This highly durable semi-flexible solar panel reinforced withanodised aluminium and astrong ETFE surfaceand made frommonocrystalline solar cells. This high efficiency 20W solar panel is perfect for permanent outdoor use to provide free electricity for charging 12V batteries to power various applications, such as in a motorhome, caravan, camper, boat, or for solar lighting systems, off-grid, and back up solar power systems. The panel can also be used to provide direct power supply for applications not sensitive to changes in input voltage / current (e.g. electric motors or pumps) and for various grid-tie applications.

Aluminium reinforcement and strong ETFE coating:

This reinforced semi-flexible solar panel has a unique 7-layer construction, featuring anembedded sheet of anodised aluminiumfully encapsulated within the solar panel. This additional reinforcement offers greater strength and resilience, making this one of the most robust semi-flexible solar panels available on the market.

In addition to the aluminium reinforcement, the surface of this 20W semi-flexible solar panel is made of strongETFE material which has a longer service life compared to standard semi-flexible solar panels. As a result, these particular semi-flexible solar panels areextremely hard-wearingand less prone to cracking , delamination and corrosion. The lightly textured coating of this panel creates ananti-reflective surface which allows the panel to absorb a far greater amount of light, thereby increasing efficiency. ETFE material has long been used in applications where durability and high-temperature resistance is required, such as in the Eden Project, Cornwall. You can read more about ETFE and its benefitshere.

Other benefits:

  • Semi-flexible design makes it ideal for slightly curved roofs and surfaces where bonding is preferable (though the panel can also be fixed by bolts or screws)
  • The panel is incredibly light (only 1.1kg) which is great for all vehicles
  • High resistance to salt water environments and possibility to walk on the panel make it perfect for boats and yachts.
  • Sealed waterproof design ensures the panel can be used in all weather conditions.

The panel is fitted with 2 x 0.9m of cable specially designed for solar panels to carry high currents with negligible power loss (2.5mm² cross section). The cable comes with waterproof MC4 connectors which can be used for easy connectivity to your existing system, for linking several panels together or for connecting2.5mm extension cable.
