How many solar PV systems are there in 2022?

According to the International Energy Agency Photovoltaic Power Systems Programme, the cumulative installation capacity of solar PV systems worldwide ascended to 1,185 GW at the end of 2022 . A solar PV station is the popular name for grid-connected centralized PV systems.

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 .

What is fault tree regarding fire spread accident in solar PV station?

Fault tree regarding fire spread accident in the solar PV station with meanings of symbols referring to Table 4. Table 1. Symbols and their meanings in the fault tree. The fire spread accident is likely to occur when two conditions satisfy: the generation of fire (M1) and the spread of fire (M2).

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.

Can lightning cause a fire in a solar PV station?

Lightning can also give rise to fire ignition in solar PV stations. Due to the big area, the solar PV station can be subject to lightning strikes, and lightning is likely to cause electrical equipment damage, which poses a potential fire risk to solar PV station .
