FAQs

  • 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?

    COSTS

    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

    SYSTEM SIZE ESTIMATED PRICE RANGE
    (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

     

    SAVINGS

    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?

    When choosing a solar or storage retailer and/or installer, it pays to do a little research. The Clean Energy Council recommends choosing an Approved Solar Retailer who has signed on to the Solar Retailer Code of Conduct and only uses designers and installers who are accredited by the Clean Energy Council.
