As electricity bills continue to rise across Australia, more homeowners and businesses are turning to solar energy to reduce their power costs and carbon footprint. Among the most popular solar options is the 10kW solar system, which offers substantial energy output and long-term savings. But one of the most frequently asked questions is: What’s the price of a 10kW solar system in Australia?

At Ads Solar, we specialize in delivering affordable 10kW solar systems without compromising on quality or efficiency. In this guide, we’ll break down the 10kW solar system price, explore what influences the cost, and help you decide whether it’s the right choice for your home or business.

What Is a 10kW Solar System?

A 10kW solar system refers to a system with solar panels that collectively produce 10 kilowatts of power under optimal conditions. It’s a substantial setup, ideal for:

Large households with high energy demands
Small to medium businesses
Homes with electric vehicles
Properties using electric heating/cooling systems

Depending on your location, sun exposure, and the efficiency of the components used, a 10kW solar system can generate 35 to 44 kWh per day.

10kW Solar System Price in Australia (2024)

The average price of a 10kW solar system in Australia ranges from $7,000 to $14,000, depending on various factors. At Ads Solar, we offer custom 10kW solar solutions starting from just $8,999, inclusive of Tier 1 panels, a quality inverter, and professional installation.

Here’s a typical price range breakdown:

System Type — Estimated Cost (After STC Rebate)

Standard System (Good value & warranty): $8,500 — $11,000

Note: Pricing varies based on brand, installation complexity, and location. Ads Solar guarantees affordable 10kW solar system prices across Sydney, Melbourne, Brisbane, and Adelaide.

What’s Included in a 10kW Solar System Package?

When you invest in a 10kW solar system with Ads Solar, your package typically includes:

25–27 high-efficiency solar panels (370W–400W each)
1 high-quality inverter (10kW single-phase or 3-phase)
Professional installation by Clean Energy Council (CEC) accredited installers
Wi-Fi monitoring system
Performance and product warranties (up to 25 years)
Post-installation support & maintenance options

We also offer battery-ready 10kW solar systems, which allow you to add solar batteries later if you want to achieve energy independence.

Factors Affecting the Cost of a 10kW Solar System

Several variables can affect the total cost of your 10kW solar installation:

1. Panel & Inverter Brands

Higher-end brands like SunPower, REC, or LG for panels and Fronius, Sungrow, or SolarEdge for inverters will cost more but often offer better performance and longer warranties.

2. Roof Type & Installation Complexity

Flat, multi-story, or shaded roofs require more labour, materials, and sometimes custom mounts, which can increase costs.

3. Location

Pricing may vary slightly depending on your city due to transportation, labour rates, and solar rebate zones. Ads Solar serves all major cities including Sydney, Melbourne, Brisbane, and Adelaide, offering competitive regional pricing.

4. Government Rebates & Incentives

The Small-scale Technology Certificate (STC) rebate significantly reduces upfront costs. A 10kW system can receive rebates worth $3,000 to $5,000, depending on location and STC value at the time of installation.

5. Battery Storage (Optional)

Adding a battery like a Tesla Powerwall or Sungrow Battery can add $8,000 to $12,000 to your system cost. However, batteries allow you to store excess solar energy for night-time use or backup during blackouts.

How Much Can You Save with a 10kW Solar System?

The savings from a 10kW solar system can be impressive:

Daily energy output: ~35–44 kWh/day
Monthly savings: $350–$550 (depending on your energy consumption and feed-in tariff)
Annual savings: Up to $6,000
Payback period: Around 3–5 years (on average)

Once the system is paid off, you enjoy decades of virtually free power.

Is a 10kW Solar System Right for You?

A 10kW solar system is ideal for:

Homes using 30–40 kWh/day or more
Households with pools, electric cars, or reverse-cycle air conditioning
Businesses operating during the day
Families planning future battery storage

If you have ample roof space (40–50m² of unshaded area) and high energy usage, this system will future-proof your energy needs and deliver great returns.

10kW Solar System with Battery Storage

More homeowners are choosing to pair their 10kW systems with batteries. Although it increases the upfront cost, it enhances energy independence, especially with rising electricity rates.

Popular solar battery options include:

Tesla Powerwall 2 (13.5 kWh)
Sungrow Battery
AlphaESS
LG Chem

With a battery, you can:

Store excess solar energy for night-time use
Avoid drawing from the grid
Protect your home during power outages
Maximise ROI and energy independence

Ads Solar offers custom solar + battery packages to suit your lifestyle and budget.
