Battery storage for a solar PV system

Benefits of battery storage

Adding a battery to your solar system allows you to store excess electricity generated by solar panels for use when the sun isn’t shining. 

A battery storage system can:

  • Help reduce your reliance on electricity from the grid
  • Maximise your solar panels by allowing you to capture excess solar energy that would normally be sent to the grid and save it for your own usage later in the day
  • Offset the increased cost of power used during peak times
  • Save money by storing energy from the grid overnight when prices are low to use during peak times when prices are high (depending on your power agreement)
  • Provide electricity to your home during power outages (depending on your system)
  • Reduce your exposure to future electricity price rises
