Derivation mathematical formulas for tilt angles of a flat plate sun trucking collector with a simulation In C++ language

الملخص EN

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.
