Frank,

thanks for your reply.

In sizing the system I realize that it is important to (ideally) match the
storage volume to both the collector area and the demand. A thirty gallon
tank is much easier to find around here, and given that the water heater
we've been using for the past fifteen years is a 20 gallon model (from the
forties) I'd think at least with respect to the demand part of the equation
the thirty gallon tank would be adequate or just about perfect. I would
also prefer to have
- a thermosiphon system, and
- drain it in the Fall as your neighbor does.

Cheap, simple, and with manual interventions is generally my preferred
approach to these kinds of systems.
