Abstract: The growing need to have sustainable and decentralized energy systems has pushed the study of wind energy systems that can effectively perform at the low wind speed. The VAWTs are especially the right choice under such conditions because of their omnidirectional wind acceptance and simple structural design. Nevertheless, traditional Savonius and Darrieus turbines are limited in nature when they are used in isolation. The design and construction of a hybrid Savonius-Darrieus VAWT with the ability to Self Start like the Savonius rotor and high efficiency-based performances of the Darrieus rotor is presented in this paper. The turbine itself is made of low-cost materials, including sheets of metal blades and L-angles of shelter in mild steel. There is a spur gear mechanism that increases the speed of the shaft rotation so that it may allow effective coupling with the dynamo that runs on DC. Generation of this electrical power is proved by using DC LED light as a proof of concept. Low-speed under wind conditions provide experimental performance from low wind conditions, which prove stable operation and dependable energy production. The presented hybrid turbine will be a cost-effective and environmental-friendly solution that might be applied to domestic, rural and off-grid renewable energy sources.
