Solar Tracker Sales Expected to Rise Steeply in North America in Coming Years

Dual axis and single axis are the two main types of solar trackers used all over the world. Of these, the usage of the single axis solar trackers was found to be higher in the past. This is ascribed to the large-scale utilization of these trackers in utility solar projects, on account of t

 

  Solar trackers are used for increasing the power output from solar receivers and solar panels. These devices follow the motion of the sun, that is, from east to west every day, and keep the orientation of the solar panels/solar collectors toward the sun. This technique significantly increases the amount of sunlight falling on the solar energy collectors, which in turn, increases the power output. These devices have the ability to improve the energy output of solar panels by nearly 20—30%, thereby enhancing the economies of the overall solar energy project.  

One of the key factors fueling the demand for solar trackers is the increasing requirement of solar energy in commercial, industrial, and residential applications. Moreover, there has been a drastic shift toward the use of solar energy over the last few years, primarily due to the increasing emissions and environmental damage caused because of the large-scale utilization of fossil fuels to generate power. In addition to this, many people are increasingly adopting solar trackers for residential purposes, mainly for increasing electricity conversion rates. 

Commercial, residential, and utility are the major application areas of solar trackers all over the globe. Out of these, the utilization of solar trackers is presently being observed to be significantly higher in utility applications. This is credited to the fact that the usage of these trackers increases the electricity generation by as much as 40% in some areas depending on the amount of sunlight. These trackers also increase the electricity generation by nearly one-third as compared to the power produced by the fixed modules. 

Globally, North America is currently observing the highest usage of solar trackers. This is attributed to the rapidly declining prices of solar panels and the increasing enactment of strict environmental policies and regulations in many North American countries for mitigating the carbon emission levels. For example, “as per the National Renewable Energy Laboratory (NREL), module costs for commercial PV systems decreased from USD 1.88/W in 2017 to USD 1.83/W in 2018, witnessing a decline of around 3%”.
