Outdoor Gear Lab ran some tests of solar panels: The Best Portable Solar Panels and Chargers of 2019. Goal Zero did not come out all that high in their rankings.

I'm not all that knowledgable on solar panels. I don't always care for Outdoor Gear Lab's methodology and conclusions, however on some things they get it right. I'd be curious to see how Russ's conclusions compare with theirs?

I know some folks with remote cabins, who have extensive solar set ups. Some of them run large items like freezers, etc, but they all seem to supplement their solar power with generators, for times when either demand on the system is high, or solar output is low (like in winter).
