Design and Fabrication of a Solar Evaporator with Light Focusing Mirrors

Today, solar evaporators have been attracted researchers attentions due to their low cost, application facility and environmental considerations. They can be an appropriate alternative for thermal heaters, which use the fossil fuels. In this study, firstly a review on solar energy absorption systems has been presented and then manufacture and design procedure for a homemade solar evaporator, which can be used in buildings. This produced evaporator consumes 100 W electric current and 800 W.hr during a day and it can provide 48 liters distilled water in a day. Total cost has been calculated in three cases: 1-80% evaporation of input water with solar energy absorption efficiency of 100% or 50%, 2-100% evaporation of input water with solar energy absorption efficiency of 50%, 3-100% evaporation of input water with solar energy absorption efficiency of 50% with energy recovery in two cases of 50% and 75%.
