This paper analyses the safety, reliability, and resilience of PV systems to extreme weather conditions such as wind storms, hail, lightning, high temperatures, fire, and floods.
What is solar photovoltaic (PV)?
This research specifically targets solar photovoltaic (PV) systems, a rapidly expanding renewable energy source, distinguishing it from other studies, like Brás et al. (2023), that analyze the effects of extreme weather on various energy systems (wind, hydro, nuclear, etc.).
Using reanalysis weather data from 1986 to 2021 and a high-resolution global inventory of PV installations, we assess the impact of extreme low-production (ELP) events across various regions. Our results reveal that regions between 60°N and 60°S experience an average of 27 ELP events annually, with 17% of these events being high-intensity.
How does weather affect PV power?
For example, the concurrence of high temperatures and overcast conditions during one or more consecutive days can reduce PV power outputs. Changes in the fre-quency of these extremes can either reinforce or mitigate PV power intermittency, with implications for grid planning and operations.
Do heatwaves and temperature extremes affect solar PV system classification?
The effects of heatwaves and temperature extremes on solar PV system classification examine how elevated temperatures can diminish solar panel efficiency and even lead to overheating, hence reducing energy output.
Are solar PV systems resilient to weather events?
As solar PV systems become increasingly essential to global energy strategies, sustainable development, and net-zero objectives, enhancing their resilience to weather events is imperative across nations, regions, and organizations, as demonstrated in Fig. 20.
Are PV panels combustible?
The PV panels themselves are not combustible at the high temperatures indicated, nor is the panel frame. However, if dry leaves or other flammable materials get on or under the hot PV panels, there is a real fire hazard. The question is whether the installations (cables) can pose a fire hazard.
