In 2009, the federal government introduced the Solar Credits Scheme for solar power systems as a rebate incentive for people to invest in solar power.

Multiplier for Certificates for Renewable Energy
Installation Period Number of Multiplier
1 July 2011 to 30 June 2012 3
1 July 2012 to 31 December 2012 2
From 1 January 2013 1

As of the 1st of January 2013, the government reduced the Solar Credits Scheme from a multiplier of 2 down to 1. e.g. If you install a 1.5kW solar power system in Sydney after 1st January 2013, the system will create 31 STC’s for the installation of your solar system.


Small-scale technology certificates (STC’s), formerly known as REC’s are certificates created when you purchase your solar power system and it is installed by a CEC accredited installer. The number of STC’s created depends on the size of the system you install and where you live.

STC’s can be traded to receive a point of sale discount when purchasing your solar power system making it even more affordable. Solar Reaction Pty Ltd looks after all the paperwork required making it easier than ever to install solar power to your home. For more information on STC’s, visit the Clean Energy Regulator's website.


Australia has been divided into four zones based on levels of solar radiation (energy from the sun). The same sized solar power system installed in Melbourne or Hobart (Zone 4) will receive fewer STC’s than those installed in Sydney (Zone 3) or Darwin (Zone 2). This is because Melbourne and Hobart receive less solar radiation than cities like Sydney and Darwin.

Zones STC pricing

As STC’s are traded on a market, the value of the certificates fluctuates, just like shares. Its value can range from as low as $20 and up to $40 per STC. To find out the current STC pricing, visit Green Energy Trading.

Solar power and solar hot water

Solar power is different to solar hot water. Solar hot water uses the heat from the sun to heat the water inside the panel connector, whereas solar power from photovoltaic modules uses the energy from sunlight to generate electricity.

If you are thinking of installing solar power and you already have solar hot water, you are still eligible to receive a rebate for solar power because they are under different government incentive schemes.


To attract people to invest in renewable energy, the state governments are offering a feed-in tariff for the electricity generated from solar power or any other renewable source.

There are 2 types of feed-in tariffs: gross and net feed-in tariff.

Once your solar power system and the new meter(s) have been installed, any electricity exported to the electricity grid will appear on your electricity bill as credits.

The table below shows the current feed-in tariff rates for each state.

Current State Feed-In Tariff Rates

State  2.0 kW Avg. Daily Generation  Feed-In Tariff Maximum Size  End Date 
SA 8.4 kWh Net Export 25.8c/kWh First 45kWh daily Middle of 2016
