Embodiment Construction

[0017] A method for making a plastic-encapsulated solar photovoltaic module, wherein a first EVA material layer 2 is provided on a glass layer 1, a battery sheet layer 3 is provided on the first EVA material layer, and a second EVA material layer 4 is provided on the battery sheet layer, Set the back plate material layer 5 on the second EVA material layer; the above parts are laminated and formed into a laminate by a laminator, and then a plastic frame 6 that acts as a plastic seal is set around the laminate, and the plastic seal is performed by ultrasonic heat melting .

[0018] The battery slice layer is connected by a plurality of small battery slices 9 through welding strips 8 and bus strips 7 . The lamination temperature of the laminator is between 130°C and 150°C, the total lamination time is between 15min and 45min, and the pressure is between -60Kpa and 0Kpa. During ultrasonic thermal melting, the air pressure is 0.3-0.8Mpa, the welding time is 0.6-2s, and the holding...

Abstract

The invention discloses a manufacturing method of a plastic sealed solar photovoltaic assembly. The manufacturing method comprises the following steps: arranging a first EVA material layer on a glassy layer, arranging a cell layer on the first EVA material layer, arranging a second EVA material layer on the cell layer, and arranging a back plate material layer on the second EVA material layer, wherein all the parts are laminated and shaped into laminates by a laminating machine, and plastic frames with the plastic sealing function are arranged at the circumferences of the laminates and are subject to plastic sealing by ultrasonic hot melting. The invention thoroughly solves the problems that the conventional aluminum alloy frame is easy to oxidize and scratch, too much time is spent in waiting for the curing of silica gel and the like, raises the production efficiency, and lowers the cost.

Description

Technical field: [0001] The invention relates to a manufacturing method of a plastic-encapsulated solar photovoltaic module. Background technique: [0002] Currently known solar photovoltaic modules adopt the following structure: glass-EVA (ethylene-vinyl acetate copolymer)-single solar cell-EVA-back sheet material, and then assemble an aluminum alloy frame. [0003] Conventional solar photovoltaic modules using aluminum alloy frames have the following disadvantages: [0004] 1. The processing technology of the aluminum alloy frame is relatively cumbersome, which increases the cost; [0005] 2. The volume and weight of the aluminum alloy frame are large, which increases the transportation cost and installation difficulty; [0006] 3. It is easy to scratch during production, and the scratched place is easy to rust, and it is difficult to control the size and flatness of the corner seam; [0007] 4. The silica gel used in the installation process of the aluminum frame takes...
