Big power, Small impact

Why small wind?

Small wind is an ideal way to produce clean, renewable energy in off-grid or fringe of grid (FOG) scenarios. In many situations customers cannot economically add additional solar PV modules and batteries to fulfil their power requirements. In this situation small wind turbines generate into off-grid or retail markets where the value of energy is higher. Installing a small wind turbine helps you lower monthly expenses and reduce carbon emissions.

Wind energy provided by a small wind turbine

Is complementary to existing solar PV generation

Can increase renewable fraction of a diesel/solar/wind hybrid system

Is able to generate at night and during rainy seasons

Keeps batteries trickle charged, which improves cycle-life and battery wear and tear

Has a greater output than solar PV, when appropriately sited

Reduced theft issues compared to ground installed solar PV

Suitable applications for small wind

Speak with our sales team

Telecommunications

Our Hyland 920 can be fitted directly to telecom towers and their existing power system with our ‘plug-and-play’ design. Telecom towers are often located on hill tops and are free of trees and other obstructions - this creates the perfect scenario for small wind turbines. The addition of wind energy can usually make the system 100% renewable.

Broadband and TV Networks

Like telecommunications companies, broadband and TV networks must transmit their data across Australia. This is primarily done through ‘line of sight’ data transmission using towers located on hill tops. Similarly, our Hyland 920 is built for this application and can easily integrate with the existing power system.

Agriculture

The rise of ‘smart farming’ has introduced a need for power and data in remote locations. Wind energy is the perfect companion for solar/battery setups to ensure you have power even when the sun isn’t shining.

Mining

Mining is an energy intensive exercise where critical communications systems must always remain online. The addition of wind energy to your power system helps to prevent downtime and protect against disaster. Energy resilience is a must.

Remote Monitoring and Data Loggin Sites

These systems often require only small amounts of energy to stay online. The addition of our Hyland 920 and a suitable battery will solve all of your power problems.

Our proven wind turbine technology

The Diffuse Energy technology was invented at the University of Newcastle, Australia - and leverages over 20 years of international peer-reviewed small wind turbine research . Our innovative intellectual property lies in the design of the “diffuser”, an aerodynamic ring that surrounds our turbine. This diffuser maximises the natural wind resource to unlock efficiency gains. Our Hyland 920 wind turbine has an operating efficiency of 42%, which can reduce your carbon footprint by more than 1 tonne per year per turbine. This is a significant improvement compared to existing market products.

Frequently asked questions

Why small wind?

Our world is speeding towards a future powered by renewable energy. But what happens when you can’t connect to the renewable electricity grid? It’s a serious, and often overlooked problem. Small wind is an ideal way to produce clean, renewable energy in off-grid scenarios. The natural wind resource complements solar generation, especially when coupled with a battery system. In many situations customers cannot economically add additional solar PV modules to fulfill their power requirements. Installing a small wind turbine helps you lower monthly expenses and reduce carbon emissions. The turbine:

  • Is complementary to existing solar PV generation
  • Is able to generate at night
  • Keeps batteries trickle charged, thereby improving cycle life.
  • Have a greater output than solar PV, when appropriately sited.

What applications are suitable for small wind turbines?

Our technology has been designed in direct consultation with leading wind energy experts and off-grid customers. These customers have prohibitive space restrictions for solar arrays due to small site footprints and are therefore reliant on diesel generation. Additionally, there is a significant cost and risk in supplying diesel to these isolated locations.

Our turbines work for:

  • Telecommunications, broadband and TV networks
  • Agriculture
  • Mining
  • Remote monitoring and data logging sites

Ideal locations include, open, exposed, and elevated areas free from obstacles and buildings.

What wind resource is available at my site?

Determining the site wind resource can be a challenging endeavour which is why Diffuse Energy will help with establishing the ideal position for your turbine. We have access to state-of-the-art wind resource modelling tools.

Why choose the Hyland 920?

The Diffuse Energy technology was invented at the University of Newcastle, Australia - and leverages +20 years of peer-reviewed small wind turbine research. Dr Joss Kesby and Dr Samuel Evans received their PhD’s within the wind turbine research field. The core team has close ties to the university to ensure ongoing  development of our technology. Few small wind manufacturers can claim this depth of expertise. 

Besides our market-leading efficiency, our turbine features; a plug-and-play electrical system for 48 VDC telecommunication sites, provides improved safety and reduced noise during operation while being compact in size to facilitate site retrofit on existing towers.

We have carefully designed our turbine and chosen materials to give it a long operational life of 20+ years.

Is the Hyland 920 designed to be safe?

The Hyland 920 leverages over 20 years of research and development at the University of Newcastle, Australia. Mechanical components have been designed in accordance with international small wind turbine design standard IEC 61400.2-2013. State-of-the-art computer aided engineering software has been used to verify the wind turbine components. Wind loading has been calculated as per AS1170.2 for Category D wind speed with a return rate of 50 years. Composites used in construction have a minimum rated UV exposure life of 20 years.

What about wildlife safety?

Studies have shown that there is little evidence that wind turbines pose a significant danger to birds or bats. Diffuse Energy’s novel wind turbine technology may assist wildlife in avoiding wind turbines. Our rotor is enclosed by an aerodynamic shroud which by design prevents exposure to the blade tips. Also, the higher rotational speed of small wind turbines is a larger deterrent for animal interaction.

What is the noise output of the Hyland 920?

Noise output of modern small wind technology is low. When assessing noise levels of existing wind turbines certified by the Small Wind Certification Council (SWCC) average noise levels are reported at 45 dB(A) for an open-blade horizontal-axis design. Noise of this level is deemed within the range of “quiet radio music” by Safe Work Australia.

What about solar PV modules?

Recent reductions in cost of solar PV and batteries have seen widespread uptake. This is an exciting opportunity to reduce the entry barrier to renewable energy. Many of our customers have reached maximum renewable penetration limits with solar PV alone and see the oversizing of solar PV modules for redundancy as costly.

Our wind turbine is designed to complement existing generation. It is easily retrofittable to existing power systems, meaning that the total system cost is reduced.
