The coil is connected to the solar heater. You've got the configuration backwards.
What you described above is exactly how mine is setup.
My collectors drop hot water down thru a coil inside my insulated preheat tank then back up to the collectors.

The water surrounding the coil is my domestic hot water which is run to my tankless hot water heater. It is preheated to about 64 to 80 degrees in the winter and much hotter in the summer.
