Description: The analysis and comparison of the output of the solar energy section of DOE-2 called Component Based Simulator (CBS) and TRNSYS are discussed. The adequacy and sensitivity of CBS when various active solar energy collectors and systems were interfaced with a standard space heating system were investigated. The analysis included both single- and double-glazed collectors with selectively and nonselectively coated absorbing surfaces located in four different environments. The results of the study show the agreement between the two programs to be remarkably similar. Graphs are presented to illustrate the minor differences in annual average collector efficiency and annual average part solar as well as the thermal load and insolation levels. In addition, difficulties encountered by the researchers when performing this study and when attempting to model the collector systems with each program's components are discussed and recommendations offered to facilitate the solar simulation process for future CBS users.
