Theoretical Deduction of the Optimum Tilt Angles for Small-Scale Linear Fresnel Reflectors

A theoretical justification and computation of the optimum values of the two longitudinal tilt angles of a small-scale linear Fresnel reflector is provided. The optimum angle of the mobile structure is proved to be half the latitude of the geographic location, while the optimum angle of the secondary reflector system is proved to be equal to that latitude. Brute-force verification is carried out for five EU cities, each in one of the five European climate zones.

Automated summary

This study presents a theoretical justification and computation of the optimum values of two longitudinal tilt angles for a small-scale linear Fresnel reflector. It is found that the optimum angle for the mobile structure is half the latitude of the geographic location, while the optimum angle for the secondary reflector system is equal to that latitude. Additionally, brute-force verification is conducted for five EU cities to validate the findings.
