UL 2703 Database

The International Residential code requires that the solar racking system is tested for grounding and bonding, and fire classification, in combination with the solar module. SolarAPP+ only supports listed systems with a class A fire rating. SolarAPP now maintains a database of eligible combinations of racking systems and modules that comply with the UL 2703 listing.

If you cannot find your racking system below or are having trouble getting your module/racking system combination approved, you can submit a request to update the database here. You can generally find a table of approved combinations in the "Racking Manufacturer's Installation Instructions."


You can always reach out to the SolarAPP team for help at support@gosolarapp.org if you need more assistance.

Notes:

The SolarAPP+ tool does not qualify the attachment type, or footing, for most rooftop installations. The installer has attested to follow the manufacturers installation instructions and may use the attachment types detailed there. The attachment type installed shall be appropriate for the surface material.

Racking systems should not be confused with attachments such as the following:

  • S-5! Clamps
  • Roof tech RT-MINI
  • Pegasus Solar (Mounts)
