•An objective Solar Desalination Applicability rank scoring system (0 ≤ R ≤ 1) is devised.•Scores consider water scarcity & stress, solar insolation & saline water availability.•30 nations have “High Applicability” and 28 have “Moderate Applicability”.•Results could help inform national and international water management policies.•Results could help equipment suppliers identify and quantify emerging markets.
