The solar panel does not hold a charge it produces power when it is exposed to sunlight. Connect it to recharge a portable power station. The Boulder 50 is best used for recharging Goal Zero Sherpa's and Yetis.


Boulder 50 solar panel works best with all of our small to medium power packs and power stations.


  • Q: Are the Boulder Solar Panels waterproof?
  • A: Yes. The Boulders are designed to withstand the elements, so they’re great for permanent installations. What you’re recharging from the Boulders is what needs your help to stay dry, so keep those power packs and power stations covered up and protected from the dust, rain, and snow.
  • Q: Can I chain a Boulder 50 with older Boulders?
  • A: Depends on the panels. Yes, you can chain the Boulder 50 Solar Panel with other Boulders that have an 8mm input or input connector, like another Boulder 50 or the older Boulder 30, by inserting the 8mm blue-ringed connector of the Boulder 50 into the 8mm input of the other Boulder Solar Panel. When chaining Boulder Solar Panels in configurations over 150W, you’ll need to purchase a combiner cable from Goal Zero. Give our customer solutions center call to determine the right cable for your setup.
  • Q: What can I charge directly from the Boulder Solar Panels?
  • A: All of our Boulder Solar Panels are designed to charge Sherpa Power Packs and Goal Zero Yeti Portable Power Stations. If you’re looking to recharge things like headlamps, phones and other USB devices, check out our foldable Nomad Solar Panels.
  • Q:How long will it take to charge my Goal Zero Yeti from a Boulder Solar Panel?
  • A: That depends on a few factors – how big the Yeti is, how big the Boulder is, how cloudy it is, how hot it is, just to name a few. We’ve created a handy calculator that takes all of these factors into consideration. Also, great news, all the Yetis allow for something called “pass-through power”, this means you can be trickle charging your Yeti and using it to power your gear, all at the same time.
  • Q: Can I mount the Boulder Solar Panels to my roof?
  • A: Sure can. We designed the new Boulders to work with traditional z brackets so they’re easier to install. Pairing a Boulder Solar Panel and Goal Zero Yeti Portable Power Station for a camper or van? Talk about a match made in heaven.
