Top 5 Goal Zero Boulder 100 Watt Solar Panel Reviews

1. Love this Goal Zero Boulder 100

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.

2. Quick Charging – Goal Zero Boulder 100

We installed the GZ Boulder 100W panel on top of our truck to charge our GZ Yeti 400 Lithium. Let me tell you that it worked perfectly. Each nigh camping we only dropped the GZ Yeti to 64% and the GZ Boulder 100 charged it up while driving during the day to our next camp spot (usually by lunch). We were traveling in Colorado, New Mexico, Arizona, Nevada, and Utah with mostly clear days in October but even during cloudy mornings the panel would still put out enough of a change to top off the GZ Yeti. Very happy with the new GZ Boulder 100W panel. We have had different panel and battery setups over the past 8 years and this combination is by far the best and easiest to install.

3. Solar Alternatives are very cost effective

Im a resident of Puerto Rico. After hurricane Maria we had our gasoline power generator. It was a big expense . We were without electric power for 4 months. We bought 2 panels to use with our 2 Goal Zero solar generators. It arrived fast and service from Amazon to UPS was excellent. You did Great!!!

4. Weather proven and keeps our boat systems up and ready…all weather

We mounted 2 Goal Zero Boulder 100 on our sailboat over the Bimini on the cockpit. Steady 22.7V most of the day, with a drop to 14-16V with heavy cloud cover. Steady 18-22 knot winds, and gusts to 30knots with torrents of rain, and the Boulder 100 system keeps performing superbly. Looking to add another two Boulder 100s to the set for 400w of power support. Incredible platform – reliable, top quality, provides us the power generation confidence for long cruises!

5. Little expensive but worth it

Was pushing about 70w into my Yeti 1000 at 4:15pm in the NorthEast on Sept 10th so I’m pretty impressed. If you’re going to need a bunch of these there are cheaper options. If you need a couple to fill a Yeti for emergencies spend the extra money and get these. The frame and kickstand are very sturdy. The construction is tops notch. Will be ordering another soon.
