Jump to the sectionProduct Overview
The Goal Zero Boulder 100BC is a portable, high-efficiency monocrystalline solar panel designed for outdoor power needs. Its briefcase-style, foldable design makes it highly portable, while the integrated kickstand allows for easy angling toward the sun to maximize solar intake. The panel is built to withstand various weather conditions, making it suitable for both permanent and semi-permanent installations.
Getting Started
To begin charging, simply unfold the panel and use the attached kickstand to position it directly toward the sun. Connect the 8mm blue-ringed cable 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 solar panel throughout the day to track the sun's movement.
Chaining Panels
You can increase your power output by chaining multiple Boulder 100BC panels together. For configurations exceeding 150W, you will need to purchase a specific combiner cable from Goal Zero. Please contact customer support to ensure you select the correct cable for your specific setup. When chaining, insert the 8mm blue-ringed connector of one panel into the 8mm input port of another compatible Boulder solar panel.
Safety and Maintenance
While the Boulder 100BC solar panels are weather-resistant and designed to withstand the elements, the devices you are charging (such as power stations or power packs) are not. Always ensure that your connected power stations are kept dry and protected from dust, rain, and snow. The panel itself does not require complex maintenance; simply keep the surface clean from debris to ensure maximum efficiency.
Charging Capabilities
The Boulder 100BC is specifically designed to charge Goal Zero Sherpa power packs and Yeti portable power stations. It is not intended for direct charging of small USB devices like phones or headlamps; for those applications, consider using Goal Zero's foldable Nomad solar panels. The charging time for your power station will vary based on the size of the battery, weather conditions, and temperature.
