A concentrating solar apparatus, comprising two light receiving devices (110, 120). The first light receiving device (110) has a substantially horizontal first light receiving surface (111). The second light receiving device (120) has a second light receiving surface (121) that is substantially vertical with respect to the first light receiving surface (111). The first light receiving device (110) is a light energy utilization device, or is a combination of the light energy utilization device and a light guide device. The second light receiving device (120) is a Fresnel lens. Due to the relative position relationship between the second light receiving device (120) and the first light receiving device (110), sunlight is irradiated to the first light receiving surface (111) after passing through the second light receiving surface (121). By providing a substantially vertical Fresnel lens on a light path in front of the light energy utilization device, the apparatus can adapt to deflection of a relatively large angle of the sun without actively tracking the sun, and therefore has extremely high cost performance.
