not bad, but expenisve

Goal Zero products are expensive. You can buy a 100w solar panel for much less than this; see Renology as an example. Have one of their panels and its great, and with the special adapter from Goal Zero it plugs right into my Yeti for charging. So why this one? A number of different reasons; have two yeti's, so can now charge each one at the same time, instead of one at a time. This has a very serious frame and protection for the panels. The connector is specific for hooking up to the Goal Zero products, so you can really use it with anything else - which needs to be considered. the wire is long enough that you keep your device in the shade with the panel in the sun. And the quality of the build is the reason I bought it. They do a seriously good job on building quality items. Let me rephrase that; these are all built in China, but designed at their place in Utah and their quality control is excellent as is their service. AM NOT IMPRESSED WITH THE STAND. It really only allows this to be propped fully open or keep it closed. Was hoping for something that would be more adjustable for keeping optimum angle of the panel to the sun. and it is for that it loses a star. The Renology panel will ultimately go with my camper as it is lighter weight and will be easier to mount on and off the roof. This will stay at home.

Great solar panel for any Goal Zero power station
by Chuck T (5 out of 5 stars)

I successfully completed a 3 day camping with this along with a Goal Zero Yeti 150. I was able to top off the Yeti from 60% to 100% within 3 hours. This is with it in direct sunlight and 10% cloud coverage and ambient temperature of around 90degrees F. I'm not sure how much of the temperature impacts the performance but I thought it would be worth noting. The build quality is solid and has a fair amount of weight on it. While the price is a bit steep, its worth it for its convenience and build quality.

Yep, works great to keep my ARB fridge chilled. Using with Goal Zero Yeti 400. Tested solar panel this week while at work. Put it on roof of my truck and got a max of 34watts!! Kept up w fridge and even charged the Yeti. I have full confidence it will keep me running the fridge indefinitely. The fridge is the only reason I bought the panel, I don't plan on putting more strain on it by using additional devices. Will add review after 3wk Utah trip 9/17!

In moderately good sunlight, this panel system put out about 55 watts, almost as much as the AC charger provides to the Yeti 1000. So, on a winter day with low-elevation sunlight, it was able to recharge the Yeti at a rapid pace. I kept the plastic bag and styrofoam packing boards and put them into the handy carrying bag to protect the solar panels from bumps and dings, since the solar cells are facing outwards when it is folded up.

Love it.

I love all of Goal Zero products. I have the older Boulder 90, and now I've added this Boulder 100 to the mix. I purchased the Boulder 100 because the Yeti 1000 that I own charges quicker when I use two solar panels. I don't chain them, I plug each one into a separate input port. It's great that the Yeti 1000 has multiple ways to charge it. My Boulder 90 is mounted permanently. This Boulder 100 can move around outside to take advantage of multiple angles throughout the day. I like its portability, but it is a bit heavy. I'm thinking of purchasing the Boulder 50 for added portability, though it's not as powerful. I have my system because I live in northern New England where the electricity goes out about 5 or 6 times a year, sometimes for days at a time. Since I move the Boulder 100 around in the yard I purchased the 8.0MM INPUT 30FT EXTENSION CABLE. I found that I needed the cable right away, so I wish I had bought it at the same time as the Boulder 100. You can call the Goal Zero folks on the phone Monday through Friday with questions, or ask them online during their hours of operation. They are very helpful. I can only say great things about the company. I think the products are expensive, but I've found that they are worth the money. I also try to purchase open box products from their website because it's cheaper that way.

Really nice build quality, good value
by Todd P. (5 out of 5 stars)

People complain that Goal Zero panels are a ripoff but if you look around at other comparable options they are are actually less money than the Renogy folding panels. Monocrystalline high quality panels, beefy aluminum case with reinforces corners, nice carry handle, beefy legs, waterproof connector box all add up to a solid panel. It's not super light but the folding size makes them easy to wrangle and transport. Plugged into the MPPT input on my Yeti 1000, I was able to get up to 70 watts from this in November (I think 80 watts is closer to the best you can expect). Avoid being lulled into getting flexible panels - they will fail quickly while these rigid panels should work fine for 3-40+ years.

A few cons:
- carrying case is just a flimsy sheath that doesn't fully unzip, panels are on the outside so be careful
- kickstand has a fixed 45 degree tilt but in New England, we need closer to 60 degrees in winter so adjustable would be better (placing yoga blocks under each foot is a quick fix)
- uses the GZ 8mm cable which is a pro if you have a GZ Yeti because these are waterproof and solid connections but you need to buy adaptors if you're using a different battery setup
- cables are short, you'll likely need the 15 foot extension cables

This panel did exactly what I wanted it to do. I was able to charge my Yeti 150 from 20% to 100% in 4 hours of morning sun.

A lot of power that's easy to bring with you
by Rachel E. Ciancio (5 out of 5 stars)
September 12, 2017

So far I am very impressed with this panel. Very well built (as is all my GoalZero equipment), comes with a built in handle and a carrying case so it's easy to transport and setup. When I tested it out I was getting 74 watts from the panel, (I am very happy with those numbers as this was around 7pm in Oklahoma with some high altitude clouds). The kickstand is a great addition, I don't have to find something to prop the panels on like I do with my older Boulder panels. It would be nice if it has a little more adjustment but still very helpful. The only thing that would make it better would be to have the "input" port for chaining like the other Boulder panels have (not a big enough issue to cost it a star so I still give it a a solid 5 stars)

Work well, easy to pair, and solidly built

I just used two of these briefcase units (2x100w) at Burning Man and they worked great. I put them on top of the trailer and really didn't bother to turn them toward the morning and evening sun. During the day they got to a high of about 150W generated (combined) which was about perfect for the Yeti 1400 battery we also bought, when combined with my plugging in the yeti battery when the trailer's generator was on. I might add a 3rd unit in the future, but for now two was just fine.

While I did bungee them to the roof of the trailer, they are pretty heavy and I wasn't too worried about any issues with wind. That said, given their weight, I really wouldn't want to have a single 200W unit.

More specifically on the 2x100W vs. 1x200W, I'm really glad I bought two 100W briefcase units instead of one 200W unit. The two units fit perfectly on top of each other on the Frontrunner Outfitters shelf in the back of my Jeep wrangler. I just put a towel between the bottom unit and the shelf and then a towel between the first unit and the second unit and then strapped them down with two 48" flat bungee cords. The towels were probably overkill but given the solar panels face outwards (exposed) when the briefcase is closed I wanted to be safer than sorry. Also, the towels helped the units to not slide on the shelf. The size was also perfect in that I had room to the left of the two panels on the shelf to put the battery. Perfect fit. In addition to a single 200w unit being probably too big for my purposes, these units are not light and I wouldn't really want to haul a single 200W unit onto the top of my trailer.

One note on pairing panels: You can't plug one set of panels into another set and then to your battery. I plugged the two sets of panels into one Goal Zero 4x 8mm combiner to Anderson adapter and then ran a single Anderson power line into the trailer.

Could be better
by Lee Rock (3 out of 5 stars)

I bought this to recharge a Goal Zero Yeti 1000, and although it works, there are a couple of significant drawbacks. The legs are fixed in size, and have no locking mechanism. You basically only have one position available to you, if that isn't what you want....tough. For charging, I found the system to be wildly inconsistent. It will charge, but for no particular reason, the input will drop to zero, then I have to "reset" it, to get it to start charging again. I would expect it to be a plug and forget system, but found I spent a significant amount of time having to ensure it was charging, and doing minor adjustments to the position of the panel to get peak charge out of it. The case it comes in is nice, but not designed for easy on and off, I found it works best with 2 people. It is HEAVY, if you have back problems, be warned.
