Implication

Observational and modeling analysis demonstrates severe dust events reduce photovoltaic power output by up to 80%, highlighting vulnerability of solar tracking systems to atmospheric aerosols.

Key Points

Investigate the impact of severe dust events and associated optical and geometrical characteristics on solar radiation components and solar photovoltaic power generation across the Mediterranean Basin.
Analyzed four severe dust events across multiple Mediterranean sites between 2021 and 2022 using ground-based remote sensing observations.
Modeled radiative transfer using the libRadtran package and METAL-WRF scheme, and simulated photovoltaic (PV) generation for fixed-tilt and two-axis tracking systems using the Global Solar Energy Estimator (GSEE).
Atmospheric dust attenuated direct solar radiation (DNI) by 60% to over 80%, while global horizontal irradiance (GHI) losses ranged from 5% to 25%.
Dust-induced PV power losses reached approximately 45% for fixed-tilt systems and roughly 80% for two-axis tracking systems due to high DNI sensitivity.
Sensitivity analyses revealed that Solar Zenith Angle (SZA) was the primary factor modulating PV generation loss, followed by Aerosol Optical Depth (AOD).
