Under the Small-scale Renewable Energy Scheme, small-scale technology certificates are calculated based on:
- system location
- installation date, and
- if they are created over one or five years, or a single maximum deeming period.
The deeming period for solar PV systems decreases by one year, every year until 2030. This will reduce the number of certificates that can be created for an eligible system.
Solar PV Deeming Period in years
| Year solar (PV) system installed | Deeming Period in years |
|---|
| before 2016 | 15 |
| 2016 | 15 |
| 2017 | 14 |
| 2018 | 13 |
| 2019 | 12 |
| 2020 | 11 |
| 2021 | 10 |
| 2022 | 9 |
| 2023 | 8 |
| 2024 | 7 |
| 2025 | 6 |
| 2026 | 5 |
| 2027 | 4 |
| 2028 | 3 |
| 2029 | 2 |
| 2030 | 1 |
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:
- account, registration and or accreditation suspension
- enforceable undertakings to remedy breaches and improve compliance practices
- criminal or civil court proceedings, and
- surrender of certificates.
The
small generation unit STC calculator and the
solar water heater STC calculator reflect the current deeming periods and can be used to calculate the number of certificates applied until 2030.
