13kW Solar System Price

The average cost for a 13kW solar system in Australia ranges between $10,000 and $18,000. This cost includes the government rebate and GST, making it affordable for both residential and commercial properties. However, the final price can vary depending on factors such as location, the quality of materials, the type of inverter used, and the solar provider you choose.

This system generates 40-60 kWh per day, making it ideal for large households, small businesses, or properties that need a lot of power.

As a general guide, you can expect to pay approximately $1,000 per kW. While some providers may quote lower prices, it’s essential to consider the quality of materials, workmanship, and warranties offered to ensure a reliable and efficient system.

Components of a 13kW Solar System

A 13kW solar system typically includes the following components:

Solar Panels

Capture sunlight and convert it into electricity. A system this size requires approximately 33 panels, each producing around 400 watts, and will need about 56.1m² of roof space.

Inverter

Converts DC electricity from the panels into AC electricity for use in your home or business. While your solar array might produce 13kW, an inverter with an AC output of 9.75kW is often recommended for optimal efficiency.
Inverters can be sized slightly less than the panel array, which improves overall performance and avoids unnecessary inefficiencies. For example, a 13kW system may include a residential Fronius inverter.

Note: Inverters have varying specifications, and some may allow more panels than the rated inverter capacity.

Battery Storage

  1. Stores surplus energy for use during peak hours or power outages.

Mounting Structure

A mounting device helps secure the panels to your roof or ground setup.

Monitoring System

Tracks energy production and usage in real time.

How Much Energy Will a 13kW Solar System Produce?

A 13kW solar system can generate 40-60 kWh per day, depending on your location and the positioning of the panels. This translates to:

  • Over 2,000 kWh per month
  • More than 24,000 kWh annually

For context, the average Australian household consumes 18-22 kWh per day, making a 13kW system sufficient to cover daily energy needs and leave surplus energy for grid export, potentially earning feed-in tariff credits.

Is a 13kW Solar System Right for You?

Determining whether a 13kW solar system is suitable depends on several factors:

Energy Requirements

This system is ideal for properties with high energy demands, such as large households or small businesses.

Roof Space

Requires approximately 56.1m² of roof space when using 400-watt panels. Properties with limited space should consult a solar provider for customised solutions.

Budget and Payback Period

While upfront costs are significant, the potential savings and feed-in tariff earnings can offer a reasonable return on investment.

Incentives and Rebates

Take advantage of available solar rebates and feed-in tariffs to reduce initial costs and maximise savings.
