Enviroeconomic analysis of a hybrid active solar desalination system using nanoparticles

The water crisis is the focus of this work, and there is a dire need to develop eco-friendly and self-sustainable water supply units. This study performed an economic and enviroeconomic analysis of N identical photovoltaic thermal compound parabolic concentrator collectors with double-slope solar desalination units with a heat exchanger using water-based aluminium oxide (Al₂O₃) nanoparticles. In this analytical study, a program was fed into the Matlab environment, and the analysis was monitored on an annual basis in New Delhi, India. The Indian Metrological Department in Pune, India, provided the input data necessary for the mathematical procedure. From the year-round solar energy, yield and energy production were calculated. The economic, environmental and energy-related performance of the system was assessed, and it was compared with those of previous systems. Additionally, based on annual and lifespans of 15, 20 and 30 years, it was discovered that there is an 8.5% greater yield, 7.31% greater annual energy, 3.9 and 2.85% less carbon dioxide (CO₂) mitigation/t energy and 5.17% greater annual productivity, carbon dioxide credit respectively. Based on energy, environmental and economic factors, it was determined that the suggested system was superior to alternative systems.
