I do not recommend keeping it on your lens at all times, since a polarizing filter slows your camera down by reducing the amount of light that passes through it.
To get the best performance from a Nikon 1 camera when shooting landscape images,owners should consider using a polarizing filter.
A polarizing filter changes the balance of light in a photograph and can help increase color saturation, reduce reflections, and improve shadow details.
The only difference in exposure is that the shutter speed dropped from1/250th with the first image to 1/160th with this image(using a polarizing filter blocks some light).
For a more dramatic effect use a polarizing filter which will improve the color of the sky, bring out the clouds and reduce the reflected glare off the water.
