King’s College Cambridge has completed a year-long restoration of its Chapel roof, addressing urgent issues with its lead covering. The project, deemed a once-in-a-generation opportunity, not only restored the roof but also included the installation of 438 new solar panels. Recognizing the Chapel roof as a significant site for renewable electricity generation, the College seized the chance to integrate photovoltaic (PV) panels during the restoration.

The approval for the PV installation came after extensive consultations with various bodies, including the Diocesan Advisory Committee, Historic England, and the Society for the Preservation of Ancient Buildings. Work on the roof restoration began in September 2022, with the installation of REC Alpha 420 Pure-R photovoltaic panels on both north and south slopes. Anticipated to generate 123,000 kilowatt hours per year, the panels contribute to the College’s goal of decarbonizing operations by 2038.

Shane Alexander, the College Project Manager, highlighted the complexity of the project, emphasizing the coordination between roof restoration and panel installation. The initiative is expected to reduce the College’s carbon emissions by over 23 tonnes annually, equivalent to planting 1090 trees. Combined with existing panels, the Chapel's photovoltaic system will decrease the main site's annual electricity demand by about 5.5%.

The installation aligns with the College’s broader strategy to achieve sustainability goals. The Chapel joins other churches and cathedrals, such as Salisbury and Gloucester Cathedrals, in adopting solar panels. Funded entirely by philanthropic donations, the project marks a significant step in the College's commitment to environmental stewardship.

Rev Dr Stephen Cherry, Dean of King's College Chapel, emphasized the long-term carbon-saving impact of the solar panels, viewing them as part of the College’s effort to enhance efficiency and contribute to moral and ethical wellbeing. Caroe Architecture Ltd and Barnes Construction, in collaboration with regional firms experienced in historic conservation, delivered the project. Heritage and conservation-accredited architect Oliver Caroe praised the exemplary leadership of the College Fellowship and team, noting the project's inspiration for others and its alignment with the University's research and academic goals.
