Summary

The Mayor of London, Sadiq Khan, is committed to increasing the amount of solar energy captured in London as part of his wider ambition for London to become a zero carbon city. The Mayor has developed the London Solar Opportunity Map with the 

UCL's Energy Institute

 and 

Centre for Advanced Spatial Awareness

, to help London businesses and other organisations to identify opportunities to install solar panels on their property.

The London Solar Opportunity Map accurately highlights opportunity areas for installing solar and storage in homes and businesses. It is based on the interpretation of LiDAR data (where laser technology is used to measure distances) collected and made available by the Environment Agency. It provides an initial estimate of the amount of electricity that could be generated from panels both on rooftops and at ground level. Whilst this model is based on the best available data and most realistic assumptions, a more detailed site-specific suitability study should be carried out before proceeding with installation. The current version of the London Solar Opportunity Map is based on data from 2019-2020. The data contains Ordnance Survey mapping and the data is published under Ordnance Survey's 'presumption to publish'. © Crown copyright and database rights 2023
