Top 3 Best Portable Solar Panels for Off-Grid Use

The best portable solar panels provide utility for a multitude of activities. They provide renewable, free energy while at home or on the go.

In general, these systems work by collecting sunlight within the panel itself and are then able to transfer power to a solar generator or electronic device.

Basically, portable solar panels are small-scale solar panels that you can carry with you if need be. They vary in size and weight, making some more prone to camping or hiking than others.

This article will review the best foldable solar panels, with exception to the Boulder 50, that are suitable for your trailer, RV, rooftop, or for extended camping trips where you could use a heavier-duty solar panel than some of the really small ones you can find online.

The solar panels featured below range from 50 watts (Boulder 50) to over 100 watts (all the rest featured) of power per panel.

If you’re looking for a solar charger that is specific to recharging cell phones and other small devices, I recommend checking out my blog post dedicated to this topic.

I answer FAQs and give my top three solar panel choices for small devices here: How Long Does It Take a Solar Charger to Charge a Cell Phone?.

2) Elecaenta 120W Portable Solar Panel

This foldable solar panel from Elecaenta is powerful with 120W of output power. I have two of these solar panels to use with my Jackery 1000 and EcoFlow River Max power stations.

After testing this panel in summer daylight, I was able to get about 96-98W of power from this panel. This is a good number to get because it’s just over 80% efficient. Any solar panel like this that is capable of that type of efficiency is typically a high quality solar panel.

Key Features

  • Folds four times over to be ultra compact
  • Comes with 10 different adapters for various devices
  • Comes with four carabiners to attach the panel to a car, fence, or other surface

Pros

  • High efficiency
  • Can connect to multiple different devices
  • Has USB connectivity directly from the panel
  • Kickstand
  • Inexpensive compared to similar panels

Cons

  • Might be too large to fit into a standard backpack when folded

Verdict

This is my favorite portable solar panel that I’ve tested and used myself. It has nearly every aspect I’m looking for in a portable panel: carrying handle, collapsibility, kickstand, adapters, long wires to connect to devices, and a great output.
