SPECTRUM project

A prototype of the solar energy transport system has been created with which the supply of energy in a building has been tested. The basic module of the system is composed of 4 collectors each coupled to a fiber. The fibers are then collected in a bundle and the transported energy can be used for different uses selectable by an optical diverter. The applications tested are: room lighting, water heating and electricity generation. For this last use, a photovoltaic panel transforms solar energy into electrical energy, which can be stored in a battery for later use.

A schematic of the optical deviator is presented in the figure below

The beam of light coming out of the fibers is directed through the optical deflector (OS) to one of the possible uses. The diverter consists of a spherical mirror (SM) and a stepper motor to rotate the mirror

The figure below shows how the light collected by the tiles placed on the roof of a house can be used for lighting, using the fiber output directly, or used for heating the water or as an alternative source of electricity.
