A Novel 10 kW Vertical Axis Wind Tree Design: Economic Feasibility Assessment

A novel, small-scale vertical axis wind turbine tree was designed using turbines combining both Darrieus and Savonius blades. We tested for economic viability using wind data collected at a site in Surat Thani, Thailand. The Weibull distribution and Monte Carlo modeling with financial indices (Level...

We found that monthly mean wind speeds varied from 2.35 m/s in October to 2.84 m/s in February, corresponding to a wind power of 28.43 W/m<sup>2</sup> and 42.68 W/m<sup>2</sup>.
