Not all portable solar panels are waterproof. To know the water resistance capabilities of a specific portable backpacking solar panel, it's important to check the product specifications or manufacturer's information such as its IPX rating or other splash-proof information. For example, the Anker 531 Solar Panel comes with IP67 waterproof protection that allows it to endure any weather conditions.

If waterproofing is a crucial requirement for your intended use, be sure to choose a solar panel specifically designed and certified as waterproof to ensure its durability and performance in wet or outdoor conditions.
