Highly durable 7-layer construction reinforced with an embedded sheet of anodised aluminium for added strength Surface made of robust ETFE material which has a longer service life compared to standard semi-flexible solar panels. It is less prone to cracking, delamination and corrosion. The lightly textured coating creates an anti-reflective surface which allows the panel to absorb a far greater amount of light Suitable for many applications, such as charging batteries in vehicles and boats, off-grid household solar systems, solar lighting and grid-tie solar systems. Flexible design is perfect for slightly curved surfaces - it can be bonded to any surface without drilling (screwing, velcro and zip mechanisms can also be used) It is possible to walk on the solar panel which is great for boats with limited space on the deck. The panel is incredibly light - only 3.10kg, and very thin - just 4mm, which is ideal for motorhome and caravan roofs.
