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.
Penrith's extreme summer heat drives high air conditioning costs, making batteries particularly valuable for peak demand management.
Penrith is served by Endeavour Energy. With 4.7 average daily sun hours, a well-sized battery system can significantly reduce grid dependence and electricity costs.
Penrith 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.
Hot summer afternoons drive electricity demand and prices sky-high. A battery charged from midday solar can power your aircon during expensive peak periods instead of paying premium rates.
