However, one of the criteria to improve the efficiency of the collector is to increase the absorbed radiation by the collector [2-4], which emphasizes the importance of proper orientation of the collector. For value for money, the collector should be oriented properly so as to receive maximum solar radiation.
Based on the incident angles of the direct solar radiation, Skeiker (2009) Presented a mathematical model to compute the optimum tilt angle and orientation (surface azimuth angle) of solar collector Syrian zones and recommend that by changing the tilt angle 12 times in a year and found the solar radiation approximately is the maximum data .
As studied by different authors [2-5], general rules of thumb can be stated for the installation of solar flat plate collectors. For maximum annual energy availability, the slope of the collector should be equal to the angle of latitude for low latitude countries ( < 40°), increasing to latitude plus 10° for higher latitude countries ( >40°).
Therefore, the period, which starts when the heat collection exceeds 0, is defined as the available operating time of collector operation. Furthermore, the solar energy, which is irradiated on the collector surface, is the effective radiation energy within the effective operation time of the collector.
