If a PV rack with a “type 1” module achieves a Class A fire rating, the installer can use any other “type 1” module and retain the fire classification. PV modules certified as Class C modules will only need to perform one fire test and provide information on the thickness of their glass, encapsulate, and substrate backsheet to obtain a The maximum flame spread is 6 feet for a Class A rated roof, 8 feet for Class B, and 13 feet for Class C. The slope of the test specimen is preselected, and since steeper slopes are more of a challenge due to melting material feeding the fire, the rating applies to the maximum slope passed.
