This paper contains the results of an evaluation of long-term performance of six solar energy systems that produce industrial process heat (IPH). The solar energy systems were constructed under a program funded by the US Department of Energy. Periods of operation covered in this evaluation ranged from 8 months to 1 year during the period October 1982 to September 1983. During this time long-term energy production was measured, clear-day performance was recorded and reported, and operation and maintenance data were collected. The evaluation contains a comparison of measured energy production with predictions from computer models, computations of system efficiencies, detailed analyses of thermal losses, and costs of operation and maintenance. With the exception of one experiment, energy production was less than predicted primarily because of excessive thermal loss in the systems, tracking inaccuracies, system down time, and inability to precisely model the systems and their operation.
