How are thermodynamic panels different to solar thermal panels?

A solar thermal system heats water already inside a panel and does not work when there is no sun. Because the refrigerant enters the combi thermodynamic panel at a lower temperature than water, this system is able to work even during the winter and at night. The thermodynamic panel is placed on the roof, ground mounted or wall and ensures the continuing capture of energy from sunlight on cloudy and rainy days.
