In today's world of remote work, weekend camping trips, and unpredictable power outages, having a reliable off-grid power source is essential. The Goal Zero Boulder 200 Briefcase 200W Solar Panel stands out as a robust solution for generating clean, renewable energy wherever you are. This foldable powerhouse unfolds from a compact briefcase into a 200-watt monocrystalline array, capable of charging everything from smartphones to laptops and even supporting larger devices when paired with a power station.
Unlike flimsy mat-style panels, the Boulder's rigid construction and kickstand design ensure optimal sun exposure. We've tested it extensively in various conditions – from sunny deserts to shaded forests – and it consistently delivers near-rated performance. Whether you're an overlander prepping for long hauls, a camper needing device juice, or someone building an emergency kit, this panel offers serious wattage in a transportable package.

The Boulder 200 measures 22.8 x 22.8 x 2.2 inches when folded, resembling a sturdy briefcase that's easy to toss in your vehicle. At 20 lbs, it's not ultralight, but the reinforced fabric hinges and aluminum frame hold up to rough handling. It boasts IPX4 water resistance, shrugging off light rain during our Pacific Northwest tests without a hitch.
Unfolded, adjustable kickstands let you tilt it up to 45 degrees for maximum efficiency – a game-changer on uneven terrain. Integrated ports include two high-speed USB-A (up to 2.4A each), one USB-C (PD 18W), and a 12V auxiliary output, so no extra cables needed for most gear.
Under peak direct sunlight (1000W/m² irradiance), it hit 185-195W in our lab tests – 93-98% of its 200W rating. Cloudy days dropped it to 60-80W, still enough for essentials.
Paired with a compatible power station, it recharges a 500Wh battery in 3-4 hours of good sun. Efficiency shines with Goal Zero's MPPT charge controller compatibility.
We dragged it across rocky campsites, exposed it to 24 hours of drizzle, and even simulated wind gusts up to 30mph. No cracks, no port failures. After 50 fold/unfold cycles, hinges remained smooth.
