Double your solar exports!

Considering solar for your home? You could be eligible to take advantage of the new Flexible Exports option from SA Power Networks.

Flexible Exports will allow customers to export the maximum amount that the network and their inverter can handle – 10kW per phase most of the time.


Find out more about Flexible Exports


Partnering with the solar industry, we have developed the “Flexible Exports” option enabling new or upgrading solar customers to export up to 10kW per phase from their solar panels, double the current standard export limit. 

As part of a world-first trial, we are first offering Flexible Exports to households looking to connect or upgrade solar in areas supplied from our Sheidow Park substation, which includes parts of Hallett Cove, Sheidow Park, Trott Park, Reynella, Old Reynella, Reynella East, O'Halloran Hill and Happy Valley.  

Using selected smart solar inverter systems, Flexible Exports will enable solar exports that vary between 1.5kW up to 10kW throughout the day, depending on the capacity of the local network in your area. 

With Flexible Exports, solar exports are automatically adjusted to maximise the amount of solar that can be connected and exported to the electricity grid. We estimate this will allow you the opportunity to export up to 10kW 98% of the time, depending on the size of your system, the amount of solar in your area and reliability of your internet connection.  

There is also a 1.5kW fixed export connection option available for customers who do not wish to take up Flexible Exports. 

Enabling more solar for South Australians   

Did you know South Australia is leading the world when it comes to solar? South Australians have installed more rooftop solar per capita than anywhere else in the world – one in three South Australian homes are connected to solar. 100% of the State has been powered by solar energy, and with more than 60% of the state’s energy needs are met by renewables in 2020.  

We’re actively working towards our goal of doubling the amount of solar connected to our network by 2025 by developing innovative solutions to help connect more solar and enable new technologies. 

Introducing Flexible Exports will help us: 

  • Allow more people to install and benefit from solar 
  • Enable greater solar exports into the network 
  • Maintain a safe, reliable and affordable electricity supply 
  • Support achievement of South Australia’s renewable energy goals

For most of the time Flexible Exports will allow customers to export the maximum amount that the network and their inverter can handle – between 1.5kW up to 10kW per phase. Smart, internet-connected solar systems will receive flexible export limit updates via the internet, based on network capacity at their location. The system will then adjust exports accordingly.

During limited periods, export limits will be lowered to avoid overloading the network.

The Flexible Exports option is for new solar connections and upgrades within overloaded parts of the network and will be offered initially in areas served by the Sheidow Park substation, including parts of Hallett Cove, Sheidow Park, Trott Park, Reynella, Old Reynella, Reynella East, O’Halloran Hill and Happy Valley from 23 September 2021, and more into the future.

New and upgrading solar customers who are connecting to these significantly overloaded parts of the network will be offered a choice of either a fixed export limit (1.5kW per phase) or the Flexible Export option (1.5kW to 10kW per phase).

Analysis shows the flexible export limits will typically be 10kW for 98% of the time. Outcomes will vary with the location of the customer and the reliability of their internet connection.

There are three key benefits of Flexible Exports, which will help to:

  • maximise the number of customers able to install and benefit from solar
  • maintain a safe, reliable and affordable electricity supply
  • support achievement of South Australia's renewable energy goals.

A flexible limit that varies from 1.5kW-10kW per phase will, by definition, provide more benefits than a low, all-year around fixed limit of 1.5kW per phase. 

Analysis shows the flexible export limits typically be 10kW for 98% of the time. Outcomes will vary with the location of the customer and the reliability of your internet connection. 

Your solar installer will help you work out the most cost-efficient solution from the range of options and equipment available. 

Flexible Exports will be offered via solar installers to any customers located in particular overloaded areas of the network who are purchasing residential rooftop solar for the first time or upgrading their solar equipment. This overloaded areas of the network initially includes areas served by the Sheidow Park substation, including  parts of Hallett Cove, Sheidow Park, Trott Park, Reynella, Old Reynella, Reynella East, O’Halloran Hill and Happy Valley, and more into the future.

Customers will be able to opt in for Flexible Exports as an alternative to reduced fixed export limits, provided they select equipment that is listed as compatible with the Flexible Exports option. Your solar installer will let you know if you are being offered this new connection option based on your location. We anticipate this will affect less than 2% of solar applications in the first year.

Following the trial, we plan to offer Flexible Exports to all new and upgrading solar customers as a standard service offering. In the unlikely event Flexible Exports not proceeding, customers already on this option will be revert to the fixed export limit of 5kW per phase.

At this stage, Flexible Exports will only be offered to customers in selected overloaded areas looking to connect new solar to the network, or those who are making significant upgrades or changes to their solar systems. For existing solar customers, your current arrangements will not change unless or until you want to upgrade your system and you’re in an overloaded area of the network.
