I forgot to mention that I went up on the roof and installed a vacum break type valve at the highest point where hot water leaves collectors on route back to drain back tank. This valve allows a pinch of air into piping as water flows by but will not allow water to leak out. Just perfect for the application.

Do you think a single collector would suffice for the average home hot water supplement?
Now I am considering point of use tankless electric heaters, one at each bathroom and at the kitchen, and put two of those zones on a circ pump with timer and put the solar trank system near the other.
I'd go with your drainback system and a modest 30~40 gallon storage.
