Abstract
This report describes work performed in FY 1984 at the Solar Energy Research Institute as part of the continuing effort to lower the delivered energy cost of solar domestic hot water and space heating systems. In this work, a cost and performance comparison of drainback and integral collector storage (ICS) systems was conducted. Cost data for installed system costs were developed for both systems. Performance for the systems was generated using either accepted design tools (FCHART for drainback systems) or new methodologies (for the ICS systems). The cost and performance data were used to calculate discounted payback as a means for comparing the two systems and for assessing their market potential. The results of this economic analysis show that ICS systems have lower discounted paybacks than commercially available drainback systems. Low-cost drainback systems using new, low-cost components have about the same discounted payback as ICS systems.
