Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether he has made an estimate of the amount of non-residential building roof space that is (a) available and (b) suitable for the installation of solar panels.

The Government does not take a prescriptive approach to the amount of rooftop solar deployment required, nor to the mix between installation on domestic and non-domestic properties. Therefore, no such estimate has been made. However, the Government is clear that rooftop solar will play an important role in achieving its ambition of tripling existing solar capacity by 2030. Further details will be included in the upcoming publication of the Solar Roadmap.
