Optical simulation of a parabolic solar concentrator

This work presents a 3D ray tracing approach for the optical simulation of a parabolic solar conc entrator for a thermo-magnetic (Curie motor) experiment. An approach based on Snell’s law of reflection (geometrical optics) in vector form is used in this study. We consider the solid angle of the s un through a rotation of the concentrator around an axis. This paper aims to set up a digital technical tool as flexible as possible for applications in the field of renewable energy. Mathematical modelling as well as numerical simulation in Python environment are presented. The aim of the proposed algorithm is to be used for the concentration of light rays on any optical system, symmetrical or not. Better yet, offers a solar tracking model.
