Reflective Trough Focusing Solar Collector
How Parabolic Trough Systems Work: An Overview
The key component of any solar thermal power system is the solar collector, which is responsible for concentrating the sunlight onto the receiver. There are several different types of solar collectors, including parabolic troughs, power towers, and dish/engine systems. Each type of collector has its own unique design and operating principles.
