Glass may be recovered from a used solar module through heating and the application of stress (such as mechanical stress). One or more of ⋅junction box removal, ⋅cable removal, and/or ⋅deframing may result in a used solar module comprising glass adhered to a laminate including polymer and a photovoltaic (PV) material such as crystalline silicon. Heat can be applied via conduction, convection and/or radiation to achieve removal of glass. Applied radiation of specific wavelengths may be absorbed by material(s) of interest (e.g., polymer encapsulant) but not by others (e.g., the glass). Following and/or concurrent with the heating, the module may be subject to stress to allow the glass to detach (e.g., in the form of cullets) from the laminate. One approach may be to bend the glass-laminate combination. This bending effectively creates enough stress for the cullets to detach and separate (e.g., fall under the force of gravity).
