Crown Melbourne complex recently commissioned Beon Energy Solutions to design and install a 300kw system, which is now in production.

It is the largest rooftop solar system in central Melbourne, overtaking the Queen Victoria Market (252kw) and North Melbourne Football Club (200kw).

Crown Melbourne engineering manager Jeremy Sampson said the environmental and financial benefits had made a compelling business case for solar.

“Each year more than 21 million people pass through the building. Open 24 hours a day, the Southbank venue’s energy costs are substantial,” said Sampson.

“The company was constantly on the hunt for energy conservation opportunities and had been looking at solar options for a while, and the business case for a solar installation made sense,” said Sampson.

“Crown chooses projects that are guaranteed to provide positive value, and it was the right decision to proceed.”

As part of the project, 923 photovoltaic panels were installed on top of Crown’s administration building on north-orientated 10-degree tilt frames.

“While similar panels are commonly installed on metal roofs, the concrete surface posed a new challenge for the installation team. Any fears of teething issues were quickly allayed,” said Sampson.

“The system also needed to integrate with Crown’s co-generation plant, which provides standby emergency power and heat capacity.”
