How does STC trading work? A Solar Installers and Retailers Guide to STCs

The Federal Government created the Small-scale Technology Certificate (STC) trading market in 2001 to encourage consumers and small businesses to install renewable energy systems. It does this by setting a requirement for big polluters to buy a certain percentage of energy each year from renewable energy sources.

There’s no denying that these STCs have been a critical part of the solar boom in the last decade. By creating an upfront discount, they’ve decreased the cost of installation by an average of $500-$600 per kW. However, the additional paperwork could be challenging when you first start selling on your own. You just want to get back to doing what you do best, designing and installing rooftop solar PV systems. So to help you simplify your business administration, we’ve created this guide to help solar installers on how to manage your STCs.

In this article, we cover:

• how the small-scale renewable energy scheme works
• how to calculate STCs

STC eligibility requirements

Stc legal paperwork, how to become a rec agent, historical stc prices.

• and how to answer Common STC questions from consumers.

How the Small-scale Renewable Energy Scheme works

The Small-scale Renewable Energy Scheme, or SRES, is the name of the STC market.

• The Federal Government creates Renewable Energy Certificates. STCs are awarded to solar projects below 100kW.
• The government awards your customers (the homeowners) STCs, when they purchase solar PV systems from you, .
• Your customer signs the rights to the STCs to you (optional).
• The STCs are registered and sold on the market. This is typically done via a specialist STC broker. The total value of the STCs allow you to offset the upfront cost of the solar system.
• The STCs are then sold to fossil fuel generators and other large polluters.

How to calculate STCs

The formula used to calculate the number of STCs each solar system should be awarded is quite simple. First, multiply the DC capacity of your customer’s solar panels, the years left in the SRES on date of install, and the rating given to your customer’s STC region. After that, round down the result as the CER does not award partial STCs.

For example: 5 (kW) x 13 (years) x 1.382 (zone 3) = 82.92 = 82 STCs

Assuming your STCs can be traded for $35 each, this is a saving of $2,870.00.

NOTE: The number of years in the deeming period decreases over time was designed to incentivise consumers to get solar sooner, rather than later.

Zone multipliers

• Zone 1 – 1.622 multiplier
• Zone 2 – 1.536 multiplier
• Zone 3 – 1.382 multiplier
• Zone 4 – 1.185 multiplier

The eligibility requirements cover five facets, and they are:

• you and your company’s qualifications
• the solar project’s size
• the solar project’s adherence to safety and quality standards;
• the certificate creation date
• and protecting your customer after the install.

You and your company’s qualifications.

The solar system must be designed and installed by CEC accredited technicians to be eligible for STCs.

Working on Grid-connect or Stand-Alone systems requires separate accreditations. Depending on your business needs and where you choose to take your career you can get accreditations for both design and installation. You must hold an unrestricted electrical license to apply for any Install accreditations.

The solar design and installation.

The output capacity of STC projects is limited to 100kW. This refers to the solar panel ‘rated’ output, and not the inverter. Over this size, LGCs are the relevant Renewable Energy Certificate.

The only solar panels and inverters which can be installed under the SRES are those approved for use by the Clean Energy Council at time of STC creation. If a product has been de-listed between installation and attempted creation of STCs, the system is no longer eligible.

The design and installation follow the relevant CEC guideline:

• Grid-Connected Solar PV Systems: Install and Supervise Guidelines for Accredited Installers
• Grid-Connected Solar PV Systems: No Battery Storage, Design Guidelines for Accredited Installers
• 30-100kW Grid-Connected Solar PV Systems: No Battery Storage, Design Guidelines for Accredited Installers

Your installation complies with the service and installation rules for your state

• ACT: ActewAGL Service and Installation Rules
• NSW: NSW Trade and Investment: Energy Supply Industry Service and Installation Rules
• NT: PowerWater Power Network Policy Installation Rules and Power Networks Service Rules
• SA: SA Power Networks Service and Installation Rules
• TAS: Tas Networks Service and Installation Rules
• QLD: Queensland Electricity Connection & Metering Manual
• VIC: Victorian Service and Installation Rules
• WA: WA Department of Commerce Electrical Requirements

Your installation complies with the electricity safety Acts for your state.

The design and installation follow the Australian Standards.

• AS/NZS 3000:2018, Wiring rules
• AS 4777.2:2016, Grid connection of energy systems via inverters
• AS/NZS 5033:2014, Installation and safety requirements for photovoltaic arrays
• AS/NZS 1768:2007, Lightning protection
• AS/NZS 1170.2:2007, Structural design actions, Part 2: Wind actions
• AS/NZS 4509.1:2009, Stand-alone power systems, Part 1: Safety and installation (for off-grid systems)
• AS 4086.2:1997, Secondary batteries for use with stand-alone power systems, Part 2: Installation and maintenance. (for battery systems)
• AS 5139:2019, Electrical Installations—Safety of battery systems for use with power conversion equipment (for battery systems)

Certificate creation date.

The STC certificates can be created no later than 12 months post-install.

Post-install.

The STC assignment form is completed and submitted to the party who registers the STCs. This is either you or your chosen trader. Then, certificates of compliance are given to the customer with a copy retained by yourself.

These include:

• a certificate to confirm the system meets all relevant Australian Standards, and all local, state or territory requirements
• an on-site verification statement by the system owner that the accredited installer or supervisor has attended the system installation
• an on-site verification statement by installers
• a certificate to confirm your company has at least $5 million public liability insurance
• a certificate of electrical safety
• and an engineering certificate from your solar panel mounting bracket supplier stating that the array frame is certified to AS1170.2 for their location.

Replacement System STC Eligibility

If you are replacing an entire system, the new system is eligible for STCs. If you are replacing panels, the system is not eligible for STCs for the new panels. The reason: at least one major component (i.e.; panel or inverter) has been used previously to claim small-scale technology certificates for the same project.

Solar Panel Validation Initiative

To prevent fraud, industry players and manufacturers have coordinated to create solar panels validation apps under the Solar Panel Validation Initiative. This program is designed to discourage unscrupulous manufacturers and suppliers from selling fake solar panels.

This task is an optional extra that speeds up the CER’s mandatory pre-sale STC audit. Without solar panel validation, it could take up to 4 weeks. With solar panel validation, auditing is typically around 48 hours.

Participating in the STC market

The easiest way is to have STC traders sell AND register your STCs for you. Alternately, you can register and have the traders sell for you, or even do all the registering and selling yourself. If you’re interested to know how to do it all yourself, we explain the necessary steps in the How to become a REC agent section below.

Traders register and sell your unregistered STCs

This is the most common choice of small to mid-size installers and retailers. It saves time and creates a more predictable cash-flow.

Traders will buy your unregistered STCs same-day for a typical cost of $1 per STC. This looks like a $1 lower unregistered STC price and gives you faster access to cash. This price usually ranges from $32 to $38 per STC, depending on market conditions.

That price will always be a little lower than the current STC spot price. For their business to operate, they need to have some margin when they aggregate and sell the STCs themselves - a small price to pay for convenience and cash-flow.

Registered STCs

Large retailers often favour this option as the two-day to four-week registration timeline won’t impact cash-flow at your scale. Having access to large quantities of STCs also allows you to trade at the 5,000 minimum market parcel size at the spot price.

You register your STCs yourself and traders sell them

To register STCs yourself, you have to become a REC agent first. This application process can take many months.

Additionally, because the CER audits and validates all STCs before they can be sold, it adds a couple of days to your process time.

After you create your first 250 STCs in the REC registry, which are free, each extra certificate costs 47 cents to create. That is offset by traders offering you an average of $1 more for your registered STC.

Once you have negotiated a price with the traders, you transfer ownership through the REC registry.

Registering and selling the STCs yourself

After you create the STCs on the REC Registry, you have two options. You can then place them on the STC Clearing House or contact the big polluters to sell them directly.

On the Clearing House, you’ll get a guaranteed price of $40 (excl. GST). Your STCs will get added to the back of the queue as sales are processed on a first in first served basis. When they are sold, you’ll get an email, and the money should arrive in your account within three working days.

It can take weeks and months for STCs to be bought from the Clearing House because it’s the highest price. Unless the spot price is around and over $40, there is no financial incentive for the big polluters to buy from there.

Either way, to create and sell STCs, the following paperwork is required. They must be ready to give to the Clean Energy Regulator during the audit process if requested. I have attached links to the Clean Energy Regulator’s templates which they strongly encourage you to personalise for your company.

• The STC assignment form
• The on-site verification statement by the system owner
• The on-site verification statement by the accredited designer and installer
• Written statements that say you (included in the STC assignment form template): are accredited by the Clean Energy Council; have installed a system that meets the Australian Standards; have at least $5 million in public liability insurance; have installed the system according to local and state rules, and have completed the installation

List of STC traders

Traders offer a variety of options to help you with STCs registration and selling. These include online and paper (scanned) submissions, built-in solar panel validation, payment for selling your STCs to them same-day, within three business days, and even payment after the audit. Some have online apps, but all of them have their own STC assignment form template.

I’ve listed the specialist STC traders below to help you save time working out which one is right for you.

• Trade in Green
• Green Energy Trading
• RET Australia
• Sol Distribution
• One Stop Warehouse
• Powerark Solar
• Habitat Energy Systems
• Emerging Energy
• REC Traders
• REC Services

To register your STCs yourself, you’ll need to become a REC agent.

First, create an account on the Clean Energy Regulator Portal . After that, the Clean Energy Regulator asks that you complete SRES Smart, which aims to check that you know your obligations under the scheme as an installer.

You’ll need to pass every test with a score of at least 80% within five attempts.

Then you make an online application through the REC Registry. It may take up to 6 weeks for the CER to assess your application and get back to you.

If your application has been successful, you then ‘Upgrade’ your account in the settings to get access to the STC Clearing House. As a REC Agent, you can now register STCs.

If you’re interested in some historical STC prices, Demand Manager has a good overview of the last 12 months.

The easiest way to explain STCs to your customers

“The Solar PV system creates STCs. These belong to the owner of the solar system, you. So that you don’t need to deal with the whole STC creation and selling process, you transfer the rights to the STCs to me for a discount on the system price and I sell them for you.

Four factors determine the size of the STC financial incentive.

• the kW size of the solar system
• years till 2030 - the end of the SRES STC scheme
• the postcode you live in (your STC zone)
• the per STC price”

Common questions customers ask

Does it top out.

Yes. As a program for small-scale solar renewable energy installs, the maximum output capacity is 100kW. For renewable projects above 100kW, large-scale generation certificates (LGCs) are awarded.

Are off-grid solar PV projects included?

Yes, it also covers off-grid.

Are there income requirements?

No, the STC solar incentive program is not means-tested.

Who is the STC program for?

It’s for any solar PV project no matter the type of owner - homes, small businesses, schools, community groups.

What about batteries?

The STC solar incentive is not intended to cover energy storage because it doesn’t directly create additional solar energy production.

What about caravans, boats, houseboats, motor homes, and RVs?

It can apply to portable housing as long as it’s your primary place of residence.

Is this a rebate?

Despite how it appears, the STC ‘rebate’ is actually not a rebate. The STCs are a federal government incentive structure.

What is the STC rebate?

STCs are Australian Federal government issued certificates designed to reward the installation of small-scale renewable power generators. The number of STCs that are generated depend on the total kW size of the solar system, the number of years remaining in the deeming period and the multiplier factor that depends on the location of install."

How are STCs calculated?

Do you have to be on the grid to earn stc’s.

No, you don’t need to be connected to the grid to generate STCs

Create small-scale technology certificates

Creating and selling small-scale technology certificates (STCs) can be complicated. To make things simpler, most people assign the right to create STCs to a registered agent in exchange for an upfront discount on the system's purchase price.

If you're an agent or a system owner who is creating STCs themselves, you must follow these steps to create your certificates.

Before you create STCs

• Check the system is eligible
• Confirm you're the system owner or have the right to create certificates for the system
• Check your sales contract to ensure STCs haven't already been created for the system
• Ensure you have all the required documents and evidence
• Ensure documents are signed by the relevant parties, including the installer, designer, retailer and owner (if required)
• Select the deeming period and calculate certificate entitlements
• Create the certificates within 12 months of the installation date

Avoid disputes

Check your contract with your registered agent to avoid disputes.

Creating STCs

Certificates are created in the REC Registry .

Before creating STCs, ensure you have:

• the correct REC Registry account type
• all required documents ready to submit with your claim.

REC Registry account

If you're the system owner, you must create a ' registered person ' account in REC Registry.

If you're an agent, you must have a ' registered agent ' account. You must also have the STCs assigned to your account.

Required documents

Use our guides to ensure you have all required documents before creating STCs.

• Small generation units (solar PV, wind and hydro systems) 
• Solar water heaters 

To create STCs, you need to have certain documentation. The documents you need to provide depend on the system.

All required documents must be completed and signed before creating STCs.

You can upload the documents in the REC Registry when you submit your STC application. This will help reduce processing timeframes.

We can request you provide the required documents for up to 5 years from the date of creation. You must provide the documents if requested, even if the claim is already approved. 

If you don't provide complete documentation, we may:

• fail the STC claim
• issue a warning or take other compliance action
• request you to surrender STCs
• suspend you from participating
• review your fit and proper person status
• bring civil or criminal charges.

Registered agents Show

If you're a registered agent, you also need to provide an STC assignment form. The form needs to include a declaration that the system owner assigned the right to create STCs to you.

You can use our example STC assignment form as a guide.

Make sure the legal entity name in your STC assignment form matches your REC Registry account name.

You can also provide more information to support STC claims, including:

• rates notices
• contract information.

Make sure you check the reliability and accuracy of the information you provide. For example, that installer documents confirm the authenticity of an installer's declarations. You can customise your documents to include explanations, company logos and other features.

Multiple installations at one address

When you create certificates, it's important to provide all address details in the REC Registry. This ensures we can accurately assess your application as quick as possible.

For 2 or more installations at the same address, provide detailed information for us to locate and separate the systems. If you're unsure, add as many details to describe how to get to the property and each system.

If you need help, use our guides for collecting mandatory information:

• Small generation units (solar PV, wind and hydro systems)

Validating STCs

We audit certificates to ensure they are valid before we register them.

Validation will usually take 4 to 6 weeks. It may take longer if:

• you don't provide complete or correct documentation
• we identify a compliance issue.

We may fail certificates if:

• information provided is incorrect, invalid or duplicated
• you provide incomplete documents
• not eligible
• not classified as complete
• doesn't meet Solar Accreditation Australia 's designer and installer guidelines.

If you provided incorrect information in your claim, email [email protected] .

Registration fees

After we've validated your STCs, they appear as 'pending registration' in the REC Registry.

You need to pay fees to finalise registration. The first 250 certificates you create are free. Once you exceed the 250, fees will apply to all created certificates. This includes the first 250 certificates.

Fees per certificate:

• 47c for small generation units
• 8c for solar water heaters

If fees apply, you can pay them in the REC Registry .

Once registered, certificates will appear as registered under 'summary holdings'.

Re-creating STCs

We will let you know if we fail your certificates. You must subscribe to get these notices . Make sure any users you want to receive the notifications have signed up.

You may re-create the certificates if:

• the failure notification tells you to
• the errors were corrected
• the system is eligible
• the system installation was less than 12 months ago.

If your failure notification states you may not recreate, contact [email protected] before recreating.

How to re-create STCs

If we failed your STC claim and you would like to recreate, you must:

• correct all details listed in the original failure reason
• enter the failed accreditation code and add a note detailing why we failed the claim.

Improperly created certificates

Improperly creating certificates is a criminal offence under section 24 of the Renewable Energy (Electricity) Act 2000 . STCs found to be improperly created may result in referral for prosecution.

Trading STCs

After creating and registering your certificates, you can trade your STCs in the open market or the STC clearing house.

STC Program – The Solar Rebate That Is Not Officially a Rebate

STC program is the abbreviation of Small-scale Technology Certificate. STC is a government program that gives financial incentives issued with qualifying solar power systems and solar panels. This can be redeemed as a dollar value that is deducted from the cost of the solar system. The value of STC can be varied depending upon the market conditions.

What Is The STC Program?

Reduce upfront cost, criteria for claiming the financial incentive, how much is the stc rebate, how did the solar rebate work, why you should get quotes for solar sooner, how is stc rebate calculated, who can claim stcs, what is an stc assignment form, how do i claim stcs, how much is the solar rebate in wa.

The STC program comes under the solar credits program which says every megawatt-hour of qualifying energy generation is eligible to get Renewable Energy Certificates (RECs). These certificates can be split into two types: small-scale technology certificates and large-scale generation certificates (LGCs). STCs are the ones applicable to residential solar installations.

The government says it cannot be referred a solar rebate. The clean energy regulator website says that under the Small-scale Renewable Energy Scheme, the cost reduction in your solar panel is not a rebate. You will not be eligible for any Government-based financial compensation at the completion of any process relating to STCs. This only means the reduction in solar system price you are getting is not coming from the government.

You can get the benefit of this program while purchasing a solar power system from any reputed solar installers. Probably the installer discounts the STC value for you in your solar quote. They will take over the hassle of registering and selling STCs from you.

Read more about renewable power incentives given by the Australian government

If you buy a solar energy system now, it is subsidized by the government scheme worth around $650 per kW installed. For a typical 5kW system that cost reduction will be about $3250. This cost reduction will be applied at the point of sale.

The solar rebate started to reduce one fifteenth every year bases on the current legislation. It started in 2017 and it will gradually reduce until 2032 when the reduction will end up at zero.

If the demand for solar panels gets increased the value of the rebate will go down with STC price. The STC price can be varied between $0 and $40. This means the maximum value of STC set by law is $40.

Most of the owners are assigning a registered agent to create their small-scale technology certificates. But you have the option to create and trade the certificates by yourself. To claim your certificates, you need to follow the steps given here.

• Determine the eligibility of the solar power system or other small-scale renewable energy systems to be installed.
• Calculate the number of STCs to claim for your system.
• Obtain and complete the proper compliance paperwork.
• Create an account in the REC registry that includes verifying your identity and an assessment as a fit and proper person
• Creating STCs in the REC Registry within 12 months of the installation date.
• Wait for the Clean Energy Regulator to validate the certificates
• Find a buyer for the STCs or place them in the STC clearing house queue for sale.

Currently, the value of the solar rebate is about $38 per STC. It translates into a solar rebate of $525 per kW installed. As the STCs are traded in the open market it is exposed to market fluctuations. The historic low price of STCs has fallen into is $17. But still, the rebate will be worth around $221 per kW installed.

STCs are issued with eligible solar PV systems and solar panels and their dollar value can be redeemed which is usually deducted from the cost of the solar system. Most of the accredited solar installers take over the hassle of registering and selling STCs on the market from you and give the point-of-sale discount based on your STCs.

You can assign the certificates to the solar system installing agency will complete the registration process with the Renewable Energy Regulator on your behalf. But you don’t have to wait for that and will get an immediate cost reduction for the solar panel installation.

The amount you get can from this program is based on 3 factors:

• Dollar value of STC
• Zoning:Australia is divided into separate zones based on how much solar energy can be generated by the panels in a given area. You can see your zone by using the postal code.

See the Postcode zone ratings and postcode zones for solar panel systems given on the Clean Energy Regulator website to check your zone.

Each zone has a particular rating number which is used for the calculation of the number STCs the system eligible for. Those ratings are:

Zone 1 – 1.622 rating Zone 2 – 1.536 rating Zone 3 – 1.382 rating Zone 4 – 1.185 rating

• The deeming period: Since the solar rebate is gradually reducing one fifteenth every year until it gets completely ended, the deeming period will reduce each year.

Here are the approximate values of financial incentives for a 6.6kW solar energy system based on the $38 STC price:

Zone 1 – $4066

Zone 2 – $3852

Zone 3 – $3466

Zone 4 – $2971

As already mentioned, the amount of solar rebate can be varied according to the current market price of STC. Now the dollar value of STC is about $38 and the rebate will be worth around $525 per kW installed. When there is a high demand for solar panel installation, a lot of STCs will be created. As the supply of STC increases, the demand decreases and therefore the STC price and subsidy gets reduced.

Currently, a 6.6kW solar system is eligible for a rebate of $3465 (6.6kW x $525 = $3465). If the demand for solar panels increased too much, that can cause the STC price to drop. This means if you get quotes for solar now, you can get the rebate based on the current STC price.

The renewable energy certificates are introduced to attracts people to have renewable energy systems. They can also buy the right to other people’s energy systems in the form of RECs. The Small-scale Technology Certificate is a special type of REC. The value of STC can be redeemed as its dollar value. Most likely the installer will take care of the STC registration and other hassle related to it and you will get a reduction in cost during installation.

To calculate the rebate, you need to find out the number of Small-scale Technology Certificate your system eligible for. This can be calculated by the following equation?

Solar system size (kW) x Zone Rating x Deeming Period = Number of STCs

Then to find the solar rebate use the formula given below.

Number of STCs x Dollar value of an STC in the market = Amount of subsidy

The solar incentive program is open to a large group of people. Homeowners, small businesses, and community groups are all eligible for the program. The only eligibility criteria are:

• Your solar PV system should be less than 100kW.
• The system should be designed and installed by Clean Energy Council accredited professionals.
• Only use the solar panels  and inverter that are approved to use in Australia by the Clean Energy Council.

The renewable energy system owners must complete the STC assignment form to assign the certificates to an agent in exchange for a financial incentive. The form can be completed after the system installation is complete.

Commonly, the homeowners will assign the solar installer to create their small-scale technology certificates. You can ask a residential solar installer whether can manage the procedures to claim the STC solar rebate. But you can create and trade the STCs by yourself. The steps that need to be followed to claim by yourself have been explained above.

For 2020, the solar rebate value in Western Australia (WA) was $814 which translates into 22 STCs for a 1.5kW system. If you have a 2kW system, the incentive will be about $1110 or 30 STCs. All these estimates are calculated based on the $37 STC value.

Small-Scale Technology Certificates (STC) Compliance Update

Stc compliance process update – 01 april 2022.

From the 1st of April, several changes have been implemented into the compliance process for Solar STCs. These changes directly affect solar installers and designers, agents and retailers.

This set of changes has been brought into effect under the Renewable Energy (Electricity) Amendment Regulations 2021. There are a series of changes that will unroll throughout 2022. The aim of the reforms is to strengthen the compliance requirements to create a sector with greater integrity, ultimately decreasing the risk of fraudulent STC claims.

What has changed?

1. the stc assignment form and written statement requirements.

An STC claim must have written statements from the associated retailer, designer and installer. 

There is a sample form found here that will assist in the development of these forms for your STC claims. 

The Clean Energy Regulator (CER) recommends that a witness signature should be incorporated into the forms. Despite not being mandatory, it assists in providing further assurance of the validity of the STC claim to the regulator. 

The written statement can only be completed once the solar system has been installed and energised. A copy of the form must be provided to the owner of the solar system, and the registered agent who will create the STCs.

2. Invoice Evidence

Under these reforms, the regulator may request a copy of the invoice proving the solar system is meeting the requirements as per the contract.

3. Physical Site Attendance

Installers must have evidence proving their physical site attendance (in either a supervising or physical installation role). This requirement has been in place since 2013, and with the April 1st changes documentation in the form of a written statement will provide further evidence.

Three check points are required for each site:

• The job set-up
• Mid-installation check up
• Testing and commissioning

The evidence can be a geotagged photo at each stage. If the installation spans multiple days or weeks, the installer is advised to supply sufficient notes to the registered agent to be submitted with the STC claim.

4. STC Sign Offs per Day

An accredited installer can sign off on 2 complete installations in one day and be eligible for STCs.

5. Bulk Uploads and Information Requirements

The requirements for bulk upload of STCs, and the information required to claim STCs for Small Generation Units have also been updated. The new information can be found here.

6. Fraudulent Activity

The new regulations will allow the CER to declare an individual designer or installer ineligible to participate in the SRES, as opposed to a company. A declaration of ineligibility can last for up to 3 years.

For any further information or for questions you may have, please contact our SRES team at [email protected]

Small Scale Technology Certificates (STC's)

If you have installed a solar system in your home, you’re probably aware of the Small-scale Technology Certificates (STCs) scheme. But if you haven’t had solar panels installed yet, or if you’re thinking about getting them but not sure how to go about it, there are a few things you need to know about STCs first.

This article will take an in-depth look at small-scale technology certificates and why they benefit Australian homes and businesses.

What is a Small Scale Technology Certificates (STC)?

The Australian Government has established a voluntary scheme that allows companies to generate clean energy through small-scale renewable technologies like solar panels and wind turbines. As part of this scheme, they are awarded certificates for each unit of electricity produced from their renewable energy source, known as Small-scale Technology Certificates (STCs).

STCs are the Australian Government’s way of assisting with the development of new technologies in the renewable energy sector. These are used to help reduce CO2 emissions from electricity generation. They can be traded between businesses, allowing them to lower their carbon footprint, and your company can also use them to meet mandatory requirements.

You can claim an STC for any eligible renewable energy technology that generates electricity. The more STCs you have, the more your business qualifies for tax incentives and other rebates.

How do STC's work?

STCs are issued to solar power system owners by the Clean Energy Regulator based on how much electricity they generate. These tradable certificates can then be sold on an open market to people who want to use them for their installations or energy suppliers as part of their renewable energy portfolio standards obligations.

An STC represents one-megawatt hour (MWh) of eligible renewable electricity from an accredited generator registered with the Clean Energy Regulator. When you buy STCs, you’re supporting local businesses that have invested in clean energy technology and helping reduce your carbon footprint.

STC prices are determined by market demand when you sell your certificate. The value of your certificate will depend on where you live and whether there is more supply than demand at that time. With more demand than supply, selling your certificate becomes easier as buyers pay more to get hold of them.

Who can create STC's?

Developers can create STCs by generating renewable energy. It includes solar photovoltaic (PV), wind and hydroelectricity generators, or using biomass to produce heat or power. You can buy them from a developer as an incentive for making renewable energy.

You can also sell your entitlements directly to someone who wants them, such as retailers selling green energy options to customers. At the same time, they continue to supply regular grid power through their existing contracts with the retailers’ suppliers or generators with surplus capacity looking for ways of monetising their assets while managing peak demand and avoiding costly investment in extra infrastructure.

How much are stc's worth.

The Clean Energy Regulator sets the value of each STC based on how much your clean energy project saved carbon dioxide. When you buy an STC, it’s like buying a right to pollute, and part of your money goes towards paying for cleaner air in Australia.

For example, if there’s a 10% premium on the wholesale electricity market price of $100/MWh and you generate 100kWh of electricity that year, then your STC entitlement would be worth $10kWh x 10% = $1kW, for which you could sell each certificate at auction or privately with another party.

Can I use an STC on a small-scale renewable energy system if I rent my home?

You can claim STCs for small-scale renewable energy systems if you rent your home or lease it. However, the STC will be issued in the property owner’s name. In this situation, you need to ensure that your landlord knows what you’re doing so they don’t object.

Are there time limits for when small-scale renewable energy systems can be installed?

If you purchase a small-scale renewable energy system, such as solar system or a wind turbine, and install it within 12 months, you can claim STCs for that system. If you buy the components for your renewable energy technology and have them installed later, but within 12 months of purchase, STC claims cannot be made for those items.

Are there other rules about claiming STCs for buying or installing a small-scale renewable energy system?

• STCs can only be used for a small-scale renewable energy system. So, if you want to claim the STC for your gas hot water system, you won’t be able to do so.
• You must buy or install the system before claiming STCs. In other words, if someone else buys a solar hot water system and then installs it on your roof and claims the rebate, this isn’t allowed under current rules.
• Claiming STC needs to happen within 12 months of installing the system from when all parts are in place.

Can the Clean Energy Regulator revoke an STC from me if it turns out my system isn't eligible for STCs after all?

An STC can be revoked if it is found invalid or discovered that your installation was not eligible for an STC in the first place. If your system has already been approved and an STC issued, revocation would only occur after the Clean Energy Regulator audit your system.

Who are eligible for rebates when installing solar panels?

All homes in Australia are eligible for rebates when installing solar panels. The refund amount depends on the size of the solar panel system and is based on its STC value. In most cases, you will pay a discounted cost for your solar system, and it is simply a matter of waiting until you receive your rebate from an electricity retailer, which may take up to 6 months.

Solar panel systems must be installed by licensed installers registered with ARENA (Australian Renewable Energy Agency) or by accredited installers listed on the Clean Energy Council website as having passed a skills assessment test in solar installation. Australian Energy Upgrades is a proud Clean Energy Council Approved Solar Retailer.

What are the benefits of STCs?

There are several benefits associated with using small-scale technology certificates.

Financial savings and rebates

STCs can be sold, bought and traded. They are a form of carbon credits that can offset carbon emissions by investing in renewable energy projects. You could use the STC to offset the cost of solar panels or other small-scale technologies like bio-gas generators, rainwater tanks and heat pumps.

Y ou can save money by utilising solar energy.

Solar technology is an intelligent choice for reducing your electricity bill and saving money, reducing your reliance on the grid. It’s also an excellent investment in the future of our planet. It helps reduce carbon emissions and creates clean energy and jobs for local people.

Clean energy source

Renewable energy is a clean, renewable, and sustainable fuel source that reduces reliance on fossil fuels. Using clean energy sources also lowers carbon emissions contributing to global climate change. In addition, it helps reduce pollution created by burning fossil fuels for electricity generation and transportation purposes.

Small Scale Technology Certificates

Small-scale technology certificates are a great way to help the environment and save money on your energy bills. It’s also beneficial because you don’t have to worry about buying large amounts of expensive equipment that may not be compatible with your home or office. Investing in small-scale technology certificates will help protect our planet while also helping you save money on electricity costs.

Solar Rebates | STC's

Small-scale technology certificates, what are they how do you claim them are they being reduced, what are stc’s.

Most of our customers at Teho ask “are there any Government incentives for going solar?”. Our answer? Yes, yes there are, and they are known as STC’s. They aren’t technically a rebate however that is the name they have got over the years and when something looks like a rebate and smells like a rebate, maybe it’s a rebate?

An STC is a Small-Scale Technology Certificate. You will also hear them referred to colloquially as the Solar Rebate. Introduced in 2011 STC’s are a part of Australia’s Renewable Energy Target. This incentive or “rebate” serves the purpose of reducing the cost of installing solar on your home or business through the creation of these technology certificates. 

The amount of STC’s which are applicable to your solar system depends on the size of the system being installed. 

An average 6.6kW solar system in 2020 is entitled to 100 STC’s with the value of an STC being around $35. So, on a 6.6kw solar system you would get a total STC rebate of around $3,500.00 

How Do I Claim Them?

When purchasing solar you will notice on the quote the price is listed AFTER STC’s, this is because in most, if not all cases you will assign the STC’s over to your solar installer or retailer.

You might be wondering “why would I assign my rebate over to someone else!?” STC’s need to be claimed and this process is best handled by your installer or retailer. Once the system is installed, the installer or retailer will ask you to sign the STC’s over to them. Once this is done the installer or retailer will place this document with an aggregator for the rebate to be turned into real money. It takes the aggregator around 4 weeks to convert STC’s into cash . Plus, they can’t do it one job at a time – they need to combine 5,000 STC’s together to then be able to place them on the market at the current spot price. That is the equivalent of around 50 solar installations!

Once you have signed the STCs over to the retailer or installer you don’t have to do anything as you only have to pay the after STC amount. It’s all taken care of!

Are The STC’s Being Reduced?

Solar retailers and installers love to use the lowering STC amount as urgency to get customers to purchase immediately, no one likes missing out – and they know this! 

However, they sometimes use language which insinuates its ending very very soon, which just isn’t the case. 

The reality is that they are being phased out but not as quickly as anyone makes it out to be. 

The beginning of the phase out of the STC program officially started on the 1st of January 2017. 

Prior to 2017, you were given 15 years of STC’s in advance. As of January 1st 2017, it was reduced to 14. Every 1st of January for each year until 2030, it is reduced by one year until the program will end. So to put it more simply, the value of STC’s is reducing at around 7% a year compounding, until 2030 when it will be nil.  

So, they are being reduced but at no where near the rate lots of installers and retailers want you to believe. 

In saying that, the benefits of solar are vast so if you are in a position to install solar, the sooner the better does ring true to some degree.

Most frequently asked questions and answers

STC’s (Small-scale technology certificates) are a part of Australia’s  Renewable Energy Target. They are granted to new solar panel installations and generally signed over by the consumer to a 3rd party in exchange for a cash equivalent when getting solar installed.

STC’s value fluctuates as they are traded on a market. As of 2020 they have a cash equivalent value of around $38.

STC stands for Small-scale technology certificates.
