In arid regions facing challenges of limited access to potable water and electricity, solar desalination stands out as a promising solution for producing clean water from brackish sources. This research intends to examine and enhance an innovative and sustainable solar desalination system. A computational study is conducted on a pyramid solar still (PSS) combined with a phase‐change material incorporated with nanoparticles, with a variety of absorber fins. The study investigates three configurations: a traditional pyramid–shaped solar still, one with square absorber fins, and another with circular fins. Paraffin wax mixed with Al2O3 nanoparticles is used beneath the absorber fins. Conservation equations are solved using COMSOL Multiphysics. Simulation outcomes demonstrate that the incorporation of finned absorbers, coupled with elevated water temperatures, significantly enhances the yield of the improved PSS compared with its conventional counterpart. The square‐finned absorber PSS exhibits a substantial increase in total accumulated productivity over the conventional design. Moreover, the PSS with square‐finned absorbers demonstrates an impressive average peak daily thermal efficiency improvement of 49.19% compared with a conventional solar still. This study highlights the effectiveness of the modified PSS as a superior option for household water generation.

This study aims to upgrade the thermal performance of a passive solar system, specifically a Trombe wall (TW), by incorporating a metallic absorbent made of copper chips into its absorbent surfaces. The paper compares the thermal performance of a classic TW with that of a copper chip-enhanced TW. An experimental test was set up for classic and copper chip–TW systems, and a full-day experiment was conducted in January 2018 to investigate the thermal performance under the same operating conditions. The experimental data were used to verify a mathematical model based on energy balance. The theoretical study agreed well with the experimental data, with a maximum error of 11% in the absorbent surface temperature valuation. The results revealed that adding copper chips to the TW system boosts its performance by increasing heat gains and improving thermal efficiency. It improves thermal efficiency and enhances the mean room temperature by 12.44% and 14.1%, respectively.
