Abstract:
A structure and method for utilizing solar energy for heating including a unitary, preferably modular, unit adapted to form an outer surface of a building, and having therein a reservoir suitable for storing fluid heat storage medium. The structure includes an outer glazing, an energy absorbing surface spaced inwardly from the glazing, and a divider forming an absorber channel adjacent the back side of the absorber. Preferably, the storage reservoir is separated from the back side of the absorber by an insulating divider defining the absorber channel. The structure is preferably self-supporting with a stressed storage reservoir and may be incorporated in a structure as a unitary module supporting at least its own weight and often forming a structural, stressed portion of the building. In operation, air may be selectively conducted through the absorber channel to accumulate heat energy from the back side of the absorber and, optionally, conduct the heat energy directly to the building volume to be heated, or over the storage reservoir to accumulate and store the collected energy. When radiant energy is not available, air may be flowed over the storage reservoir to withdraw heat energy to be utilized for heating purposes.
