Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what information his Department holds on the number of rooftop solar panels in use in (a) Slough and (b) Berkshire.

The Government does not have data for the number of rooftop solar panels in total by parliamentary constituency; however, we do hold figures for domestic solar installations across parliamentary constituencies, and these are available online.

Our latest figures show that Slough has a solar PV capacity of 4.4MW across 1,312 domestic installations.

Across the nine parliamentary constituencies in Berkshire, there is 73.6MW of solar capacity over 19,218 domestic installations. Wokingham leads the charge with 11.9MW over 2,790 installations.
