NOVELTY - The system (100) has a first receiver (150) comprising photovoltaic solar cells for generating electricity from a visible beam (125). A second receiver (160) generates heat and/or electricity from an infrared beam (135). A reflector directs incident solar radiation (105) to an optical filter (140). The optical filter splits the solar radiation into the visible beam and the infrared beam. The visible beam is directed to the first receiver to generate electricity. The infrared beam is directed to the second receiver to generate the electricity and/or heat.    USE - Concentrating solar energy collection system for collecting solar energy to provide electrical energy and thermal energy.    ADVANTAGE - The system can split the solar radiation into a visible band and an infrared band using the optical filter and separately direct distinct wavelength bands to specifically tailored receivers, so that efficient collection of total quantity energy output from the first and second receivers can be increased. The system reduces extraneous radiation at the receiver to reduce damage over extended periods. The first receiver, the optical filter and the second receiver can be rotated or positioned independently each other or independently of a trough reflector so as to increase solar energy collection efficiency.    DETAILED DESCRIPTION - The first receiver and second receiver are a photovoltaic-thermal solar receiver and solar thermal collector. The optical filter is a dichroic filter, a dichroic beam splitting cube, a prism or a diffraction grating. An INDEPENDENT CLAIM is also included for a method for generating electrical energy and/or thermal energy from solar radiation.
