Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate he has made of the number and proportion of the solar panels to be installed on new homes that will be manufactured in the UK; and what steps his Department is taking to support the domestic manufacture of solar (a) panels and (b) batteries.

Though the UK will likely require solar panel imports in the short to medium term, several firms are involved in assembling panels and manufacturing innovative solar, such as thin film. The recently published Solar Roadmap sets out actions for maximising opportunities arising from commercialisation of innovative solar technologies and upscaling production of balance of system components.

As laid out in the recent Industrial Strategy's Advanced Manufacturing Sector Plan, Batteries is a frontier sector. We will invest £452m in support of Battery Innovation to compete in a challenging global marketplace and meet domestic demand across the supply chain.
