Design and manufacturing hybrid solar-wind prototype for clean energy home supply in Baghdad

Abstract

This paper presents a design procedure and manufacturing of a small hybrid solar-wind turbine type Savonius vertical axis wind turbine (VAWT) compensated with PV panel. The design of Savonius wind turbine (SWT) depend on modified blade shape model according to site condition in Baghdad city with wind speed 3 m/s. The sizing of photovoltaic (PV) system depends on required load (400 W) for lighting. PV panel tilt angle optimized according to Baghdad city location at (latitude 33°20′). Mathematical models were programmed by MATLAB to predict the solar energy incident on the surface all day of the year at angles from (0-90o). The monthly optimum tilt angle can vary significantly during the year between 18o at summer to 65o at winter seasons. The wind turbine can provide 10%-25% from total clean energy especially at cloudy or dusty days with received low solar radiation.
