The next explosion in solar power research was in 1997 as consequence to
Kyoto Protocol. This protocol outlined the effect of greenhouse emission which
endangers our Earth. As the result, research in solar power field started to take
its path again. This work is a part of the UTeM project to build the first CST
model in South East Asia and was aimed to develop an azimuth-elevationmode-based
template using MATLAB programming for the calculation of the
heliostat position with respect to the heat absorber mounted at the top of the
CST. This template will serve as the calculation platform to control the
movement of the heliostat using a two-axis motion system so that the sun light
will be redirected perfectly to the absorber all day long. Since the heliostat
normal vector depends on sun position vector, both vectors were calculated
by the program and were set as the output of the program. The input from
the user will be the Cartesian coordinate of the heliostat and absorber by
taking the absorber tower frontal surface and its base as the origin and also
the date. The result will be in vector form and will change automatically
according to the Sun movement. These values will be programmed in the
micro controller which will control the motion system of the heliostat, which will
be done by the Control Department of UTeM. The program´s functionality was
proved via several verifications and its accuracy which is 0.0005 as stated
and verified via comparison with analytical calculations. From the
verifications, it can be seen that difference of the numerical and analytical
results varied from 0.0000 to 0.0005 which validates the statement of minimum
accuracy of the numerical calculated results is 5/10,000.
