High resolution global spatiotemporal assessment of rooftop solar photovoltaics potential for renewable electricity generation.

ABSTRACT: Rooftop solar photovoltaics currently account for 40% of the global solar photovoltaics installed capacity and one-fourth of the total renewable capacity additions in 2018. Yet, only limited information is available on its global potential and associated costs at a high spatiotemporal resolution. Here, we present a high-resolution global assessment of rooftop solar photovoltaics potential using big data, machine learning and geospatial analysis. We analyse 130 million km² of global land surface area to demarcate 0.2 million km² of rooftop area, which together represent 27 PWh yr^-1 of electricity generation potential for costs between 40-280 $ MWh^-1. Out of this, 10 PWh yr^-1 can be realised below 100 $ MWh^-1. The global poten
