Robust construction using plastic reinforced with glass fibre creates a sturdy and durable solar panel. Its surface is made of robust ETFE material which has a longer service life compared to standard semi-flexible panels (less prone to cracking, delamination and corrosion) This panel features 9-busbar solar cells, which makes it efficient and ideal for applications where space is limited. The lightly textured coating reduces light reflection and improves performance in low light and cloudy conditions Highly flexible design makes this panel ideal for curved roofs and surfaces where bonding is preferable (though the panel can also be fixed by bolts or screws) High resistance to salt water environments and sealed waterproof design make it perfect for boats and marine applications The panel is incredibly light - only 3.65kg, and very thin - just 2mm, which is ideal for motorhome and caravan roofs.
