Summary

Shrugs off wind, weighs forty-two pounds

What it is: two 100 W glass panels hinged into a 200 W briefcase with a kickstand, for Goal Zero Yeti stations
The trade-off: rugged and steady in wind, but very heavy and under typical folding-panel efficiency
Not checked: the temperature coefficient, IP rating and bypass diodes; Goal Zero publishes none
Look elsewhere for: MC4 leads, an adjustable tilt, or a panel to carry on foot

Strengths

Tempered glass and aluminum frame survive rough handling
Stays upright in strong wind
Built-in kickstand needs no extra parts
Folds in half with a protective bag

Drawbacks

Very heavy to carry any distance
Below-typical module efficiency
Kickstand angle cannot be adjusted
High Power Port plug needs an adapter for other stations
No power-output warranty

Description

The Goal Zero Boulder 200 Briefcase (SKU 32409, model 32409 on Goal Zero's declaration of conformity) is two 100 W monocrystalline panels under tempered glass in aluminum frames with corner protection, joined by a hinge so the pair folds shut like a briefcase.

It is rated 200 W, with 21.8 V open-circuit and 18.1 V at maximum power on the product page, and its user guide gives 18 to 23 V open-circuit.

Output runs from a junction box through a 6 ft cable to a High Power Port (HPP) plug, 14 to 22 V at up to 14 A; chaining several needs Goal Zero's 4x HPP combiner cable (SKU 98061). Unfolded it measures 40 x 53.5 x 1.75 in, folded 40 x 26.75 x 3.5 in, and it weighs 42 lb (19 kg).

The box holds the panel with its cord and built-in kickstand and a canvas carrying bag. Goal Zero gives its solar panels a 2-year warranty, and the user guide prints 24 months. Goal Zero also sells it in multiples: two for $1,294.80, three for $1,894.75 and four for $2,474.70.

A single panel sells at $599.95 on goalzero.com.
