The availability of drinking water is essential for the survival of mankind. Adequate amount of water resources are available on our planet, but few of them can be used for the purpose of drinking. A number of water purification methods are developed by the researchers. However, Solar technology offers great potential in terms of supplying the world’s energy needs. The aim is to create an affordable unit, which can produce a clean drinking water from the solar energy. To achieve this goal, two types of solar water purifiers are developed and their performance is compared. One is Linear Fresnel Lens based water purifier. This lens heats the water up to boiling point. Steam is produced form the boiling process and that steam is condensed and collected in a reservoir. Other type of system is solar still which evaporate the water at its surface. Then surface droplets are collected into clean water reservoir. Water is purified by using these two systems. Performance of the both the systems is studied and compared. Adequate amount of solar radiations is necessary for the working of both the systems. So, total solar radiations received at the surface is also studied.
