*The Solar Homes and Communities Plan is a Federal Government initiative which started out as the Photovoltaic Rebate Program in 2000. The program offered $4,000 rebates to households to install solar panels, and ran until November 2007. In that time the program helped to install 10,000 solar systems and was receiving an average of 153 applications per week. Solar panels use light energy or photons from the sun to generate electricity.
The Photovoltaic Rebate Program was changed in November 2007 to the Solar Homes and Communities Plan, as part of the Rudd government’s election commitments. The program was allocated $150 million to provide increased rebates of up to $8,000 to 15,000 homes over five years.
In May 2008 a means test was placed on the solar panel rebate. Nationally, the number of applications for the rebate grew from 420 per week in May 2008 to approximately 6,043 in May 2009*.

On 9 June 2009 the federal government replaced the Solar Homes and Communities Plan with the Solar Credits program. Households and businesses that install eligible small scale solar photovoltaic, wind and hydro electricity systems may be able to receive extra renewable energy certificates. These will assist with the upfront costs of installing the systems and is not subject to means testing.
