The present invention provides an apparatus capable of dividing light of various wavelengths included in solar light based on characteristics to simultaneously obtain electric energy and thermal energy at a very high efficiency. According to the present invention, a solar energy acquisition system includes: a primary reflection mirror having a parabolic mirror structure in which a through hole is formed in a central region and solar light is primarily collected; a secondary reflection mirror disposed in front of the primary reflection mirror within a focal distance of the primary reflection mirror, secondarily collecting light having a wavelength contributing to the power generation among solar light collected by the primary reflection mirror to reflect the light toward the through hole, and absorbing light having a wavelength that does not contribute to the power generation; a power generating unit installed in the through hole and including a plurality of solar cells for generating electricity by using solar light which is secondarily collected; a solar light guiding unit installed in front of the power generating unit to guide the solar light secondarily collected by the secondary reflection mirror, to each solar cell; a cooling unit coupled to a rear surface of the power generating unit to cool the power generating unit; a heating medium heating unit coupled to a rear side of the secondary reflection mirror for heating a heating medium by absorbing heat of the solar light absorbed by the secondary reflection mirror; and a connection part vertically penetrating the cooling unit to fix the secondary reflection mirror and the heating medium heating unit and to circulate and supply the heating medium to the heating medium heating unit. 본 발명은 태양광에 포함되어 있는 여러가지 파장의 빛을 그 특성에 맞추어 분할하고, 이를 활용하여 전기에너지와 열에너지를 매우 높은 효율로 동시에 획득하는 장치에 관한 것으로서, 본 발명에 따른 태양에너지 획득장치는, 중앙 영역에 통공이 형성되며, 태양광을 1차 집광하는 포물 거울 구조의 1차 반사경; 상기 1차 반사경의 전방 중 상기 1차 반사경의 초점거리 이내에 배치되며, 상기 1차 반사경에 의하여 집광되는 태양광 중 발전에 기여하는 파장의 빛을 2차 집광하여 상기 통공 방향으로 반사하고 발전에 비기여하는 파장의 빛을 흡수하는 2차 반사경; 상기 통공에 설치되어 2차 집광된 태양광을 이용하여 전기를 생산하는 다수개의 태양전지셀을 구비하는 발전부; 상기 발전부 전방에 설치되며, 상기 2차 반사경에 의하여 2차 집광된 태양광을 상기 태양전지셀 별로 안내하는 태양광 안내부; 상기 발전부의 후면에 결합되어 설치되며, 상기 발전부를 냉각시키는 냉각부; 상기 2차 반사경 후측에 결합되어 설치되며, 상기 2차 반사경에 의하여 흡수되는 태양광의 열을 흡수하여 열매체를 가열하는 열매체 가열부; 상기 냉각부를 수직으로 관통하여 설치되며, 상기 2차 반사경 및 열매체 가열부를 고정시키고 상기 열매체 가열부에 열매체를 순환 공급하는 연결부;를 포함한다.
