Abstract: A method for insulating an aluminum backboard of a photovoltaic module comprises the following steps: shearing the aluminum backboard such that the dimensions of the aluminum backboard are 4-5 mm smaller those of the glass; forming a square aperture at the position of the electrode lead of the aluminum backboard; insulating the square aperture by cushioning a small insulating material or wrapping the edges with an insulation film when arraying and laying the modules; laminating and trimming the superimposed module components; wrapping the trimmed laminated piece around the edge with the 0.5-1 mm insulation tape; finally, framing up the laminated piece by using a frame filled with silica gel, and installing the terminal box. The invention is convenient to operate and low in investment and has a wide application prospect.
