The requirement of hot water varies from person to person depending upon his water uses pattern. However, it is estimated that the average hot water requirement per person per day in an average household in India is around 65 liters at 40º C. For calculations of hot water requirement and sizing of solar water heater system, a software was designed in India to help any resident to calculate their Solar Water Heating System needs.
The calculator, at present, is designed to calculate the approximate size of the collector and the storage tank of a solar system for individual residential applications. The final aim of the calculator is to facilitate the simulated software for all kinds of solar water heating applications.
