Ray-tracing techniques

Definition

Ray-tracing techniques refer to a method used to simulate the path of rays of light as they interact with surfaces and objects in a solar field. This approach helps in accurately modeling how sunlight is concentrated by mirrors or lenses to optimize the design and layout of solar power systems. By utilizing these techniques, designers can maximize energy capture and ensure that every part of the solar field operates efficiently.
