Mount Barker Feed-in Tariffs

The current feed-in tariff in SA is approximately 4.0c/kWh for excess solar exported to the grid. With feed-in rates this low, maximising self-consumption (using solar during the day) is more valuable than exporting. A battery can help shift solar to evening use.

At current rates, a 6.6kW system in Mount Barker exporting around 60–70% of generation would earn approximately $301/year in feed-in credits. The real savings come from self-consumption — every kWh you use directly saves 38c versus the 4.0c you'd earn exporting it.
