Abstract
Solar irradiation is a green and sustainable renewable energy source which is largely harnessed through
photovoltaic and thermal cell surfaces. It is one of the fastest growing clean power technologies with
high-global growth figures, due to its simplicity, affordability and abundant availability. Solar power systems
is one of the fastest growing interventions augmenting fossil power and its application is now
expanding beyond domestic utilization to commercial and industrial dependence. Due to continuous
change in the position of the sun together with other salient factors, only a fraction of the suns energy
potential is harnessed. The paper is focused on sharing an optimization option that has effectively
addressed a major gap experienced in conventional solar power system installation as applicable to light
emitting diodes traffic light systems. The continuous movement of the sun limits maximum sun light
irradiation absorption and solar trackers are practical solutions to this drawback. The high cost of solar
trackers has however been the major limitation to their adoption. The Introduction of microcontrollerbased
solar tracking systems using Arduino board was found to be cost effective, and it improved the
efficiency of the solar cells significantly. In the study, the maximum power point tracking algorithm was
designed and developed using multiple-axis servo-motor feedback tracking system, which increased the
efficiency of the solar panel array by 23.95%.
