King Charles III hopes to use solar energy to power his Norfolk retreat.

Sandringham Estate has applied for planning permission to site 2,000 panels on land off Admirals Drive, near the Royal Sawmill.

A planning statement says it forms part of the estate's "ongoing commitment to sustainability and promoting environmental practices" and follows the installation of a small solar array to the roof of Sandringham House in 2022.

"The solar system has been specified to deliver approximately 1.9MW per annum and is designed to meet the majority of the Estates’ electricity demand, with a modest amount of spare capacity exported to the grid," it adds.

"Power will be sent from the power system to the Estate’s three principal power consumers - the sawmill, visitor centre and house - using existing infrastructure which, as part of the project, will be upgraded and adapted as required."

The site is currently a grass paddock, used for grazing horses at the nearby Royal Stud, which is "well-screened" by the surrounding landscape.

The statement says the impact of the proposal would be "slight or moderate", adding: "Considered as part of the wider estate-managed landscape, a modest solar array such as that proposed should be viewed as no more incongruous than the existing, intensively grazed paddock, and a necessary part of managing a sustainable, living, working landscape."

King Charles has been moving Sandringham towards more environmentally friendly management since taking over the running of the 21,000-acre estate from his father, the late Prince Philip, in 2017.

He has turned its farms organic, planted trees and hedgerows and overseen a programme of "ecological delivery" which includes installing bird boxes and wide field margins to encourage insects.

The monarch has been a regular visitor to Sandringham since revealing he was undergoing treatment for cancer in February.

A decision on the solar farm is expected later this year.
