Figure 11.1: SWOT analysis
Weaknesses
DESIGN EVALUATION
1) Divergence of actual performance
2) Only designed for Class IV site
Threats
The items of the SWOT analysis are elaborated below
Strengths
1) Availability and price of permanent
magnets
2) Not all components are covered by the
present work
1) The HAWT concept is adopted on basis of through investigations in the conceptual
phase.
2) The direct drive principle makes it possible to omit the transmission, which would
otherwise complicate the design and the manufacturing process.
3) The use of prevailing materials, such as common steel and widely available wood
makes it probable that the wind turbine may be manufactured in most developing
countries.
4) Material selections may be altered and key components may be replaced without
compromising the overall design
