Analysis of field-test data from domestic solar-water heaters in the southern United States, period through May 1982
Abstract
Monitored performance data gathered from 103 solar water heaters are presented. All except 25 of the water heaters are located in Florida. The locations and system types of the solar water heaters are tabulated. The annual energy saved, solar savings fraction, return on investment, and gallons per purchased energy are given for the systems. Analysis of the thermal performance data is discussed. The solar water heater sites are ranked according to various thermal performance values, and thermal performance data are plotted. Presented with the plots are the mean and standard error of the particular groupings of monitored data. Operational statuses causing performance interruptions are tabulated.
