Abstract:
The dual threats of energy depletion and global warming place the development ol
methods for harnessing renewable energy resources at the Centre of public interest. The world is
using up all the resources to meet the daily demands of energy and it is quite expectable that in
the near future we will run out of any naturally occurring ore/mineral/petroleum. As a result,
renewable energy solution has achieved a great demand today to save the natural resources and
also to tackle the crisis of energy. Solar energy is rapidly gaining its popularity as an important
source of renewable energy. It is one of the most promising renewable energy resources. Sun
trackers can substantially improve the electricity production of a photovoltaic (PV) system.
Development of solar panel tracking system has been ongoing for several years. Now
the wheel which is fixed at the base will move the panel from the shaded region to solar
illuminated region, by using a sensor to detect high intensity radiation from the
But the efficiency of solar panel is a big factor. While the sun keeps following a
parabolic path throughout the day. the panels which are used in our country are generally fixed to
a pole or the roof of the house and hence, throughout the day. the efficiency decreases
significantly.
Therefore I have constructed a 2 axis solar tracker w hich can track the sun throughout the day to
obtain the maximum efficiency.
