6 FAQs about [Solar Photovoltaic Power Generation Haze Weather]

How does haze affect solar photovoltaic (PV)?

Solar photovoltaic (PV) strongly impacted by environmental phenomena induced by haze. Industrial exhausted aerosol, dust storms particles, bushfire smoke cut irradiance. Haze changes in received solar spectrum, and higher bandgap PV 20-40% cut. Pollution-related haze causes substantial annual revenue loss to PV operators.

How does haze affect solar energy?

Haze also causes changes in the received solar spectrum, and higher bandgap PV materials are more affected by the presence of haze and aerosols in the atmosphere by 20-40% than low bandgap semiconductors. In many cities throughout the world, pollution-related haze causes substantial annual revenue loss to PV operators.

Does global haze affect PV performance?

Global haze as well [ 185] contributed to the growing trends in global warming, and these two are tied together. As PV performance also decreases with temperature, global warming, in general, reduces PV performance (although in snowy regions, it can decrease snow-related losses [ , , , , , ]).

Does urban haze affect PV power plants?

Wu et al. [ 112] implied that the PV output of power plants in Hangzhou, decreased by 5.25 ± 1.19% and 6 ± 1.16% due to urban haze in 2017 and 2018, respectively. Furthermore, the effect of urban haze on PV power plants was more severe in Tianjin, where had experienced PV power reduction of 8.77 ± 0.9% for one year since Dec 2018.

Does haze affect PV module power output?

They [ 105] reported 17.8 % decrease in PV module power output during a haze event. Based on economic analysis [ 105 ], an 8 % reduction in net present value ( NPV), and a slight decrease in internal rate of return ( IRR) were reported, while the payback period ( PBP) increased around 10 % when haze was present in Malaysia for 6 months.

How do hazy and clean sky conditions affect PV power output?

They measured the Pmax of a PV panel, irradiance ( G), and module temperature ( θmod) for two periods of hazy and clean sky conditions to quantify production losses in PV modules. They [ 105] reported 17.8 % decrease in PV module power output during a haze event.
