Abstract
The current research intends to create an efficient absorber plate aimed at enhancing energy capture through the use of an expanded absorber surface. To achieve this, an array of rectangular pipes is used to expand the absorber area. The investigation is specifically carried out on an SAH measuring 120 cm in length, 85 cm in width, and 12 cm in height, which is oriented southward and inclined at a 30° angle. The results indicate that the improved SAH can exhibit a significant enhancement in performance, achieving an overall efficiency of 38.4%. Additionally, the modified SAH has the potential to increase air temperature by up to 28.9 °C at the specified tilt angle of 30°. Furthermore, the findings suggest that increasing the absorber area is an effective strategy to enhance the performance of the SAH. Such advancements in solar thermal collector efficiency are pivotal for accelerating the adoption of renewable energy in the industrial sector, contributing directly to the decarbonization of process heat and advancing the objectives of SDG 7 (Affordable and Clean Energy) and SDG 9 (Industry, Innovation, and Infrastructure).
