What is A Solar Feed-In Tariff?
A Solar Feed-in Tariff (FiT) is a payment made to eligible solar PV systems for the excess energy they generate and send back to the electricity grid. When your system produces more electricity than your household uses, the surplus energy is exported to the grid. In return, you receive a payment per kilowatt-hour (kWh) from your electricity retailer, which is credited to your energy bill.
How Do I Qualify for a Solar Feed-in Tariff?
To qualify for a feed-in tariff, you must have an eligible solar PV system that is connected to the electricity grid. An eligible system involves meeting state or territory-mandated standards and requirements.
The installation of your system must be carried out by a licensed and accredited installer. Accredited installers ensure that the system is installed correctly and safely based on the latest standards and regulations.
Some electricity retailers will set minimum or maximum system size limits for eligibility. For example, a system might need to be under 10 kW to qualify for certain feed-in tariffs. We’ll cover more on system size limits down below.
You must also have an approved metering system to measure the energy you export to the grid accurately. This often involves installing a smart meter, which records your energy consumption and export.

7What Are the Solar System Size Limits in SA?
In Australia, there are guidelines that regulate the maximum size of a solar system. These guidelines vary depending on your network, where your home is located, and whether your home is a single-phase or three-phase connected property.
But first, let’s break down the main differences between a single-phase and a three-phase connected property. What separates these two connections is the power supply capacity and usage. A single-phase connection is generally used in residential settings, providing adequate power for household appliances. It consists of one active wire and one neutral wire, delivering power in a single alternating current (AC) wave. In contrast, a three-phase connection, commonly used in commercial and industrial settings, delivers electricity through three active wires and one neutral wire, which makes for a more consistent energy supply. This type of connection is ideal for powering large equipment and machinery with high energy demands, like commercial properties or large-scale residential properties.
Each state or territory has separate regulations and guidelines set by the local distribution network operators. Here’s an overview of solar system size limits in SA:
Network | System Size Limits |
|---|---|
|
SA Power Networks |
Single Phase: Up to 5kW Three Phase: Up to 30kW (Battery inverter capacity is counted towards the total allowable capacity.) |
Minimum Feed-In Tariff in SA
The minimum solar feed-in tariff refers to the rate paid by electricity providers for the excess solar energy your system exports to the main grid. This rate can vary depending on the retailer and the specific plan you choose.
As of 2024, South Australia’s regulatory body does not set a mandatory minimum feed-in tariff. Electricity retailers voluntarily set their rates, so consumers need to shop around for the best deal.
9Can I Upgrade My Solar PV System?
Yes, you can. Upgrading your solar PV system can be a great way to enhance your energy efficiency and lower energy costs.
First, you’ll need to assess whether your current solar energy system meets your energy needs. If you’re using more electricity than your system generates or want to increase your savings, an upgrade might be necessary. This could involve installing more solar panels, upgrading to a larger inverter, or integrating battery storage to store excess solar energy for later use.
If your current solar inverter is not being used to its full capacity, you may be able to add more solar panels up to the inverter’s limit. Before you do this, make sure that the new panels are compatible with the existing ones to reduce the risk of performance issues. Also, consider whether you have sufficient space on your roof for additional panels.
Adding battery storage to your solar power system allows you to store surplus energy generated during the day for use during peak demand or at night. This can help reduce your reliance on the grid and potentially save you more money. Some common battery integration options include a hybrid inverter or adding a dedicated battery inverter alongside a new standard inverter.
Frequently Asked Questions
- What Are the Financial Benefits of a High Solar FiT?
High feed-in tariffs can expedite the payback period of your solar power investment. The more you earn from exporting electricity, the quicker you can recoup the initial costs of your solar panels and installation. This faster return on investment (ROI) makes the upfront cost of solar PV systems more justifiable and appealing to residential consumers and businesses.
Another benefit is the increased earnings you can receive for the extra energy your system generates and exports to the grid. A higher rate per kilowatt-hour (kWh) can mean more money back into your pocket. For example, a larger system producing 1000 kWh of energy per month with a 15 cents per kWh feed-in tariff would generate $150 monthly or $1,800 annually. Comparatively, a 6 cents per kWh feed-in tariff would result in $60 per month or $720 annually, meaning a $1,080 difference annually.
It’s important to note that the highest feed-in tariff will not always save you more money in the long run. Some energy retailers might offer high feed-in tariffs but balance this by increasing the usage rates for the electricity you consume from the grid. This means that while you earn more from exported energy, your savings could be offset by higher costs for the energy you purchase from the grid. - Are There Government Incentives For Solar Installations in South Australia?
Government incentives, such as rebates and subsidies, can reduce the upfront cost of installing a solar PV system. Combining these incentives with a favourable feed-in tariff can maximise your financial benefits.
