1. What is a solar tracker?A solar tracker is a device that moves solar panels or mirrors so they always face the sun, helping them collect more sunlight.
2. How does a solar tracker help solar panels?By keeping the panels perpendicular to the sun’s rays, it reduces the angle of incidence, which means the panels can absorb more energy and work better.

Angle of Incidence: The angle between a ray of light and a line perpendicular to the surface it strikes.
Levelized Cost of Energy (LCOE): The average net present cost of electricity generation for a plant over its lifetime.
Heliostat: A mirror that turns so as to keep the Sun's rays reflected constantly upon a particular object.
