Abstract

In this work, a hybrid desalination system uses solar thermal-electric clean energy to maximize production and consistency through optimum temperature management to deliver clean water for good health. It is an effort in the direction of aligning with few of UN's sustainable developmental goals. BIPV system-powered thermoelectric modules boost evaporation and condensation rates in a unique bio-inspired butterfly roof design-based twin wedge solar still (TWSS). A microcontroller-based temperature control unit (TCU) regulates and maintains the hybrid system to provide practically constant higher yields. To understand system performance, 3days of testing has been carried out. Average yield, energy efficiency, exergy efficiency, cost per liter of freshwater, and payback period of hybrid TWSS (hTWSS) and passive TWSS over 15years are 8.64l/m2/day, 61.93, 9.05, and 0.116 $/l in 44months, and 1.3l/m2/day, 23.06, 1.26, 0.068 $/l in 20months. The hTWSS mitigated 5.1 tons and TWSS 59.6 tons of CO2. This hybrid technology utilizes clean energy to deliver clean water and electricity in green energy buildings with a small footprint. As a futuristic work, AI and machine learning are suggested to be used to enhance and commercialize this solar still desalination method.
