In Gaziantep, many people use the energy of the Sun for heating their domestic water used for having shower in bathroom, for washing-machines, for kitchen stuffs, and etc. An ordinary solar collector panel is generally constructed on the roof of a house and the panels are declined approximately 60° with the horizontal line. Commonly, the total surface area of two glass panels is approximately 4.0 m² (2 panels: 1980mm x 1000mm for each) and they receive the energy from the Sun to heat the water. Although there is an inclination by 60°, it is reported that the twenty percent of the total incoming energy is reflected back to the atmosphere by well-insulated panel's glass surface. The remaining energy is used to heat the domestic water from 20°C to 50°C, and it is stored in storage tanks in a sunny day. The cold water enters from the bottom side of panel and exits from the top. It is assumed that the water passing through the solar collector has a negligible pressure drop. If the volume…
