Darwin’s largest shopping centre, Casuarina Square, is on track to have the largest single solar rooftop system in Australia with the installation of more than 4,000 solar PV modules on its roof.

Installation of the $4.5 million 1.25 megawatt system is now underway and is due to be complete by the end of October.

The system will generate around 20% of Casuarina Square’s base building and common area electricity at no extra cost to the tenants.

The GPT Group, which manages Casuarina Square, already has solar systems in several of its properties, including the business park at 3 and 5 Murray Rose at Sydney Olympic Park, Rouse Hill Town Centre in Sydney and the Maribyrnong Homemaker Centre in Melbourne.
