Technical Field

The present invention relates to a method for mounting a solar cell module, and more particularly, to a solar cell module in which a fastening portion of an elastic member in a reinforcing structure can be easily aligned to a desired position of a frame.

Background

Solar cells, which are photoelectric devices that convert light energy into electrical energy, are one of the important alternative energy sources due to low pollution and low cost, and the fact that solar energy, which is not an absolute source, can be used as an energy source. The basic structure of the solar cell is formed by bonding a P-type semiconductor and an N-type semiconductor, when sunlight irradiates a solar substrate with the P-N junction, light energy excites electrons in silicon atoms to generate convection of electrons and holes, and the electrons and the holes are respectively gathered at two ends of a negative electrode and a positive electrode under the influence of a built-in electric field formed at the P-N junction, so that voltage is generated at two ends of the solar cell. At this time, the electrodes can be used to connect two ends of the solar cell to an external circuit to form a loop, and further to generate current, which is the principle of solar cell power generation.

The solar cell module includes many materials, such as a front glass plate, a first encapsulant, a plurality of solar cells, a second encapsulant, a back sheet, and the like. At present, the solar cell module is exposed to the open air when in use, and except for receiving the direct acting force of strong wind, the stress and the shearing force generated by temperature rise and drop caused by the sun exposure, the solar cell module is required to bear the weight of accumulated snow when in use in cold weather, and the like, which are factors possibly causing the disintegration of the whole structure.

Referring to fig. 1, in order to increase the strength of the overall structure of the solar cell module 9, a stiffener 92 may be installed on the back side 901 of the solar cell module 9 on the aluminum frame 91 to strengthen the overall structure, and screws 921 are locked on the side 911 of the aluminum frame 91 to fix the stiffener 92. However, the reinforcing ribs 92 are not easily aligned with the desired positions of the aluminum bezel 91 during mounting, and the larger the number of reinforcing ribs 92, the more the mounting time and cost increase.

Therefore, it is desirable to provide a solar cell module and a method for mounting the same, which can solve the above-mentioned problems.

The solar cell module 1 includes a photovoltaic laminate 10, a plurality of frames 11, a reinforcing structure 12, a first elastic element 13 and a connecting element 14. For example, the photovoltaic laminate 10 can include a front glass sheet, a back sheet, at least one solar cell, and an encapsulant. The solar cell is positioned between the front glass plate and the back plate. The packaging material is also positioned between the front glass plate and the back plate and wraps the at least one solar cell.

Please refer to fig. 4, which is an exploded cross-sectional view illustrating a solar cell module according to an embodiment of the invention. The frames 11 are disposed around the photovoltaic laminate 10. For example, the periphery of the photovoltaic laminate 10 can be fixed in the grooves 110 of the frames 11 by adhesive (not shown). The material of the frames 11 may be metal, such as aluminum. The frames 11 include first and second frames 111, 112 opposite to each other, the first frame 111 may include a first positioning hole 1111, and the second frame 112 may also include a second positioning hole 1121. The first and second positioning holes 1111, 1121 can be circular holes, for example, formed by punching or laser.

The first elastic element 13 is disposed near the first end 121 of the reinforcing structure 12, and includes a first fastening portion 131, and the first fastening portion 131 is used for fastening in the first positioning hole 1111 of the first frame 111. For example, referring to fig. 2a, the first end portion 121 of the reinforcing structure 12 is inserted into the first frame 111, and the reinforcing structure 12 is rotated along a rotation direction D1 to press the first locking portion 131 of the first elastic element 13, so that the first elastic element 13 generates a reverse elastic force.
