This review examined the many environmental factors that influence solar PV performance. The individual and combined effects of several key factors must be understood and mitigated to optimize PV output: solar irradiance, temperature, cloud cover, dust and pollutants, snow cover, albedo, and extreme weather events.
Solar irradiance is the most significant factor affecting PV performance, with the strongest impact near the equator. Higher temperatures reduce PV efficiency, with a typical loss of 0.4–0.5 % loss per 1 °C increase.
Cloud characteristics Cloud cover strongly impacts solar PV output, primarily by reducing the Direct Normal Irradiance (DNI) received [90, 91]. Cloud cover reduces PV capacity factors by 50 % in Northern Europe, and by 15–30 % in the US and China .
Snowfall significantly affects solar PV modules, especially in regions with extended periods of snow coverage including Canada, Russia, and northern US states. Snow cover has complex effects on PV generation due to the interaction of snow lying on the modules and reflected light from surrounding snow-covered surfaces .
Jost et al. analyzed PSC performance dependence on the incident solar irradiance and air temperature and observed a weak effect of diurnal variations in solar irradiance on the photovoltage hence the output power followed the maximum current density variations. [9, 11] A weak temperature dependence of the PSCs' PCE was demonstrated. [20, 26]
