6 FAQs about [Photovoltaic panel level classification]

Are photovoltaic panels fire rated?

Effective January 1, 2015, Rooftop mounted photovoltaic panels and modules shall be tested, listed and identified with a fire classification in accordance with UL 1703. The fire classification shall comply with Table 1505.1 of the California Building Code based on the type of construction of the building.

What is the fire classification of a roof mounted photovoltaic system?

1509.7.2 Fire classification. Rooftop mounted photovoltaic systems shall have the same fire classification as the roof assembly required by Section 1505. Different language was approved in the IRC. M2302.2.1 Roof‐mounted panels and modules.

Are rooftop PV panels fire rated?

Per Section 1510.7 and 1505.9, rooftop mounted PV panel systems that are directly attached to the roof assembly shall be tested, listed, and identified with a fire classification in accordance with UL 1703 and UL 2703. The fire classification shall comply with Table 1505.1 based on the type of construction of the building.

What types of PV modules are available?

Several Type 1 and Type 2 PV modules are now available, so these two types, with the mounting system, should be evaluated as soon as possible. As other types become more common (particularly Type 7 and 8) these will also be important for Class B required fire ratings. UL1703.

Can photovoltaic panels be installed on state property?
