The Australian government has committed to achieving a range of renewable energy targets. To realise them, one of their initiatives is the Small-scale Renewable Energy Scheme.
This scheme gives households and businesses a discount on the purchase price of renewable energy systems (solar, wind and hydro), all with the aim of encouraging uptake. And that discount is called a Small-scale Technology Certificate (STC).
Think of an STC as a discount coupon on the upfront cost of your energy system, be it solar PV panels or solar hot water.
The most common way it works is for your installer to calculate how many STCs you’ll get based on the system you choose, and then apply that as a reduction on your purchase price. When it’s time to install, you assign your STCs to your installer and they trade them in for cash.
You can choose to sell your STCs yourself, but it’s a fairly complicated process, plus you won’t receive the upfront discount on your system.
Your magic STC number depends on a three things:
Basically the bigger the system, the bigger your STC number.
The sunnier your location, the greater your STC number as you’ll be able to produce more energy (you lucky Queenslanders!). You can see your STC number by postcode here.
The STC scheme ends in 2030. The number of STCs you get per kW of solar install decreases by one each year from 2017 (the deeming period). So if you installed yours in 2017, you get 14. If you install it in 2022, you get 9.
You then use this formula to calculate your STCs:
kW system x location x year of installation = No. of STCs
If you’re not keen on doing the maths yourself, this calculator will do it for you.
Systems that are eligible for STCs include:
There are a few other requirements surrounding paperwork, meeting Australian and New Zealand standards, and ensuring your system is listed on the Clean Energy Council’s approved list, so it’s important to familiarise yourself with those too.
We hope this information demystifies the process of calculating and applying STCs, and gives you a greater understanding of how your solar discount is determined. But if you’d like a bit more help, feel free to contact one of our Huglo solar specialists for a chat.

Solar Inverters are the unsung hero of your solar system. These devices turn your DC power into usable AC power for your home. This is what you need to know about the inverters Huglo Solar installs.
The easy part was deciding to go solar. The slightly trickier part is now choosing the right system for your needs. But we’ve got your back on that one.
There is a big difference between Product and Performance warranties of solar panels. Huglo Solar recommend you focus on the Product Warranty as this provides a better indicator of the quality of panels and the risk of defects.
