As more homeowners and businesses make the switch to renewable energy, one question continues to pop up: “How much does it cost to install solar in Melbourne?” Whether you’re a first-time buyer or just curious about the savings and pricing, understanding the cost breakdown is essential. At Australian Design Solar, we’re here to provide clarity and value-packed solutions tailored to Melbourne’s unique energy needs.

Why More Melburnians
Are Going Solar

Before we dive into numbers, let’s quickly touch on why solar installation in Melbourne is booming. Energy prices are on the rise, and people are looking for ways to reduce their electricity bills and lower their carbon footprint. Plus, government rebates and incentives are making solar more affordable than ever.

With Melbourne’s mix of sunny days and supportive solar policies, investing in a solar power system is both financially and environmentally smart.

So, What’s the Average Cost of Installing Solar in Melbourne?

System Size	Average Cost (After STC rebate)	Ideal for
3kW	$2,500 – $4,800	Small homes / low energy usage
5kW	$3,800 – $6,500	Medium homes / families
6.6kW	$4,500 – $7,200	Average family homes
10kW	$7,000 – $12,000	Large homes or small businesses
13.2kW	$10,000 – $15,000	High energy users / commercial setups

Note: Prices can vary depending on the brand of panels and inverters, the complexity of the installation, and the location of your property.

Key Factors That Affect Solar Installation Costs in Melbourne

No two installations are the same. Several variables impact the final cost of a solar energy system in Melbourne, including:

1. System Size

This is the biggest factor. A larger system naturally costs more upfront but provides more energy, bigger savings, and a faster return on investment.

2. Solar Panel Brands and Quality

You’ll find various panel brands like SunPower, Q Cells, Longi, and Jinko. Premium panels offer better efficiency and longer warranties but come at a higher cost.

3. Inverter Type

The inverter is the brain of your solar system. You can choose from:

• String Inverters (most common and cost-effective)
• Microinverters (ideal for shaded roofs, slightly pricier)
• Hybrid Inverters (allow for battery integration)

4. Installation Complexity

Do you have a multi-story house? A flat or tiled roof? Obstacles like skylights or trees? These can increase installation time and labor costs.

5. Rebates and Incentives

The Small-scale Technology Certificates (STCs) rebate significantly reduces the upfront cost. In Victoria, homeowners may also be eligible for Solar Victoria Rebates of up to $1,400 plus an interest-free loan.

6. Battery Storage

If you want energy independence or backup during blackouts, adding a battery like the Tesla Powerwall will increase your cost by $8,000 to $13,000 – but can also boost your savings and reliability.

How Much Can You Save With Solar in Melbourne?

It’s not just about how much you spend—it’s about how much you save. On average, Melburnians can cut their power bills by 50–80% with a properly sized solar system. For example:

• A 6.6kW system can save you up to $1,200 – $1,800 annually.
• A 10kW system can slash bills by $2,000 – $3,000 a year.

Most systems pay for themselves in 3 to 5 years, and with a lifespan of 25+ years, that’s decades of free power!
