Will using a solar powered fence save on my electric bill?

I have a horse and we need to put an electrified fence up round part of our yard. I don't really want to run a power cable all the way from my house out to the horse area so I thought a solar powered fence would be a good alternative.

If I could get a solar system that has enough power to run some sort of water heater for part of the year so I can keep the ice away from their drinking water that would be good to know about as well.

I want some sort of solar power kit that I can just buy, haul home and install myself without having to pay a company to come out and do anything at all.
