Rebates and Incentives

There are upfront rebates and incentives available for most renewable energy installations, including solar panels and battery storage systems.

Off-Grid Energy consultants will help you to understand what incentives you’re equipment is eligible for, calculate and maximise how much you will receive and process all the required paperwork.

Grid Connected Solar & Battery Systems - The Finer Detail on Expected Savings

Small Scale Technology Certificates

Eligible Customers: Off-Grid, Grid-Connected, Residential, Commercial

Small-scale Technology Certificates (STC’s – previously known as REC’s) are available and will help to offset the upfront cost of any renewable energy component in your system. These certificates are essentially carbon-offset shares, meaning that the more renewable energy that is installed, the more carbon is offset, and the more STCs it is eligible for and the larger your rebate will be.

A single STC equates to roughly 1 megawatt hour (MWh) of carbon intensive electricity that has been displaced over the life of your system.

This can typically equate to an upfront discount of between $1000 – $13,000 depending on the size of the solar array that is installed as part of your standalone system.

You can be paid your STCs in two ways. Assign your STCs to a registered agent such as Off-Grid Energy Australia, in exchange for an upfront discount when you purchase your solar PV system. (Most customers use this option). Or you can create the STCs yourself by finding a buyer and selling them in the Renewable Energy Certificate (REC) Registry.


Do I wait to receive my STC payment after the system installation?

No, Off-Grid Energy will deduct the STC value from your invoice at point of sale.
Due to the fluctuation of STC values, the final STC price may vary from the indicative value provided at contract acceptance to the actual STC value on installation day.


STC Deeming Period

Each year, the ‘deeming period’ (the amount of electricity generated over the course of its lifetime) will decline each year until 2030 when the scheme ends. 

  • 2022 = 9 years
  • 2023 = 8 years
  • 2024 = 7 years
  • 2025 = 6 years
  • 2026 = 5 years
  • 2027 = 4 years
  • 2028 = 3 years
  • 2029 = 2 years
  • 2030 = 1 year

Which is why you might see solar companies advertising the ‘decreasing rebate’ at the end of each year.


STC Eligibility Criteria

To be eligible for STCs, the installation must:

  • Have panels and inverter listed on the Clean Energy Council list of approved components
  • Meet Australian and New Zealand standards
  • Use a  Clean Energy Council accredited designer and installer and meet the  Clean Energy Council design and install guidelines​
  • Comply with all local, state, territory and federal requirements, including electrical safety, and
  • Be classified as small-scale, and a:
    • solar panel system that has a capacity of no more than 100 kW, and a total annual electricity output less than 250 MWh
    • wind system that has a capacity of no more than 10 kW, and a total annual electricity output of less than 25 MWh, or
    • hydro system that has a capacity of no more than 6.4 kW, and a total annual electricity output of less than 25 MWh.

PV system expansions can be eligible for STCs in certain circumstances. Although you may need to replace a number of the components of your system to be eligible. 


STC Zone Map

Each STC Zone attracts a different number of STCs for the amount of kWh’s produced. Zone 1 attracts the highest amount, and Zone 4 the lowest.
