This high-efficiency, waterproof 250W monocrystalline solar panel is the one of the largest semi-flexible solar panels available on the UK market. It is perfect for permanent outdoor use to provide free electricity for charging 12V or 24V batteries to power various applications. The panel is ideal for flat or curved roofs, such as on boats, caravans, motorhomes, RVs etc as it can easily fit to the shape of the roof when mounted. It is normally fitted to a roof using an adhesive (not included), but it can also be secured with self-tapping screws, tenax fasteners and even zipping.

Product features:

  • Special textured surface significantly reduces light reflection and improves performance in low light and cloudy conditions
  • Robust construction using plastic reinforced with glass fibre creates a sturdy and durable solar panel that can be walked on
  • Incredibly light (only 5.27kg) and very thin (just 2mm) which is great for motorhome and caravan roofs
  • High resistance to salt water environments and the sealed waterproof design make this solar panel perfect for boats and marine applications
  • 100% made in Austria to the highest European quality standards using Austrian and German components. IEC certified.


The textured surface of this solar panel reduces the reflection of light whilst maximising the absorption of light from every possible angle. This ensures high performance in low light or cloudy conditions, or when the light falls at an angle (in the morning, evening or winter).


The fibreglass plastic used in this solar panel is very strong and durable. When the solar panel is mounted on to a rigid surface, it is possible to walk on the solar panel in soft shoes (to prevent accidental scratches), which makes it the perfect choice for mounting on a boat deck.
