Abstract
This paper studies roof mounted savonius type Vertical Axis Wind Turbine systems with the goal of maximizing the efficiency and reducing the cost. The efficiency of the wind turbine depends on the material, shape and angle of the blade. So material plays an important role in the design of wind turbine. In this paper, Stainless Steel and Aluminum material are used to design savonius wind blades of 1 m height and 0.5 m chord length with 4 different arc radii. Modeling software Solid Works is used to model savonius wind blade and static structural and modal analysis of the Stainless Steel and Aluminum blades are done by using ANSYS Workbench software.

Summary
Savonius wind turbine is one type of vertical axis wind turbine used for converting the wind force into torque on a rotating shaft and electric power. The turbine consists of a number of blades vertically mounted on a rotating shaft. It is low cost and reliable, but efficiency is poor. This turbine is self starting and no pointing mechanism is required to allow for shifting wind direction. Sigurd Johannes Savonius invented this wind turbine in 1922. It was not widely used for many years. The Savonius rotor blade seems to satisfy these particular needs
