The solar desalination system is a hybrid system combining a Fresnel solar concentrator with a desalination chamber, and which uses membrane distillation for desalination of seawater. The desalination chamber includes a lower wall having a central absorber base, at least one sidewall, and an upper wall. A pair of hydrophobic membranes are mounted within the desalination chamber such that a central chamber is defined therebetween above the absorber base. The desalination chamber is suspended above a linear Fresnel reflector array so that the absorber base is positioned at a focal line thereof. Seawater is fed into the central chamber, where it is heated to produce water vapor, which passes through the pair of hydrophobic membranes into a pair of condensate retrieval chambers. The water vapor cools in the pair of condensate retrieval chambers, and may then be removed in the form of pure water.
