UL 2703 Database

SolarAPP requires that the racking system is UL 2703-listed for grounding and bonding requirements in combination with the PV module models specified in a SolarAPP project. SolarAPP now maintains a database of eligible combinations of racking systems and modules per UL 2703.

Starting end-march 2022, SolarAPP will require that any racking system and module combination used on the application is present on the database. Based on the available products on the market with UL 2703 grounding and bonding data, the database will support the racking systems listed below.

If you cannot find your racking system below or are having trouble getting your combination approved, please reach out to the SolarAPP team for help at [email protected]. In your email, provide the appropriate documentation from the NRTL or manufacturer to support your claim for a compatible combination of racking systems and modules, and we will evaluate whether your equipment can be included in the database.

The following is a non-inclusive list of the racking system manufacturers that are not supported in SolarAPP, since the team has not been able to find any information on the UL 2703 compatible modules for grounding and bonding.
