The Xantrex Solar Max 80W, 165W, and 220W flex kits, feature solar panels with a mesh grid-technology that provides superior durability and performance benefits. With approximately 2000 points of contact per cell, this mesh grid-technology allows the panel to flex up to 180 degrees, without impacting power output. Subjected to extreme environmental and accelerated lifecycle testing beyond regulatory standards, the Max panel was tested to be 50 times more durable than a standard flexible panel.
