Your London Solar Opportunity Map was launched in 2020 (https://www.london.gov.uk/what-we-do/environment/energy/energy-buildings...). Could you demonstrate how it has had a positive impact on the installation of solar PV in London?

The Solar Opportunity Map is an interactive tool that was developed to support stakeholders looking to develop PV projects to better understand the potential for PV generation on buildings across London. This helps them to identify areas where there is opportunity to develop PV projects, provides an initial understanding of the scale of that opportunity and informs subsequent feasibility study.

The map was launched in September 2020 and has been well used by stakeholders exploring the opportunity for PV installations. Monitoring traffic to the site has shown that it has had 4,227 page views of which 3,991 were unique page views since its launch. There is no direct correlation that we can use to estimate the amount of solar installation undertaken as a consequence of using the map.  Data is currently not available on the map for any solar installations since September 2020 but my officers are looking to see if it could be periodically updated to capture information on solar installations.
