NOVELTY - Combined photovoltaic-optical system for generating electricity from solar radiation comprises: (a) an optical arrangement for concentrating solar radiation, where the optical arrangement comprises: (i) a primary mirror adapted to receive incident solar radiation; and (ii) a secondary mirror disposed in a vicinity of a focal point focal, a vicinity of a focal line, or a vicinity of a focal plane, of the primary mirror; and (b) a photovoltaic panel for generating electricity.    USE - The combined photovoltaic-optical system is used for generating electricity from solar radiation (claimed).    ADVANTAGE - The combined photovoltaic-optical system is less costly to manufacture, and efficiently and economically form electricity from solar radiation.    DETAILED DESCRIPTION - Combined photovoltaic-optical system for generating electricity from solar radiation comprises: (a) an optical arrangement for concentrating solar radiation, where the optical arrangement comprises: (i) a primary mirror adapted to receive incident solar radiation, where the primary mirror is disposed at least along a side of a photovoltaic panel or at a corner of the photovoltaic panel; and (ii) a secondary mirror disposed in a vicinity of a focal point focal, a vicinity of a focal line, or a vicinity of a focal plane, of the primary mirror, where the secondary mirror is adapted to highly concentrate reflected solar radiation received from the primary mirror and to convey the highly concentrated solar radiation as homogenously concentrated solar radiation to the photovoltaic panel; and (b) a photovoltaic panel for generating electricity from both: (i) the homogenously concentrated solar radiation received from the secondary mirrors; and (ii) direct solar radiation received from the sun. An INDEPENDENT CLAIM is included for a method for generating electricity from solar radiation.
