Is a battery/solar right for me?

Battery storage is an exciting new technology, but there are a few things to consider before making an investment in a battery for your home.
As a guide, you’ll need to consider:

  • Your electricity usage. How large your house is and what appliances you want to run from your battery.
  • The cost of the battery system (including installation and maintenance costs) you are looking to purchase, and how long will it take to recoup those costs from your expected energy savings.
  • If you already have a solar system, you'll need to find out what battery systems work best with your existing solar system as this may affect the price.
  • You may also wish to speak to your retailer about how adding a battery may affect any feed-in tariff you currently receive.

Different systems suit different needs so it’s important to talk to a qualified System Provider when doing your research.

How much will I save?

How much you could save on your energy bills depends on a number of factors including the output of your solar system and capacity of the battery, as well as the amount of energy your household uses and what time of day you use energy the most.

It is important for all households to consider whether the expected energy savings over the life of the battery will cover the cost of purchase.

Households should seek advice from a number of qualified System Providers when obtaining quotes for a home battery system.

Can I afford it?

The cost of a home battery system varies depending on the size of the battery, and whether you need to purchase new or additional solar panels. As a guide, download the HBS System Price Guide.

Subject to credit approval, low interest loans are available to assist participating households pay for the balance of the battery and new solar panels if required. When applying for the subsidy, a loan application can be made through RateSetter - the administrator of the Home Battery Scheme subsidy and $100 million in finance provided by the Clean Energy Finance Corporation.

Use the RateSetter Home Battery Scheme calculator to calculate your loan repayments.

“I’m 65 this year, so by the time I’m close to 70, I want my bills to be covered. Seeing the first bill in black and white was important to me. When I saw there was a two cent credit, I thought ‘I’m not going to spend any money this quarter’.” ~ Ray
