Abstract

Owing to swift and irrepressible increase in
globalization, the power requirement and energy utilization are also increasing
day by day. To compensate the power needs, various renewable energy sources
which consist solar energy systems are been used in order to satisfy this ample
demand. In order to eliminate the efficiency limits of photo-voltaic panel in a
solar energy system, there are several methods by solar tracking. In this
study, a dual axis solar tracker system is newly designed and tested at several
times to track the sun position. A new approach to solar panel systems has been
investigated and designed in this study via motivation of no sensor and less
mechanical construction. Since a fixed solar panel will not work with the
highest solar radiation at every moment of a day; a mobile system which has
solar tracker can consider that it will work more efficiently. Owing to the
restricted solar radiation reception of fixed panel systems for, a new
fabricate-more efficient solar panel has been designed. Photo-voltaic tracking
mechanism having two axes has been constructed and fabricated. The parts of the
system have selected carefully via the multi decision criteria and boundary
conditions of the system has settled by calculating solar angles. This paper
presents the mentioned design construction detail and -however there is no any
sensor- working results of the tracker whereby the movement of a PV panel was
controlled to setting of programming of a programmable logic-controller (PLC).
To perform the technical task, all electronic circuits and necessary software
have been designed and developed with some opportunities in industry and
Istanbul Technical University. Fabricated this new design tracker works very
well and it is tested with several experimental studies. The results of the experimental
studies represent best performance of the fabricated new design. Due to
results, sensibility for vertical axis movement of the system is stated 1
degree via calculation. Based on the obtained
results this study can conclude that the fabricated new design for a solar dual
axis tracking system offers several advantages concerning the improvement of
efficiency.
