solar panels or wind turbine battery charging?

Most of the wind turbines are in the 200-400 watt range, and while nowhere near as loud as an open frame generator, needing to be on top of a mast you can't hide it behind something. They also require a stiff breeze to do anything, and a moderate wind to be anywhere near peak output. Solar is about as loud as the wind blowing past the RV, and does nothing in the dark, shadows, and very little in the rain.
