Portable Solar Panel Sizes – Models and More (20-100W)

Portable solar panels are becoming more of a necessity amongst campers and backpackers due to their ease of use and charging capabilities.


Portable solar panel sizes vary greatly because they can be unfolded and refolded into easy-to-carry packages. These can fit easily in a backpack while hiking. The smallest of these solar panels can be as little as seven watts, and the largest ones can be 100 or more watts in size.


In this article, you’ll find the top portable solar panels ranging from very small (20W) to very large (100W).

Many of these are portable and the smaller ones can be used on the back of your backpack while hiking.

The larger ones are very portable but unfold into large sizes, making them capable of attaching to your tent, vehicle, or you can simply place them on the ground when using them.
