Abstract
The utility model provides a thin and light type solar photovoltaic module, comprising a transparent PET film, an upper EVA, a solar cell string, a middle EVA, an epoxy resin board, a lower EVA and a piece of waterproof cloth, which are stacked in order. According to the utility model, the waterproof cloth is added and pressed on the back side of the epoxy resin board of a given PET solar photovoltaic module, thereby reducing the contact between the EVAs and the air and slowing down the aging of the EVAs. Solar cells and the epoxy resin board are sandwiched between the uppermost transparent PET film and the downmost waterproof cloth, thereby greatly reducing the possibility of the transparent PET film being delaminated from the epoxy resin board. Meanwhile, the varied appearance of the waterproof cloth makes the whole product more beautiful.
Description
Technical field
The utility model relates to field of photovoltaic power generation, particularly a kind of light and thin type solar photovoltaic assembly.
Background technology
Along with the use of solar energy generation technology in the compact applications product, the outer charger of domestic solar for example, solar module lightweight, that outward appearance good, the scale of construction is thin becomes a kind of new demand.Chinese patent application number is 200610038976.3, open day is to announce a kind of utilization on August 30th, 2006 to drip the mode that glue encapsulates solar components, its technology is full-fledged, the solar panels that utilize the method to make, appearance looks elegant, weight is lighter, the mobility constraints of glue but weak point is, during solar panels more than making 5W, be difficult to allow glue cover on the solar panels uniformly, and if add excessive glue for glue can be covered comprehensively, then when heating, form the glue that overflows around the substrate easily, and cooled excessive glue is difficult to be removed, and causes presentation quality poor.Therefore, this kind packaging technology can only be made less solar components, is generally the solar components less than 5W.
Chinese patent application number is 200810242562.1, and open day is to announce a kind of technique of utilizing thin polymer film to carry out the solar components encapsulation on June 3rd, 2009.It is characterized in that utilizing the TPT backboard in the epoxy resin board replacement simple glass assembly, utilize the TPT plate to replace the toughened glass that has now in the assembly, thereby reduce its weight.Yet the back side of the ultrathin solar components of this explained hereafter is epoxy resin board or circuit board, and it is poor that outward appearance is felt.And because epoxy resin board is hard, and upper strata EVA is soft, and when cutting edge after lamination is finished, operate miss very easily causes EVA delamination from the epoxy resin board, thereby exposes the intermediate solar cell sheet.And EVA directly is exposed on end face in the air, very easily causes the aging of whole solar components.
The utility model content
The technical problems to be solved in the utility model is: for the back side that solves light and thin type solar photovoltaic assembly of the prior art directly is epoxy plate and appearance poor, EVA is exposed to and accelerates the aging problem of this solar panels in the air, the utility model provides a kind of light and thin type solar photovoltaic assembly, one deck waterproof cloth has pressurizeed at the back side of epoxy resin board, can reduce contacting of EVA and air, slow down the aging of EVA.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of light and thin type solar photovoltaic assembly, comprise the clear PET film, upper strata EVA, solar cell string, the middle level EVA that stack gradually, epoxy resin board, the EVA of lower floor and waterproof cloth, described solar cell string has positive wire and negative wire.
Embodiment one, and the clear PET film surface has been drawn opening, and described positive wire and negative wire are drawn out to outside the light and thin type solar photovoltaic assembly from the opening of clear PET film surface.
Embodiment two, and draw on the waterproof cloth surface opening, and described positive wire and negative wire are drawn out to outside the light and thin type solar photovoltaic assembly from the opening on waterproof cloth surface.
Embodiment three, and described positive wire and negative wire are drawn out to outside the light and thin type solar photovoltaic assembly from the side along solar cell string plane.
The beneficial effects of the utility model are, the utility model one deck waterproof cloth that pressurizeed at the back side of the epoxy resin board of known PET solar photovoltaic assembly can reduce contacting of EVA and air, slows down the aging of EVA.Clear PET film and the undermost waterproof cloth of the superiors are clipped in the middle cell piece and epoxy resin board, greatly reduce the probability of clear PET film delamination from the epoxy resin board, and the multifarious outward appearance of waterproof cloth can increase the aesthetics of integral product simultaneously.
