Solar powered hot tub questions

[jiklrini]

I was wanting to get a house in part due to being able to do things like getting a dog, grill, hot tub, etc. I've heard it might be better to run the hottub constantly (in south USA) to save on power so that it won't need to strain from going cold to hot, and instead will just need minimal power uses to keep above a particular temperature. In this case, what kind of setup would I need in terms of whatever kind of solar power attachment to make it so that I could power the hot tub constantly, almost entirely from solar power? 220-240 volts probably for the potential hot tub. Generic size (nothing too big/ nothing overly small. Not clear on standard measurements. 7x10? 7x7?)
