The Goal Zero Boulder 100 Solar Panel has renewed monocrystalline solar cells (A class) and is equipped with standard Goal Zero DC output, 8mm format. Via the Goal Zero 8mm Combiner Cable, the Boulder 100 Solar Panel can be connected in parallel to up to 3 other Boulder 100 Solar Panels for even higher power output.
good for wild camping, and not having permanant solar on roof of van.
Gret product and plug n play to rest of the goal zero range. I mated to 150 and hence charges in spain in a few hours, rather than slower charging off a 20 panel i keep on the vans dash.
