
The Photonic Universe 240W Semi-Flexible Solar Panel (SKU: FLPROJBB-240M) is engineered to deliver reliable, free electricity for charging 12V battery systems in off-grid applications. Proudly made in Austria, this high-efficiency monocrystalline solar panel is meticulously designed for boats, caravans, motorhomes, and other vehicles where a discreet, integrated power solution is desired. Its innovative rear junction box ensures a sleek, professional finish, free from visible wiring on the panel surface.
Constructed with robust glass fibre reinforced plastic and featuring a special textured surface, this panel maximises sunlight absorption even in low-light conditions or when sunlight strikes at an oblique angle. Fully waterproof and highly resistant to corrosive salt water, it is an excellent choice for demanding marine environments and permanent outdoor installations.
IMPORTANT NOTE: This solar panel requires an appropriate solar charge controller for safe and efficient 12V battery charging. Direct connection to a battery is not advised.

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.
