A study by engineers at Australia's University of New South Wales (UNSW) shows that aerosols and greenhouse gas emissions reduce the productivity of PV installations, with variations across regions.
Researchers from the UNSW School of Photovoltaic and Renewable Energy Engineering have mapped PV productivity across future emissions scenarios in various parts of the world, with a focus on maximizing potential and minimizing costs in warmer climates.
The study’s models reflecting different emission-level scenarios made such differences clear across global regions. The study found that, with increasing climate change, solar resources increased in West and Central Europe, South America, and Central North America. In contrast, global horizontal irradiance (GHI) reductions were predicted in northeast Africa, the Tibetan plateau and South Asia.
