200 Boulder Solar Panels Rock
I received my solar panels 2 days ago and I just set them up to charge my Yeti 1500. I'm a novice to solar panels, but I received great communication from Goal Zero as to which panels best suited my power station and cabling needed. I got the 15 feet extension cord. Recently we had several outages here in California and I ran my 1500 which powered our fridge, router and CPAP machine for almost 2 days. Now that I got the solar panels at least I'll be able to recharge the 1500 and keep our food from spoiling, internet connectivity and my CPAP Machine.Update: These panels will only charge your Yeti Units, and if you have an appliance connected to the Yeti which output exceeds the input you receive via the panels, you'll have to disconnect the appliance and let the panels charge the Yeti. Otherwise, your Yeti will be depleted before the solar panels begin charging it. Also, I gave it a 4 star rating because of the weight of the panels and the Yeti 1500, quite heavy.Second Update: I continued using the panels for a couple of weeks now and unless you get full son light, the panels will not charge the 1500, a partially cloudy day will yield no charging power from the panels and I came to find out from other reviews that a $100 solar charging optimizer is required to be installed on the $1500. Pretty disappointing having to cough up an additional $100 after spending close to $800 On the panels, plus $1,700 for the Yeti 1500X. The panels have worked pretty good on full on sunlight though, but the optimizer should be standard on the Yeti units.

5.0 out of 5 stars Works great in conjunction with the Goal Zero 1000W Power Station
Reviewed in the United States on April 12, 2022
Bought this mainly for emergency use, but also occasional offgrid needs. First test was to hook it up to the power station and run a RecTeq Bullseye wood pellet smoker/grill. Using the two together, was able to get a net positive charge while running the smoker (in other words, it was charging faster than the smoker was drawing power). This was on a mostly sunny/partly cloudy day, with a little bit of shade on the panel. Granted, the power station and solar panel are brand new, but they seem pretty solid and well built. So far it seems like a good investment. My only constructive criticism so far is I wish the cord from the solar panel to the power station was a couple of feet longer - I'm guessing it's about 4-5 feet, an 8 foot cord would be really handy, but it's not a deal breaker.

Reviewed in the United Kingdom on June 11, 2022
Great solar panel. Very efficient, I’ve gotten around 47w max so far in direct sunlight. Output ranges between 5w-47w depending on conditions. Pairs well with the Sherpa 100ac which charges to full in around just under a day with this panel. Thinking about getting the Yeti 500x to make the most of the panel.
