"Nature Communications" is the first research to evaluate the potential of global rooftop solar photovoltaic power generation

Researchers at the University of Cork (UCC) SFI Energy, Climate and Ocean Research Center MaREI, in collaboration with international research partners, conducted the first detailed global assessment of the power generation potential of rooftop solar photovoltaic (PV) technology

Due to improved deployment capabilities and reduced costs, rooftop solar photovoltaic (PV) technologies, such as rooftop solar panels used in homes, commercial and industrial buildings, are currently the fastest deployed power generation technology and are expected to provide global electricity by 2050 25-49% of demand

The research team included lead author Siddharth Joshi, UCC colleagues Professor Brian ó Gallachóir, Dr.

The author found that at a cost of US$40-280 per MWh, a global power generation potential of 27 kWh per year can be achieved, with Asia, North America and Europe having the largest power generation potential

"For the first time, we can combine big data, machine learning and GIS to analyze the temporal and spatial characteristics of global rooftop photovoltaics with higher accuracy

The authors conclude that their findings will have important implications for sustainable development and climate change mitigation efforts

Co-author Professor Brian ó Gallachóir commented: “The potential of rooftop solar energy at 27 PWh per year is very significant
