Lidl has been granted permission to install an array of solar photovoltaic (PV) panels on the roof of its new Regional Distribution Centre outside Newbridge.
The area to be covered will measure 8,860 square metres.
Also in the plans are inverters and electrical cabling for the building at Littleconnell.
Hundreds of workers are on site at the 54,000 sq/m facility building - about the size of seven football pitches - on the side of the R445 between Naas and Newbridge.
The sprawling 31 hectare site (77 acres) is located between Naas Enterprise Park and the Pfizer plant and needs traffic restrictions in the area because of the volume of vehicles entering and exiting.
John Paul Construction is the main contractor for the €80m project which has imposed roadworks along the R445.
It is due to open in coming months and will employ 350 staff.
The warehouse will be one of the biggest in Ireland and will include 352 parking spaces to cater for staff.
A total of 32 cycle parking spaces are also provided for.
A 400m stretch of the R445 regional road will be upgraded as part of the proposed development including junction reconfigurations and partial realignment.
