Abstract
A kind of high-efficiency solar-powered photovoltaic assembly, comprise toughened glass, an EVA, battery strings, the 2nd EVA and backboard, described toughened glass, an EVA, battery strings, the 2nd EVA and backboard form according to order lamination from top to down, the both positive and negative polarity of described battery strings is connected by welding, on the toughened glass of described welding top, be provided with reflective groove, the utility model by arranging reflective groove on the toughened glass above welding, thereby the luminous energy of welding top is reflected on the cell piece in extinction region, thereby has increased the utilization ratio of luminous energy.
Description
Technical field
The utility model relates to a kind of solar components, is specifically related to a kind of photovoltaic module that can make full use of luminous energy increase light conversion ratio.
Background technology
At present, due to sustainability and the nonstaining property feature of luminous energy, solar energy is commonly used, corresponding solar module is also for consumers in general accept, but existing solar module, due to structural defect, the life-span that causes making full use of luminous energy, particularly photovoltaic module is limited, if the structure of photovoltaic module is not carried out to appropriate design, increase so undoubtedly use cost, caused the waste in resource, caused the generating efficiency of electric power station system low.
Summary of the invention
For addressing the aforementioned drawbacks, the utility model carries out appropriate design by the structure at solar module, and between battery component, cause cannot carry out structural design again in extinction region, luminous energy in cannot extinction region is dredged to the solar battery sheet in extinction region, thereby realize effective utilization of luminous energy, increase light conversion ratio, thereby increased benefit, reduced cost.
For achieving the above object, the utility model is by the following technical solutions: a kind of high-efficiency solar-powered photovoltaic assembly, comprise toughened glass, an EVA, battery strings, the 2nd EVA and backboard, described toughened glass, an EVA, battery strings, the 2nd EVA and backboard form according to order lamination from top to down, the both positive and negative polarity of described battery strings is connected by welding, on the toughened glass of described welding top, is provided with reflective groove.
Further, described reflective groove is frosted Baltimore groove.
Further, described backboard is white epoxy resin plate.
Further, described EVA is ethylene-vinyl acetate copolymer, is commonly called as EVA colloidal sol.
Compared with prior art, the utility model is by reflective groove is set on the toughened glass above welding, thereby the luminous energy of welding top is reflected on the cell piece in extinction region, thereby increased the utilization ratio of luminous energy.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of high-efficiency solar-powered photovoltaic modular construction of Fig. 1 schematic diagram.
In figure, 1 toughened glass, 2 the one EVA, 3 battery strings, 4 the 2nd EVA, 5 backboards, 6 reflective grooves, 7 weldings.
Embodiment
A kind of high-efficiency solar-powered photovoltaic assembly, comprise 1 toughened glass, 2 the one EVA, 3 battery strings, 4 the 2nd EVA and 5 backboards, described 1 toughened glass, 2 the one EVA, 3 battery strings, 4 the 2nd EVA and 5 backboards form according to order lamination from top to down, the both positive and negative polarity of 3 described battery strings is by 7 welding series connection, on 1 toughened glass of 7 described welding tops, be provided with 6 reflective grooves, 6 described reflective grooves are frosted Baltimore groove, 5 described backboards are white epoxy resin plate, described EVA is ethylene-vinyl acetate copolymer, is commonly called as EVA colloidal sol.
Obviously, above-mentioned execution mode is preferred embodiments of the present utility model, and any simple modifications on this basis all belongs to protection range of the present utility model.
