Project-specific eligibility
Small-scale technology certificates
Solar support for eligible installations.
Certificate eligibility and value depend on your system, installation date, location and applicable scheme requirements.
Reduce project cost
Applicable STCs can contribute toward reducing the effective upfront cost of an eligible solar installation.
Project-specific value
Certificate entitlement and market value can vary according to the installation and applicable scheme conditions.
Designed around the project.
System size, site location and installation timing can influence STCs.
Understanding the scheme
What are Small-scale Technology Certificates?
STCs are certificates associated with eligible small-scale renewable-energy installations under Australia’s renewable-energy framework.
Homeowners and small businesses installing eligible new solar systems may be able to use the value of applicable STCs to help offset the cost of purchasing and installing their system.
The number of certificates associated with a project depends on several factors, which means the benefit should be assessed as part of the actual system design rather than assumed in advance.
Speak with SolaringWhat affects your STCs?
The certificate amount is project-specific.
The STCs associated with an eligible installation can be influenced by the location of the system, when it is installed and the applicable deeming period.
System location
Geographic location can affect the certificate calculation associated with an eligible solar system.
Installation date
The date your system is installed can influence the certificate entitlement under the applicable scheme.
Deeming period
The applicable remaining deeming period can affect the number of certificates created by an eligible installation.
Illustrative STC example
6.66kW
A simple example showing how certificates can contribute
toward the effective cost of an eligible solar installation.
How STC value can add up.
For illustration, a 6.66kW solar system installed in South Australia in 2023 was estimated at approximately 72 STCs.
At an illustrative certificate value of $37 each, 72 STCs would represent approximately $2,664 in certificate value.
STC entitlement and certificate market prices can change.
Your actual benefit will depend on the system, installation
date, location and applicable scheme conditions.
How Solaring can help
Start with the right solar system.
The system should first suit your property and energy requirements. Applicable STCs can then be considered as part of the overall project.
Assess your property
We review your electricity use, roof, property conditions and future energy requirements.
Design the system
Solar capacity and equipment are selected around the site and how your property uses energy.
Review STC eligibility
Applicable certificate eligibility can be assessed against the proposed system and installation.
Receive your proposal
We prepare the recommended equipment, installation scope and relevant project information for review.
Check your options
Planning a new solar installation?
Tell us about your property, electricity usage and what you want your solar system to achieve. We can help assess an appropriate system and discuss applicable STCs as part of the project.
