The Statement of Work of the contract for which this report has been prepared was changed significantly at the end of the first year by DOE. The original contract was basically to establish a residential sized solar cooling system test facility for: steady and dynamic system performance testing, in situ component testing, simultaneous model and experiment validation, optimization of control strategies to minimize parasitic thermal and electrical loses, and to determine the optimum split between electrical and thermal conversion from the collector array. Particular emphasis was placed on concentrator PV/T collectors and absorption cooling. In July 1980 the Statement of Work was changed to combine both analytical and experimental studies aimed at assessing the role of concentrator PV/T collectors. Under the new scope of work, this project has attempted to determine when PV/T collectors have an advantage over side-by-side PV arrays and thermal collectors. This report represents a summary of the work completed after the Statement of Work was changed. During the course of this work a new formulation of the utilizability concept of Whillier, Liu and Jordan and Klein has been developed. This new approach is useful in predicting the monthly thermal gains of a thermal collector operating with a fixed inlet fluid temperature. This formulation relies on knowledge of only very minimum of site dependent data and is described in the report.
