Abstract: A comparison of thermal performance of the chemically and thermally oxidized 188 Cr Ni austenitic stainless steel (SS) solar absorber plates (light blue in colour) under bright sunshine conditions in Benin City, Nigeria, shows that the thermally oxidized austenitic stainless steel AISI 321 performs better than the chemically oxidized (SS) absorbing surface. The highest temperature recorded on a clear bright day, for a singly glazed, thermally oxidized (SS) absorber plate was 108 °C as against 102 °C for the chemically oxidized (SS) absorber plate under the identical conditions of plate masses and dimensions.
