Question
What is a solar tracker?
A fancy name for a watch
A pacemaker that measures how sunburned you are
A device that moves so as to aim a collector of solar energy at the sun
An app that will track how much energy your solar panels have produced
The correct answer is: A device that moves so as to aim a collector of solar energy at the sun
Solar Trackers are used to keep solar collectors/solar panels oriented directly towards the sun as it moves through the sky every day. Using Solar Trackers increases the amount of solar energy which is received by the solar energy collector and improves the energy output of the heat/electricity which is generated.
