In addition, the first auxiliary rib 220a, the second auxiliary rib 220b, and the third auxiliary rib 220c and the solar cell module 100 further include an adhesive layer 230 respectively, so that the first auxiliary rib 220a, the second auxiliary rib 220b, and the third The auxiliary rib 220c is attached to the solar cell module 100 as shown in FIGS. 4 and 5. In detail, since the solar cell module 100 has a property of being weak in texture, and the first auxiliary rib 220a, the second auxiliary rib 220b, and the third auxiliary rib 220c have a relatively high hardness, the solar cell module is not only made by using the adhesive layer 230. The force of the group 100 can be uniformly dispersed to the frame structure 200, and the adhesive layer 230 can also absorb the stress generated by the first auxiliary rib 220a, the second auxiliary rib 220b and the third auxiliary rib 220c to support the solar cell module 100.

As described above, the thickness of the substrate 120 of the solar cell module 100 may be less than 1.0 mm. In general, the weight of the solar cell module 100 is reduced compared to a conventional solar cell module having a substrate thickness of at least 3.0 mm, but the mechanical strength of the substrate 120 is also reduced, and the center of the substrate 120 is also reduced. It is prone to severe bending. In view of this, in the solar device 10 of the present embodiment, the transmission frame structure 200 has the first auxiliary rib 220a, the second auxiliary rib 220b, and the third auxiliary rib 220c, and the first auxiliary rib 220a and the second auxiliary rib 220b And the third auxiliary ribs 220c respectively include a first I-shaped body 222 and a pair of first fixing portions 224a, 224b, whereby when the solar device 10 is subjected to an external force, the first auxiliary rib 220a, the second auxiliary rib 220b and the first The three auxiliary ribs 220c can not only disperse the stress and shear force received by the solar cell module 100, but also increase the stress strength that the solar device 10 can withstand. As a result, the solar device 10 of the present invention has a good mechanical strength while achieving a reduction in thickness of the transparent substrate 120 of less than 1.0 mm.

Hereinafter, the features of the present invention will be more specifically described by performing a mechanical load simulation test using an embodiment of the solar device 10. While the following examples are described, the invention should not be construed restrictively by the examples described below.

The mechanical load simulation test is a calculation of the deformation amount of the solar device 10 using the Abaqus simulation software, wherein the simulation test condition is: uniformly and vertically when the elastic modulus of the auxiliary rib is set to 65 GPa and the Poisson's ratio is set to 0.33. Providing a pressure of 5400 Pa to the front side or a pressure of 2400 Pa to the back side; and the solar device 10 used is: the thickness of the substrate 120 is 0.85 mm, and the distance D1 And an example in which the distance D4 is 33 cm, the distance D2 and the distance D3 are 43.3 cm, and the weight is 10.5 kg, and the calculation results are shown in Table 1.

In addition, under this simulation condition, a comparative experiment is to perform a mechanical load simulation test on the solar device 10 after removing the first auxiliary rib 220a, the second auxiliary rib 220b, and the third auxiliary rib 220c. The simulation results show that whether the pressure of 5400 Pa is provided on the front side or the pressure of 2400 Pa on the back side causes cracking of the substrate 120, which causes the solar device 10 to fail. In short, if the conventional solar device does not have an auxiliary rib, the substrate cracking problem cannot be overcome. In addition, according to different customers' demand for products, there are different specifications. The high standard requires simulation results to provide 5400Pa under the pressure on the front side, and the deformation amount is below 25.00mm to meet the product demand; while under the pressure of 2400Pa on the back side The deformation amount is less than 12.00mm to meet the product requirements. The usual standard requires that the simulation result meets the product requirements under the pressure of 5400 Pa on the front side and the deformation amount of 27.00 mm or less. Under the pressure of 2400 Pa on the back side, the deformation amount is 13.00 mm or less to meet the product requirements.

Based on Table 1, it can be seen that in the embodiment, the solar device 10 having a thickness of 0.85 mm and a weight of only 10.5 kg is still within the normal specifications of the product, but still has an improved space in mechanical strength to meet the requirements. High standard product requirements standard.

That is, when the first fixing portions 224a, 224b are disposed at the top portion 222a of the first I-shaped body 222, the auxiliary ribs (the first auxiliary rib 220a, the second auxiliary rib 220b, or the third auxiliary rib 220c) are larger Moment of inertia.

Through the verification of the Pro-E simulation software, it can be obtained that when the first fixing portions 224a, 224b are disposed at the center of the first I-shaped body 222 (as shown in FIG. 4), the moment of inertia is 15157 kg. m ² ; and when the first fixing portion 224a, 224b is disposed at the top 222a of the first I-shaped body 222 (as shown in FIG. 6), the moment of inertia is 17078 kg. m ² . Therefore, as a result of the simulation verification, it is understood that the first fixing portions 224a, 224b are preferably disposed on the top portion 222a of the first I-shaped body 222.

In other embodiments, the alignment groove 226 may also be disposed at the top 222a of the first I-shaped body 222.

Except that the solar device 30 is used for the simulation test, the amount of deformation is calculated under the same conditions and manner as when the solar device 10 is subjected to the simulation test, and evaluated by the same standard, wherein the solar device 30 is: the substrate 120 has a thickness of 0.85. Mm, distance D1 and distance D4 are 33cm, distance D2 and distance D3 are 43.3cm, weight is 11.25kg, and extend outward from the second auxiliary rib 220b, sub-brackets 400a, 400b, 400c, 400d, 400e, 400f, 400g The examples of 400h, 400i, 400j, 400k, and 400l are respectively 125 mm, and the results are shown in Table 3.

Based on Table 1, Table 2, and Table 3, compared to the solar device 10 and the solar device 20, the sub-brackets 400a, 400b, 400c, 400d, 400e, 400f, 400g, 400h, 400i, 400j, 400k, 400l are provided. The solar device 30 has the best mechanical strength and weighs only 11.25 kg.

In summary, in the solar device of the embodiment of the present invention, the through frame structure has three auxiliary ribs, and each of the auxiliary ribs includes an I-shaped body and a pair of fixing portions, so that even the substrate of the solar cell module Thickness less than 1.0mm, sun The energy device still has good mechanical strength. That is to say, the solar device of the present invention has both good mechanical strength and a lightweight design. Further, in the solar device of the present invention, the auxiliary rib can be coupled to the outer frame through the pair of fixing portions, whereby the members of the solar device can be effectively simplified and the erection time can be shortened. In addition, the mechanical strength of the solar device can be further improved by providing a sub-bracket connected to the auxiliary rib.
