Why We Like The Boulder 100 Briefcase
Whether we're escaping society by traveling into the wilderness, road tripping the country in our converted van, or prepping our house for when the grid goes down, the Goal Zero Boulder 100 Briefcase offers us a sturdy, foldable design for convenient travel combined with the ability to harness up to 100 watts of energy directly from the sun.
This foldable solar panel is comprised of two Boulder 50 solar panels attached with a hinge, so you can easily slide it into the provided carrying case before embarking off the grid. The sturdy aluminum frame and Z Brackets compatibility give you the ability to attach this solar panel to the roof of your humble abode, camper, or van. It's also chainable with older Goal Zero Boulder 15/30 Solar Panels, as well as with the Boulder 90 Solar Panel (with the use of an MC4 to 8-millimeter adapter). This allows you to harness even greater energy from the sun, maximizing the energy going into your Goal Zero power pack or portable power station.

Built like a tank
Like all Gold Zero products the Boulder 100 is built with quality in mind. The downside is you have to be a bodybuilder to carry it.

Perfect 100watt panel with a sturdy build.
This solar panel is a no worry, durable panel. I don’t hesitate to throw it out in parking lots and juice up while parked.

Very pleased with the output.
Purchased a Yeti 500X a few months back and decided to get a panel to go with it, mostly for outages. Used the Boulder 100 for the first time today. Cold (10 F) winter day about 10:30am and it was putting out 85 watts. It's sunny but the sun is very low in the sky so I wasn't expecting that amount of power. Very pleased. It's a bit heavy so not taking it backpacking but is very solid and seems well built.

Easy to use
Finally set off on our can life adventure! Found the Boulder briefcase easy to set up and pack away. Seems to charge our Goal Zero generator fairly well. Just have to adjust to the suns angle to get the best charge.

Off-grid life
The perfect set up for our Yeti500 battery bank. Convenient and manageable for a couple living off-grid.

Sturdy, Semi Portable, Short Cord
This is my first solar panel so I don't have much to compare this to. It's very study, dropped it out of the car a few times and kids have tumbled over it. It's fine for car camping and home use but wouldn't want this overlanding or even for a basecamp trek. Cord is very short, I guess to be part of a series of panels on an extension cord to get further from camp.

Easy carry.
Haven't use the panel yet, but my brother says they work great.

boulder 100 briefcase after 2 years
I use a yeti 1400 lithium with MPPT and a pair of boulder 100 briefcase panels primarily to power my small travel trailer off grid camping and at motorcycle trial events. I'm very pleased with the performance of this setup. My experience is that on a clear, sunny day the pair of 100 boulders will charge the yeti at a rate of 90 to 150+ watts/hr. I actually have seen over 180. I highly recommend these products.

Looks good, concern with durability
I bought the Boulder 100 and received it today, yet to test it as it is raining. This is going in my overland vehicle, a '91 Jeep Cherokee to power my Yeti 400. First impressions are that it appears well built, hinges feel sturdy when opening the panels and the handle is comfortable making it easy to lift. My first concern is that the two clamps are quite petite and I would question their durability. The second concern is that the panels when folded have the glass out, and the case does not offer much in the way of protection. To me, this had the potential to easily damage the panel is transported or if knocked over. Will follow up once I get a chance to hook them up to my Yeti and test them fully.

I have the boulder briefcase 100. I'm just wondering if it is waterproof? I typically connect it to my Yeti 1500 (which I know should not be exposed to elements) but can I leave the Boulder out in the rain? Thanks!

Can battery (1400) be in use and charging simultaneously?

Saw an almost answer in the Q&A section... I have a Boulder 50 set up outside, was thinking of plugging my Briefcase 100 into that and connecting the Boulder 50 to my Yeti 200x...I am guessing it might be okay, but any concerns?

How does it perform if there's some shade on the panels? For example, it may start out with full sun but over the course of the day, some shade may hit the panels. Thanks.

How can the cables at the back of the panel be replaced or spliced? My dog chewed through them.
December 18, 2020
What angle range can the panel be adjusted to? Is is a fixed angle of 40 degrees, or can it be adjusted between something like 20 and 50 degrees?

Can I leave my briefcase 200 panel in the case in the camper in the unheated garage over the winter? I usually bring it in the house, but forgot.
