Turbine siting is always a compromise and can result in less than ideal winds. To reduce DC power losses in the power cables, most turbines in the Falklands operate at 48 V (50–60 A) but a few operate at 24 V (100–120 A).

Wind turbines have two main design categories: horizontal and vertical axis. The horizontal-axis turbine typically has a three-blade vertical propeller that catches the wind face-on. The vertical turbine has a set of blades that spins around a vertical axis. Each type has its advantages and disadvantages and is suited to different environments.
