TOUGH CELL PROTECTION
LIGHTWEIGHT & COMPACT
LAMINATED TEXTILE COVER
MC4 CONNECTORS
WATERPROOF
PORTABLE SOLAR PANEL DESIGNED FOR TOUGH ADVENTURES
The new Tough Fold series are the most durable and most portable solar panels you could ever wish for. As a part of the Tough family, the Fold has inherited the same sturdy cell cover. The laminated textile outside, combined with the soft edges and stiff center core, offers an exquisite and functional solar panel.
The laminated one-piece design results in a completely waterproof solution, greatly improving life expectancy. When unfolded, the size is remarkably small thanks to highly efficient solar cells. The folded size is extremely small in all dimensions thanks to the one-piece construction and the extremely flat junction box.
For full compatibility with industry-standard solar panel equipment the panel utilizes waterproof MC4 connectors. Connection and disconnection are made easy by the extra finger-friendly construction of the connectors. We recommend using the 41W and 62W models in combination with the incredibly small Mini-R solar charge controller.
