With
the unavoidable shortage of fossil fuel sources in the future, renewable types
of energy have become a topic of interest for researchers, technicians,
investors and decision makers all around the world. New types of energy that
are getting attention include hydroelectricity, bioenergy, solar, wind and
geothermal energy, tidal power and wave power. Because of their renewability,
they are considered as favorable replacements for fossil fuel sources. Among
those types of energy, solar photovoltaic (PV) energy is one of the most
available resources. This technology has been adopted more widely for
residential use nowadays, thanks to research and development activities to
improve solar cells’ performance and lower the cost. According to International
Energy Agency

(IEA),
worldwide PV capacity has grown at 49% per year on average since early 2000s
1, 9. Solar PV energy is highly expected to become a major source of power in
the future.

However,
despite the advantages, solar PV energy is still far from replacing traditional
sources on the market. It is still a challenge to maximize power output of PV
systems in areas that don’t receive a large amount of solar radiation. We still
need more advanced technologies from manufacturers to improve the capability of
PV materials, but improvement of system design and module construction is a
feasible approach to make solar PV power more efficient, thus being a reliable
choice for customers. Aiming for that purpose, this project had been carried
out to support the development of such promising technology.

 

One of the main
methods of increasing efficiency is to maximize the duration of exposure to the
Sun. Tracking systems help achieve this by keeping PV solar panels aligned at
the appropriate angle with the sun rays at any time. The goal of this project
is to build a prototype of light tracking system at smaller scale, but the
design can be applied for any solar energy system in practice. It is also expected
from this project a quantitative measurement of how well tracking system
performs compared to system with fixed mounting method.
