Solar energy photovoltaic building element
The utility model relates to a kind of solar power generation product, and particularly a kind of energy substitutes the cheap solar energy photovoltaic building element of traditional roofing.
Along with the quick growth of global economy, the construction that various countries also accelerate to infrastructure, but also serious day by day to the destruction of nature simultaneously.The discharge capacity of the greenhouse gas of high buildings and large mansions accounts for more than 30% of the whole world, is one of reason that directly causes global warming, and using green energy resource to replace traditional energy is one of important means that reduces greenhouse gas emission.At present, the photovoltaic product wins initial success with combining of building, various photovoltaic building materials have appearred, but its product can not be real alternative traditional construction material, and building bearing had higher requirement, and that can not really realize and build be integrated, and it is attractive in appearance that influence is built, and its higher price is not accepted by most of people yet.
Summary of the invention
The utility model is in order to overcome traditional roofing tile and the solar module inferior position in architecture-integral uses, a kind of both had waterproof, heat insulation, fire prevention have been invented, have function such as generating and a kind of solar energy photovoltaic building element of outward appearance and building one integrated mass again.This solar energy photovoltaic building element adopts the staggered floor construction design, can be directly installed on the roofing, need not extra mounting system, overall structure is light, simple, suitable, and cost is loaded onto photovoltaic module relatively and is reduced more than 30% on traditional roofing, is particularly suitable for the large public building roof and uses.
The technical solution adopted in the utility model is:
A kind of solar energy photovoltaic building element, by substrate, solar cell device, encapsulating material, cover plate assembles, solar cell device is arranged on the encapsulating material on the substrate by variety of way, place the encapsulating material encapsulation on the solar cell device, and just draw, the negative pole wiring, lamination encapsulates after covering cover plate, before the lamination sealing-in, make between substrate and the cover plate and vertically staggering into step by anchor clamps, form corresponding staggered floor construction, thereby guarantee that photovoltaic building element is in vertical sealing-in, laterally fix by mounting groove on the beam, mounting groove with between photovoltaic building element adopt screw to be connected and seal viscose glue and seal with industry.The vertical both sides of photovoltaic building element directly overlap by the staggered floor step, and are bonding with fluid sealant, guarantee ne-leakage; The both lateral sides of photovoltaic building element is directly installed in the mounting groove on the roof, and mounting groove directly is fixed on the beam of building.
A kind of solar energy photovoltaic building element is mainly assembled by substrate, solar cell device, encapsulating material, cover plate, encapsulating material select for use have transparent, sealing, materials with function such as moistureproof, stable, heatproof, uvioresistant; Substrate can use multiple material, as toughened glass, corrosion resistant plate, aluminium alloy etc.; Solar cell device comprises all solar cells that can generate electricity such as various crystal, amorphous, film, cover plate adopts transparent material, have characteristics such as waterproof, sun-proof, windproof, fire prevention as toughened glass, transparent resin etc., and stable performance, life-span are long, cheap.The substrate of photovoltaic building element and cover plate seal by high performance industrial viscose glue at the formation step that vertically staggers, and laterally are directly installed in the mounting groove on the roof.
The beneficial effects of the utility model are: function such as a kind of solar energy photovoltaic building element can be heat insulation, waterproof, fire prevention, generating, and need not mounting system, simple in structure being suitable for, can with the building perfect the combination, facility quick for installation, with low cost, very easily apply the incorporate of solar energy and building.

The utility model will be further described in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of solar energy photovoltaic building element is assembled by cover plate 1, encapsulating material plastic of poly vinyl acetate EVA 2, solar cell device 3, substrate 4, solar cell device is arranged on the encapsulating material on the substrate, place encapsulating material on the solar cell device, draw the positive and negative electrode wiring, cover cover plate 1, guarantee substrate and the cover plate formation step that staggers by anchor clamps before sealing-in, lamination encapsulates again.Substrate 4 is selected toughened glass for use, and cover plate 1 is also selected toughened glass for use.The connected mode of solar cell device connects into the loop with bypass diode after the solar cell device series connection as shown in Figure 5.
A kind of solar energy photovoltaic building element is made according to the following steps:
1, substrate and cover plate are prepared: blanking, cleaning;
2, welding: solar cell device, positive pole and negative wire welding;
3, combination: with toughened glass substrate 4 upper berth encapsulating material EVA2,, encapsulate integrated core component spreading plastic of poly vinyl acetate EVA2, cover toughened glass cover plate 1 again with solar battery sheet 3 marshalling on EVA2;
4, encapsulation: by the anchor clamps location toughened glass cover plate 1 and toughened glass substrate 4 are staggered the 3rd semi-finished product finished of step and form a step, carry out the lamination encapsulation again.
5, detect: carry out outward appearance, mechanical performance and electrical property and detect;
The both sides up and down of photovoltaic building element are designed to step, so that at vertical sealing-in such as Fig. 2, the connection aspect the left and right sides is adopted the direct sealing-in of mounting groove as shown in Figure 3, overall structure such as Fig. 4 of back photovoltaic roof are installed.
