Installation Guidelines: Construction and Integrated PV Roof

The PV elements of the roof have to fulfill the requirements of wind loading, snow loading, fire resistance, and possible traffic for maintenance. This means that a PV panel made for ground mounting may not always be suitable for a BIPV application. The grab zone of a standard PV laminate is small, and the glass thickness may also be inadequate.

This is why Article 690.31(C)(2) requires securement at intervals no larger than 4.5 feet for USE-2 and PV Wire. The support requirements for cable tray are more stringent in 690.31(C)(2) than 334.30. One reason for the more stringent requirements is that PV wire as small as 12 AWG single conductor cable is common in PV systems.
