Global
warming has increased the demand and request for green energy produced by
renewable sources such as solar power. Consequently, solar tracking is
increasingly being applied as a sustainable power generating solution.
Solar
Tracking System is a device for orienting a solar panel or concentrating a
solar reflector or lens towards the sun. Concentrators, especially in solar
cell applications, require a high degree of accuracy to ensure that the
concentrated sunlight is directed precisely to the powered device. Precise
tracking of the sun is achieved through systems with single or dual axis
tracking.
But
before we discuss further about solar tracking systems, we need to know; what
exactly solar tracking is about.
Solar Tracking is an obvious way to improve
the efficiency of solar power plants. As the sun moves across the sky an
electric actuator system makes sure that the solar panels automatically follow
and maintain the optimum angle in order to make the most of the sunbeams. Tracking
the sun from east in the morning to west in the evening will increase the
efficiency of the solar panel up to 45%. With almost no maintenance cost you
can expect full return on your investment. That is why; solar tracking is a
good way to increase and to produce solar energies than the other ways of doing
it.
Different Varieties Of Solar Tracking
Systems
There
are different ways in which one can do solar tracking. There are variations in
solar panels or solar trackers. Before using them, one needs to know about the
variations of the trackers.
There
is a single axis solar tracking system, where the panels can turn around the
center of the axis and can face the sun throughout the day to consume energy.
Then
there is dual axis solar tracking system. Dual axis tracking is typically used
to orient a mirror and redirect sunlight along a fixed axis towards a
stationary receiver. But the system can also gain additional yield on the PV
cells.
Why One Should Use Solar Tracking Systems?
There
are many advantages of using the solar
tracking system. They are as follows.
Solar Trackers
generate more electricity than their stationary counterparts due to an
increased direct exposure to solar rays.
There
are many different kinds of solar tracker, such as single-axis and dual-axis
trackers, which can help you find the perfect fit for your unique job site.
Installation size, local weather, degree of latitude, and electrical
requirements are all important considerations that can influence the type of
solar tracker that’s best for you.
Solar
trackers generate more electricity in roughly the same amount of space needed
for fixed tilt systems, making them ideal optimizing land usage.
There
are certain disadvantages of using them too.
Solar
trackers are slightly more expensive than their stationary counterparts, due to
the more complex technology and moving parts necessary for their operation.
But,
this is not much of a disadvantage keeping in mind the advantages it has. So,
using a solar tracking system is a good ideas.
