Ground mount solar farm

Project Outline:

The ground-mounted solar installations will be operational for 25 years and generate enough low-carbon energy to provide power for around 9,000 homes, while saving up to 14,000 tonnes of carbon per year.

The project has seen the development of three sites in Nottinghamshire: Welbeck Colliery in Mansfield, Gedling in Lambley and a third site in Bilsthorpe. The fourth site is in Askern, South Yorkshire. Each solar farm is being monitored by Anesco’s maintenance system AnescoMeter which will ensure they continue to operate at their optimal capacity.

Welbeck Colliery was the the first site to come online. The installation covers an area of almost 32 acres. It comprises of 44,160 solar panels mounted on around 15km of frames that have a combined generation capacity of 11.2MW – sufficient energy to power more than 3,450 homes in the local area.

This site was followed by 5.74MW installations at both Gedling and Bilsthorpe and a 4.9MW installation at Askern. A 4.2MW installation at Oxcroft is currently under construction.
