I have heard too many horror stories about direct solar hot water. Sure it might work well, and can save a lot of money, but if it breaks it can get VERY expensive. I am looking at electic hot water that only heats with excess solar power though, not mains. Saves sending power to the grid and getting paid very little for it.
