METHOD AND APPARATUS FOR DETACHING GLASS FORM A MONO- OR POLYCRYSTALLINE SILICON-BASED PHOTOVOLTAIC PANEL

摘要

Process for separating glass from a photovoltaic panel laminate, the laminate comprising an encapsulating layer (3) of partly cross-linked ethylene vinyl acetate, EVA, and containing photovoltaic cells of mono- or polycrystalline metallic silicon, a front plate (5) of glass and a back sheet (7) bonded to the encapsulating layer on opposite surfaces thereof. The process comprises the stages of:
heating the laminate (1) by infrared heaters (R1, R2) to raise the EVA to a working temperature of between 70 and 150°C in order to cause it to soften; and
removing the glass from the encapsulating layer (3) heated to the working temperature.
