Do solar PV stations have a fire risk assessment framework?

Since solar photovoltaic (PV) stations are experiencing rapid growth, their potential fire risk needs to be studied as a priority to avoid catastrophic consequences. This study developed a temperature-dependent fire risk assessment framework and applied it to a typical solar PV station.

Do solar PV stations have a fire risk?

Those fire accidents have caused severe losses of assets and threatened human beings and the environment, acting as a barrier to its further practical implementation. The fire risk of solar PV stations should be investigated urgently because relevant fire accidents could usually cause severe consequences.

How to calculate fire risk of a solar PV station?

To overcome the challenges of lacking probabilities and subjective judgment, the overall fire risk of a solar PV station was calculated by combining fault tree analysis, Cloud-Analytic Hierarchy Process and Weighted Average Cloud Aggregation algorithms.

Are building related PV systems a fire hazard?

In 2017, a detailed report about fire incidents involving building related PV systems was published by the BRE National Solar Centre. According to this report (BRE 2017a), 58 fire incidents involving building related PV systems were reported since 2010 compared to a total of around 1 million PV systems installed in the UK.

What is a solar PV station?

A solar PV station is the popular name for grid-connected centralized PV systems. It functions as a centralized power station, typically ground-mounted, and the power supplied by such a system is physically not associated with an electricity customer .

How often do solar PV station fires occur?

The latter study obtained the frequency of an annual fire incident on rooftops with solar PV systems as 0.0289 fires per MW . Due to the lacked frameworks, undertaking the risk assessment of solar PV station fire accidents is still challenging.
