Abstract
Description
Technical Field
[0001] The present application relates to the field of photovoltaic technology, and in particular to a photovoltaic power generation device. Background Art
[0002] Bifacial photovoltaic modules refer to photovoltaic modules that can receive sunlight on both the front and back sides to generate electricity. In practical applications, bifacial photovoltaic modules can use sunlight reflected from the ground, so their power generation capacity is higher than that of single-sided photovoltaic modules. Under standard laboratory test conditions, the front and back sides of the same photovoltaic module are illuminated separately, and the power generation of the front and back sides of the photovoltaic module are measured respectively. The ratio of the back power value to the front power value is defined as the "bifaciality". In practical outdoor applications, the back power generation gain of different photovoltaic modules is not equal to the difference in their bifaciality. The main reasons are: the outdoor light source is natural sunlight, and the irradiation intensity cannot be controlled; and the back side of the photovoltaic module receives radiation mainly from the reflection of the ground surface. The outdoor surface morphology varies greatly, and the reflection of sunlight also varies greatly.

It can be understood that the fourth support member 66 and the third support member 61 are respectively in contact with two opposite sides of the second track 50, but do not affect the movement of the fourth support member 66 and the third support member 61 on the second track 50.
[0059] In some embodiments, the second track 50 includes a third sub-track and a fourth sub-track that are relatively spaced apart from each other, and the second moving member 62 is slidably connected between the third sub-track and the fourth sub-track.
[0060] In some embodiments, the second moving member 62 is a roller.

[0062] The position of the movable component 60 on the first track 30 is limited by the first limit member 71, and the first limit member 71 is arranged on the side of the second track 50 away from the first track 30, which can prevent the movable component 60 from moving to a position too far away from the first track 30 on the second track 50.
