Abstract

In a photovoltaic power generating system (1) having a plurality of photovoltaic cells (2), a -sunlight-concentrator device (3) is equipped with a plurality of optical units (4), which are provided with respective primary concentrators with a compound curved surface (5; 23; 27; 30; 31; 32; 34; 37), each of which has an inlet aperture (6) for the direct entry of sunlight, an outlet aperture- (7) for exit of the concentrated sunlight towards a respective photovoltaic cell (2) and an optical axis (8) traversing the inlet aperture (6) and outlet aperture (7). The optical units are seamlessly arranged in an array form.
