Abstract
Abstract ABSTRACT OF THE DISCLOSURE A system is disclosed for controlling the exchange of heat between a heat exchange medium and a solar panel which has an inlet and an outlet and a circulation control associated therewith for controlling the circulation of the heat exchange medium through the solar panel from its inlet to its outlet, the system improving the. amount of heat exchange between the heat exchange medium and the solar panel by sensing the temperature difference of the heat exchange medium at the outlet and the inlet of the solar panel and de-energizing the circulation control when the temperature of the heat exchange medium at the outlet approaches or becomes equal to the temperature of the heat exchange medium at the inlet.
