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.
These Solar Tracking Systems have an advanced technology which has importance in mounting photovoltaic panels. Stationary mounts, which hold panels in a fixed position, can have their productivity compromised when the sun passes to a less-than-optimal angle. Compensating for this, solar trackers automatically move to “track” the progress of the sun across the sky, thereby maximizing output.
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.
The various types of solar tracking
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.
What is the point of using solar tracking?
There are many vantage points of using the solar tracking system.
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.
Though the maintenance cost is low, the maintenance function has to be authenticated on a regular interval, so that it can run smoothly. These are a bit complicated to handle. So one needs to learn how to handle them properly.
