Solar Battery Cost

Home batteries are the way to go if you want to get the most out of your solar power system system, as you can power your home from solar energy 24/7.

From a financial perspective, solar batteries make much more sense than they did previously, as they’re far cheaper than they were before, c/o the Federal Cheaper Home Batteries Program (CHBP) and the NSW VPP rebate , which together bring down the cost of battery storage systems by around 35%. The business case for batteries storage now really stacks up.

Here are some examples of how much solar batteries cost. These figures are after the Federal government rebate has been deducted, but the VPP rebate of up to $1,500 has not been factored in, as homeowners need to apply for this themselves:
Battery type System Cost
9.6kWh battery Sungrow 5kW inverter / Sungrow 9.6kWh battery From $9,390
Every additional 3.2kWh battery: from $485 – $1000*
10kWh battery SolarEdge 10kWh Home Battery $9,950
Add a supplementary 10kWh battery: from $6,115
14kWh battery Tesla Powerwall 3 14kWh From $13,190
Add a supplementary 14kWh battery: from $8,660
16kWh battery SigEnergy 10kW inverter / SigEnergy 16Wh battery From $12,850
Every additional 8kWh battery: $3500 – $4,330*
16.6kWh battery Goodwe 10kW inverter/Goodwe 16.6kWh battery From $9,490
Every additional 8.3kWh battery: $2600 – $2840*
20kWh battery Sungrow 3 phase hybrid inverter / Sungrow 20Wh battery From $18,490
Add a supplementary 5kWh battery: $2,600
24kWh battery SigEnergy 10kW inverter / SigEnergy 24Wh battery From $16,350
Every additional 8kWh battery: $4,330*

The above pricing includes supply and installation. Assumes supplementary batteries will be installed at the same time as the initial battery storage system and not retrofitted at a later date.

* Cost of additional battery modules depends on rebate threshold (you’ll receive 100% of the rebate value for batteries up to 14kWh, then the value drops to 60% for 15-28kWh of storage capacity, and it drops to 15% of the rebate value for 29-50kWh of storage capacity).

Note: to meet Australian Standards, there are only certain locations on your property where a battery can be positioned. We typically organise a pre-installation site visit to determine best battery location.

To achieve the fastest ROI on solar and storage, look at joining a Virtual Power Plant (VPP), which can hasten the payback of a battery storage investment by up to 20%.

To help with the cashflow, you might also consider taking advantage of a low-interest Green Loan , which makes it affordable to install home batteries, as you don’t need to put your hand in your pocket to pay for your system. Under this arrangement, the reduction in your bill by having solar & batteries installed and you using your free power day & night, can outweigh the bulk of your loan repayments. We work hand-in-hand with a local lending broker to ensure you can get access to the best finance solution for your battery storage system. As more banks and lenders now offer ultra-low rate finance for upgrades like solar and batteries, our broker finds you the lowest rate available, without impacting your credit score.

Solar battery storage savings

You can reduce your reliance on the grid by as much as 100% with a solar and battery system. To provide you with an accurate solution, we highly recommend a Free Home Assessment.

Solar battery alternatives

Larger solar battery storage systems can be pricey, so it’s good to know there are more affordable alternatives to batteries that can help you achieve a similar financial result, such as:

  • Solar energy diverters – allow you to divert any surplus solar energy to pre-heat your electric hot water system before exporting the remaining excess to the grid. Meaning your hot water system doesn’t need to run for as long overnight as the water has already been pre-heated by electricity generated from your solar panels. It effectively turns your electric hot water system into a solar hot water system.
  • Smart relays – these can be connected to many electrical appliances. When there’s surplus solar energy, these clever units can switch on equipment like air-conditioning, pool pumps and heat pumps. Should a cloud block the sun and your solar production suddenly decreases, the smart relay will stop sending surplus solar energy to the appliance until the sun reappears.

A decent size solar battery (10kWh-16kWh) typically costs between $10,500 and $18,000, while these types of units cost around $1,300 – $1,400 supplied and installed.
