The use of solar energy holds significant importance within the context of smart grid infrastructure, which is specifically designed to promote environmental preservation and long-term sustainability. Solar collectors are integral components of solar energy systems. Consistent maintenance of solar collectors will enhance energy efficiency and mitigate the use of energy resources. The aforementioned studies hold significance in the context of transitioning to a smart grid, particularly for developing nations. They provide light on how the existing energy production framework may facilitate the transformation of the conventional grid into a smart grid. This study focused specifically on the investigation of solar energy systems utilised as thermal energy sources. The energy efficiency of solar air collectors is diminished because of their low specific heat capacity and least expensive facilities to supply warm air for various applications. In addition, this study emphasizes investigating the enhancement of collector efficiency using double-layer glass coated collectors including arch-shaped obstacles. Three collectors were constructed with distinct features. The first collector, denoted as SC120, was designed without any obstacles and featured a double-layer cover as the witness. The second collector, referred to as SC121, incorporated obstacles with a width of 4 cm along with a double-layer cover. Lastly, the third collector, designated as SC122, included obstacles with a width of 7 cm arranged in a different configuration, also accompanied by a double-layer cover. A blower was installed in each collection to facilitate the forced air flow directed towards the absorbent material, ensuring that the volumetric flow rate remained consistent throughout all collectors. The trials were conducted over a span of five consecutive days, from 9 a.m. to 6 p.m., in an outdoor setting throughout the summer season. The findings indicated that the thermal efficiency of SC122 exhibited a 17% increase compared to SC121, and a 35.7% improvement relative to SC120. The presence of obstacles has a notable impact on thermal efficiency, with rough barriers leading to increased efficiency due to their ability to enhance the rate of heat absorption from the absorbent plate by the blown air.
