Goal Zero Boulder 100 Briefcase Solar Panel with Cord

2024-09-30T20:00:00

4 stars due to not utilizing the unit yet. Received the package (could use more packaging protection) as the box arrived gouged/torn open from impact but thankfully did not break (as far as I can tell) the panels. Solid construction, I am excited to use the panels with the 1000x unit...time will tell

This panel is well built and the carrying case is a nice touch. Unfortunately the power rating is overstated by at least 25%. Even with the MPPT module, clear day, 75 F, 50 degree sun angle the maximum output is 68 watts. If GoalZero support wants to reach out and let me know how to improve the output, I am open to suggestions. I have the same issue with the 50 watt panel.

I bought this a few months ago, and the charging cable got damaged by wind or animal, so I called Goal Zero today to discuss how to deal with this issue. I spoke to Michael who said they do not sell a replacement cable, and it would be very difficult to repair because it is coaxial - he basically said it was not fixable, and that I would need to buy a new panel. He did not offer any type of remedy like a prefab cable which I believe could be installed in place of the damaged one, nor did he say it was still under warranty. So now I have a perfectly good panel with no way to use it...I can only assume the same applies to their other products with this type of cable as well...so buyer beware!

Originally purchased this unit for a Yeti 500. Best output I've gotten from it (based on Yeti display) is just over 90W. Today, June 7th, at 4pm US/Central in Dallas TX, on a full sun day (no clouds at all) I am getting 71W. BUT, I also recently purchased a Nomad 100 because the Boulder is so heavy. While the Boulder is providing 71W, the Nomad is providing 38W. As I have checked during different conditions, the Nomad seems pegged at a hair over 50% of the output of the Boulder (panels sitting side by side for the comparison). I will probably keep the Nomad as I got it on sale, and it's still something for camping to charge phone, etc, but it doesn't not match the Boulder briefcase. I'm giving it a "Good" rating as the price is a little high of the output, but the build quality is excellent, and the power output matches the rating.

Purchased this to power a new 12v portable fridge. Worked like a champ! Did a trial run and for almost 5-6 hours during my test my Yeti remained at 100% power thanks to the sun and the Boulder. Feels heavier than 25 pounds, but it's heavy duty for sure. Money well spent.

I have been super happy with all of my Goal Zero purchases and was very surprised when I found my Boulder Briefcase shattered after some hail. They have held up to a lot, but not that.

Have used GZ for about 15 yrs. Great products! Recently bought an item that needed a 100 solar panel and instead of ordering theirs for more money, looked to see if GZ might have something...100 panel in open-box. Having had great luck with refurbished items in the past from GZ I ordered. Arrived I a few days. The panel is without any blemish, came with case, even had that new smell. Works great, and was much cheeper!

I bought this to pair with the yeti 500x for an upcoming camping trip. Portability is outstanding and really like the case it came in. I know it states it is 100 watt solar panel but using it I was only able to get 70 watts of power out of it. It really did a great job of recharging the power station and overall happy with the purchase.

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.

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.

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.

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.

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

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.

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

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.

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.

Goal Zero Boulder 100 Briefcase is well made, sturdy, easy to use, compact and not too heavy. Yes, Goal Zero is very proud of their products but they are worth the price. I do have competitive products, so I can actually compare realistically and the Goal Zero Boulder 100 Briefcase is my choice hands down. You can expect, in clear skies, property directed to the sun, to get about 80 Watts out of it, on average in summer. This is a perfect match for Goal Zero's Yeti series "Power Stations" I use this product daily.

The Boulder 100 is rated at 100w, although it barely pulls in 45-55 in direct sunlight on a 70 degree day. If I would have known that was the case I would have just went with the 200.

I added this to go with four Boulder 30's. I have two Yeti 400's chained together, plus two RV batteries. 120 watts for my Yetis and 100 watts for the RV. I only start my generator once a week to circulate the lubricants. I love capturing sunshine!

Actual data plot below shows peak of 70 watts charge at noon 50 miles north of Chicago in February! Enlarge it and read the details of plot; 355 watt-hours of charge in about 6 hours and the angle to sun was not optimal and no tracking. Shadows set in at about 4 pm. I am very pleased with this performance through 60 feet of joined cable. Now, if GZ will just assure me that the Nomad 100 will perform as well and lower its dear cost by 100- 150 dollars, I’ll purchase one of those as a compliment to the boulder bc.

I purchased this last month and it appears to continue to charge my yeti 400 on cloudy days, I am happy that it continues to charge when I use it to run my water generator. Great for those who need portable solar

I have charge the my Sherpa 100 several times in the last week, it made short work on charging it. i have been waiting for the Yeti 1400 to get back in stock. Curious how the Boulder 100 charges it, pretty sure i will have order another Boulder 100 for increase time efficiency.

I have had the Boulder 100 for about a month. I use it to charge a Yeti 400. Very well constructed. My only complaint would be that when folded up, the cells are on the outside rather than inside. The supplied case is nice, but would not prevent damage if it took a sharp strike

Seems to be well-made and performed as expected under limited usage so far. This unit charged my YETI 1400 approx. 35% after 10 hours under a FL summer sun. I faced the panel to the east during the am hours, west during the pm & flat when the sun was overhead. A small quibble is the cable connecting both sides of the panel could be pinched if not careful when folding, unfolding or otherwise manipulating the briefcase.

This came (at last - after the hurricane passed yesterday evening. The box was badly damaged. There is no documentation included. I would have expected to find, at the least, some dta regarding connecting to battery. This leaves a lot of guesswork and uncertainty inthe operation.

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)

Best input only 57 watts in Los Angeles mid-day on a sunny day on two different GZ power stations. 57% is not a passing grade-much less than advertised. (2) Boulder 50s are running about $300 on GZ. The handle is a good idea but the outward facing panels aren't the best design choice. I'm returning mine for the other options.
