Two-sided photovoltaic module of jumbo size solar energy

Technical Field

The utility model relates to a two-sided photovoltaic module of jumbo size solar energy belongs to MWT solar module processing technology field.

Background

In these years, photovoltaic technology is rapidly developed, technologies such as high-efficiency PERC, double-sided batteries and black silicon are put into mass production in the aspect of batteries, and N-type and heterojunction technologies also start to have certain market share; the technologies of double glass, half, multi-main grid, laminated tile and the like in the aspect of assembly also enter the large-scale industrialization stage. In addition to many technological breakthroughs (such as a multi-time crystal pulling technology and a diamond wire cutting technology) in the links of crystal pulling, slicing and the like, another phenomenon which is worthy of attention is that the size of the monocrystalline silicon wafer tends to increase, and based on the driving of an upstream silicon wafer, downstream enterprises design batteries and components corresponding to the large silicon wafer, and the batteries are expanded from 5BB lines to 6BB lines. It is therefore desirable to make photovoltaic modules that can be perfectly matched to large size 6BB cells. As for the traditional assembly, a single-sided assembly is usually used, the improvement of the power generation capacity is limited, and the reduction of the power consumption cost is limited.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: problem and not enough to exist among the prior art, the utility model provides a can perfectly match photovoltaic module of jumbo size 6BB battery.

The technical scheme is as follows: the utility model provides a jumbo size solar energy double-sided photovoltaic module, includes the battery layer, is equipped with the EVA layer in the battery layer outside, is equipped with high printing opacity top layer in the EVA layer outside the edge of lamellar structure is equipped with the frame and is used for fixed overall structure, the battery layer includes a plurality of six main grid batteries, welds with the solder strip between each six main grid batteries in proper order, high printing opacity top layer is upper and lower each layer glass or one deck glass, and another layer is the backplate, can realize two-sided electricity generation.

The back plate of the high-light-transmission surface layer is a high-molecular transparent back plate.
