We tested 100+ watt solar panels from Goal Zero, Jackery, Ecoflow, BigBlue, Renogy, and more to charge your off-grid power station. The right solar panel extends a power station capacity from limited to potentially delivering perpetual power (so long as the sun is out!).

Which solar charger is best for base camping?

The Goal Zero Nomad 50 is a larger solar charger that is our winner for best for base camping. At 50 watts, it's the biggest and heaviest solar charger we tried. Like the Nomad 20, it can be linked to other solar panels and the only one that can be attached in a series to provide even greater charging power to a battery power bank.

Are portable solar chargers a viable way to provide electricity outdoors?

Thanks to efficiency advances and cost decreases in solar cells, portable solar chargers are finally proving to be a viable means of providing electricity outdoors. A backcountry user might carry a smartphone, GoPros, headlamp, tablet, camera, headphones, and PLB or GPS devices.
