Abstract
The invention relates to a photovoltaic assembly having a junction box arranged in the middle, which comprises a photovoltaic assembly shell and a junction box arranged on the photovoltaic assembly shell; the junction box is arranged in the middle of the photovoltaic assembly shell; the inner part of the photovoltaic assembly is provided with a loop consisting of a plurality of solar cells and bypass diodes connected in series; and the positive electrode and the negative electrode of the loop are led out of the photovoltaic assembly through the junction box. The photovoltaic assembly can realize the difference of the appearance of the product, can well solve the problems that a bracket is easy to shield the junction box of the assembly, the assembly is inconvenient to maintain, and the like, and can shorten the length of a cable in the junction box so as to save the cost.
Description
Technical field
The present invention relates to a kind of photovoltaic module, especially a kind of terminal box is installed in the photovoltaic module at middle part.
Background technology
Existing crystal silicon flat plate photovoltaic component is installed in terminal box the end of assembly usually, and it is relatively simple for structure, installs also more convenient.If but when the user had the special mounting demand, the drawback of this assembly had just shown, it is long that main drawback has the cable of terminal box to need, and mounting bracket covers the terminal box of assembly easily, maintenance assembly inconvenience etc.If terminal box is installed in the middle part of assembly, just can fine solution support cover the terminal box of assembly easily, problems such as maintenance assembly inconvenience also can shorten the length of terminal box cable simultaneously, save cost.In addition, compare, can also realize the differentiation of product appearance with the assembly that terminal box is placed on the end.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of easy to maintenancely, can shorten the photovoltaic module of the length of terminal box cable.
The technical solution adopted in the present invention is: a kind of terminal box is installed in the photovoltaic module at middle part, comprise the photovoltaic module shell and be arranged on terminal box on the photovoltaic module shell, described terminal box is installed in the middle part of photovoltaic module shell, the inside of described photovoltaic module is provided with the loop that is made of the solar cell of a plurality of series connection and bypass diode, and the positive pole in described loop and negative pole lead to the photovoltaic module outside by terminal box.
Further, according to the needs of the shape or the space size of terminal box, the horizontal or vertical placement of solar cell of the present invention is connected on photovoltaic module inside.
The invention has the beneficial effects as follows: compare with the assembly that terminal box is placed on the end, can realize the differentiation of product appearance; The terminal box that can fine solution support covers assembly easily, problems such as maintenance assembly inconvenience; Can shorten the length of terminal box cable, save cost.

Embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of terminal box as shown in Figure 2 is installed in the photovoltaic module at middle part, comprise photovoltaic module 1 shell and be arranged on terminal box 2 on the photovoltaic module shell, described terminal box 2 is installed in the middle part of photovoltaic module 1 shell, this structure that is installed in the middle part is compared with prior art shown in Figure 1, the terminal box that can fine solution support covers assembly easily, problems such as maintenance assembly inconvenience.
The inside of photovoltaic module is provided with the loop that is made of the solar cell of a plurality of series connection and bypass diode, and the positive pole in described loop and negative pole lead to the photovoltaic module outside by terminal box.Shown in Figure 3 is the vertical a kind of enforcement circuit diagram that is connected on photovoltaic module inside of placing of solar cell, and 72 solar cells are connected one by one and formed the loop, are in series with 3 bypass diodes between the positive pole in loop and the negative pole again.
And shown in Figure 4 be another embodiment, be 72 solar cells to be connected one by one form the loop, and lie in a horizontal plane in photovoltaic module inside, be in series with 3 bypass diodes again between the positive pole in same loop and the negative pole.
Just the specific embodiment of the present invention of describing in the above specification, various not illustrating is construed as limiting flesh and blood of the present invention, the person of an ordinary skill in the technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
