89% of battery charging from solar
In winter months, grid charging tops up your battery. With the right energy plan, you can charge during off-peak periods at very low rates - or even free.
Monthly averages based on typical weather. Cloudy days and seasonal variation mean some days will need grid top-up to fully charge your battery. Assumes ~35% of daily usage (5 kWh) during solar hours.
The Central Coast has one of NSW's highest rates of rooftop solar installation, creating strong demand for battery storage.
Central Coast is served by Ausgrid. With 4.6 average daily sun hours, a well-sized battery system can significantly reduce grid dependence and electricity costs.
Central Coast residents qualify for the Cheaper Home Batteries Program:
NSW offers a VPP incentive worth $40-55 per kWh of battery capacity, which nearly doubled from 1 July 2025 and stacks with the federal rebate.
High existing solar penetration means many homes are already exporting valuable solar energy for low feed-in rates. A battery captures this value instead.
