15 April 2021 New rooftop solar installations in parts of South Australia will face the choice of agreeing to “flexible” solar export arrangements, or be limited to a hard 1.5kW limit under new rules to be introduced within months by the local distributed grid owner, SA Power Networks The new options are expected to impact households installing rooftop solar systems for the first time, or upgrading their existing installations, in certain “congested” parts of the grid, most likely in parts of Adelaide’s southern suburbs. It will mean that they can choose between a “flexible” export option, which will allow up to 10kW of export capacity in return for the ability of SAPN to lower those export limits “periodically” to manage the local grid, or be restricted to a hard limit of just 1.5kW.
