All three barns have roofs facing in the same direction, on a bearing of 200 degrees south-southwest and have a pitch of approximately 15 degrees from horizontal. The proposal here was for three distinct PV arrays to be installed, resulting in the 134kW system.
A GPRS generation meter was also needed for the installation, to allow us to gather data remotely for submission over the first 12 months of operation.
For the electrical connection, our proposals differed slightly from the tender document’s recommendations, because we proposed a different distribution arrangement, thereby saving the company money and speeding up the installation process. A series of isolators were installed across each building to allow sections to be switched off independently. The NWT Energy team are highly educated and specialised in electrical processes and ingenious solutions, hence we were able to find the winning procedure for this project.
