Product Overview
The Goal Zero Boulder 100BC is a high-efficiency, portable solar panel designed to provide reliable power for your outdoor adventures. Featuring a rugged, briefcase-style design, it is built to withstand the elements, making it suitable for both temporary and semi-permanent installations. The panel is equipped with an integrated kickstand, allowing you to easily angle it toward the sun for maximum solar intake.
Getting Started
To begin using your Boulder 100BC, simply unfold the briefcase and deploy the attached kickstand. Locate the 8mm blue-ringed cable on the back of the panel and plug it directly into the INPUT port of your compatible Goal Zero Yeti or Sherpa power station. For the best charging performance, it is recommended to reposition the panel throughout the day to keep it directly facing the sun.
Chaining Panels
The Boulder 100BC can be chained with other Boulder solar panels to increase your total power output. To chain multiple panels, insert the 8mm blue-ringed connector of one panel into the 8mm input port of another compatible Boulder panel. Please note that for configurations exceeding 150W, you will need to purchase a specific combiner cable from Goal Zero to ensure safe and efficient operation. For chaining multiple panels using Anderson connectors, a dedicated 4x 8mm Anderson connector cable (SKU 98060) is required.
Safety and Maintenance
While the Boulder 100BC solar panel itself is weather-resistant and designed to withstand dust, rain, and snow, the devices you are charging are not. Always ensure that your power stations, power packs, and connected USB devices are kept in a dry, protected area away from the elements. The panel requires minimal maintenance; simply keep the surface clean from debris and dirt to ensure optimal light absorption. Do not attempt to mount the Boulder 100BC permanently to a fixture, as it is designed for portability and fold-and-go convenience.
Charging Capabilities
The Boulder 100BC is specifically engineered to charge Goal Zero Yeti portable power stations and Sherpa power packs. It is not intended for direct charging of small USB devices like phones or headlamps; for such applications, consider using Goal Zero's foldable Nomad solar panels.
