Solar energy system performance evaluation, Hogate's Restaurant, Washington, DC, June-August, 1978
This system is designed to provide hot water on demand for the kitchen facilities located at Hogate's Restaurant. Presented are results of an evaluation of measured system performance and a comparison of measured climatic data with long term average conditions. Performance evaluations of each major subsystem are also presented. A brief system description, review of actual system performance during the report period, analysis of performance based on evaluation of climatic, load and operational conditions, and an overall discussion of the results of analysis are included. The solar energy system operated satisfactorily for the reporting period. The average incident solar energ was 260 million Btu per month of which 90 million Btu were collected resulting in a collector array efficiency of 34 Btu were collected resulting in a collector array efficiency of 34%. Solar energy collection and utilization are approximately in phase at Hogate's Restaurant. This, coupled with the high rate of water consumption of 7000 gallons per day, results in a 97% storage tank efficiency. The average monthly thermal load is 130 million Btu of which 63% is satisfied by the solar energy system.
