Townsville experiences about 8.5 hours of sunshine per day on average, making it a major hub for solar power. As more and more people are turning to solar energy, the 10kW system has become very popular for medium-large sized homes.

Installing a 10kW solar power system in Townsville costs about $7,500 to $9,000 on average. The cost can go up to $12,000 or more for high-end brands.

The system’s actual cost depends on your location, solar panel quality, and the orientation/complexity of your roof.

10kW Solar System Output in Townsville

Townsville receives an average of 8.5 sunshine hours per day. So, a good-quality solar system generates about 40kWh to 44kWh per day.

Several factors may affect the daily output of your solar power system. These include:

  • Shading from buildings and trees
  • Climatic and weather condition
  • Orientation of the solar panels
  • Roof angle
  • Quality of the panels and other components
  • Wear and tear

The 10kW solar system is suitable for large households with above-average electricity consumption and small businesses looking to cut down electricity bills by 45% to 70% or even more, depending on your daily power needs.

What Is the Payback Period of a 10kW Solar System in Townsville?

On average, a 10kW solar system takes about 3 to 5 years to pay for itself. However, this depends on your consumption.

If you use most or all of the power generated by your solar system, the system’s payback period will be shorter. However, if you use lower than average of the energy your system generates, the system may take a longer time to pay for itself.

This is because all your surplus power will be sent back to the grid and the feed-in-tariff rate you get for that is pretty little- 6.6cents per kWh in QLD.

How Much Can a 10kW Solar System Save You in Townsville?

Townsville receives more than 5 hours of sunshine per day and is one of the best places to install solar power. The amount of money your solar system can save you depends on two factors. These include:

Self-Consumption Rate

An average 10kW solar power system generates between 40kWh to 44kWh every day.

Assuming you pay an average of 25c tariff to your electricity retailer, a 10kW system can save you about $10 per day or $300 per month if you use all the power your system generates. So, by the end of the year, you can save between $2,000 to $3,600.

Solar Feed-In-Tariffs

If you cannot use all the power generated by your system, the extra energy will be sent back to the grid at a rate of about 5cents to 10cents per kWh. In such a scenario, your annual savings will reduce by the amount of the power you are not consuming.

In short, if you use most of your solar power, you will save about 25c per kWh(cost of your electricity). If you send most of your solar power to the grid, you save about 10 cents per kWh (flat rate for FIT).

What Is the Rebate Amount of a 10kW Solar System in Townsville?

The Australian government solar panel rebate in QLD, widely known as the Small-scale Renewable Energy Scheme, awards Australian residents rebates for installing solar panels.

Typically, the rebates vary depending on your STC zone. There are four STC zones in Australia, based mainly on solar radiation and other critical factors.

Townsville, QLD, is in Zone one and receives 124 STCs for a 10kW solar system. The STC price has been jumping between $35 and $40 for the past few years. So, for a good-quality 10kW solar system, you will receive a rebate amount of about $4774.

How Much Roof Space for a 10kW Solar System?

A quality 10kW solar system requires between 30 to 40 solar panels, but the exact number depends on the wattage of the panels.

Each panel measures 1.675m X 1m, so you will need approximately 60 to 80 sqm for your system.

If you have limited space on your roof, you can install fewer highly-efficient panels that generate more power. However, you must be willing to pay a premium rate for such panels.

10kW Solar System in Townsville With Battery Backup

If you are planning to go off-grid, you will need battery storage to store the excess power from your solar system. A 10kWh generates about 40kWh per day, so you will need a battery capacity of approximately 28kWh.

Battery storage is quite expensive and can increase the payback period of your system.

On average, a 28kW battery system will cost about $27,500 without an inverter and up to $30,000 with an inverter/charger.

If you include the cost of installing your 10kW solar system, the overall cost of the solar and battery system can go up to $45,000+.

More so, solar batteries have a lifespan of between 5 to 15 years. So, you will need to replace your battery system at an extra cost to match the lifespan of your solar system.

What Are the Benefits of Installing Solar Power in Townsville?

Solar power comes with several benefits that cannot go unnoticed. These include:

  • Impressive Returns On Investment. You can save at least $2,000 on your electricity bills per year.
  • Reduced power costs. Solar power helps you reduce about 45% to 70% of your daily electricity usage.
  • Using battery storage. You can increase your power savings by storing excess power in a good-quality battery system.
  • Saving the environment. Solar power helps you conserve the environment, which is a good cause, especially if you are an environment enthusiast.
