Overview

The GoalZero Boulder 100 briefcase solar panel is designed to generate reliable, self-sufficient solar power, whether you're hiking, working on a job site or attending an off-grid event. Thanks to its foldable briefcase format and built-in kickstand, it sets up facing the sun in seconds to recharge your Sherpa or Yeti portable power stations. Its rugged tempered glass and aluminium construction makes it a durable companion for regular outdoor use, for individuals and for Swiss professionals on the move alike.

Use and Care

Position the panel perpendicular to the sun's rays using the built-in kickstand to maximise energy production throughout the day. Connect it directly to a compatible Goal Zero portable battery (Sherpa, Yeti) via the 8 mm solar port - no external charge controller is needed for these models. After each use, fold the panel along its hinge and store it in the supplied canvas carry bag to protect it from dust, moisture and impacts during transport or extended storage.
