Cover Story: This paper considers the energy efficiency of a small wind turbine with a horizontal axis of rotation. The research focuses on the shape and inclination of the turbine blades (measurements) and the effect of the additional aerodynamic shields on the incoming air velocity (CFD analysis). The study has indicated that changing the shape of the blades can increase the analyzed wind turbine power by up to 35% while also presenting that adjusting their inclination can cause an increase of up to 16% compared to the initial installation position and a 66% increase in power comparing the extreme inclination of the tested blades. The results have shown that, to increase the wind speed, the best solution is to use a confusor–diffuser configuration, which, with increased length, can increase the air velocity by up to 21%.
