If there is an 11kW wind turbine, and a 15kW wind turbine. Why is the 15 kw wind turbine more expensive?
I know it seems like a basic question, but what exactly makes it more expensive? Is it only the generator? Or is there something less obvious that causes it to drive the turbine price higher, with higher power?
I am hypothesizing that the weight of the turbine might be the major factor that determines the price of the turbine, and not its generator capacity.
Any additional thoughts are welcome.
