Experimental investigation on effect of modified solar collector in solar water heating system

The conventional SWH is always use the flat plate collector along with straight tubes for heating of water using solar rays which is having efficiency of low. This efficiency is directly linked to dimension of the flat plate collector which is critical to both cost of the equipment and also high carpet area requirement in buildings for installment. To overcome this dimensional criticality we propose to change the flat plate collectors into bend type tubes. In general increasing the surface area of the collector will increase the heat transfer capability of the solar collector and possibly its efficiency. Conventional solar water heaters have longitudinal flat surface collector tubes for reaping the benefits of solar heating. Water temperature increases 10-12°C than existing water heater and also payback period less than the existing one.
