Description

A kind of waterproof photovoltaic tiles structure
Technical field
The present invention relates to a kind of waterproof photovoltaic tiles structures, belong to solar energy manufacturing technology field.
Background technique
As the continuous drop sheet and popularization, photovoltaic products of photovoltaic technology will gradually benefit masses.Previous family roof light Volt system is to install common photovoltaic module using the not busy complementary space on roof, however, due to photovoltaic module itself and installing steel Weight is larger, often causes to bear to building roof, while there is also construction complexity, building for traditional rooftop photovoltaic systems Consumption of materials is big, space utilization rate is low and influences the disadvantages of beautiful.
Compared to common photovoltaic module, photovoltaic tiles then have and can make full use of roof area, be able to satisfy architectural appearance The advantages that individual demand.Meanwhile photovoltaic tiles can replace conventional roof tile to use tempering glass without additionally being installed Photovoltaic tiles made of the high-strength materials such as glass are packaged not will cause the load-bearing burden on roof not only, instead due to its own The remote ultra-traditional tile of intensity is capable of forming firmer building roof.Meanwhile the sun to roof according to shine will effective quilt Photovoltaic tiles are converted into electric energy and reduce roofing temperature, are conducive to the energy utilization rate for improving building.
However, some photovoltaic tiles with roof waterproof function need the ranked and stacked pile that misplaces, such as Fig. 1 d and 1e.In order to make Rainwater can be flowed down along inclined tiled surface without leak, and influence the terminal box for protruding from the photovoltaic tiles back side not Closely stacking between upper and lower tile, these photovoltaic tiles are typically required for being hidden more than the region of half by upper layer tile Gear.In this patent, in photovoltaic tiles, region having solar battery sheet, can be used for photovoltaic power generation is referred to as photovoltaic tiles " effective coverage ", and blocked by upper layer tile, without solar battery sheet, the region that can not be generated electricity be referred to as " inactive area ". Although not needing cell piece in the inactive area of photovoltaic tiles, remaining encapsulating material generally requires to keep one with effective coverage It causes, will lead to cost waste in this way, make photovoltaic tiles price be difficult to decline, be unfavorable for marketing.
Summary of the invention
The technical problem to be solved by the present invention is to providing one kind can be by the area of the inactive area of reduction photovoltaic tiles And material cost, to realize the waterproof photovoltaic tiles structure for reducing photovoltaic tiles price.
In order to solve the above technical problems, the technical solution adopted by the present invention are as follows:
A kind of waterproof photovoltaic tiles structure, including several photovoltaic tiles units, the photovoltaic tiles unit dislocation stacking Stack, the photovoltaic tiles unit includes connected effective coverage and inactive area, the photovoltaic tiles unit it is described effectively Region transverse direction close-packed arrays are layered, and the effective coverage of photovoltaic tiles unit described in upper layer is located at photovoltaic tiles list described in lower layer The upper surface of the inactive area of member, the effective coverage is placed with solar battery sheet, and the back side of the effective coverage is connected with Terminal box, inactive area described in lower layer form the void area passed through for terminal box described in upper layer.
The effective coverage and inactive area use identical encapsulating material, and the encapsulating material includes from top to bottom successively Connected front photovoltaic glass, multilayer laminate and back side photovoltaic glass offers cavity, the cavity shape in the inactive area At the void area.
The width of the inactive area is less than the width of the effective coverage, shape between two adjacent inactive areas At the void area.
The shape of the inactive area includes rectangle, triangle or trapezoidal.
The effective coverage uses encapsulating material, and the encapsulating material includes the front photovoltaic glass being sequentially connected from top to bottom Glass, multilayer laminate and back side photovoltaic glass are connected after the completion of the effective coverage encapsulation with the inactive area.
The inactive area is using identical or partial encapsulation material integrally connected forms with effective coverage.
The back side of the inactive area is provided with the fixation device being connected with tile bracket.
The terminal box is Split type connecting box.
The material of the inactive area includes glass or plastics.
It is connected between the inactive area and the effective coverage by bonding way.
Beneficial effects of the present invention: photovoltaic tiles of the present invention use the hollow out passed through for upper layer terminal box or other figures Structure is effectively reduced the inactive area that cannot be generated electricity.Material cost is not only greatly saved in this, since terminal box moves down While saving part metals welding, moreover it is possible to play the role of reducing tile series resistance, improve photovoltaic tiles generating efficiency.
Further, by the type of encapsulating material in the inactive area of reduction photovoltaic tiles, and by rationally designing Material cost can be further reduced by cutting out.Simultaneously as entire tile area is smaller, it is possible to reduce the layer occupied in production process Pressure surface product, improves product volume production efficiency, reduces the energy consumption in production process.
