Brunton's drive and desire to pioneer a line of rugged power sources led to the introduction of the first flexible solar panel, the SolarRoll. Since then, the evolution of this concept has flourished. Backed by glowing reviews in every major magazine and newspaper in this country and others, the SolarRoll has officially taken its place as one of Brunton's most talked about products. The proof, though, is in the remarkable performance. The waterproof SolarRoll has given sea kayakers the power to photograph their voyages from the far reaches of the planet. And next spring, it will assist Ed Viesturs in his final summit, Annapurna, as he polishes off the last peak of Endeavor 8000. Ideal for powering satellite phones, members of expeditions worldwide pack the SolarRoll in place of expensive extra batteries that don't offer much relief in the form of weight. Brunton realizes however, that not everyone is defying the ordinary. Some of us simply need the SolarRoll for charging our car battery or running our video camera. With this in mind, Brunton is offering alternative sizes and outputs such as the SolarRoll 4.5 and the SolarRoll 14 to accommodate the growing demand for its most popular solar panel.
