Eco Whisper Turbine: Australian-made, small-scale wind power

Solar Choice, as Australia’s solar photovoltaic (PV) installation brokering service, does not ordinarily work with wind turbine installers or manufacturers, but both technologies are similar in spirit and offer many of the same benefits to their owners. This article is an overview of one of the wind turbine technologies available on the Australian market: the Eco Whisper Turbine.

The Eco Whisper Turbine is a competitively-priced, Australian-made horizontal axis wind turbine (HAWT) that is quieter and more compact than popular 3-blade turbines. Eco Whisper Turbines may be deployed to offset electricity loads in a variety of applications, including residential, commercial, industrial and manufacturing sites, as well as farms and urban locations such as schools.

Much like a rooftop solar panel system, the Eco Whisper Turbine has a long lifespan (20+ years) and is clean, fuel-free electricity generation option for those who are located somewhere with favourable wind conditions.

Eco Whisper Turbines: Product range

The Eco Whisper comes in two ‘sizes’: The Eco Whisper 325 (5 kilowatt (kW) in capacity), releasing in the 2nd half of 2013, and the Eco Whisper 650 (20kW in capacity). Over the course of a year, the turbines can generate up to 45,00 kilowatt-hours (kWh) and 11,250kWh of power, respectively.  These figures, however, represent peak capacity; actual output will vary with the wind wind speed and frequency of the location in question.

As a reference, the average Australian 3-person household consumes around 30kWh of electricity per day, or about 11,000kWh annually. This means that the Eco Whisper 650, in the right conditions, would be capable of powering up to 3 homes or a small factory. The 350 would produce enough power to significantly offset the power bills of a large home or an industrial shed.

  1. Hi

    We have a 2.5 kW solar system and I was wondering at the feasibility of having a wind turbine installed to supply the inverter with an alternative power source overnight when the solar isn’t working.

    What are the possible costs? What are the possible complications? What needs to be considered for the installation location?

    1. Hi David,

      About costs, you’ll want to approach EcoWhisper / RESAu directly.

      You’d probably need a separate inverter for the wind turbine as opposed to retrofitting it onto your existing inverter, which will most likely only work for solar panels. You’ll also want to have a survey done about the wind resources available in your area – something that the EcoWhisper folks might be able to help you out with. However, it’s unlikely that solar + wind will meet all of your needs 100% of the time, so it might make sense to look into battery storage for both solar and wind, as this might ‘fill in the gaps’ and ensure that you have energy available when you need it.

      Best of luck with your system!

  2. We are registered marketing company, manufacturers representatitive and services provider in Cotonou,

    Republic of Benin in West Africa.

    With our involvement in resettlement of thousands of traders to a new permanent site, and posing as serious challenges the issue of electricity at this new site.

    Thus, we are much interested and ready to import the basic solar/wind turbine energy kits for Africa. But due to our own special peculiarity of the nature of this our market settlement of thousands different sheds, we will need a special design that is only peculiar to our company, basic solar/wind turbine energy kits for the following applications;

    1, Solar panel and wind turbine devices that can generate energy to store in the battery with the connector to other devices will form the complete set of the basic solar/wind turbine kits for our company.

    2, 12hours solar/turbine power and store back up energy system.

    3, strong and resistant component that can last long.

    4, durable and long lasting battery that can store energy for a long period of time.

    5, ideal for lighting system and all kind of home and offices appliances like fan, audio/video equipment, computers, mobile phone charging and others.

    Hence, with the above applications, please inform us the details descriptions of the composition of all the component parts that made up of this particular type of basic solar/wind turbine energy kits that we needed. Also, of what capacity or grade type of solar/wind turbine kits and battery that will be suitable and good for this type of our needed solar/wind turbine kits.

    Please be noted and understood of our intention and desire to build up a long partnership relationship with your company, with constant and regular shipment that will last for a long period of time.

    Therefore, we need good and standard quality that will not disappoint us in the market because, with our position and reputation in our market we must only sell and supply high quality standard and efficient solar/wind turbine kits in the market.

    With this, we will need your best and most competitive offer prices in CIF Cotonou port, Republic of Benin, West Africa. Your conditions of sales and services, and a complete set of this type of kits for physical samples for us to evaluate and test the quality standard before our first trial order.

    Awaiting your urgent reply

    Thanks & best regards

    1. Hi Afeez,

      Thanks for your interest. We would advise contacting EcoWhisper / RESA directly via the details in the article. We (Solar Choice) operates only in Australia and do not keep any stock ourselves.

      Best of luck!

    1. Hi David,

      Please use the contact details at the bottom of the article for enquiries about the EcoWhisper – we do not stock it (or hold any stock, for that matter) and the installers in our network generally only deal in solar PV and energy storage. This article was written as an informational piece about an interesting technology.

  3. I saw your interesting product and just wanted to know the weight of a 5kva system and the cost. I am scouting for a wind generator to install at my rural home in ZImbabwe. If it does work for me, I hope I can be your agent there as the country is experiencing a serious power supply deficit.

    I hope to hear from you soon…

    1. Hi Shepherd,

      Please get in touch with EcoWhisper / RES Australia directly using the contact details at the bottom of the article. We do not offer this product ourselves – this article was written as an informative overview of what they offer.

      Best of luck!

  4. Liked your presentation. How is your business doing? Are you having any 5 kW turbine ready yet.
    What would the price be for one? I am not sure if we could afford it yet, but am interested.

    Thank you very much in advance.



    1. Hi Felix,

      Please contact Ecowhisper / RES Australia direction on the contact details listed above in the article. Solar Choice does not stock their products.
