A family of three is considering to install solar water heater system. Each person needs 50 liters of water per day. They require a hot water with temperature of 50 °C from using tap water as a source with a typical temperature of 20 °C. Calculate the required heat energy to satisfy the family demand in a year, and calculate the required area of flat plate collector (its efficiency 40% with energy gain 540 kWh.m-2/ year) and evacuated tube collector (its efficiency 60% with energy gain 800 kWh.m-2/ year) that needs to be installed. Describe your answer.
