In Perth, shifting to solar energy is a smart deal for the public because it not only helps save money on electricity bills but also makes the environment carbon-free.
The federal and WA state governments provide rebates and incentives that reduce the cost of a solar system, making it more affordable for people. When you install a battery with your solar system, you get two solar battery rebates: one from the federal government and one from WA state.
There are financing options available, such as Plenti and Green Loans, which offer interest-free or lower-interest options depending on eligibility criteria.
System Type | Solar System Average Price Before Rebate | Solar System Average Price After Rebate |
13.2 kW Solar System (No Battery) | $11,500 – $15,500 | $8,115 – $12,115 |
13.2 kW Solar + 20 kWh Battery | $22,500 – $32,500 | $16,834 - $26,834 |
Note: A 13.2 kW solar system typically includes high-efficiency solar panels and a 10 kW solar inverter, with prices generally ranging from $11,500–$15,500 after rebates. A 13.2 kW solar system paired with a 10 kW inverter and a 20 kWh solar battery typically costs around $22,500–$32,500 before rebates.
The total cost of your solar system depends on the brands you choose for the solar panels, inverter, and battery. Different manufacturers offer varying levels of efficiency, warranty, performance, and features, which can affect the overall price of the system.

Lower Electricity Bills: A 13.2 kW solar system generates around 50–60 kWh of electricity per day, helping reduce reliance on the grid. It is ideal for large households, home businesses, and properties with high energy usage.
Excellent Return on Investment: With the Federal STC rebate and WA battery rebate and ongoing electricity bill savings, a 13.3kW solar system typically offers a payback period of 3–5 years, depending on your energy consumption.
Future-Ready for EVs and Batteries: A 13.2 kW system provides ample capacity to support battery storage, electric vehicle (EV) charging, and smart home energy management systems.
Boosts Property Value: Homes with a 13.2 kW solar system are often more attractive to buyers, as they offer lower running costs, long-term energy savings, and improved energy efficiency.
Low Maintenance: Solar panels require minimal maintenance and can continue producing clean electricity for 25–30 years with proper care and regular inspections.

When your solar system generates more electricity than your home needs, the excess power is exported to the grid, and you may receive a feed-in tariff for that exported energy. The feed-in tariff amount depends on your electricity retailer, your location, and the amount of solar power you export.
Most of the time, Perth winter rain removes most dust from the solar panels. However, if you live near a construction site or an area with heavy bird activity, cleaning every 12 to 24 months can help maintain the performance of the solar system.
If you are going with a professional and licensed solar installer, he should not affect your roof warranty. Always use experienced, licensed installers who follow Australian Standards.
Yes. A 13.2 kW solar system is a good choice if you plan to buy an electric vehicle (EV). It generates enough daytime electricity to help charge your EV while also powering your home's appliances, reducing your reliance on grid electricity and lowering your energy costs.
