A sunlight collector module is disclosed, capable of collecting the sunlight from the sun for the illumination at a certain position, and of reflecting portion of the sunlight to a solar photovoltaic module. The disclosed sunlight collector module comprises: a base, a first reflective element disposed on the base, a second reflective element, a light-guide element, and a beam splitting element, wherein the second reflective element is disposed on a side, which is opposite to the base, of the first reflective element. Besides, the light-guide element disposed on a side, which is opposite to the second reflective element, of the first reflective element. In addition, the beam splitting element is disposed between the first reflective element and the light-guide element, for reflecting portion of the sunlight to the solar photovoltaic module. The non-reflected portion of the sunlight passes through the beam splitting element and enters the light-guide element.
