Boulder 100 Briefcase, 100 Watt Monocrystalline Solar Panel | Connected 50W Panel Pair, Tempered Glass & Aluminum Frame, Hinged Design with Canvas Carry Bag

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 30-40+ 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 - I recommend combining 8mm panels into the Anderson connector because that extension cable uses high gauge wire - expect big losses with the 8mm extension cables

Goal Zero never disappoints. I have several of their products and this charger did not disappoint. Very rugged, but slightly heavy, to be expected given the quality of the unit. Easy to setup and use.

I buy these for the smaller size and lower weight. I am able to move them around easily and pack them away after use. I have several and all work well, even the refurbished one I bought directly from Goal Zero. Even if you are stronger than me, you may find the compact size useful. They do cost quite a bit, but I feel they are a good value and the company has very good customer support should you need to contact them. Since we went to solar power our camping is much more quiet and pleasant and I don’t have to fire up the generator in the morning while others sleep. Also, they can charge when clouds cover the sun. Slow and low, but still powering through light clouds..

I'm a novice to solar but so far my opinions of it aren't so bad, especially with this system. I bought a 400w Goal Zero Lithium because I couldn't find a 1000w & the 1400w was too pricey. I'm a truck driver & I have lots of down time. I thought that buying a small system like this would prevent me from running my engine & substitute for an APU. When I'm driving my truck I can charge the 400w with my inverter using the truck alternator to generate the power and at night I can use the 400 w to power anything I need electrically. It saves lots of fuel and money. I thought that by buying the solar panels I would be able to put them up in the front windows of my truck and collect light but I was sadly mistaken. If you are thinking about buying solar panels, know this and be warned, solar panels take direct sunlight to charge the unit. When I first took these out of the box I was disconcerted about the weight because they were pretty heavy and I was expecting something, not really flimsy, but lighter. They are solidly built and if you take care of them, respect them and do not drop them, they will last you a long time. On the very first day, out of the box, I had good sunlight and figure it out immediately by the lack of charging I was getting from my initial position that I had to put them in direct sunlight. When I did I got 70 watts of power powering them. I was getting about a 9% charge every 30 minutes which is excellent. That is absolutely free energy and you can take that with you anywhere you go, as long as you got direct sunlight. When the clouds came in front of the sun I only got about 19 to 20%. I gave this product five stars for value and weatherproof but only three stars for easiness of use. Solar power and solar panels are not easy to use. I think the word inconvenience comes to mind more often than I wished. I'm sitting here babysitting the panels and my battery because I don't want them to be stolen. But I can't keep them secure and get direct sunlight at the same time. Granted most of the time I will be charging this battery the old-fashioned way with an alternator but solar panels are a nice alternative. They do give you options. Just be prepared for the inconvenience.

Great Solar panels for camping to charge up our portable generator. Great value for what you paid for. Cord length is great, easily portable and easy to carry.

These panels work just as described. I have the Yeti 1250 and they hook up easy and store nicely in the provided case. In Tennessee I only get about 75-78 watts on a clear sunny day and normally get about 68-73 watts on a average which I hear is normal for about any panel. I'm sure this would get a few more watts if I lived further south. I have added a second set to my collection.

Bought this to recharge my Goal Zero Yeti 1000. Recharges faster than plugging into a wall outlet. PG&E turns off power to our local area during high wind events and our propane/gas generator, although reliable, is super noisy for us and the neighbors, especially when running through the night. this allows me to run the YETI during the day while simultaneously recharging for free. Included suitcase to protect during relocation or transporting. if you have an RV or camp[, this would allow for you to maintain all your modern conveniences. Great build quality, but you have to remember it's glass when moving or storing.

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)

Arrive within 2 days, second to non build quality and top notch performance. Cloudy day, it gave out between 15W to 30W input, really impressed and fully recommended. Way more powerful than my 20W portable panel

Becomes useless when power station dies and will need converter plugs when using in tandem with (most) non-Goal Zero power stations.
