In this study, the performance of single slope solar still combined with enhanced condenser and integrated

with
 parabolic trough solar collector (PTC), is assessed based on productivity, energy, exergy,
exergoeconomic,  and enviroeconomic methodologies. Experiments are conducted using various saline water media  inside a  basin exposed to the hot weather conditions of Sohag city in Upper Egypt. Several solar  still configurations are tested: conventional solar still (CSS), modified solar still (MSS) using aluminum heat sink  as enhanced condenser (HSC), modified solar still incorporated with PTC (MSS + PTC), modified  solar still comprising sand as a porous media inside the basin (MSS + SD), and modified solar
still comprising  sand inside  the basin and incorporated with PTC (MSS + SD + PTC). The experimental findings  revealed that the MSS + SD + PTC achieved the highest freshwater productivity of 4.65 L/m in winter and  9.75 L/m2 in summer, leading to an improvement of around 113 % in winter and 146 % in summer  compared with the CSS system. The highest increase in energy and exergy output per year is obtained
 in the case of MSS + SD + PTC at 139 % and 245 %, respectively. Incorporation of PTC into the MSS  system for all studied water media is found promising in terms of energy payback time, cost, and freshwater yield  compared with MSS without PTC. The exergoeconomic and environmental parameters of  the active systems are found more effective compared with those of the passive systems.
