The objective of this research is to design a Savonius wind turbine with a horizontal axis optimized for low wind speeds and to measure the power output and efficiency generated by the turbine. The research methodology employed in this study is experimental. The turbine design incorporates 0.3 mm thick transparent PVC as the material for the turbine blades, with a configuration featuring three helical-shaped blades measuring 93 cm in length, 16 cm in width, and having an 8 cm radius. The turbine frame is constructed using 20 mm×20 mm aluminum profiles, with dimensions of 100 cm in length, 30 cm in width, and 35 cm in height. Data collection involves conducting 10 repetitions for each wind speed variation ranging from 1 m/s to 10 m/s. The highest power output increase occurred at a wind speed of 6 m/s, with a power of 0.46 Watt increasing by 0.13 Watt. It resulted in an average shaft rotation of 132.28 rpm, average power output of 0.27 Watt, and average efficiency of 7.10% for wind speed variations ranging from 2 m/s to 6 m/s. © 2024 Author(s).
