As an outcome from the continuous hybrid renewable energy research, an innovative outdoor lighting system powered by a shroud-augmented wind turbine and a solar panel was installed in the KL campus of University of Malaya (UM). This hybrid green energy system is a compact design that harmoniously integrates a vertical-axis-wind-turbine (VAWT) with the novel omni-direction-guide-vane (ODGV), solar panel and LED lighting system. Consisting of several guide vanes, the ODGV is carefully designed and placed to surround the VAWT for wind power augmentation where the oncoming wind is guided through the ODGV. This will create a venturi effect that increases the wind speed before the wind-stream interacts with the turbine blades. Furthermore, the unique design of the ODGV that shrouds the wind turbine rotor provides a safer and more secure environment for maintenance workers and the public.

Ultimately, the ODGV overcomes the low wind speed challenge in the tropics by guiding and increasing the speed of the wind from all directions radially through the guide-vanes before entering the VAWT at center portion. To harness power from the sun, a photovoltaic panel is mounted on the top surface of the ODGV for solar energy generation. The green energy generated from this wind-solar hybrid system is utilized to power the outdoor lighting system.

The team led by Dr. Chong Wen Tong was awarded a Pre-commercialized Prototype Fund to develop and install the product at suitable locations in the campus. The fund was provided by UM via UM Center of Innovation and Commercialization (UMCIC). The first unit was installed next to the outdoor gymnasium, opposite 1st Residential College. This unit will serve as the first full-scale trial and as a showcase unit of the product. Improvements on the design and features will be included in the next units. For the commercialization of this product, a Memorandum of Understanding (MoU) has been signed between UM and a private company, Master Shanghai Turnparts Sdn. Bhd. (MSTSB). MSTSB has provided great assistance in enhancing the product. The second unit of the product is currently in the final stages of fabrication and testing.

The product is protected by three intellectual properties and a trademark, all of which is owned by UM. It also has won several awards in local and international exhibitions. With a motto 'Lighting-up UM', the team aims to provide a sustainable solution for energy efficient and quality lighting powered by wind-solar hybrid renewable energy sources.

Summary of the product

The product is a part of an UMRG project led by Dr. Chong Wen Tong. The product is called "Eco-GreenergyTM Wind-Solar Outdoor Lighting System" and it is self-sustained, i.e. powered by the shrouded vertical-axis-wind-turbine generator and solar PV panel. The novelty of the product is achieved through the wind power augmentation of the guide-vanes assembly known as the omni-direction-guide-vane (ODGV). The guide-vanes can be made from clear and translucent material to act as light-plates. Moreover, logos or symbols can be engraved on these plates for showcasing purposes. The solar PV is positioned at the top portion of the ODGV to avoid interference resulting from shadow. The batteries and the controller are stored at the top of the pole and below the ODGV to avoid vandalism or flash floods. The overall "clean" impression of the product compared to other conventional wind-solar lamp posts serves as an added advantage for this product.
