LIFE CYCLE COST ANALYSIS OF AN ACTIVE SOLAR DISTILLER USING NANOFLUID

The availability of clean water is a prerequisite for economic and social progress. The purpose of this research is to improve the efficiency of solar stills using flat-plate collectors for desalination of water, with an eye on their usage in low-volume, far-flung settings. In this study, we use the principle of life cycle cost analysis to determine the price of a kilogram of distilled water. Return on investment (ROI) calculations have been made for both production costs and market prices for distributed distilled water. Based on experimental results, using nanoparticles of either 10 or 50 nm in size significantly increased solar still production compared to using only the base fluid. It was also discovered that as nanoparticle size increased, the cost of distilled water decreased and the payback time shortened. Conclusion: As nanoparticle size increases, basin type solar stills' thermo-economic performance degrades
