The company celebrated its $2.7 million solar project on Thursday – which it claims is the largest single rooftop solar system in Australia.

The system comprises of 5,480 solar panels across a roof area of approximately 27,000 square metres.

Since it was switched on between April and June, it has generated over 73,090kWh of energy for the centre, with the system on track to meet its target of 2,773,070 kWh per year – enough to power roughly 300 homes.

It has also cut peak electricity demand by 29 per cent and grid supplied electricity by 46.3 per cent.

Stockland group executive and CEO commercial property Louise Mason said the idea was to create clean, secure and affordable energy.

“We chose to incorporate a number of innovative green principles into the $414 million redevelopment, including free electric vehicle charging facilities, large scale rooftop solar and energy efficient lighting and air conditioning,” she said.

“We also considered sustainability beyond the rating tools, incorporating a number of important community facilities and amenities in this redevelopment and we’re extremely proud to have Stockland Green Hills receive a 5 Star Green Star – Design (Retail Centre) certified rating from the Green Building Council of Australia earlier this year.”
