According to a 2017 American Camper Report, 74% of campers use a smartphone while camping. Furthermore, many people who use RVs, trailers, cabins and boats now require off-grid power to stay in touch with their loved ones.

But what happens when you run out of juice?

If you’re a camper or adventurer who’s looking to keep your devices powered up, a 100 watt solar panel kit may be the answer. Solar panels allow you to power your devices without relying on outlet power, so they’re perfect for true off-the-grid adventurers.

So, which one should you buy? Here I look at the best 100 watt solar panel kits on the market.

Aside from being quiet, what I like the most about this solar panel 100 watt system is it comes with all the accessories included, so there was little that I needed to purchase separately. If you want a convenient, high-quality system at a good price, then this kit is the way to go.

If you’re looking for a sturdy and reliable 100 watt panel that will supply you with watt hours for decades to come, this is another great kit that's worth your money.

These solar panels are made from extra thick low iron-tempered glass that’s robust and impact-resistant so it can survive a lot of abuse and damage. This makes it great for lugging around on your camping trips, or when you need to move around quickly during an emergency.

I also really liked that this system includes a Bluetooth module that can pair with an app on your smartphone so you can monitor charge progress in real-time.

After reviewing their power station, Jackery continues to impress me here with their solar power panels — this monocrystalline 100 watt solar kit operates at 23% efficiency.

This 9.1lb lightweight panel is also foldable and comes with a kickstand, so it’s good for taking on camping trips or using as backup power on a sunny day.

The solar charger even comes with 2 5V USB slots, so you can charge your smartphone directly from the panels. Good stuff.

4. Renogy 100W 12V Monocrystalline Solar Starter Kit With Wanderer 10A Charge Controller

Another quiet solar 100 watt panel kit from Renogy, this one is good for newbies who are into RVs, trailers, and other long-term outdoor adventures.

The 100 watts solar panel is quiet and easy to set up, coming with corrosion-resistant aluminum frames that last for decades with the right care.

These 100 watts solar panels come with electronic protections for overcharging, overload, short circuits and reversed polarity — you’re unlikely to fry this battery if you make a rookie mistake.

The regulator doesn't always hold the cables securely though so you should take care when moving the regulator.

5. RICH SOLAR 100 Watt 12V Polycrystalline Solar Panel

A popular 100 watt panel, this RICH SOLAR product can be used in a series or parallel depending on your solar power needs.

This panel is designed to work well on cloudy days with limited sunlight, though some users have found that the output is more like 50-75 watts than 100 watts.

Nonetheless, the 14 pre-drilled mounting holes make it easy to stick this on top of your RV, trailer, or shed and get going.

It doesn't come with the 4 mounting brackets that's normally included in systems like this, which is very inconvenient really.

PROS

  • Works in series
  • Low light performance
  • Robust tempered glass and anodized aluminum frame

CONS

  • Wattage limited sometimes

  • Arrived damaged for some users

  • Pricey


6. HQST 100 Watt 12V Monocrystalline Solar Power Kit

These efficient solar panels from HQST can produce up to 500 watt hours of power per day, depending on the conditions. This makes them good for powering everyday electronics and device batteries on trips.

The anti-reflective glass is also designed to withstand high winds and snow, so it’s good if you travel in different terrains and climates.

However, you basically only get the panel itself in the pack, so make sure you’re prepared with accessories. That's quite a pain because sometimes you don't really have the time or money to look for those other accessories, right?

An HQST 100 Watt 12 Volt Monocrystalline Solar Panel

PROS

  • Efficient monocrystalline panel

  • Withstands high winds and snow

CONS

  • Produces more voltage than advertised
  • No accessories included
  • Expensive

7. Rockpals 100W Foldable Solar Panel

Made with solar generators in mind, this foldable panel is portable and comes with a carry handle, so it’s good for camping trips and more temporary outdoor setups.

This product comes with various attachments and adaptors for all different generator types like this one or this one, so it’s compatible with a lot of gear.

However, many users claim that they never get close to 100 watts with this thing, so it might not be as efficient as it seems.

PROS

  • Various adaptors included
  • Foldable and portable

CONS

  • Stops working in 6-12 months for some users

Goal Zero is known for its Yeti portable power stations, and here is their interesting effort in the world of solar panels.

The Boulder 100 Briefcase actually folds up like a briefcase, as the name suggests, so it’s easy to carry around a campsite with you. It’s also very lightweight, which is handy if you’re a solo traveller.

However, this product is designed with other Goal Zero power stations in mind, so it’s not ideal if you’re not deep into the Goal Zero brand.

PROS

  • Lightweight
  • Foldable briefcase design

CONS

  • 1-year warranty

  • Designed for other Goal Zero products

9. Newpowa 100 Watts 12V Polycrystalline Solar Panel

I personally have used these solar panels to keep my batteries charged — one can easily charge my 100ah deep cycle battery on a sunny day.

However, beware that if you get a shadow or a leaf over one of the 72 cells on these panels, the entire power output can be cut by 50%.

That’s quite an issue!

A Newpowa 100 Watts 12 Volts Polycrystalline Solar Panel

PROS

  • Can produce 4-6 amps of power on an average day
  • Can charge deep cycle batteries quickly

CONS

  • Leaves and shadows are a problem
  • Uncommon connectors
  • Unclear instructions for rookies

10. ACOPOWER 100W Monocrystalline Solar Panel

These monocrystalline solar panels are good for houses, boats, trailers, and much more. My friend has a few on his home’s roof and he loves them.

They’re made from iron-tempered glass and corrosion-resistant frames, complete with a waterproof junction box that makes them resilient in all types of weather.

However, these solar panels are packaged without foam and often arrive damaged, so beware if you’ve got heavy-handed delivery people.

PROS

  • Robust construction
  • Decent price

CONS

  • Condensation can form in panels
  • Voltage seems limited
  • Damaged in transit often

11. ECO-WORTHY 100 Watt Solar Panel

Built to withstand wind, snow, and rain, these 100 watt solar panels are easy to install and can power 12V/24V batteries pretty well.

However, they perform quite badly on cloudy days and many users complain that they never see the wattage go above 75W even on the sunniest days.

You might be rolling the dice on these panels.

An ECO-WORTHY 100 Watt Solar Panel

PROS

  • Can withstand various weather conditions

CONS

  • Bad on cloudy days
  • Less than 100 watts output
  • Expensive
  • Poor construction

12. WindyNation 100 Watt Solar Panel Kit

My buddy uses a few of these 100 watt solar panels for his cabin in the woods, and he says that they can produce up to 350 watt hours of power per day on a GOOD day.

However, most of the time it’s a lot less than that.

These panels come with a solar controller included [1]  (complete with LCD monitoring screen) but the overall construction feels a little cheap.

It’s also polycrystalline, though they don’t make that obvious when you buy it.

PROS

  • Solar charging controller included

CONS

  • Parts sometimes missing
  • Cheap construction
  • Polycrystalline
  • User website is always down

13. ALLPOWERS Solar Power Panel 100W

These unique flexible solar panels are good for irregular surfaces such as tents and horse carriages where regular rigid solar panels won’t really work. They’re also lightweight (4.7lbs) and monocrystalline (23.5%).

That’s where the joy ends.

These panels have been a nightmare for me. They degrade and go cloudy over time, and it’s surprisingly easy to crack the surface and/or short circuit them.

An ALLPOWERS Solar Panel 100W

PROS

  • Flexible and bendy design

CONS

  • Short easily
  • Crack easily
  • Go cloudy after a while
  • Degrade over time

A 100 watt panel receiving at least 8 hours of sunlight per day will produce almost 1 kilowatt-hours per day or 30 kWh per month. Divide that usage of the refrigerator (115kWh) by 30 kWh per month and you get 3.8 solar panels.
