Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate his Department has made of the obsolescence date of the current generation of photovoltaic panels.

The lifespan of a solar panel can vary depending on environmental factors and standards of maintenance. Typically, the panels have a guaranteed lifespan of 25 years, though many will continue to produce electricity reliably after that point. Decisions about the precise point at which it is no longer economical to maintain ageing panels are left to solar farm operators.
