Solar absorptance data on Pyromark painted receiver panels at the 10 MWe Solar Thermal Central Receiver Pilot Plant located near Barstow, California are reported. Measurements were made in 1982, 1983, and 1984. Selected measurements were made in 1985 after one receiver panel was repainted with Pyromark. The results show a linear decrease in the solar absorptance with time from an original average value of 0.92 to 0.88 after 663 days. The decrease in solar absorptance correlated with the higher incident solar flux levels on the receiver panels and not with the operating temperature of the panels. Repainting of one receiver panel successfully increased the solar absorptance to a value above 0.96.
