This high efficiency, waterproof 250W monocrystalline solar panel is 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.

This particular model features the junction box and cables on the rear side of the panel to create a completely level surface and professional finish after installation. Please note that in order for this panel to be flush mounted, it is necessary to create a recess in the roof/surface on which the panel is to be mounted.

Product features:

  • Special textured surface which significantly reduces the light reflection and improves performance in low light and cloudy conditions
  • Robust construction using plastic reinforced with glass fibre to create a sturdy and durable solar panel that can be walked on
  • Incredibly light (only 5.1kg) and very thin (just 2mm) which is great for motorhome and caravan roofs
  • High resistance to salt water environments and a sealed waterproof design make this solar panel ideal for boats and marine applications
  • Junction box on the back allows for a smooth and level surface, free of trip hazards and unsightly cables
  • 100% made in Austria to the highest European quality standards using Austrian and German components. IEC certified.


The textured surface of this 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 attached to a rigid surface, it is possible to walk on the solar panel in soft shoes (to prevent accidental scratches), which makes it a perfect choice for mounting on a boat deck. 

The solar panel is fitted with 2 x 0.9m cable (4.0mm2 cross section) with waterproof MC4 connectors which can be used for easy connectivity to your existing system, linking several panels together or for connecting 4mm extension cable.

In addition, the solar cells are guaranteed to produce at least 90% of nominal power in 10 years after purchase and at least 80% of nominal power in 25 years after purchase. This warranty is provided by the manufacturer of the solar cells.



This solar panel comes with a detailed instruction manual which explains wiring and operations. You can download the manual in the Documents tab.

If you are planning to use this panel for charging a 12V battery, it will require a 20A MPPT solar charge controller. To view the full range of MPPT solar charge controllers we offer please visit the Solar Charge Controllers category of our online shop. Note that with a standard non-MPPT (PWM) solar charge controller in a 12V system, the efficiency of charging will reduce significantly. Standard PWM solar charge controllers can only be used with this system when the battery voltage is 24V.

Fitting: This flexible solar panel is normally fitted to a roof using a suitable sealant / adhesive (not included). This panel is designed to be flush mounted and therefore requires a recess in the mounting surface in order to fit the rear junction box.
