Government Rebates and Incentives


Small-scale Technology Certificates (STCs)

Small-scale Technology Certificates are issued for small scale solar photovoltaic systems and other renewable energy systems, including hot water heat pumps. The number of certificates issued depends on the size, location and deeming period of the certificates. The certificates are a trading commodity and are traded on a market; hence fluctuate in value on a daily basis. The number of certificates you are eligible for vary.

As a STCs trader, The Energy Hub is able to discount your solar energy upfront for the value of your STCs. This means you save money straight away on the cost of installing solar!
Please note, the STCs price quoted on the The Energy Hub website is applicable to systems purchased from The Energy Hub. For those interested in selling their STCs to The Energy Hub, please contact us for a current price.

Find out more about STCs on the government information page.

Solar Credits Scheme

The Solar Credits Scheme is currently available to residential, rental and commercial properties. The Solar Credits Scheme multiplies the number of the STCs by a factor of 2 for the first 1.5kW of a system. Any additional kilowatt above 1.5kW receives a further STCs discount with no multiplying effect. The discount is determined by the number of STCs (once the Solar Credits Scheme is applied), multiplied by the value of the STCs at time of quotation.

For example

  • 2kW Grid-connect System installed in North Queensland
  • First 1.5kW = 31.095 STCs
  • Solar Credit Scheme Multiplier = (31.095 STCs x 2) = 62.19 STCs
  • Plus the extra 0.5kW of the system = 10.365 STCs + 62.19 STCs = 72.555 STCs
  • Discount on a 2kW System = (No. STCs x value of STCs) = 72.555 STCs x $27* = $1959

Total Discount = $1959 off a 2kW Photovoltaic Grid-Connect Solar System
(*Assuming STC market value = $27)

Changes To The Solar Credits Scheme

The Federal Minister for Climate Change and Energy Efficiency has announced that from July 1st 2011 the Solar Credits Scheme multiplier will reduce from 5 to 3 and will decrease by 1 each year thereafter until the year 2013. This reduction to the multiplier will significantly reduce the upfront discount you will receive off the installation of your photovoltaic grid-connect solar system.

Stand Alone Power Systems

Off Grid Power Systems are also eligible for the Solar Credits Scheme discount up to a size of 20kW. An off grid power system is defined by as being installed at least 1km from the nearest main-grid line or less than 1km from a main-grid line where the owner has provided written evidence from the local network service provider that the total cost of connecting the power to the main-grid is more than $30,000.

The Solar Credits Scheme multiplier will only apply to systems that have been installed prior to the annual STC cap being met of 250,000 STCs for the financial years of 2011 – 2013.
If the annual cap is equal or exceeded the Solar Credits multiplier immediately applies to only the first 1.5W of capacity installed. Generation from capacity above 1.5 kW will still be eligible for the 1:1 rate of STC creation.

Solar Bonus Scheme (Queensland)

The Solar Bonus Scheme provides a feed-in tariff for electricity generated by solar photovoltaic (PV) systems that is exported into the grid. This means your power bill will be credited with XX* for every kilowatt hour (kWh) that your grid connect system feeds back into the grid above your electricity demand at any time while your PV system is generating power.

Currently most households purchase electricity for XXper kWh (current as of January 2013) from their supplier. Any electricity generated by the grid connect system and used in the household will be free of charge.

The Solar Bonus Scheme encourages households to ensure minimal power is used during the day and encourages consumers to be energy conscious. By ensuring minimal power is used during the day, maximum benefit can be obtained from the solar system.

Families who are out during the day will ensure all lights and fans are off, all appliances are off at the power point, appliances like dishwashers and washing machines to be used early morning or evening to obtain the maximum power to be exported to the grid during the day.

An example of the daily power usage of a household of five compared to the power generated by a PV system is illustrated in the graph below. The bars in red indicate what power is being used by a household and the bars in green indicate the power being generated by the PV system. Whenever the green bars exceed the red bars, excess power is being exported into the electricity grid.
