Problems solved by technology

[0005] (1) In the case of relatively limited layout area of ​​photovoltaic modules, the number of solar cells that each photovoltaic module can accommodate is also very limited
[0006] (2) The structure of photovoltaic modules is simple, and the reflection of light leads to excessive energy loss, which restricts the power generation of photovoltaic modules to a certain extent

Embodiment 1

[0039] like Figure 1~3As shown, it is an assembled angle-adjustable folding-plate photovoltaic module of the present invention. The overall shape is rectangular and flat. ), a battery string formed by a number of solar cells 3, a hot melt adhesive layer (omitted in the figure) and a back sheet 4. It is a glass plate, and the front glass 2 and the back plate 4 are mainly composed of a plurality of V-shaped units 5 connected in sequence in the transverse direction (along the short side, in other embodiments, it can be vertically, that is, along the long side) The folding plate structure, the front glass and the V-shaped unit 5 of the back plate 4 correspond up and down, and the space between the inclined panels 6 and 7 that constitute the V-shaped unit 5 is the space for placing the solar battery sheet 3. Each inclined panel of the V-shaped unit 5 The panels 6 , 7 correspond to a row of solar cells 3 , and the solar cells 3 face the corresponding inclined panels 6 , 7 . Be hi...

Embodiment 2

[0045] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the angle adjustment mechanism is different. In this embodiment, the angle adjusting machine includes a pulley 14 with a built-in motor and an adjusting rod 15. One of the inclined plates of the V-shaped unit is provided with a bar-shaped groove 13 extending obliquely near its end surface. The pulley 14 is located on the bar. In the bar-shaped groove 13, the notch of the bar-shaped groove 13 is a bar-shaped narrow mouth to limit the pulley in the bar-shaped groove 13, and the pulley 14 is rotatably installed on the rotating shaft (not shown in the figure), and one end of the adjusting rod 15 is hinged On the edge of the other inclined plate, the other end is connected with the rotating shaft, and the pulley 14 rotates under the drive of the motor and moves in the bar-shaped groove 13 so as to automatically adjust the angle α between the two inclined plates.

Embodiment 3

[0047] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the photovoltaic module of this embodiment is bent downwards in the transverse direction (in other embodiments, it can also be in the longitudinal direction) (in other embodiments, it can also be Bending upward) so that the front glass 2 and the back plate 4 become concave (in other embodiments, may also be convex) curved plates. The advantage of the photovoltaic module of this embodiment is that as the sun moves, there are solar cells facing the optimal irradiation direction at each angular position of the photovoltaic module, which increases solar energy absorption.

[0048] In this embodiment, the photovoltaic module is curved, and the included angles of the two inclined panels of all the V-shaped units can be the same, or partly the same, and partly different, which can be determined according to the actual situation.

[0049] In fact, the curved shape of the entire photovoltai...

Abstract

The invention discloses an assembled angle-adjustable folded-plate-shaped photovoltaic module and a photovoltaic system thereof. The photovoltaic module comprises front glass, a battery string formedby connecting a plurality of solar cells and a back plate, which are sequentially arranged from top to bottom. The front glass and the back plate are respectively of a folded plate structure which ismainly composed of a plurality of V-shaped units which are connected in sequence, the V-shaped units of the front glass and the V-shaped units of the back plate correspond to each other up and down, spaces for placing the solar cells are formed in inclined panels which form the V-shaped units, and the solar cells face the corresponding inclined panels; the two inclined panels of each V-shaped unitare hinged, that is, each inclined panel of the front glass and each inclined panel of the back plate corresponding to each other up and down and the solar cell between the inclined panels form a spliced unit; and an angle adjusting mechanism for adjusting an included angle is arranged on each V-shaped unit. The assembled angle-adjustable folded-plate-shaped photovoltaic module is of a folded-plate-shaped structure, the included angle of each V-shaped unit is adjustable, and the generating capacity of the module is improved; and the module is formed by splicing the spliced units, so that themodule is convenient to store and transport, and repair and replacement of the module are facilitated.

Description

technical field [0001] The present invention relates to a photovoltaic assembly, in particular to an assembled angle-adjustable folded-plate photovoltaic assembly, and to a photovoltaic system composed of the assembled angle-adjustable folded-plate photovoltaic assembly. Background technique [0002] A solar cell is a device that effectively absorbs solar radiation and uses the photovoltaic effect to convert light energy into electrical energy. When sunlight shines on the semiconductor P-N junction, new hole-electron pairs will be formed. Under the action of the electric field of the P-N junction, the holes flow from the N region to the P region, and the electrons flow from the P region to the N region. After the circuit is turned on A current will be generated. [0003] Crystalline silicon solar photovoltaic modules are the main form of solar cells in practical applications, and they are the mainstream products in the photovoltaic market today. Crystalline silicon solar p...
