Use the sun to power up your gear with the Goal Zero Boulder 50 Watt Solar Panel. Made from strong tempered glass, this eco-friendly gadget features an aluminum frame with extra corner protection. Additionally, the Boulder 50 is ideal for permanent or temporary installation. It comes with a built-in kickstand, allowing you to set it at the ideal angle to the sun. The Boulder 50 doesn’t hold a charge, enabling it to produce power solely when it has sun exposure. However, you can use it with a portable power station or portable power back to charge your devices at any time of day. The solar panel is ideal for recharging Goal Zero Yetis and Sherpa’s. Likewise, it works well with any of Goal Zero’s small to medium power station and power packs.
