SA Home Battery Scheme – What to know

by

The Home Battery Scheme is a subsidy for all grid-connected systems – provided by the Clean Energy Finance Corporation – to help pay for the cost of a home battery system.

It is available to all South Australians buying a energy-storage equipped solar PV system.

The subsidy only covers the battery component of a system.

The subsidy is calculated on the kilowatt hour capacity of battery purchased. Energy Concession Holders are eligible for a higher subsidy, to support low-income households to access this scheme.

The scheme does not apply for off-grid systems and subsidies for batteries are eligible for grid-connected systems.

Note that the subsidy decreases as more people apply for the scheme, we are now in step 3 where subsidies went from $6000 to $2000 as of date, the phase will see subsidies drop to $1000.

What is a home battery system?

A home battery system is your typical grid connected system, along with a battery. If you already have solar panels on your roof, ensure your inverter allows for hybrid-capable before installing a battery.

Batteries allow you to store excess generation from your solar panels ready for use whenever your solar panels are unable to produce solar power – such as cloudy periods or when the sun goes down. By storing and therefore using more of the energy generated by your solar system, you effectively use less energy from the power grid and it saves you money on your power bill.

This results in lower electricity costs overall for households who purchased a home battery system. The more households that own a home battery system, demand on the power network will reduce and will lower electricity prices for all South-Australians.

Is a battery/solar right for me?

To be honest, battery storage alone can be more expensive than a standard solar PV system. It is not for everyone and there a few things to consider before making the investment into a battery for your home. Here’s some general guidelines to consider:

  • Your electricity usage. How much energy you use each day, when you use energy the most, 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, how much excess solar energy you have available to store in your battery.
  • If you value having power in a blackout, finding out which battery systems provide blackout power and what they can typically power during a blackout.
  • How adding a battery may affect any feed-in tariff you currently receive.

How much can I save?

How much you would save on your power bill would depend on the output of your solar panels and the capacity of the battery, as well as how much energy you use and what time of day you use energy the most.

Most importantly, you should consider the payback period of a home battery system, and justify whether the energy savings would be worth it.

Can I afford it?

The cost of a home battery system would depend on the capacity of the battery and whether you need 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 Plenti – the administrator of the Home Battery Scheme subsidy and finance provided by the Clean Energy Finance Corporation.

Can I access the scheme more than once?

Yes. If you own multiple properties, you can access the subsidy more than once. However, the property must be a residential property and you can only access the subsidy once per property.

You will be required to provide the National Metering Identifier (NMI) of the property when applying for the subsidy (this can be found on your bill).

I already have a solar system; would this affect my feed-in tariff?

Yes unfortunately it would, this applies if you were to add more panels to an existing system or install a battery. This would differ from retailer to retailer, speak with them to see the new feed-in tariff rates you would receive.

How much additional space would I need and where would it be stored?

Typically, a home battery system is between 30 – 125 kilograms, and between the size of a microwave and the ‘outdoor’ part of a split cycle air conditioning unit, depending on the energy storage capacity. Batteries can only be installed outdoors or inside a garage and they are often mounted to the wall, but can also be installed on the floor.

Will the battery work in a blackout?

Not all home-battery systems offer ‘blackout protection’, you would need to request this feature as it may mean getting additional components.
