The Goal Zero Boulder 200 Briefcase is a rigid 200W solar panel made of two tempered-glass halves in an aluminum frame, with built-in legs. It weighs 42 lb and sells for about $400 to $450.
What you need before you buy
A Goal Zero Yeti, or an adapter for other power stations.
A vehicle or cart to move it; it weighs 42 lb.
A sunny spot to prop it up on its legs.
How much it charges
In good sun, roughly 700Wh to 1,000Wh a day, enough to keep a 1kWh station topped up for an RV, van or outage.
How I researched this: Goal Zero’s Boulder 200 Briefcase product page and specs, the Amazon listing, and a video review from Outdoor Adventure. Prices checked October 30, 2026.
