Abstract In this paper, the modeling of honeycomb double exposure solar still has been analyzed include four elements, such as the glass cover, honeycomb structure, water mass, and bottom absorber. The energy balance equation has been written for the still parameters. The computer program has been written for the analytical solutions of water, glass, and bottom absorber temperature. To validate the analytical results, experimental observations for one of the typical days in February 2012 have been taken. The correlation coefficients have been found and their r2 values for water and bottom absorber are presented. Keywords Honeycomb solar still • Desalination • Correlation
1 Introduction Supply of drinking water is a major problem in under developed as well as in some developing countries. Distillation method is a best solution for this problem. Distillation of brackish or saline water, wherever it is available, is a good method to obtain fresh water solar distillation uses the heat of the sun directly in a simple piece of equipment to purify water. The equipment commonly called a solar still John Ward [1]. The analytical and experimental study of a plastic solar water purifier has been done. The experimental study had shown that the sea water input with 35,000 ppm of totally dissolved solids is converted into portable with a totally dissolved solid of 1.2 ppm without the taste, smell, and color of plastic with distillate yield for up to 1,000 W/m2 insolation and 35 °C ambient temperature Delyannis [2]. The analytical study of a historic background of desalination and renewable energies has been done. The historical path revealed the most important ideas and today on destination of sea and brackish water as well as renewable energy utilization with special K. Shanmugasundaram (*) · B.

reference to use of solar energy for desalination Mathioulakis and Belessiotis [3]. The simple solar still has been designed and its incorporation in a multi-source and multiuse environment has been analyzed. It had shown that the efficiency and productivity increases in multi-source environment Singh and Tiwari [4]. The comparative study of monthly and annual performance of passive and active solar has been carried out and for different Indian climatic conditions. It has been concluded that the annual yield depends on water depth, inclination of glass cover for both active and passive solar still. The annual yield of active solar still for a given water depth increased linearly with the collector area. Rajesh Tripathi and Tiwari [5], the condensing covers with characteristic dimension of 0.14 and 0.07 cm made of aluminum and coppe
