Energy, exergy, economic, environmental analysis for solar still using partially coated condensing cover with thermoelectric cover cooling

The declining freshwater resources can be overcome using thermal desalination methods such as solar still. However, the productivity of a still is highly dependent on environment and design. In this study, an improvement passive with partially coated condensation cover thermoelectric cooling system was made. effect varying power (12 W 36 W) investigated compared reference under tropical weather conditions Malaysia. performance analysed in detail based yield, energy, exergy, environmental economic aspects. results showed that production could increased by up to 126% capacity. energy efficiency improved 44%, but exergy decreased 25% matrices show minimum payback time maximum factor for glass are 6.55 years 0.15, respectively. amount carbon dioxide mitigated modified 2.97 tonnes CO2 lifetime. lowest cost per litre found $0.036 W. highest exergo-economic enviro-economic values were 4.64 kWh/$ $83.21,
