small generation unit STC calculator and the
solar water heater STC calculator reflect the current deeming periods. You can use these to calculate the number of certificates a system may be eligible for.
Under the Small-scale Renewable Energy Scheme, small-scale technology certificates are calculated based on:
The deeming period for solar PV systems, solar water heaters and air sourced heat pumps decreases by one year, every year until 2030. This will reduce the number of certificates that can be created for an eligible system. The table below provides further detail.
The table below presents the:
The number of eligible STCs listed on the
register of solar water heaters is based on calculated energy savings for solar water heaters over a 10-year period. The number of eligible STCs listed on the register will be multiplied by the multiplication factor that corresponds to the deeming period in years. This is then rounded down to the nearest whole number.
The Clean Energy Regulator will be closely monitoring installation dates during this time to ensure that the correct deeming period is applied. The provision of false and misleading information is an offence under the
Renewable Energy (Electricity) Act 2000. Where certificates have been improperly created, we will take enforcement and/or administrative activity that may include:
