In this context, four different solar desalination systems including a conventional solar still, solar still with thermal energy storage unit, solar still with CuO nano-embedded latent heat storage unit and solar still with CuO nano-enhanced absorber coating and thermal energy storage unit have been developed, fabricated and empirically analyzed. Experimental results showed that combined employing nanoparticles upgraded accumulated productivity as 26.77% in comparison to conventional solar still. Also, energy and exergy efficiency values were enhanced from 15.96% to 19.90% and from 1.25% and 2.01%, respectively with the use of combined modification. © 2022EnglishDesalinationDistillationHeat storageLatent heatNanoparticlesPaintSolar absorbersSolar heatingAbsorber coatingsBlack paintCombined utilization of copper oxide nanoparticleCopper oxide nanoparticlesEnergy storage unitLatent heat storage unitsModelingSingle slopesSolar stillsThermal energy storagecopper compoundenergy storageexperimental studylatent heat fluxnanoparticleThermal energyArticle10.1016/j.solener.2022.01.039
