15kW Solar System Price and Overview

A 15kW solar system in Australia typically costs between $10,000 and $18,000 after applying government rebates and incentives. This cost includes professional installation and high-quality components, ensuring reliability and long-term efficiency. The actual price can vary based on your location, roof design, and energy needs, but the investment often pays for itself within 3 to 5 years through energy savings and feed-in tariffs.

A 15kW solar system is an excellent option for larger homes or small businesses, offering significant energy generation, reduced electricity bills, and a lower carbon footprint. With this system, you can take control of your power usage and contribute to a greener future.

Components of a 15kW Solar System

Solar Panels

A 15kW system typically requires 41 panels rated at 370 watts each, needing approximately 71.9 square meters of roof space. Panels convert sunlight into electricity for use in your property.

Inverter

Converts the DC electricity generated by the panels into AC electricity for your home or business. For a 15kW array, an inverter with an AC output of 11.25kW is often recommended. This ensures optimal performance and efficiency.

Inverters can be sized slightly less than the panel array, which improves overall efficiency. Fronius inverters are a popular choice for 15kW systems.

Battery Storage (Optional)

Stores excess energy generated during the day for use at night or during outages, reducing reliance on the grid.

Mounting System

Secures solar panels to your roof or ground setup.

Monitoring System

Tracks your energy production and consumption in real-time, helping you optimise system performance.

How Much Energy Will a 15kW Solar System Produce?

A 15kW solar system produces between 60 and 65 kWh per day on average, depending on factors like location, panel orientation, and shading. For example:

Canberra, ACT

  • Daily Output: 64.50 kWh
  • Annual Output: 23,543 kWh

This output is sufficient to power large households or small commercial properties while leaving surplus energy to export to the grid for financial credits.

Do You Need Battery Backup?

Adding battery storage to your 15kW solar system has several benefits:

Energy Independence

Batteries store excess energy for use at night or during power outages, reducing reliance on the grid.

Cost Savings

Stored energy can offset peak electricity rates, saving you more over time.

Emergency Power

Ensures an uninterrupted power supply during outages, which is especially important for businesses or homes with critical power needs.
