Financial Incentives: STC rebate explained

Solar PV systems attract financial incentives based on their size and location as legislated in the RET scheme (Renewable Energy Target). The scheme is available for both commercial and residential customers. Systems up to 100 kW qualify for Small-scale Technology Certificates (STCs), whereas systems above 100 kW need to be registered as “power stations” to receive Large-scale Technology Certificates (LGCs) on a quarterly or yearly basis – depending on their electricity output.

How much financial support do I get?

STC rebate calculatorThe value of the STCs varies depending on supply and demand in the market, just like a stock or commodity. The amount of STCs or the STC entitlement also depends on the geographical location of the installation. For example, the entire area around Perth including Mandurah, Bunbury, Margaret River and in the North beyond Geraldton is classified as Zone 3. Less sunny places, such as Melbourne, are in Zone 2 and receive slightly fewer STCs.

At the time of writing, STCs are worth $38 per certificate. By multiplying the STC entitlement with the STC price, the total amount of STC rebate can be calculated.

DNX Energy handles all the paperwork required, and our clients are able to pay a reduced amount for their solar systems.
