Development of a roof-mounted stand-alone wind turbine system for house-hold power generation

Abstract

In recent years, the development of sustainable energy sources has attracted increasing interest due to worries about the environmental effects of greenhouse gas emissions. Renewable energy and technology may provide a solution to the persistent environmental issues that developing nations are currently experiencing. In this work, it has been demonstrated that the design, analysis, and implementation of the newly developed small roof-mounted stand-alone wind turbine systems for household energy production. It is specially designed for sites with low altitudes (12 m above ground) and low wind speeds (range of 1–12 m s−1). The wind turbine system involves the mechanical design of the 3-blade rotor and its installation on a micro-capacity and self-contained 325 W wind turbine. The experimental analysis reveals that the peak power coefficient (CP) is quite good, about 0.13, and the output power is 43.75 W. The comparative analysis is also done to validate that the results are consistent with micro-capacity systems that have been tested under similar conditions. This work provides insight into the development of roof-mounted stand-alone wind turbine systems, which have a lot of potential for green applications and to make up for people who don’t have access to electricity.
