A method for facilitating dismantling of a photovoltaic module includes steps of: obtaining, by an input module, product data of the photovoltaic module from a module information indicator provided on the photovoltaic module; retrieving, by a processor, a product identification code of the photovoltaic module by matching the product data against a database; generating, by an equipment controller, a control command based on the product identification code; and sending, by the equipment controller, the control command to a dismantling equipment to set equipment configuration parameters for the dismantling equipment to dismantle the photovoltaic module.

A frame includes a support structure made up of profiles for supporting photovoltaic panels, and which has two lateral sides; and at least one reinforcement element mounted in correspondence with the corresponding lateral side thereof for supporting additional loads to the weight of the cells. It further includes connection means for connecting to a torsion tube. In one exemplary embodiment the reinforcement element is a solid gusset from which the lateral sides are suspended, as well as the connection means include upper and lower clamps with a shape adapted to the torsion tube to avoid relative rotation, and which are tightened against the torsion tube by means of bolts which pass through the clamps and corresponding nuts, the upper clamp comprising lateral grooves to fit the reinforcement elements.
