The Stevens Home in California is a single family residence whose active solar energy system is designed to supply 70% of the hot water load. The system is equipped with 68 square feet of flat plate collectors, a 120-gallon solar preheat water tank, and a 40-gallon propane water heater. The solar fraction predicted by computer simulation and measured were the same, 44%. The system solar savings ratio, conventional fuel savings, and solar system coefficient of performance for the period covered are given. Monthly performance data are tabulated for the overall system and for the collector, storage, and domestic hot water subsystems. System operation is illustrated for a typical day by graphs of the temperatures at collector array, inlet and outlet, and at the preheat tank, and of water consumption. The typical operating sequence and solar energy use and heat losses are also graphed. (LEW)
