HAWT VS VAWT

Small horizontal wind turbines emerge as the more economical choice due to their capacity for generating higher electricity, benefiting from aerodynamic advantages and regulatory simplicity. These turbines, prevalent in the market, are widely accepted and often certified under the rigorous standard. Their efficiency and ease of regulation make them the preferred option for electricity generation.

On the other hand, vertical Savonius rotors, while exhibiting lower efficiency, find niche applications in specific contexts, such as pumping water. However, a major drawback is the scarcity of manufacturer-independent references, leaving potential buyers with limited information. This lack of transparency impedes decision-making regarding the effectiveness and economic viability of these rotors for widespread electricity generation in inland areas.

Similarly, Darrieus rotors, distinguished by lift efficiency, face challenges related to pronounced vibrations and difficulties in storm protection. The limited ability to turn a vertical wind turbine out of the wind, a feature found in horizontal counterparts, further complicates their use.
Despite these challenges, both vertical designs share the advantage of easy maintenance, with machine components conveniently located on the ground. The aesthetically pleasing designs of many Darrieus rotors contribute to their positive reception in certain settings.
