Solar Subsidy for your home in South Australia 2021 – How to calculate stcs and rebates.


Source: ABC News

In South Australia, we get plenty of sun all year-round. We typically get 7:36 hours of sunlight a day, and a total of 2774 hours of sunlight per year.

In every state in Australia, solar panels are worth buying no matter your energy consumption. South Australia has a strong rooftop PV industry, with about 1 in 3 households having solar panels. While there are many variables that impact the cost, savings and payback of solar panels, the upshot is that in Australia they are a good investment.

With government rebates and reducing solar panel costs, South Australian residents can get a solar panel system today without spending a fortune. This guide will provide you with detailed information on all the possible rebates you are entitled to as an Australian Solar consumer. Claiming STCs can be complicated, but it shouldn’t be. By reading our guide, you will get a good idea of the amount in rebates that you can get as well as learn how to claim them.

There are two kinds of rebates in South Australia: The State Government’s Solar Feed-in Tariff and Small-scale Technology Certificates. We explore what both of these rebates mean for South Australians, something that is quite important for those adopting solar for the first time.

What does stc stand for?

STCs are small-scale technology certificates that apply for residential solar installations. STCs are issued alongside qualifying solar power systems and solar panels. This can be used at a later date to withdraw the dollar equivalent that will be credited against your purchase. STC values change over time, and are affected by market conditions. As a result, so will how much cash back you can get. Note that these renewable technology certificates can also apply for commercial solar installations, known as LGCs.

STCs are eligible to be redeemed until 2030 January 1st, and decline in value over the subsequent years before then. That’s because the scheme was designed to phase out totally in 2030. For example, the value of an STC was $39.60 in April 2020, down to $38.25 as of 5th July 2021.

How does the solar subsidy in South Australia work?

To calculate the total amount of STCs applied to a system, you multiply the solar system size (kW) x Postcode Zone Rating x Deeming Period (years) = Number of STCs.

When calculating STCs, factors such as shading and efficiency losses are ignored when calculating the STC solar rebate.

When you purchase a solar PV system from Natural Technology Systems, we will have already discounted this value for you in your solar quote. That’s because we take over the hassle of registering and selling the STCs on the market from you. We give you a point of sale discount based on your STCs.

On the day of installation, you assign the STCs over to us, then we complete the registration of these certificates with the Renewable Energy Regulator on your behalf and eventually recoup their value. You don’t have to wait for this to happen, we do. You get an immediate deduction in cost.

Solar Subsidy FAQ

Is this really a rebate?

The program was previously referred to as the Solar Credits rebate, but in effect it is a subsidy offering up-front discount on the purchase of a solar power system.

Who is eligible for STCs?

The Australian solar credits scheme is open to any homeowner, business or community group. Even schools are also eligible.

Does it cover off-grid systems?

Yes, the solar credits program covers grid connected and off grid solar power systems. Further details about Solar Credits and off-grid solar power systems can be viewed here.

Does it cover Battery systems / hybrid systems?

A solar subsidy still applies for a battery system that is coupled with a solar pv system, but the energy storage itself would not be eligible for extra STCs.

Can I install the panels myself to get STCs?

No. The Clean Energy Regulator states that it is a requirement that only CEC accredited installers can sign off on STCs. Only then you are eligible for the rebate.

Are caravans, boats, sheds, motor homes and RVs eligible for STCs?

As long as the caravan, boat, shed or RV is your principle place of residence and has an address (such as a caravan park or marina berth), it will be eligible for STCs.
