Solar panels are to be installed on Guernsey Post's headquarters in what is described as the largest solar array in the Channel Islands, the postal service and Guernsey Electricity say.
The organisations said the array, capable of producing about 200,000 kWh of electricity a year, would help them both "reach significant milestones in their ambitions for the generation and use of renewable energy".
Guernsey Post added that the array would "generate the equivalent amount of energy required to power Guernsey Post’s entire fleet of vehicles, at a time when the company is making significant strides towards conversion to a fully electric fleet".
Guernsey Post plans to have 40 electric vehicles in its delivery fleet by the end of 2018, with a commitment to increase this to 80 by mid-2019.
Subject to planning approvals, and after a tender process, it is hoped the array would be installed in the first half of 2019, the organisations said.
