Technical FAQs 4

Why is home solar battery storage so popular in Australia?

Home solar battery storage is becoming increasingly popular in Australia to reduce reliance on the grid, save money on electricity bills, and protect against power outages. As of early 2025, approximately 185,800 home battery systems have been installed across Australia, marking a significant surge in adoption.

How many kWh is a solar battery in Australia?

In Australia, the average battery capacity is between 10kWh and 14kWh. This is enough to store the energy generated by a 6.6kW to 10kW solar system on a sunny day. However, if you have a larger household or want to store energy for several days, you may need a larger battery.

How much solar energy does Australia generate a year?

Indeed, the positive figure of these recorded generation statistics is that cumulative solar generation has increased by 15% year-on-year, with May 2024 seeing Australia’s fleet generate 2,486GWh in the NEM. Below is a full breakdown of monthly solar generation in the NEM on the graph, exclusive to PV Tech Premium subscribers.

How many MWh of energy storage is deployed in Australia?

According to figures published this week by solar PV and energy storage market consultancy Sunwiz, 2,468MWh of energy storage was deployed in Australia, with numbers in every segment surpassing the highest annual figures on record.
