Ultra Low Speed Wind Turbine For Onshore Rural Area Usage


Renewable energy is becoming increasingly important due to environmental concerns and the need for sustainable power. This project aims to enhance the efficiency of horizontal-axis wind turbine solutions by optimizing blade design and material selection.

The goal is to contribute to addressing climate change and resource scarcity by advocating for clean energy. The project focuses on making renewable energy sources more accessible and efficient. The ultra-low-speed wind turbine system can be employed to extend the availability of essential rural infrastructure and quality basic services, thereby expanding electricity coverage.

The wind turbine blade design project incorporates an innovative approach, highlighted by the intellectual property titled "An Improved Aerofoil Body," protected under a patent in Malaysia (Reference Number: PI2019004596). This patent, owned entirely by Universiti Putra Malaysia, underscores the unique nature of the blade's aerofoil body enhancement. The design's legal status remains active, marking a significant advancement in the field of renewable energy.

Wind turbine technology featuring the Tubercle Leading Edge (TLE)-modified Horizontal Axis Wind Turbine blade showcases an innovative design and wind power system that optimizes aerodynamic efficiency. The uniqueness of this invention lies in its advanced wind turbine blade design, which enhances the system's start-up speed and enables higher energy storage at low wind speeds.

It is suitable for areas with relatively mild and consistent winds. Carbon fiber, known for its longevity, offers a high strength-to-weight ratio and superior mechanical properties for the wind turbine blade. The existing technology, represented by wind turbines, faces several significant problems and disadvantages. These include inefficiency at low wind speeds, limited energy harvesting potential, and cost-effectiveness barriers.

The described invention's unique blade design offers a promising solution to these challenges by improving wind turbine efficiency in low-speed wind conditions, reducing costs, and expanding the feasibility of clean energy generation in diverse environmental settings.


  • Simplicity and Portability: The compact design is easily integrated, featuring durable blades, and its portability simplifies deployment.
  • Cost-Effectiveness: The design's low maintenance requirements translate to cost savings in the long term. Lightweight blades also extend the generator's lifespan.
  • Enhanced Energy Production: The wind turbine's light blade system contributes to higher energy production and efficient storage.
  • High Efficiency: Operating effectively even at low wind speeds (2 m/s), the turbine remains functional in diverse weather conditions and boasts resistance to lightning, prolonging its operational life
