The scarcity of freshwater especially in remote areas led the researcher to find alternative techniques to produce suitable water for human everyday life; one technique is using solar energy. Water desalination systems depend on traditional energy resulting from the use of fossil fuels, which results in their use of many environmental and health hazards. Solar energy is one of the important and promising solutions to the energy crisis, as well as the solutions developed to solve the crisis of harmful waste that affects humans and the environment. There are many uses for which solar energy can be used such as using photovoltaic cells as well as using solar energy condensers to benefit from the thermal energy associated with sunlight. This paper will review previous studies which concern the desalination processes of seawater and brackish water solar energy parabolic dish concentrators. Compound parabolic collectors (CPCs) have been shown to be cost-effective and beneficial in a temperature range below 100 °C, as well as, in the temperatures range of (100 °C-250 °C) in solar desalination systems, and so there has been a rising trend in their use in recent years
