Description
Technical field
The utility model belongs to solar photovoltaic assembly technical field, is specifically related to the solar photovoltaic battery component of a kind of backboard toughened glass protection.
Background technology
Above mentioned solar photovoltaic battery component refers to the i.e. frameless solar photovoltaic battery component without installation frame.Along with mankind's awareness of saving energy and environmental protection consciousness and to the continuous enhancing of non-renewable natural energy resources as the protective awareness of oil, coal, natural gas and even ocean ice etc.; more and more be subject to thinking highly of of the whole mankind as inexhaustible cleaning new energy and solar energy, thus the application surface of solar photovoltaic generation system is constantly expanded.Solar photovoltaic battery component is the pith in complete solar energy photovoltaic system, and its function utilizes photovoltaic effect and solar energy is converted into electric energy.
As is known in the industry, the life-span of solar photovoltaic battery component and the material of its use closely related.In the structural system of solar photovoltaic battery component, material is that the useful life of the component of plastics is the shortest often.Backboard is the pith in solar photovoltaic battery component, but due to the material of backboard be plastics, thus when use one after date easily because self aging, distortion, cracking etc. cause whole solar photovoltaic battery component to be difficult to the requirement in the satisfied use expected design life-span of 25 years.In addition, the deflation that sleet load, variation of ambient temperature, wind load etc. can cause mechanical pressure to solar photovoltaic battery component too, coefficient of thermal expansion and contraction causes and stretching, finally cause the fatigue of materials of solar photovoltaic battery component, except backboard damages, the electrical connection bar of the cell connector be made up of copper wire and electrical connection mechanism also can produce fracture situation because repeatedly turning from side to side, cause open circuit or the energy output decay of solar panel, even cause short circuit.
The technical information about solar photovoltaic battery component is no lack of in disclosed Chinese patent literature, as CN102064218B(solar module structure), CN102136504B(solar module and application thereof), CN202120950U(mono-kind is without frame BIPV solar module), CN102544162B(solar module) and CN203325929U(mono-kind with H type structure without frame solar battery component), etc.
" a kind of flexible crystal silicon solar batteries assembly " that " a kind of solar module " and CN103928553A typically as patent of invention publication number CN104638041A recommendation provide; at the process dorsulum being put to essence use, these two patent application schemes, owing to not having the direct or indirect safeguard measure to backboard, thus easily occur that the applicant is in above mentioned technical problem.
" a kind of double-sided glass curtain solar module " that " solar module of alternative roof sheet tile and preparation method thereof " that patent of invention publication number CN101447521A introduces and publication No. CN102270684A disclose, these two patents make backboard avoid and contacting external air owing to have employed toughened glass, have positive effect for the useful life extending backboard.
And then as is known in the industry, solar photovoltaic battery component is generally sandwich construction, (CN101447521A is black polyvinyl fluoride composite membrane to be such as followed successively by top layer from top to bottom, CN102270684A is ordinary copper glass), EVA layer, solar cell layer (also claim silicon wafer plate), EVA layer and backsheet layer (CN101447521A is the low iron toughened glass of high strength, and CN102270684A is super white patterned toughened glass).Prolongation under arms particularly along with Years Of Service in process, add the impact of natural cause, generally can produce following two all do not wish to occur but invariably cannot will inevitably occur the technical problem of (being only degree difference): one, due to subtle ground generating layer break joint gap, thus extraneous humid air, fog, rainwater etc. can attack solar cell layer, and the light transmission causing backsheet layer goes down, reduce photoelectric conversion efficiency; Its two, the rectangular body of the geometry in view of solar photovoltaic assembly or square, thus four bights become fragile place, and aforesaid delamination also often starts from bight.
Utility model patent Authorization Notice No. CN202797048U discloses to be had " corner protector for without frame solar battery component ", this corner protector comprises partially enclosed inner space and for the upper surface that limits inner space and lower surface and two side surfaces, wherein, upper surface and lower surface have rectangular leg-of-mutton shape when observing from surface, and two side surfaces are at a right angle, inner space have towards the side at right angle for the close-fitting opening of corner without frame solar battery component.This patent formula objectively can embody the technique effect that the 0008th section, its specification is recorded, and namely can make up aforesaid second technical problem.But there is following shortcoming: one is according to described in the 0018th section, specification, select and make corner protector with weather-proof elastomer silicone, at 170 DEG C, using compression molding instrument to carry out casting-forging method, (right-angle side length is 35.3 ㎜, two side surface length are 5.4 ㎜), it can thus be appreciated that, this corner protector is owing to adopting rubber, and thus weatherability is relatively fragile, and manufacturing process trouble; Two is because plane upper surface and plane lower surface are arcwall face, is thus essentially tangent contact with the contact of solar photovoltaic assembly, again because the material of corner fittings is rubber, is thus difficult to ensure the effect be positioned on solar photovoltaic assembly enduringly; Three is because the global shape of corner protector is L-shaped, thus be difficult to make the intersection of two right-angle sides of corner fittings and the edges and corners of solar photovoltaic battery component keep desirable fiting effect, thus overall co-ordination and the sealing effectiveness of whole corner protector and solar photovoltaic battery component can be affected to a certain extent; Four is that thus elastic force is relatively weak due to structural reason, thus can not reach industry expected degree to the clamping force of solar photovoltaic assembly or clamping force, even can there is the anxiety got loose.
For above-mentioned prior art, be necessary to be improved, the applicant has done positive and useful design for this reason, and define technical scheme described below and carried out analogue test in the test center of the applicant taking under secrecy provision, result proves practicable.
