6 FAQs about [Photovoltaic inverter explodes in thunderstorm weather]

Can severe weather damage a solar PV system?

Severe weather events strong enough to cause damage to a solar PV system occur in nearly every region of the country. The Federal Emergency Management Agency (FEMA) produces a National Risk Index (NRI) which details 18 weather and environmental parameters at a county level. Use the NRI tool to look up weather risks at your site.

How does weather affect PV performance?

12% of PV maintenance logs referenced either ambient or extreme weather conditions. Performance impact between event and non-event days is highest for snow (54.5%). Low performance driven by plant age, size, location & weather event characteristics. Data fusion with machine learning extends current methods for energy resilience.

Can a solar PV system be made more resilient to severe weather events?

On-site solar photovoltaic (PV) systems can be made more resilient to severe weather events by leveraging lessons learned from field examinations of weather-damaged PV systems and from engineering guidance resources. Total array loss from Hurricane Maria. Photo from Gerald Robinson, Lawrence Berkeley National Laboratory. August 2020 Derecho event.

Which weather events affect PV plant production?

Discussion This analysis identifies that the three primary CEWEs impacting PV plant production across the US are hurricanes, snow, and storms. The coupled analysis of production and weather data showed lower and more variable performance across weather events.

How does solar irradiance affect a PV plant?

Short-term enhancements in solar irradiance (i.e., overirradiance) may lead to energy losses at PV plants. Overirradiance events are often of short duration (lasting from one to several minutes), but can have significant impacts on PV operations.

How does machine learning affect photovoltaic systems?

Machine learning analysis identified key features in determining if a day is categorized as low performing, such as low irradiance, geographic location, weather features, and site size. This analysis improves our understanding of compound, extreme weather event impacts on photovoltaic systems.
