FAQs 6

What is photovoltaic (PV) power prediction?

Abstract: Photovoltaic (PV) power prediction is a key technology to improve the control and scheduling performance of PV power plant and ensure safe and stable grid operation with high-ratio PV power generation.

How does atmospheric pm affect PV generation?

We consider attenuation caused by both atmospheric PM and PM deposition on panels (soiling) in calculating the overall effect of PM on PV generation, and include precipitation removal of soiling and the benefits of panel cleaning.

Can cleaning solar panels reduce photovoltaic electricity generation?

Our findings highlight the benefit of cleaning panels in heavily polluted regions with low precipitation and the potential to increase PV generation through air-quality improvements. Air pollution and dust can reduce photovoltaic electricity generation.

Does soiling affect PV efficiency?

When panels are left uncleaned by anything except natural precipitation, the overall impact of PM on PV efficiency is dominated by soiling (over atmospheric aerosol attenuation).

How is atmospheric aerosol attenuation calculated?

The effect of atmospheric aerosol attenuation is calculated by taking the difference between the two scenarios. The soiling effect is estimated by the attenuation of irradiance due to PM accumulated on top of the panel, that is, soiling.

Can air pollution and dust reduce photovoltaic electricity generation?

Air pollution and dust can reduce photovoltaic electricity generation. This study shows that, without cleaning and with precipitation-only removal, particulate matter can reduce photovoltaic generation in polluted and desert regions by more than 50%, with soiling being the major cause of reduction.
