With rising electricity costs and the growing interest in sustainable energy, more and more homeowners are considering installing a solar system in their home. A 6.6kW residential solar system is a popular choice for many homeowners, and for good reason. In this post, we will discuss the top five reasons why homeowners should consider installing a 6.6kW solar system and the key features of such a system.

Top 5 Reasons to Install a 6.6kW Residential Solar System

  1. Lower Energy Bills: One of the biggest benefits of installing a 6.6kW residential solar system is that it can significantly reduce your energy bills. By generating your own electricity, you can reduce your reliance on the grid and avoid paying for expensive electricity from your utility provider. Depending on your energy usage and the size of your solar system, you could potentially save thousands of dollars on your electricity bills each year.
  2. Increased Home Value: Another major benefit of installing a 6.6kW residential solar system is that it can increase the value of your home. Solar systems are becoming more popular and homebuyers are willing to pay a premium for homes with solar systems installed. A solar system can also make your home more attractive to potential buyers and increase the likelihood of a quick sale.
  3. Environmental Benefits: A 6.6kW residential solar system can help reduce your carbon footprint and contribute to a cleaner environment. By generating your own electricity from a renewable source, you can significantly reduce your greenhouse gas emissions and help mitigate the effects of climate change.
  4. Government Incentives: In many parts of the world, governments offer incentives to homeowners who install solar systems. These incentives can include rebates, tax credits, and other financial incentives. By taking advantage of these incentives, homeowners can significantly reduce the upfront cost of installing a solar system.
  5. Energy Independence: By generating your own electricity, you can become more energy independent and reduce your reliance on the grid. This can provide peace of mind during power outages or grid failures, as your solar system can continue to generate electricity even when the grid is down.

Key Features of a 6.6kW Residential Solar System

  1. Solar Panels: A 6.6kW residential solar system typically consists of 20-24 solar panels, depending on the wattage of the panels. The panels are typically mounted on the roof of the home and are designed to absorb sunlight and convert it into electricity.
  2. Solar Inverter: The solar inverter is responsible for converting the DC electricity generated by the solar panels into AC electricity that can be used in the home. A high-quality inverter is essential for the efficient operation of a solar system.
  3. Monitoring System: A monitoring system is typically included with a 6.6kW residential solar system. This system allows homeowners to track the performance of their solar system and monitor the amount of energy generated and used.
  4. Battery Storage: Battery storage is becoming an increasingly popular feature of solar systems. Battery storage allows homeowners to store excess energy generated by their solar system and use it during times when the sun is not shining.

6.6kW Solar System Pricing

The cost of a 6.6kW solar system can vary depending on a number of factors, including the brand and quality of the solar panels and inverters, the complexity of the installation, and the location of the home.

On average, a 6.6kW residential solar system in Queensland can cost anywhere from $5,000 to $10,000, including installation.

Another factor that can impact the price of a 6.6kW solar system is the quality of the solar panels and inverters.

When considering the cost of a 6.6kW residential solar system, it’s important to weigh the upfront costs against the long-term savings. While the initial investment can be significant, the energy savings and government incentives can provide a significant return on investment over time. Additionally, installing a solar system can increase the value of a home and provide a clean and sustainable source of energy.

Overall, the cost of a 6.6kW residential solar system can vary depending on a number of factors, but the potential energy savings and environmental benefits make it a worthwhile investment for homeowners looking to reduce their energy bills and carbon footprint.

How to Choose a Qualified Solar Retailer

Choosing a qualified solar retailer is essential for ensuring that your solar system is installed correctly and that you are getting the best value for your investment. Here are a few things to look for when choosing a solar retailer:

  1. CEC Accreditation: The Clean Energy Council (CEC) is the peak body representing Australia’s clean energy sector. Look for a solar retailer that is CEC accredited, as this ensures that the company meets high standards of quality and safety.
    • Reviews and Testimonials: Look for online reviews and testimonials from past customers. This can give you an idea of the quality of service and workmanship provided by the solar retailer.
    • Warranty and Guarantees: Look for a solar retailer that offers a warranty and guarantees on their products and services. This can provide peace of mind knowing that your solar system is protected.
    • Price and Value: Compare prices and value for money between different solar retailers. Look for a retailer that offers competitive pricing while still providing high-quality products and services.

    • How does solar work?

      When the sun is shining, solar panels convert sunlight into DC (direct current) electricity. The solar inverter converts this electricity into AC (alternating current) power for use in your home. Your home appliances (fridge, dishwasher, pool pumps etc.) use this power instead of drawing power from the electricity grid.

      Any excess electricity generated by solar panels but not used by appliances is sent back (exported) to the electricity grid or used to charge a solar battery. Electricity Retailers pay a feed-in tariff for any electricity sent back to the grid.

      Solar generation, consumption and export is tracked and recorded through a smart meter, providing the data for electricity billing.

      Solar systems are most effective when they are well positioned (north-facing is optimal, but not essential) and exposed to enough sunlight without obstruction by shade caused from trees, power lines or other structures.

    • What size solar system is appropriate for my home?

      The appropriate size of a solar system for your home depends on various factors, including your household’s energy consumption, roof size, and the amount of sunlight your home receives. DE Energy Solar’s team can evaluate your energy usage and recommend a system size that is tailored to your specific needs.

    • What is the cost of installing a solar system with DE Energy Solar?

      The cost of installing a solar system with DE Energy Solar varies depending on the size and type of system, as well as other factors such as your location and electrical setup. Our team will provide you with a quote tailored to your specific needs and budget.

    • Do I qualify for solar rebate in QLD?

      If you are the homeowner.

      Any purchase of solar panel system will qualify for the rebate so long as the solar modules and solar inverter approval by the Clean Energy Council and; a CEC accredited installer performs the installation.

    • Does DE Energy Solar offer any government incentives or rebates?

      Yes, we can help you navigate government incentives and rebates that may be available for solar system installations. We will work with you to maximize your savings and ensure you take advantage of any available incentives.

    • What is Solar Feed-In Tariffs (FIT)?

      A feed-in tariff is the rate you are paid for any electricity generated by your rooftop solar system that is fed back into the grid.

      Feed-in tariffs are generally available for residential systems and do not necessarily extend to commercial customers. However, in most cases, commercial customers should be able to negotiate a rate with their electricity retailer.

      Almost all feed-in tariffs offered now are ‘net’ feed-in tariffs. This means that the electricity produced by your solar panels will be used in your home first, and you will only be paid for excess electricity that is exported to the grid.

      Feed-in tariffs differ from state to state and from retailer to retailer. In some states the government regulates a minimum rate, and in other states it is up to you to negotiate a deal with your electricity retailer.

      There is no government-regulated minimum retailer payment in New South Wales or southeast Queensland. It is worth shopping around to find out which electricity retailers offer the best rates for solar customers.

    • What if something goes wrong?

      If you have an issue with any solar product while it is under warranty, you should first contact your solar retailer to have the product replaced or repaired. If you are unable to contact your retailer, contact the manufacturer. Contact details should be provided on the warranty documentation.

      If you are not happy with the response you receive from your solar retailer, you can lodge a complaint with the relevant Fair Trading or Consumer Affairs in your state or territory. They can negotiate on your behalf and arrange mediation where necessary.

    • What should I do if the company I bought my solar system from has gone out of business?

      If your solar retailer has become insolvent and you are unable to contact the manufacturer, you can lodge a complaint with the solar retailer’s administrators. You can send out if a company has become insolvent via the Australian Securities and Investments Commission (ASIC) website or by phoning 1300 300 630.

      Your local Fair Trading or Consumer Affairs may also have information about the appointment of external administrators for insolvent companies. Likewise, if the manufacturer has
      gone into administration, you can lodge a complaint with the company’s administrators. As a consumer, you may become an unsecured creditor. If the external administrator fails to deal with your queries or complaints, you can also lodge a complaint with ASIC on 1300 300 630.

    • How much solar panels cost me and am I REALLY saving Money by going solar?


      The cost of installing a solar system can vary widely and is affected by a range of factors from where you live, the retailer or installer you choose, the warranties available, and the technology and size of your system.

      The major factors which will affect the price of a solar system are:

      1. Government rebates and incentives
      2. Contractor installation costs
      3. Type and number of panels
      4. Type and size of inverter
      5. Type of framing equipment and other system components
      6. Height and accessibility of roof and whether it is tiled or metal or concrete
      7. Any after sales service agreements

      Keeping the above variables in mind, these tables provide an approximate guide on the price range for solar systems in Australia’s major capital cities. Government rebates are included in these figures. Please note that the market costs change quickly so these numbers are illustrative only.

      Estimated prices for residential solar systems

      (Out of Pocket)
      2 kW $2,800 – $5,600
      3 kW $2,900 – $6,950
      4 kW $3,400 – $7,900
      5 kW $3,500 – $9,500
      10 kW $7,600 – $14,100



      There are numerous factors that affect your suitability for solar and the period it will take for your system to pay for itself.

      The amount of money your household will save on power bills by going solar is affected by several factors, including:

      Your energy consumption and the size of your solar power system – if you use more power than your system can produce, your savings will be reduced. It’s important to choose the correct system for your needs.

      Your feed-in tariff – this is the amount your electricity retailer pays you for any excess power your solar panels generate.

      Your usage patterns – solar panels can only generate electricity while the sun is shining. This means that households that use a lot of power during the day may attract greater savings than those that consume most of their power at night. However, you will still receive a feed-in tariff for any excess electricity you generate during the day.

      Where you live – some areas of Australia receive a lot more sunlight than others, so a solar system in Brisbane will usually generate more power than one in Hobart.

    • How do I choose a solar retailer?
