PHOTOVOLTAIC SYSTEM WITH DOUBLE REFLECTION SOLAR CONCENTRATOR

摘要

A photovoltaic system (1) having a curved primary reflector (30) for collecting and concentrating sunlight, a flat secondary reflector (4) for reflecting at least part of the sunlight concentrated by the primary reflector (3; 30), a lens (9), which has a curved front surface (10) having an input portion (11) for receiving the sunlight concentrated by the primary reflector (3) and a flat rear surface (12) coupled with the secondary reflector (4), and a light guide (13), which has an input section (14) coupled with the front surface (10) of the lens (9) and an output section (15) coupled with a photovoltaic converter (8). The input portion (11) of the lens (9) is shaped in such a way that after having been reflected by the secondary reflector (4), the sunlight which entered the lens (9) is concentrated in a focal area (F) located in the input section (14) of the light guide (13).
