Solar water heater installer we recommend

[roberb7]

I had solar hot water installed by the same guy at the beginning of December.
With two exceptions, the water has been good and hot every morning. There were two days when the previous day was entirely overcast. The water wasn't warm, but not cold enough to justify re-activating the butane water heater. If there was two overcast days in a row, I would have to go the "re-activate" route.
The solar hot water heater has its own tank. The setup includes a couple of valves, so if you close one, and open the other (and light the pilot light), you're back to butane.
I'm very happy with it. One fringe benefit is, up until this installation, I was doing my laundry in cold water, the same as everyone else does. Now that I have hot water at no additional cost, I can do laundry in warm water.
