High Efficiency Monocrystalline Cell Technology

The Goal Zero Boulder 100 Briefcase Solar Panel consists of two Boulder 50 solar panels daisy chained and connected by a hinge. The panels use highly efficient monocrystalline silicon cells that can generate up to 100 watts of power when angled correctly toward the sun. The output can be used to charge any of Goal Zero’s Sherpa or Yeti generators when you’re away from AC power.

Folding Design

The Boulder 100 Briefcase comprises of two Boulder 50 Solar Panels chained together and connected by a hinge. When not in use, the two individual panels fold over, offering a smaller footprint for storage and transportation. A built-in handle on the frame ensures easy portability.

Integrated Kickstand

A simple fold-away kick stand helps you maximise its efficiency by allowing you to acheive the optimum angle to the sun. Simply plug the Goal Zero Boulder 100 Briefcase into your Sherpa or Yeti recharger and use the integrated 8mm output cable to begin charging and phones, laptops and more.

Note: The Boulder 100 Briefcase Solar Panel will not charge devices directly. We recommend a Goal Zero Sherpa or Yeti to store store and transfer the power generated by the panel.
