FAQ's of Savonius Wind Turbine:
Q: How does the Savonius Wind Turbine operate in low wind conditions?
A: The Savonius Wind Turbine is engineered to start generating power at a cut-in wind speed of just 2.5 m/s, making it effective in areas with moderate wind speeds. Its double S-type curved blades capture wind efficiently, ensuring steady power output between 2 and 20 m/s.
Q: What are the main benefits of using a vertical axis design like the Savonius turbine?
A: Vertical axis turbines like the Savonius are less sensitive to wind direction, operate quietly (<40 dB), and are easier to install on rooftops or ground mounts. Their low start-up speed and robust construction offer long-term, reliable small-scale power generation even in variable wind environments.
Q: When is annual maintenance recommended for this wind turbine?
A: Although the Savonius Wind Turbine is designed for low maintenance, an annual inspection is advised to ensure optimum performance and longevity. This typically involves checking fastenings, inspecting the blades and shaft, and cleaning any accumulated debris.
Q: Where can the Savonius Wind Turbine be installed?
A: This turbine is suitable for both ground and rooftop installations, making it a versatile choice for off-grid areas, educational institutions, small-scale generation sites, and remote locations. The compact design (1.2m x 0.8m x 2m) allows for installation in limited spaces.
Q: What equipment and accessories are included with the Savonius Wind Turbine?
A: Each unit comes equipped with a mounting stand, generator, and control electronics. The robust build and anti-corrosive powder coating ensure reliable operation in varied climates without the need for additional extensive supporting infrastructure.
Q: How is the output power affected by wind speed and turbine design?
A: Output power for this turbine ranges from 200W to 1 kW and depends on the local wind speed, overall turbine design, and customization such as the number of blades. Maximum performance is achieved at higher sustained wind speeds closer to the turbine's upper working limit of 20 m/s.
