As tracker companies continue to strive to achieve the market goals of reducing installed cost and increasing energy generation, innovations have resulted in a fundamentally more technologically advanced set of products. No longer simple state machines that follow a tilt algorithm and react passively to environmental conditions, today's trackers incorporate data from a myriad of sensors (both internal and external to the tracker), make decisions that best optimize reliability performance and energy generation, and inform stakeholders in real time as to their behavior. Trackers are leading the way in industrial Internet of Things (IoT) development.
