India is an emerging and developing country. Till now, there are many villages of rural areas have no access to the potable water. There are many ways available for water desalination. Solar energy is the renewable source of energy that can be obtained directly from the sun. It is widely available all over the world so, it has been selected for our work. Solar desalination is the future scope for water distillation. The aim of this work is to determine the efficient collecting surface for the conventional solar still. The conventional solar still was designed and fabricated successfully. The performance of the solar still is monitored by changing the shape and structure of the collecting surfaces. The finned and corrugated surfaces were selected for this analysis and they were also designed and fabricated as per the requirements.
