Fire protection level of photovoltaic panel backsheet

Are photovoltaic systems fire safe?

Fire Safety of Photovoltaic System. Review of PV module international test protocols. A novel fire behavior test protocol for PV modules. The assessment proposed test focuses on the fire behavior of the PV roof sample. The photovoltaic (PV) systems fire risk has grown up reaching a size that is no more negligible.

Can a PV module be mounted over a fire rated roof?

The old version of UL1703 provided a fire performance classification for the PV module, and the UL Whitebook provided a description that the module had to be mounted over a fire rated roof of the same or higher fire class. (Class C module over Class C, B, or A roof).

Do backsheet materials influence the flame spread behaviour of PV modules?

The flame spread behaviour as well as the flame spread or propagation was influenced by the materials used in the construction of PV module backsheets. Four types of backsheet materials available on the market were selected in order to evaluate and compare the reaction-to-fire performances of these products.

Can a PV system be installed on a fire rated roof?

PV system onto a fire-rated roof changes the dynamics of fires that develop. If a fire develops on a roof with a PV system, the presence of the modules can keep the released en rgy closer to the roof and increase temperatures and heat fluxes to the roof. Thus, fires that could otherwise

How to choose a backsheet foil for a PV module?

In the PV industry, the guidelines on choosing the backsheet foils are usually the ones set out in the IEC standards [13, 23, 23]. The critical aspects introduced by the backsheet foils to PV modules are clearly shown in the IEC retest guidelines .

Can a high-rated reaction-to-fire PV module reduce the spread of fire?

In the case of fire, a high-rated reaction-to-fire PV module could drastically reduce the spread of fire and flame propagation. In order to comply with Italian reaction-to-fire standard requirements, a PV module manufacturer should assess the material chosen for building a proper reaction-to-fire PV module.
