Solar photovoltaic (PV) technology has emerged as a crucial component in the transition towards clean energy. However, real solar PV installations face challenges, such as soiling, which can limit their efficiency. This work investigates the influence of natural soiling on PV module performance, considering factors such as geographical location and weather conditions. A thermo-electrical model, validated against experimental data, is developed to assess the effect of transmittance reduction on energy losses due to soiling. A comparative analysis is conducted to evaluate soiling over horizontal surfaces, and its influence on the projected yearly energy yield of PV systems. Preliminary findings indicate maximum predicted reductions in energy yield over one year of 32%, 25%, 17% and 12% in Oman, Nigeria, Indonesia and Australia, respectively, compared to the reference energy generation under clean conditions, which amounts to 469, 441, 443 and 393 kWh/m2y

Abstract
Solar photovoltaic (PV) technology has emerged as a crucial component in the transition towards clean energy. However, real solar PV installations face challenges, such as soiling, which can limit their efficiency. This work investigates the influence of natural soiling on PV module performance, considering factors such as geographical location and weather conditions. A thermo-electrical model, validated against experimental data, is developed to assess the effect of transmittance reduction on energy losses due to soiling. A comparative analysis is conducted to evaluate soiling over horizontal surfaces, and its influence on the projected yearly energy yield of PV systems. Preliminary findings indicate maximum predicted reductions in energy yield over one year of 32%, 25%, 17% and 12% in Oman, Nigeria, Indonesia and Australia, respectively, compared to the reference energy generation under clean conditions, which amounts to 469, 441, 443 and 393 kWh/m2yI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
