Black solar photovoltaic module

Technical Field

The utility model relates to a solar energy technical field, in particular to black solar photovoltaic module.

Background

Solar energy is more and more concerned as a clean and renewable pollution-free new energy source, the application of the solar energy is more and more extensive, and the most important thing in the utilization of the solar energy is photovoltaic power generation at present. In a specific application, a plurality of solar cells are connected and encapsulated to form a photovoltaic module, and then the plurality of photovoltaic modules are connected in series and in parallel and combined with an inverter, a power distribution cabinet and other devices to form a photovoltaic system.

The photovoltaic module widely used at present mainly comprises toughened glass, EVA, a solar cell sheet packaged between two layers of EVA and a back plate. Photovoltaic modules can be classified into single crystal silicon modules and polycrystalline silicon modules according to the type of solar cell used. In recent years, the market share of the monocrystalline silicon component is gradually increased, which is mainly benefited by the fact that the monocrystalline silicon component has higher conversion efficiency and comprehensive performance, and the BOS cost of the photovoltaic power station is reduced. The single-glass single crystal assembly is mainly applied in the market at present, and can be divided into a white assembly and a black assembly according to different colors of a back plate and a frame. The black component has a completely black appearance, which provides a better aesthetic appearance when applied to a building rooftop.

Silver solder strips and silver bus strips are generally used for the existing black single crystal assembly, and the black assembly has chromatic aberration due to reflection of the silver solder strips and the silver bus strips to light, so that the effect of full black is difficult to achieve. The bus bar is shielded by using the black spacer in the prior art, but poor assembly due to the shift of the black spacer is easily caused in the lamination process. Therefore, how to improve the appearance consistency of the black photovoltaic module and ensure the quality and reliability of the module is a technical problem that needs to be solved by those skilled in the art at present.

Disclosure of Invention

To above problem, the utility model aims at providing a black solar PV modules through set up the black net layer in that the subassembly is inside, has realized sheltering from completely welding the area and converging the area for the subassembly presents the colour of complete blackness, has promoted the aesthetic property of subassembly.

The utility model provides a black solar photovoltaic module, includes lamination piece and frame, the lamination piece includes from last toughened glass layer, first encapsulated layer, solar wafer layer, second encapsulated layer and the backsheet layer down setting, solar wafer layer includes a plurality of battery cluster, and every battery cluster includes that a plurality of uses welds the solar wafer of taking the series connection, and a plurality of battery cluster uses converges and takes the series connection, be provided with black net layer between first encapsulated layer and the solar wafer layer.

The black grid layer comprises black transverse bars, black vertical bars and grids, the black transverse bars correspond to the confluence zone areas, the black vertical bars correspond to the welding zone areas, and the grids correspond to the solar cell areas and the gap areas thereof.

The width of the black transverse bar is larger than or equal to the width of the bus bar, and the width of the black vertical bar is equal to the width of the welding strip.

The black grid layer comprises a body layer and an adhesive layer, and the black transverse strips and the black vertical strips are respectively connected with the bus bars and the welding bars through the adhesive layer.

The thickness of the black grid layer is 0.1 mm-0.5 mm.

The solar cell is a monocrystalline silicon cell or a polycrystalline silicon cell, and the solar cell is a whole or sliced cell.

The solar cell is a P-type or N-type crystalline silicon cell.

The back plate layer and the frame are black.

The first encapsulation layer and the second encapsulation layer are one of ethylene-vinyl acetate copolymer, polyvinyl butyral, polyolefin, or silicone.

The utility model has the advantages of, through set up the black net layer between first encapsulated layer and solar wafer layer, the black horizontal bar and the black vertical retort of black net layer correspond respectively and weld the area and converge and take the region, therefore the black net layer has realized that the colour difference of subassembly inside and weld the area, converge and take the reflection of light to, have promoted the aesthetic property of subassembly by a wide margin.
