Abstract
An improved solar energy control system and method are disclosed that enables efficient utiliziation of heat produced from solar energy in heating air and/or water. The system and method sense the availability of heat along with the need for such heat at monitored areas and, responsive thereto, selectively directs the heat to the monitored areas as necessary to cause the temperature in each area to be increased to predetermined levels. To most efficiently utilize heat derived from a solar collector, the heat initially made available from the collector is directed to the water within a temperature monitored water heater when the water is sensed to be at a temperature lower than the air in a temperature monitored room. The heat available from the collector is directed to the air in the temperature monitored room when sufficient heat is sensed to be available at the collector to heat the room and such heat application is continued until the temperature of the monitored room reaches a preselected temperature, after which the heat from the collector is directed to the water in the water heater until the water temperature is increased to a preselected temperature, and then the heat from …
