A harmonised, high-coverage, open dataset of solar photovoltaic installations in the UK

This article presents the results of a major crowd-sourcing campaign to create open geographic data for over 260,000 solar PV installations across the UK, covering an estimated 86% of the capacity in the country. In particular, it focuses on capturing small-scale domestic solar PV, which accounts for a significant fraction of generation but was until now very poorly documented. The dataset suggests nameplate capacities in the UK (as of September 2020) amount to a total of 10.66 GW explicitly mapped, or 13.93 GW when missing capacities are inferred. Our method is applied to the UK but applicable worldwide, and compatible with continual updating to track the rapid growth in PV deployment.
