Yes. Ratings are available for solar module junction boxes in the form of IP ratings, which stand for Ingress Protection ratings.

These ratings mainly specify the protection that the junction box provides against two main natural elements that can cause damage to the junction box – dust and water.

  • IP 67 protection ensures that the junction box is completely resistant against dust and temporary immersion in water.
  • IP 65 is a lower level of protection against these factors

Solar Mango recommends that you choose an IP 67 rated solar module junction box.

Data regarding these will be available in the panel datasheet.
