London Solar Opportunity Map
The Mayor's ambition to increasing the amount of solar energy in London
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 Mayor’s Solar Action Plan sets out how City Hall programmes are expected to more than double London’s current solar energy capacity. But the Mayor thinks London can, and should, go further than this and wants to provide support to local government, businesses and others to install more solar in London.
How data is collected
Through spatial mapping and access to technical support the London Solar Opportunity Map accurately highlights opportunity areas for installing solar and storage in homes and businesses.
The London Solar Opportunity Map 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.
