| Abstract | Drying is a key post-harvest process for preserving agricultural and herbal products. However, under humid tropical conditions, drying remains energy-intensive and limited in performance. This study presents the development and performance evaluation of a photovoltaic–thermal (PVT) solar dryer integrated with porous absorbers to enhance heat and mass transfer. The system consists of a 150 W PVT panel and a solar air collector equipped with porous steel mesh absorbers with porosities of 0.98 and 0.96, together with a non-porous reference configuration. Drying experiments were conducted in Thailand under tropical conditions at an air velocity of 0.1 m/s using kaffir lime leaves. The results show that porous integration increases the effective heat transfer area and thermal energy retention, resulting in a drying rate increase of up to 50% and a reduction in specific energy consumption (SEC) of up to 33.3% compared with the non-porous system. The configuration with a porosity of 0.96 provided the best overall performance. Overall, integrating porous materials into a PVT solar dryer significantly improves drying performance and energy efficiency. |
