Goal Zero Boulder 100 Briefcase 100W Monocrystalline Solar Panel — Foldable, Rugged

Lightweight but rugged, the Boulder 100 Briefcase combines two 50 W monocrystalline panels inside an anodized aluminum frame and tempered glass to deliver dependable solar power where you need it—camping, job sites, off-grid events, or as backup for home emergencies. Designed by Goal Zero with practical outdoor use in mind, the briefcase folds for transport, includes a built-in kickstand for angle adjustment, and chains with other Boulder panels to expand capacity.

How does the Boulder 100 Briefcase perform in real-world conditions?

This panel is engineered for consistent field performance: monocrystalline cells give higher efficiency per area, tempered glass protects against impacts, and the aluminum frame resists corrosion. Field-tested in diverse climates, it’s intended to hold up through rugged handling and repeated setup.

• 100 W total output from two 50 W panels for steady solar harvest.
• Tempered glass and reinforced corners for improved durability.
• Anodized aluminum frame resists rust and bending on rough terrain.
• Kickstand adjusts angle to maximize sun exposure on-site.

What equipment does it pair with and how easy is it to use?

The Boulder 100 Briefcase is built to work seamlessly with Goal Zero Yeti power stations and other compatible battery systems via standard MC4 or the included cable options. Setup is straightforward: unfold, position with the kickstand, connect to a power station, and chain additional panels if you need more capacity.

• Plugs into Goal Zero Yetis and most solar-compatible power stations.
• Chainable design allows linking multiple Boulder panels for higher wattage.
• Briefcase form factor opens and closes quickly for fast deployment.
• Clear labeling and simple connectors for easy field setup.

How portable and weather resistant is this solar briefcase?

Weighing and sized for transportability, the briefcase format makes hauling and positioning simple for solo trips or team deployments. Built materials—tempered glass and an anodized frame—provide weather resistance and impact protection; however, like most solar gear, it should be sheltered from extreme weather when possible.

• Compact foldable design with integrated carrying handle for mobility.
• Tempered glass shielding to protect cells from debris and scratches.
• Corner protection and robust frame for frequent transport and setup.
• Store upright and dry to prolong the panel’s service life in harsh climates.

What safety and warranty support come with the Boulder 100?

Goal Zero emphasizes safe, reliable construction with user-friendly features and built-in protections to reduce risk during use. The Boulder 100 Briefcase ships with a two-year warranty and is produced to meet practical field standards rather than experimental setups.

• 2-year manufacturer warranty for defects and construction issues.
• Robust physical construction to minimize accidental damage risk.
• Designed for safe chaining and connection with compatible systems.
• Goal Zero’s U.S.-based engineering and field testing support product quality.

Who is this for? The Goal Zero Boulder 100 Briefcase is ideal for campers, van lifers, contractors at remote job sites, event operators, and homeowners who want a rugged, portable solar solution to pair with a battery system. If you need a reliable, field-ready panel that balances portability with professional-grade durability—and the flexibility to expand capacity—this briefcase-style panel is tailored for those practical, on-the-go power needs.
