Back to the original question about solar, generally if your application is heating water, you would go a solar-thermal route where the sun is directly heating the water, rather than using a solar panel and then trying to run a heater off the resulting electricity. If you think of how hot the water can get in a hose on a sunny day, that's the effect they mimic.

The solutions are a little different depending upon whether your goal is to prevent water from freezing or whether you are trying to create genuinely hot water. There are DIY plans and ready-made solutions for both around.

That said, as others suggested, I think you'd find that running electricity is going to cost you a similar amount, and electricity has the benefit of being more flexible and useful for more things.

The other thing that I have seen is a solar panel running a bubbler. The movement of the water keeps ice from forming directly above the air outlet, and it takes significantly less power than heating a tub of water.
