In this study, an air solar collector (SAC) was compared in three different ways (flat plate, serial connection, and parallel connection) using aluminum Coke cans according to the conditions of the region. Experiments were conducted at an air speed of 3 m/s to 6.5 m/s. Data were compared with each other according to two different air flow rates with three different flow forms. As a result of the experiments, the highest temperature difference in the measurements made at 3 m/s air speed was 68°C in the Parallel Collector and 56°C of the serial collector at 6.5 m/s air speed was observed. According to the results, when the system was operated at 3 m/s, it was seen that parallel collector provided good results, and when it was operated at 6,5 m/s, it was seen that serial collector yielded good results. At the end of this study, it is possible to conclude that choosing the proper air flow type can be applicable in terms of energy efficiency in order to increase the efficiency of the collector.
