This document presents information on solar trackers. It defines a solar tracker as a device that orients solar panels towards the sun using light sensors. It works by having sensors detect the sun's position and motors adjusting the panel accordingly. There are two main types - single-axis trackers rotating on one axis, and dual-axis trackers rotating on two axes, which are more efficient. Solar trackers increase energy output by up to 40% but are more expensive and require maintenance compared to fixed panels. In conclusion, they are a more efficient approach that uses sensors to constantly adjust the panel positioning.
