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.
Melbourne households face some of Australia's highest peak electricity rates, making batteries particularly valuable for shifting solar energy to expensive evening hours.
Melbourne is served by Multiple (CitiPower, Powercor, United Energy, Jemena, AusNet). With 4.3 average daily sun hours, a well-sized battery system can significantly reduce grid dependence and electricity costs.
Melbourne residents qualify for the Cheaper Home Batteries Program:
Victoria's Solar Homes battery rebate and interest-free loans are no longer available. Victorians can access the federal rebate.
Melbourne's variable weather and high peak tariffs make 10-15kWh batteries ideal. Popular choices include Tesla Powerwall 3 (13.5kWh) and BYD Battery-Box (various sizes). The key is covering evening usage from 5-10pm when rates are highest.
Melbourne households with solar can save $800-1,500 per year with a correctly sized battery. Savings come from avoiding peak rates (often 35-45c/kWh) by using stored solar instead of grid power during expensive evening hours.
Yes! Melbourne averages 4.3 sun hours daily. While less than northern states, Melbourne's high electricity prices and time-of-use tariffs mean batteries can still achieve 6-8 year payback periods.
