Measuring 40 x 53.5 x 1.75 inch unfolded, this is the largest of our monocrystalline solar panels. It produces up to 200 watts of power that can be stored in any Goal Zero station, but it is most effective with the Yeti and Sherpa models. It is an easy-to-carry briefcase form makes for the ultimate on-the-go setup. It consists of two panels chained and joined by a hinge, so you can fold them together and carry them by the handle.You can chain the Boulder 200 Briefcase together with other Boulder panels for increased power production. The panel is covered with scratch-resistant tempered glass and is supported by an aluminum frame with extra corner protection, and it features an integrated kickstand that supports it at the optimum angle for charging. The weather-resistant Boulder 200 Briefcase is rugged enough to be permanently installed, but its size, handle and carry bag make it portable enough for car camping, RV use, and other outdoor activities.
