Hundreds of solar panels are being installed in Exeter as part of a renewable energy drive.
The 800 panels, on two roofs of the Civic Centre and three other sites across the city, will generate around 184,000 kilowatt hours of electricity per year – enough to power the equivalent of 53 houses.
The installation will help reduce city council energy costs through the government's Feed-in Tariff scheme, which pays people and organisations for the energy they generate.
Following the installation, three wind turbines will be removed from the civic centre roof and donated to a sustainable initiative for schoolchildren.
Councillor Ian Martin, lead councillor for business transformation and human resources, said: "Installing solar panels on our buildings is an attractive proposition with significant financial returns. This really is a good time to benefit from solar energy."
The solar photovoltaic systems on the Civic Centre will be completed within two weeks. Work on the other buildings is due to be finished by April.
