Goal Zero Boulder 50 Watt Monocrystalline Solar Panel

This Boulder 50 is a great size for home or on the road charging of our Yeti 200x or a larger unit. Simply set it up in the backyard in direct sunlight and it will charge a well discharged unit in just a few hours and set it back to 100% for charging various devices we all own. Haven't used it yet out camping but it clearly works wherever the sun shines. Can't wait to use it on the road to avoid having to be connected to 110 volts or using our generator. No brainer to use sun power over any other source.

Altogether I bought the goal zero boulder 50 watt solar panel and a yeti 150 solar generator. Everything I need built in, no "Oh no I need more cords" moment. I am in love... I'm homeless, and I play electric cello, so it's complicated. This is a fantastic little setup, I highly suggest it. Electric cello alone, busking time I could power just my 15 watt amp from my generator's 80 watt max output, all day and all night straight. Powers just me and my handheld tech with some practice time on cello for around 4 days without charge, and I don't feel like I'm waiting forever for my generator to charge in the sun. Generator charges both solar and by plugging it into a wall. Boulder 50 + Yeti 150... pure gold. I'm a 5'5" lady, and travel a fair amount of stuff with me. The size makes a difference, and for the weight, this is ideal. ☆☆☆☆☆

Used it for the second time since getting it... This time, to keep my CPAP, cable modem, and phones charged up during a 48 hour power outage. While not recommended for most CPAP devices, my particular machine, the Philips DreamStation, runs off 12 volt power and has a RespLabs Journey backup battery that I ordered around the same time that I ordered this. This solar panel works VERY well with the Yeti and Journey combo. In addition, I was able to maintain internet access even when others were down by running my cable modem off the Yeti, and while the panel does take a while to recharge the Yeti, it works. I highly recommend this combo to anyone needing to power small devices off grid. It's expensive and worth every penny.

I successfully completed a 3 day camping with this along with a Goal Zero Yeti 150. I was able to top off the Yeti from 60% to 100% within 3 hours. This is with it in direct sunlight and 10% cloud coverage and ambient temperature of around 90degrees F. I'm not sure how much of the temperature impacts the performance but I thought it would be worth noting. The build quality is solid and has a fair amount of weight on it. While the price is a bit steep, its worth it for its convenience and build quality.

First time purchasing solar equipment and decided to spring for a well established brand name. The cost is higher than comparable solar panels so I only gave it 4 stars. The panel is exceptionally well built. The tolerances are tight and the aluminum frame is beefy. The panel is a bit heavier than you would expect. I bought the Boulder 50 to pair with a Yeti 200x. I wanted the solid panel because I plan on setting it up next to an overlanding vehicle while camping and would prefer a more solid panel than the foldable panels. The battery pack will power a phone, tablet, laptop, and some Goal Zero led lights. This panel should be able to give me close to a full charge on a sunny day. I like the ability to chain multiple solar panels seamlessly so I can upgrade to a larger battery pack (maybe a Yeti 500x) and simply add another Boulder 50 and have multiple set ups depending on need. I would recommend this to anyone who is willing to spend a little extra for a solid solar panel with a proven track record of dependability.

The Boulder 50 works really well with the Goal Zero 200x to meet our camping needs for running lights at night in addition to keeping cell phones and tablets charged.

Thank god for goal zero. Charge time of my Goal Zero Yeti 150 4 hrs from out the box. Give them your money. You won't regret it. Plus always have a backup plan my dudes. Lets see I use this camping, car camping, at the lake, at the beach. You do need a Goal Zero product to work in tandem. Works well. Ease of use.

This panel was great on our BSA summer Camp. Kept everyone charged and even my goal zero battery back up. Perfect for what we needed. Fast charging just big and not real mobile

発電量もよくスムーズに充電ができていいですね。

It works well and very easy to figure out with the color coded connection cables.

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.

Schnelle Lieferung! Das Solarpanel wir gut verpackt geliefert. Das Aufladen meiner Goalzero 150 funktioniert problemlos auch bei Bewölkung. Es verlängert lediglich die Ladezeit. Das Produkt hat sich in der Praxis bewährt. Einziges Manko ist das Gewicht und die Maße.

fonctionne tres bien
