10kW Solar System Brisbane: All Your Questions Answered

10kW Solar System Brisbane: All Your Questions Answered

Is 10kW Enough to Completely Power My Home?

A 10kW solar panel system has the capacity to generate an average of 44kWh per day, with higher production during the summer months and reduced output in winter. This level of energy generation is often adequate to fully power most homes, especially when paired with a suitably sized battery for nighttime energy usage.

Factors Affecting Energy Generation

The energy output of a 10kW solar system is influenced by various factors, including:

  • Home size
  • Energy consumption patterns
  • Solar panel and component efficiency

Tailored Solar Solutions for Your Home

When considering the suitability of a 10kW solar system for your home, it's essential to account for your specific energy requirements. Factors such as the number of occupants, household appliances, and heating/cooling needs can impact energy consumption.


Will I Have No Energy Bill with a 10kW Solar System?

Solar System Savings and Grid Connection Charge

If your daily energy consumption is under 44kWh, a 10kW solar system can significantly reduce your energy bills, but it's unlikely to completely eliminate them. Here's what you need to consider:

Energy Consumption

The more energy your household uses, the more you'll be able to offset with a 10kW solar system.

Electricity Cost

High electricity rates in your area can result in more significant savings with a solar system.

Solar System Efficiency

More efficient solar equipment will generate more electricity and lead to greater savings.

Solar System Performance

Factors like shading, orientation, and tilt can affect the system's energy output and your resulting savings.

    While a well-designed 10kW solar system can offset a significant portion of your energy bills, potentially reducing them by 50% or more, there will still be a connection charge of between $1.00 to $41.30 per day from the power company for grid connection. This means that you may still need to draw some electricity from the grid, especially during periods of high energy demand or when your solar system is not producing enough to meet your needs.

    What are the best solar panels for a 10kW solar system in Brisbane?

    We recommend REC, JA Solar, and Aiko for solar panels. However, we have access to all brands. If shading is a concern, Aiko is the best option. For long-term durability and the best price, JA Solar is recommended. If you prefer non-Chinese-made options, REC is an excellent choice.


    How Much Does a 10kW System Cost in Brisbane? How Much Money Can It Save Me?

    When considering the cost of a 10kW solar system in Brisbane, the potential savings largely depend on your level of self-consumption. The more energy you can directly consume from solar, the greater your savings. To optimise your consumption, we recommend the following:

    • Use timers for hot water and pools.
    • Set dishwashers and washing machines to operate in the middle of the day.

    These measures can contribute to annual savings ranging from $1500 to $2500, depending on your energy consumption patterns.


    Factors Affecting Solar System Cost

    • Brand and efficiency of the solar panels
    • Type and quality of the inverter
    • Inclusion of a solar battery storage system
    • Complexity of the installation, including roof type and structural modifications
    • Reputation and expertise of the solar installer


    Cost Estimate

    • A high-quality 10kW solar system in Brisbane typically costs between $8,000 to $12,000, inclusive of panels, inverter, and installation.
    • Prices may fluctuate based on market conditions, installation factors and changes in solar technology and equipment costs.


    Potential Savings

    • A well-designed 10kW solar system can save between $1,500 to $2,500 per year on energy bills, depending on energy consumption and electricity costs.
    • You may also be eligible for government incentives and rebates.



    • For a more accurate estimate of cost and potential savings, it's advisable to consult with a reputable solar energy provider, such as UV Power, in Brisbane.
