Because a wind turbine is limited to the area of the swept blades, and larger turbines can reach the faster winds that occur higher off the ground, large turbines are MUCH more effective than small ones. Turbine blades that are twice as long can capture four times as much wind, and the tops of those blades capture faster wind, too. On the other hand, ignoring integration and installation costs, solar panels scale linearly with size. So small solar makes much more sense than small wind.
