Solar Battery Storage Price Australia (2026 Guide): How Much Does It Cost to Install a Solar Battery? — Australian Design Solar

If you’ve been thinking about adding a solar battery to your home, you’re not alone — solar battery storage is one of the fastest-growing energy technologies in Australia. With electricity prices rising and feed-in tariffs dropping, more homeowners are actively looking for ways to store excess solar power and reduce their dependence on the grid.
But the number-one question is always the same:

“How much does a solar battery cost in Australia?”

In this 2025 expert pricing guide, we’ll break down the solar battery storage price in Australia, including costs per kWh, installation pricing, top brands, rebate savings, and real-world examples — all written by an expert solar energy writer for Australian Design Solar.

Let’s dive in.

Why Solar Battery Storage Is Booming in Australia

Solar battery demand in Australia has doubled in the last five years — and for good reason. With more than 3 million homes now using solar, adding a battery is the logical next step.

A solar battery allows you to store excess solar energy during the day and use it at night instead of buying costly grid electricity. This gives you:

• Lower electricity bills
• Backup power during blackouts
• Reduced reliance on the grid
• Better return on solar investment
• Increased property value

For many Aussie families, a solar battery is no longer a luxury — it’s a smart financial and lifestyle upgrade.

Solar Battery Storage Price Australia (2026 Updated Pricing)

Here’s the latest 2025 pricing guide for solar batteries in Australia, including supply + installation:

Solar Battery Size (kWh)	Average Installed Price (AUD)	Suitable For
3–5 kWh	$3,000 – $6,000	Small units / light users
7–10 kWh	$7,000 – $10,000	Small to medium households
13.5 kWh (Tesla size)	$12,000 – $15,000	Medium to large homes
15–20 kWh	$15,000 – $20,000	High-energy homes / small businesses

✔ Most Australian households choose 10–13.5 kWh, as it offers the best balance between price, performance, and night-time usage.

✔ Prices are influenced by brand, chemistry, installation type, and your existing solar system.

Solar Battery Price Per kWh Australia (2026)

To understand value, you must consider the cost per kWh of usable battery capacity.

In Australia, the average solar battery price per kWh is $900 to $1,400 per kWh installed.

• Budget batteries → $800–$1,000 per kWh
• Mid-range (Sungrow, Alpha ESS) → $1,000–$1,200 per kWh
• Premium batteries (Tesla, Enphase) → $1,200–$1,400 per kWh

This metric helps calculate value and compare brands effectively.

Solar Battery Installation Cost Australia

On average, solar battery installation costs between $1,000 and $2,000, depending on:

• Your existing switchboard
• Whether you need a hybrid inverter
• Location of battery
• AC-coupled vs DC-coupled installation
• Backup/essential load wiring

At Australian Design Solar, you get transparent, upfront installation pricing — no surprises, no hidden fees.

Factors That Influence Solar Battery Storage Price

The cost of a solar battery system varies depending on:

1️⃣ Battery Capacity (kWh)

Bigger batteries cost more, but reduce grid reliance more effectively.

2️⃣ Battery Brand & Technology

Premium brands like Tesla cost more due to smart monitoring, backup features, and advanced chemistry.

3️⃣ Battery Chemistry

LFP (Lithium Iron Phosphate) is safer, lasts longer, and is becoming industry standard.

4️⃣ Hybrid vs Retrofit Setup

If you already have solar panels, adding a battery may require:

• New hybrid inverter
• Additional electrical upgrades

5️⃣ Backup Power Options

Full-home backup increases price. Essential load backup is cheaper.

6️⃣ Labour & Site Conditions

Location of installation, cabling, and accessibility all play a role.

✔ Federal STCs: Reduce solar system costs (battery-ready systems qualify).

✔ Feed-in Tariffs: Earn money for excess energy exported to the grid.

✔ State Programs: Some states offer extra solar battery incentives (NSW, VIC, SA at times depending on the year).

✔ Interest-Free Loans: Available in certain states for renewable upgrades.

Australian Design Solar assists customers with all eligible rebates to maximise savings.

How Much Can a Solar Battery Save You?

A properly sized solar battery can reduce energy bills by 60–80%.

Average Annual Savings: Households typically save between $1,200 and $2,000 per year, depending on system size and electricity usage patterns.

Most Australian homeowners achieve a return on investment within 5–8 years, influenced by consumption habits, tariff structure, and battery capacity.

With proper installation, modern solar batteries can operate efficiently for 10–15 years, providing consistent performance and long-term financial benefits.

For example, a Sydney family that installs a 10kWh battery may significantly reduce evening grid reliance and cut peak electricity costs.

Before installation, their electricity bill averaged $420 per month. After adding a battery system, monthly costs dropped to approximately $110–$150. This reduction translates to estimated annual savings of around $2,500.

This is why solar batteries are booming across Australia.
