Embodiment
Below in conjunction with the drawings and specific embodiments, technical solution of the present invention is described in detail, further to understand object of the present invention, scheme and effect, but not as the restriction of claims protection range of the present invention.
Please refer to Fig. 1 ~ Fig. 2.Fig. 1 illustrates the stereogram of the solar module 100 according to an embodiment of the present invention.Fig. 2 illustrates the partial exploded view of the backboard 110 (Fig. 1 does not show) of Fig. 1, cover plate 120, solar cell 130 and encapsulation material 140 (Fig. 1 does not show).As shown in Fig. 1 ~ Fig. 2, solar module 100 comprises backboard 110, cover plate 120, at least one solar cell 130 and at least one encapsulation material 140.Backboard 110 has at least one backboard perforation 112.Cover plate 120 relatively backboard 110 is arranged, and cover plate 120 has at least one cover plate perforation 122.Solar cell 130 is between backboard 110 and cover plate 120.Encapsulation material 140 is between backboard 110, between cover plate 120 and solar cell 130, and encapsulation material 140 has at least one encapsulation material perforation 142.Encapsulation material perforation 142 is communicated with backboard perforation 112 and cover plate perforation 122, to form at least one intercommunicating pore C.
Specifically, cover plate 120, towards the sun, can absorb solar energy effectively to allow solar cell 130.But, due to cover plate 120 upward, therefore the surface of cover plate 120 is also easily covered by dust dirt.In the present embodiment, when rainy, rainwater can rinse the surface of cover plate 120, and the dust dirt accumulated on cover plate 120 surface, with rainwater by running through the intercommunicating pore C of cover plate 120, encapsulation material 140 and backboard 110, and take away the surface of cover plate 120, the surface of cover plate 120 is no longer covered by dust dirt, the light transmittance of cover plate 120 can be kept by this, also make energy conversion effect of solar module 100 be kept.
Further illustrate, in the present embodiment, intercommunicating pore C does not run through solar cell 130 and welding thereof, and therefore the existence of intercommunicating pore C can't affect the running of solar cell 130.In addition, intercommunicating pore C also can not allow solar cell 130 be exposed to outside encapsulation material 140, allows aqueous vapor or oxygen invade and to affect the life-span of solar cell 130.
Please refer to Fig. 3, it illustrates the profile of the line segment 3 along Fig. 1.As shown in Figure 3, solar module 100 more comprises guard ring 170.The madial wall of at least coated intercommunicating pore C of guard ring 170, makes the crack that rainwater can not infiltrate cover plate 120 and encapsulate between material 140, or the crack between encapsulation material 140 and backboard 110.Therefore, solar module 100 can not affect its quality because rainwater infiltrates, and more can not therefore damage.
Go back to Fig. 1.As shown in Figure 1, solar module 100 more comprises support 150.Support 150 is in order to be installed on supporting surface 400, (Fig. 1 does not show support 150 supporting back board 110, please refer to Fig. 2 ~ Fig. 3), encapsulation material 140 (Fig. 1 does not show, please refer to Fig. 2 ~ Fig. 3), solar cell 130 and cover plate 120, make at least solar cell 130 can relative to supporting surface 400 gradient angle θ.
Cover plate 120 has centre of form GC.When solar cell 130 is relative to supporting surface 400 gradient angle θ, the height of intercommunicating pore C is lower than the height of centre of form GC.Thus, behind the surface of rain-out cover plate 120, rainwater can along the incline direction of cover plate 120, flows in the position towards intercommunicating pore C, to enable rainwater by intercommunicating pore C, and the dust dirt originally accumulated on cover plate 120 surface is taken away the surface of cover plate 120.
More particularly, solar module 100 more comprises frame 160.Frame 160 is around the edge of backboard 110, encapsulation material 140 and cover plate 120, and frame 160 has at least one downside side 162.When solar cell 130 is relative to supporting surface 400 gradient angle θ, the height of downside side 162 is lower than the height of centre of form GC.Have without cell area CFR1 near between a row solar cell 130 of downside side 162 and downside side 162.Intercommunicating pore C is positioned at this at least partly without cell area CFR1.
In the application of reality, between intercommunicating pore C and downside side 162, there is spacing G, and except the chance that suitable spacing G causes frame 160 to corrode except dust dirt can be reduced to gather near side (ns) frame 160 place, also the edge of cover plate 120 and backboard 110 can be made can not to produce breach because of intercommunicating pore C, and this also makes the structure of cover plate 120 and backboard 110 can keep complete.Based on considering of production technology precision, spacing G can be more than or equal to about 1mm, but the present invention is not as limit.
As shown in Figure 1, indivedual supports 150 of present embodiment can across the longer side 164 of frame 160, but the present invention is not as limit.As shown in Figure 4, in another execution mode of the present invention, indivedual support 150 also can across the shorter side 166 of frame 160.
Moreover because be subject to the impact of frame 160 shape, dust dirt easily accumulates in the corner of cover plate 120 surface adjoins downside side 162.Therefore, as Figure 1 and Figure 4, intercommunicating pore C can be positioned at the corner adjoining downside side 162 without cell area CFR1 at least partly, effectively to prevent gathering of dust dirt.Certainly, as shown in Figure 4, when not affecting solar module 100 structural strength, intercommunicating pore C can also equidistantly be arranged in the edge adjoining downside side 162 without cell area CFR1, to promote drainage efficiency.In the light of actual conditions, the quantity of intercommunicating pore C more can do suitable adjustment.
More particularly, in some embodiments, the material of frame 160 can be metal, and such as surface is through the aluminium alloy of anode process, but the present invention is not as limit.When the material of frame 160 is that surface is when the aluminium alloy of anode process, dust dirt easily corrodes the anode oxide film on aluminium alloy top layer after absorbing moisture content, make anode oxide film impaired, especially when containing sulfide in air, the damage of anode oxide film is by even more serious.Therefore, be positioned at the corner adjoining downside side 162 without cell area CFR1 at least partly by intercommunicating pore C, the dust dirt gathered in corner scope can be taken away by rainwater effectively.Therefore, the chance that the frame 160 of solar module 100, in nearly corner, corrosion occurs can effectively reduce.
As shown in Figure 4, intercommunicating pore C more can be positioned at adjoin downside side 162 without cell area CFR1 corner beyond position, to increase drainage efficiency.But for guaranteeing the structural strength of solar module 100, in without the intercommunicating pore C in cell area CFR1, its gross area can have certain proportionate relationship without the area of cell area CFR1 relatively.More particularly, according to the direction perpendicular to cover plate 120, have without cell area area without cell area CFR1, intercommunicating pore C then has intercommunicating pore area, in the present embodiment, the ratio that intercommunicating pore area accounts for without cell area area is about 3% ~ 50%, is more preferred from 5% ~ 20%.
Please refer to Fig. 5, it illustrates the vertical view according to the present invention's solar module 100 of an execution mode again.As shown in Figure 5, multiple intercommunicating pore C of present embodiment are except can be partly except circular hole, when not affecting solar module 100 structural strength, intercommunicating pore C can be also partly elongated hole (slot hole), but the present invention is not as limit.
Please refer to Fig. 6, it illustrates the stereogram of the solar module 100 according to the another execution mode of the present invention.As shown in Figure 6, in the present embodiment, the quantity of solar cell 130 is multiple, and two adjacent solar cells 130 define without cell area CFR2 therebetween, and intercommunicating pore C is positioned at least partly without cell area CFR2.In other words, intercommunicating pore C is between two adjacent solar cells 130.This takes away dust dirt except the drainage efficiency on cover plate 120 surface except increasing rainwater further, because intercommunicating pore C allows that air-flow passes through, therefore be distributed in without cell area CFR1 and without the intercommunicating pore C on cell area CFR2, also the blast that solar module 100 bears can effectively be reduced, and and then the wind loading rating of lifting solar module 100.Moreover air-flow can contribute to the cooling of solar cell 130 by intercommunicating pore C, make solar cell 130 can not be overheated, and its conversion efficiency be also maintained.
Should be appreciated that, although intercommunicating pore C illustrates as between two adjacent solar cells 130 by Fig. 6, this does not limit the present invention, and any position avoiding solar cell 130 and welding thereof, can arrange intercommunicating pore C.For example, in the execution mode that Fig. 7 illustrates, four adjacent solar cells 130 define without cell area CFR2 therebetween, and intercommunicating pore C is positioned at least partly without cell area CFR2.
In the present embodiment, cover plate 120 can be glass, and encapsulation material 140 can be ethene-vinyl acetate co-polymer latex (Ethylene Vinyl Acetate; EVA), backboard 110 and support 150 can be the aluminium alloy of surface through anode process, and guard ring 170 then can be silica gel.Should be appreciated that; above lifted backboard 110, cover plate 120 encapsulate material 140, support 150 is all only illustration with the material of guard ring 170; and be not used to limit the present invention; persond having ordinary knowledge in the technical field of the present invention; actual needs should be looked, suitably the material of selection backboard 110, cover plate 120, encapsulation material 140, support 150 and guard ring 170.
