@MarkP - i have a standard style solar water heating system. Two, 2'x8' panels on the roof and a 120 gallon tank under the house which has the big elements for heating, but because of how little hot water the two of use, I don't even have the breaker turned on for it. I simply let the sun do all of our water heating. If I recall, the tank gets up to around 135 degrees, so after blending in cold, we can get about 4 days of hot water with even no sun. I can always manually flip the breaker if for some reason we need mote hot water.
