bigger blades more power.
Probably power is proportional to blade length squared, ie, proportional to the area swept by the blades.
Eg, GE 3.5 MW has swept area of 9677 m²
GE 1.5 MW has swept area of 3904 or 4657 m² (2 different models)

The site below has a great, comprehensive overview of all things wind. It has an answer on almost any question about size, placement, speed, etc.
