Abstract The design of the solar collector included rectangular ducts made of black anodized aluminum, which improves heat transfer to the air due to the good thermal conductivity of aluminum and the extended heat transfer area. Experimental results show that under good irradiance conditions (> 1000 W/m²), temperature differences between the inlet and outlet of the collector of 27.4-43.3 °C can be obtained with a working flow rate of 0.029-0.060 kg/s and a thermal efficiency that in some cases exceeds 70%. The efficiency of the collector depends on the air flow rate, which in this design is controlled by a fan equipped with an electronic control device. The proposed numerical model, based on simulation in Python, shows strong consistency with experimental measurements. This model can be used to optimize the components of the solar collector and to analyze the air heating process, allowing parameters such as air flow rate and climatic conditions to be varied, thus predicting the behavior of the collector in other geographical regions.
