Abstract Solar stills are a popular choice for distilling water and removing harmful contaminants like arsenic and other minerals in some rural parts of Argentina. The processes involved in solar still are environment friendly as they are driven only by solar energy and do not require any external energy sources (such as electricity or energy from combustible products). The objective of the current study is to couple such a solar still with a photovoltaic array in order to generate both potable water and electricity simultaneously. A model for such a system is developed and used to simulate the conditions of boath constant and variable irradiation. It is found that the water which evaporates in the solar still extracts the heat from the photovoltaic module consequently decreasing its temperature. The photovoltaic array coupled with the cogeneration system operates at temperatures which are lower than a stand-alone cell, thereby increasing the efficiency of the cell. With water and electricity as the byproducts of the system, the efficiency of the entire system is increased. Details pertaining to thermal analysis of the system are discussed.
