I have never heard of "thermodynamic panels". And as far as I know the only way to get hot water while the panels are not in the sun is to store heated water in a tank such as a conventional water heater or to heat a phase changing medium that stores the heat inside an insulated area to be used to heat water directly as needed when the sun is not there.
