At this scale, two solar panels, so something like 1200 watt hours of energy per day I don't think you'll find a wind generator and tower to beat the price.

24 hour operation may not be requirement. Clean water stores just fine.

I was going to list a counter example of a place where wind would be a better idea, but all the cloudy places I can think of have rain, so they probably get water from that. It's a big world though, I'm sure lots of places have bad enough sun that the number of panels would make the cost tip in favor of wind.
