As more Australian households and businesses transition to renewable energy, solar batteries have become a powerful tool in maximising energy independence. Among them, the 10kW solar battery stands out as an ideal solution for medium to large homes and small businesses. But how much does a 10kW solar battery cost in Australia in 2026?

Let’s explore the 10kW solar battery price, factors affecting cost, popular brands, government rebates, and whether it’s a worthwhile investment for your energy needs.

What is a 10kW Solar Battery?

A 10kW (kilowatt) solar battery typically refers to a system capable of storing around 10 kilowatt-hours (kWh) of energy or more, allowing homeowners to store excess solar power generated during the day for use at night or during power outages.

This size battery is suitable for:

  • Homes with 5-6 residents

  • Average daily electricity consumption of 25–35 kWh

  • Households aiming for greater energy self-sufficiency

  • Businesses with moderate energy needs

How Much Does a 10kW Solar Battery Cost in Australia in 2026?

In 2026, the installed price of a 10kWh solar battery in Australia ranges from $10,500 to $13,800, including GST and standard installation.

If You Don’t Already Have Solar Panels

A quality 10kW solar panel system costs $8,000 – $12,500 after STCs.

So a 10kW solar + 10kWh battery package typically lands at:

$19,000 – $26,000 (before battery rebates)

What Affects the Price of a 10kWh Solar Battery?

A 10kW solar battery quote may look simple, but several factors influence the final cost.

1. Battery Chemistry & Safety Standards

Most modern batteries use Lithium Iron Phosphate (LFP) for:

  • high safety

  • long lifespan (6,000+ cycles)

  • stable thermal performance

Higher-quality cell architecture increases cost but improves reliability.
