Naumai 4.2MVA Solar Farm

McKay were engaged by Infratec in late 2023 to provide a fast-tracked construction programme for their 4.2MVA (4.79MWDC) solar farm, located south of Dargaville in the Northland region. The Naumai Solar Farm consists of 7,290 PV modules arranged into 243 strings of 30 panels. 

This utility scale, ground mount solar farm has been constructed on a 5.5ha site with McKay responsible for all aspects of electrical installation at the site. This included:  

  • LV DC & AC cabling and power systems 
  • MV cabling installation and termination,  
  • earthing system installation,  
  • trenching and directional drilling to facilitate cable placement.  
  • Site assembly of the site inverter and MV skid 
  • Installation of control and protection panels, CCTV, weather stations and fibre/copper comms for the control systems 

McKay were also responsible for the testing and commissioning of the site, providing technicians for the pre-commissioning, cold and hot commissioning processes.  

Our client for this project provided positive feedback around McKay’s onsite performance and quality of work, and the pace at which the team worked.  

Our onsite team exemplified McKay’s commitment to Health and Safety, and efficient work practices, and were able to also assist the client to improve constructability of the site, where roads had already been built above cable routes and facilitated efficient and effective solutions to these challenges.
