Nowadays, wind turbine became one of the largest energy suppliers of energy in world. The focal point in the wind turbine system is where the wind is harvested and converted into useable energy by the wind turbine blade. This study emphasized on determining the performance of continuous and slotted type of 5 meter diameter wind turbine blades for low wind speed in Malaysia. The Autodesk Inventor 2013 software was used as to develop the three dimensional model NACA 4412 airfoil blades with and without slot before evaluation of aerodynamic characteristics by using ANSYS software. This evaluation of aerodynamic characteristics of the slotted wind turbine blades with different slot configurations is believed could to benefit the material weight reduce its cost as it is constantly rising. Blades with lighter material would produce wind turbines with low rotational inertia and therefore would yield better energy performance at lower wind speeds. The aerodynamic results shows an increased value of lift coefficient with the increasing value of angle of attack (0 - 30).
