This study presents a simulation based optimization study of a Linear Fresnel Collector with a trapezoidal multi tube cavity receiver. The study focuses on harvesting the maximum daily solar energy (maximizing plant optical efficiency throughout a summer's day), while minimizing plant thermal heat loss (maximizing plant thermal efficiency), as well as plant cost (the economic optimization of the plant), which leads to the generation of cheaper solar electricity from an LFC plant.
