Cheshire East Council is fitting solar panels to the roof of its headquarters in Sandbach over the next two weeks.
The investment of just under £50,000 should be paid back within six and a half years and will have a predicted 20 year cumulative financial benefit to the Council of around £200,000.
The works to the Westfields building are expected to finish on November 18th.
Councillor Rod Menlove, chairman of the Cheshire East Energy Ltd company said: "This is significant move by the Council to adopt renewable innovations that reduce our costs and provide maximum value for residents.
"We are considering other buildings in the portfolio that meet the suitability criteria for similar technology."
