Goal Zero Boulder 200 review
Goal Zero Boulder 200 Briefcase Solar Panel
By Tom Calder
The Boulder 200 is two 100W glass panels hinged into a briefcase, with a Goal Zero High Power Port output and a stated 21.8V open-circuit voltage. It is built mainly for Goal Zero Yeti stations. At 42 lb it is the heaviest 200W folding panel in this group, and Goal Zero gives no IP rating or efficiency figure.
