Abstract :This research examines the efficiency of small-scale vertical axis wind turbines for energy generation on the Bitlis Eren University campus. Wind data analysis was conducted using Weibull and Rayleigh distributions, with the most suitable distribution identified through error analysis. Three vertical axis wind turbine models from the same manufacturer, with rated capacities of 600W, 1000W, and 3000W, were assessed for energy production potential. Error analysis results indicated that the Weibull distribution provided the best fit for the wind data. Based on this distribution, the annual mean wind speed was found to be 3.17 m/s, while the average power density reached 45.25 W/m². Analysis of the results indicated that, among the evaluated models, the 1 kW turbine exhibited the most favorable capacity factor, suggesting a more efficient performance relative to its rated capacity under the given wind conditions. In contrast, the 3 kW turbine yielded the highest total annual energy output, highlighting its potential for maximizing absolute energy generation despite having a lower efficiency ratio. These results suggest that small-scale VAWTs can be viable for rooftop installation in regions with similar wind characteristics, offering a supplementary energy source for institutional or residential use. The study provided insights that could inform local energy policy, particularly in promoting decentralized renewable energy systems and integrating wind energy solutions into urban infrastructure.
