How much does a solar battery cost and what size is best for your home?

The size and cost of a solar battery system depend on many factors, such as the size of the home and the amount of electricity that is consumed. 

When assessing your home, your installer will access your household requirements, helping guide you to a recommended system. To help you prepare, we’ve shared some of the common questions an installer will ask you on the day:

  • Electricity use: The solar battery system should be sized to provide enough storage capacity to meet the household's electricity needs. This will depend on the amount of electricity that is used on a daily basis, as well as any seasonal variations in usage. To determine the optimal size, your battery installer will ask for your three latest energy bills.
  • Solar panel system size: The solar battery system is required to match the solar power system, this will ensure that the solar battery system can store any excess electricity that is generated by the panels, so it can be used when needed.

Brighte Tip: Before adding a solar battery to your system, talk to your installer about any future household consumption plans as it might identify the need for more solar panels at a later stage. For instance, if you are looking to install a spa, or you are looking to purchase an electric vehicle, you might consider investing in some additional panels and a larger battery. 

What is the cost of a solar battery system?

Different types of solar battery systems have different storage limits and prices. Your chosen solar battery installer will provide options and guidance based on your household requirements and budget, the price may vary between $7k to $15k.
