What is a Solar PV Tracker?

A solar tracker is a device that positions a reflector, PV panel (photovoltaic panel)/solar panel, or a solar collector at an optimal angle relative to the sun to receive most of the solar radiation. For example, keeping the solar panel perpendicular to the sun results in more sunlight striking the solar panel, reflecting less light, and absorbing more energy.


Unlike any other single balance-of-system (BOS) component, a solar tracker enhances a PV system’s performance through the constant orientation of the PV panels toward the sun throughout the day.


A stepper motor (a type of DC motor) is usually used to position the solar panel so it can receive maximum sunlight. As the stepper motor is energy efficient with high tracking accuracy, it is used for precise automatic sun tracking with greater solar energy utilization. Moreover, a stepper motor is inexpensive in contrast to a servo motor.


It is estimated that solar tracking increases power output by about 30% to 40%. However, a computer-based algorithm solar tracker needs additional maintenance and is more expensive than a static/fixed solar panel.


Major sun/solar tracking systems are:


Manual solar tracker: Using a manual tracker is only sometimes practical as it requires someone to constantly monitor the sun and physically change the position of the solar panel system.


Active solar tracker: Active trackers use motors or hydraulic cylinders to move the PV panels, so they face the sun. Although active trackers are more convenient to use than manual trackers, a motor’s moving parts could break easily and lead to higher maintenance costs over the system’s lifetime.


Based on the direction of the movement, solar trackers are categorized into:


Single-axis solar tracker: Single-axis trackers are usually used in utility-scale projects, with tracking available on a horizontal/vertical axis. The tracker follows the sun’s position as it moves from east to west. A single-axis solar tracker can increase production from 25% to 35%.



Dual-axis solar tracker: A dual-axis tracker or two-axis tracker not only moves from east to west but also from north to south to track the sun. Such trackers are commonly used for residential and small commercial solar projects with limited space and produce enough power to meet required energy needs.



Passive tracker: Passive solar trackers or passive trackers use a liquid with a low boiling point that evaporates on exposure to solar radiation. Evaporation of the liquid causes the tilt system to become imbalanced, making the panels tilt toward the direction of the sun’s rays.
