Abstract
In this paper a mathematical formula was driven to estimate the tilt angle of
surface from horizontal Σ and the surface azimuth angle Ψ for a flat plate solar
collector which gives maximum total incident solar radiation on a flat plate solar
collector designed for heating water. According to the formulas of estimating Σ and Ψ
which driven in this study a C++ program had been built and used to simulate the
performance of a sun trucking solar collector, so the collector orientation varies with
day time to give maximum incident solar radiation at each hour (in this case one hour
time interval used) by estimating the surface azimuth angle and the tilt angle of
surface from horizontal at the desired hour (time),and compare the results with the
normal case of using stationary solar collector (oriented to the south with tilt angle
equal to latitude). All calculations done for the city of Baghdad in January .Results
show that the incident solar radiation and storage temperature in the case of sun
trucking collector system is greater than it's in the case of stationary collector (normal
case) which gives system more stability.
