The UK plans are mostly wind e.g. from the latest carbon budget:
> Low-carbon supply: by 2040, our Balanced Pathway sees offshore wind grow six-fold from 15 GW of capacity in 2023 to 88 GW by 2040. Onshore wind capacity doubles to 32 GW by 2040 and solar capacity increases to 82 GW
And once you multiply by capacity factor the solar and onshore wind are about equal so solar will be less than a third of modern renewables.

Plus UK wind peaks in the winter.
