Solar Water Heating Pump Controller - This controller detects the temperature of the solar panel as well as that of the tank which stores the heated water. Whenever the solar panel is hotter than the stored water, the pump should run to send hot water from the panel into the hot water tank. However, when the stored water is hotter than the solar panel, the pump (pictured below) should be off since the stored water would otherwise be cooled by the panel.
