Evaluation of the Measured Energy Performance of Four Solar Systems.
Abstract
This report describes the measured energy performance of four solar systems installed in military construction. Based on measured performance for a period of about 1 year, none of the solar systems provided the energy savings expected from the design calculations. When the fuel cost savings produced by the solar components of the systems were compared with the added solar costs, the solar systems had simple payback periods of more than 25 years. The field problems for the solar systems revealed by the study are discussed and related to system performance. The performance of all four systems suffered from control failures and excessive operation and maintenance (O/M) requirements. It was concluded that reliable, efficient designs must be simple and based on proven technologies. Recommendations for improving future solar designs are presented. Originator-supplied keywords include: solar heating, solar air conditioning, and military facilities.
