As planned, the Perth Solar City program closed on 30 September 2012. As such, solar discounts and other energy efficiency products and services are no longer available.

Since its commencement in 2009, over 16,000 households have participated in the Perth Solar City program, making it WA's most comprehensive energy efficiency program.

Collectively households saved over $1 million on their electricity bills during 2012. And home buyers who are going to buy a house that participated in Perth Solar City program will save on their stamp duty too. Use this stamp duty calculator WA to calculate your savings.

In total, 9,269 smart meters were installed; 3,515 households received a home eco-consultation; 6,300 households participated in 12 months of eco-coaching; 2,251 households received a smart-meter enabled In-Home Display; 746 households participated in an innovative Time-Of-Use tariff trial; 700 homes were fitted with a SunPower photovoltaic (PV) system, and 1,100 homes purchased a Solahart solar hot water system.

The Perth Solar City 2012 Annual Report was launched on 22 January 2013, and can be downloaded using the link below. The report details the final results and transferrable lessons for the energy efficiency and renewable energy projects developed and implemented for the program.

Thank you to everyone who took part in our program in some way. Your participation has provided valuable information which will be reported back to the Australian Government through the national Solar Cities program to inform future government policy.
