Abstract: There is disclosed a solar energy operated system and method in which a quantity of liquid media is placed in solar collectors and heated to a preselected temperature therein. Upon reaching this temperature, the liquid is transferred to a first storage vessel. The liquid is replaced in the collectors from a separate second storage vessel. The hot liquid is drawn from the first vessel and circulated to a heat exchanger of a heat operated device, such as an absorption refrigeration device or a space heating device, and heat is exchanged thereby to operate such device. The liquid is returned from the heat exchanger of the device to the second storage vessel so as not to thermally contaminate the higher temperature liquid processed by the solar collectors. This is termed a batching method of operating the solar energy collectors in the system. The system maintains a supply of useful high quality thermal energy in the liquid media at a constant selected temperature to meet operating conditions of the heat operated device in which it is to be used. Also the system provides for auxiliary heating of the liquid to supplement solar energy when the latter is not readily available or insufficient to meet the demand of the load. Domestic hot water is obtained by circulation of water through heat exchange means in the second vessel. The functions of the system are maintained by an electronic programmable controller to carry out the transfer of liquid in the system according to selected data and conditions.
