Some 1.4 million of Australia's 7.8 million homes -- around one in five -- currently have solar power. During the day, solar panels generate large volumes of power that go unused in the home. This unused energy is exported to utilities who pay around 7c per kilowatt hour. At night, when families are home, power usage increases, and families purchase energy at four times their generation rate, with basic flat tariffs ranging between 25 to 28c per kilowatt hour.

Brisbane-based Redback Technologies is launching a second generation version of their smart hybrid inverter and a new family of grid tied inverters that the solar energy specialist says will help households and commercial users increase the percentage of solar power they self-consume, improving the pay back from solar panels and helping to reduce reliance on fossil based fuels.
