Solar energy output of India is reduced significantly by air pollution

Physics World

Air pollution in India is reducing the energy output of some solar panels as much as 52%. That is the conclusion of researchers who have modelled the effects of particulate pollution on solar irradiance in 2001–2018. Having abundant insolation, the country was ranked fifth in the world for solar energy capacity in 2020.
