The results of a systems analysis and economic study of a photochemical solar energy system are presented and compared with a conventional hot-water solar energy system. Conversion efficiency, energy storage capacity, and life-cycle costs are the primary bases of comparison. The paper indicates the requirements to make a photochemical solar energy system technically and economically feasible and identifies potential advantages of the photochemical solar energy system--i.e. lower cost and lighter weight collector, cloudy-day effectiveness, smaller storage tank, storage at room temperature and uniform energy levels in the stored fluid, both winter and summer. Two possible problem areas have been identified for a photochemical system: anticipated higher initial cost of the working fluid, and possible deterioration of the energy storage capacity with time.
