Customer ServiceHowever, 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.
The solar collector has to take the optimal position that will guarantee the highest generation of heat. Optimal positioning must be based on rigorous calculations and not on the basis of experience. Such calculations lead to the improvement of the operation of solar energy systems. This paper gives

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°).
For maximum annual energy, the collectors should be tilted towards the equator, i. e. towads the south in the northern hemisphere and north in the southern hemisphere. At Iqbal , when the slope is optimum variation of surface azimuth angle does not have significant effect on the received solar energy.
