Well Built - Power Rating Overstated

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.

No, I would not recommend this to a friend.

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.

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.

A lot of power that's easy to bring with you.

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)

used it 2x. live it. 3 things I'd change is the clips holding it together are too petite. I'd change the fold design to follow the other way to protect the solar cell from contact and a padded case. maybe change the 8mm cord. I use it on my yeti 400.

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.

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.

Not as much power as advertised

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.
