Fire Test Method for Flat Roofs with Photovoltaic (PV) Modules

Jan 28, 2025

In their pursuit of advancing fire safety for photovoltaic (PV) systems, researchers at FRISSBE-ZAG, have authored a document titled Fire Test Method for Flat Roofs with Photovoltaic (PV) Modules. This document presents ZAG's approach to evaluating the fire safety performance of PV systems on flat roofs.

The document outlines a systematic methodology to simulate and analyze fire scenarios involving PV systems. Key features include:

  • Fire testing begins underneath the PV modules to replicate real-world ignitions, such as those caused by electrical faults.
  • Rather than isolating PV panels, the guide emphasizes assessing the entire system, including the roof’s role in fire dynamics.
  • Using a wood crib as the ignition source ensures the natural progression of fire, providing repeatable and comparable scenarios.
  • Extensive experimental campaigns have been conducted with various panel types, membranes, and insulation materials, ensuring broad applicability and reliability of results.

The document is structured with sections on scope, normative references, terms and definitions, test methods, procedures, observations, measurements, and reporting. By offering detailed insights, it aims to harmonize testing practices and improve PV system safety globally.

This publication reflects FRISSBE's dedication to innovation and collaboration in fire safety. We welcome feedback from the fire safety community and stakeholders to refine and advance the proposed methods.
