Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the long-term sustainability of the solar panels being installed under the Great British Energy scheme in relation to their (a) lifespan, (b) efficiency degradation and (c) recyclability.

We expect panels delivered under this scheme to have an estimated lifespan of 30 years [with a 0.5% yearly attrition rate] which is based on our published assumptions.

Recyclability is a critical factor in the sustainability of solar panels and the schools and NHS trusts receiving solar panels under this scheme will be responsible for ensuring appropriate end-of-life management of panels under this scheme.
