Performance analyzing of an Inverted Absorber Basin Solar Still Equipped with Photovoltaic Cells

Present study is a basin solar still system that a curvy inverted reflector is connected to the basin’s below and some photovoltaic cells are inserted on glass condenser. So, the system produces fresh water and electricity, simultaneously. By writing energy balance for different components of the system such as expressions for PV cells temperature, glass condenser temperature, water temperature, and absorber temperature are obtained. Also, the system thermal and electrical efficiency are introduced. Present study simulation results are in consistent with experimental data of the previous studies. Parametric study results show that increased water depth reduces fresh water productivity and it’s effect on electricity production is negligible. Increasing PV cells reduces fresh water productivity and raises electricity production. Increased wind velocity increases fresh water productivity and electricity production. Increase in Basin area increases fresh water productivity and electricity production. Also, increased PV cells increases electrical efficiency and reduces thermal efficiency, so overall, it decreases system overall efficiency. Water depth effect on electrical efficiency is negligible but, it decreases thermal efficiency and the overall efficiency of the system.
