Wind power is one of the natural renewable energy sources which are constructed on specific area where There is plenty of the wind and it’s utilized to generate power. The atmospheric wind is first converted into mechanical energy and later to electrical energy. The modern windmills have been furnished with turbines that create a kinetic energy which is then converted to electricity. In an effort to improve the efficiency ofwind power generation, various technologies have been tested with an aim of increasing efficiencies of wind power such as flat detector 5, three-rotor savonious 6, fixed pitch angle variation 7, number blades in savonious 8. Another method employs the wind lens technology which is by far going to increase the generation of wind power energy 9–12. The system has been found to have a maximum energy generation efficiency potentiall of 59.3% called the Betz limit. But with the introduction of wind lens, the narrative is likely to change since the wind lens works by taking the idea of Betz limit and then placing focusing lens around the exterior circumference of the blades. The main aim of this wind lens is to create an area of low pressure behind and around the blades. This new technology has been tested and confirmed to increase the wind power generation efficiency by improving the operations of the blades computationally and experimentally 9–12. This research experiment is to study the effect of nozzle-lens diameter and blade number in low wind speed condition. A power output produced, RPM (Rotation per minutes) and TSR (Tip-Speed Ratio) furthermore is investigated.
