Photovolt Development Partners, behind the scheme, said the project would have powered the equivalent of 275,000 homes, with the solar panels in place for 40 years. But it met with fierce opposition from campaigners who complained that the solar farm would be an “ocean of glass and steel” across the Oxfordshire countryside.Developers argued the project was set back from the grounds of the palace itself, which is a Unesco world heritage site. They said the scheme, which would have been divided into three linked areas, would provide grazing for livestock, new footpaths and cycle paths, and provisions for nature.
