Embodiment Construction

[0017] Give an embodiment below in conjunction with accompanying drawing: as figure 1 As shown, the reflective concentrator 1 of the reflective concentrating solar photovoltaic power generation device is composed of a group of 8 plane mirrors installed together, of which 5 are fixed plane mirrors 2, and 3 are rotating plane mirrors 3 that can change the angle. A photovoltaic cell 5 is fixed on the opposite side of the reflective concentrator 1 by a support rod 4 ; a support frame 6 is fixed under the reflective concentrator 1 . The plane mirrors 2, 3 have a larger area than the photovoltaic cell 5 and are similar in shape. The light-receiving surface of the photovoltaic cell 5 faces the reflective concentrator 1 , and a heat sink 7 is installed on the back and faces the sunlight. The sun tracker 8 that drives the whole device to rotate is housed on the support frame 6 .

[0018] Such as image 3 As shown, each rotating plane mirror 3 is fixedly connected in the rectangular ...

Abstract

The invention discloses a reflection focusing solar energy photovoltaic power generation device. The device is mainly characterized in that a reflection condenser of the device is formed by a group of flat mirrors which are mounted together, in which one part of the flat mirrors are fixed flat mirrors, and the other part of the flat mirrors are rotating flat mirrors which can change angle; each rotating flat mirror is fixedly connected into a rectangular picture frame through a rotating shaft; the photovoltaic cell is fixed by a supporting rod on the opposite of the reflection condenser; and a supporting frame is fixed under the reflection condenser. According to the reflection focusing solar energy photovoltaic power generation device, the flat mirrors with low cost are used for converging solar light, according to the intensity and environment temperature of solar light, the concentration ratio of the reflection condenser is adjusted by dismounting or adjusting the reflection angles of a part of flat mirrors, and the total quantity of solar light reflected onto the photovoltaic cell is controlled, so that illumination on the photovoltaic cell remains optimal.

Description

technical field [0001] The invention relates to a reflective and concentrating solar photovoltaic power generation device, in particular to a reflective and concentrating solar photovoltaic power generation device capable of improving the utilization rate of solar photovoltaic cells and having an adjustable concentration ratio. Background technique [0002] At present, there are two problems to be solved in the widely used solar photovoltaic power generation process: one is that the energy density of sunlight is too low, while the cost of photovoltaic cells per unit area is very high, which causes the cost of solar photovoltaic power generation to be too high and lose The economic competitive advantage with conventional energy sources; second, because the intensity of sunlight varies greatly at different times, resulting in instability of solar power generation power, and all equipment in the power generation system must be equipped according to the peak power, and the system...
