At 422.4 kWp this system is the largest solar power system in New Zealand currently.
Mainfreight is NZ's 16th largest company by market capitalisation and it is really exciting that they have committed to this large solar project.
The Westney Road system uses 1408 x Trina 300W DEG glass on glass monocrystalline modules. These are very efficient 60 cell modules - with module efficiency of 18.2%. One of the key drivers for Mainfreight choosing frameless modules was this longer, higher % performance warranty.
This system was the first in NZ to use SMA's new CORE1 inverter. This freestanding inverter is designed to be installed on rooftops - just like Westney Road - and has a built in DC isolator and six MPPT trackers.
