A tough glass-and-aluminum 200 W panel for RV, van and base-camp use where it stays put. If you need to carry it any distance, a fabric folding panel weighs half as much.

Pros
  • Tempered glass and an aluminum frame survive rough handling far better than fabric panels
  • Delivered 83% of its rating in an independent side-by-side test
  • Plugs straight into a Goal Zero Yeti and comes with a canvas carry bag
Cons
  • At 42 lb it is a two-hand carry and too heavy to move often
  • HPP connector needs an adapter for most non-Goal Zero stations

How it scores

The rating comes from 6 measured or published factors, each scored 0-100 against fixed reference points for its size. How we rank explains each one.

Independent output tests

The most power independent reviewers measured from the panel in real sun. Heat, haze, sun angle and the device being charged all cut output, so 70-85% of the rated watts is a normal real-world result.
