Is this safe to do or will I fry the wind turbine generator? What kind

Nah, I don't think you'll fry the generator with the DC load. If the turbine can't supply full power
to the element, it will just turn slower or not at all.

Actually, I don't think you really need any dump load with this sort of system. All that will happen
is that the solar cells will get hot and the turbine will spin at a rapid rate. Perhaps a mechanical
arrangement to turn the turbine out of the wind if it starts spinning too fast.
