The effects of coal dust on solar PV plants

An international research team studied the solar PV impact of emissions from a coal-fired power plant in the Atacama Desert, finding that after five months of exposure, the deposited dust on co-located PV panels reached a maximum of 1. 63 mg/cm2 with a 23 % reduction in photocurrent. The accumulation at the co-located plant was 3 times greater than nearby PV sites with similar coastal climate conditions. Aware of the operational and maintenance costs (O&M) costs to combat PV panel soiling in arid and heavily industrialized areas, a group of researchers from Chile and Spain investigated the impact ...
