A deassembling system of a photovoltaic panel for enabling salvage of original materials of the photovoltaic panel, the photovoltaic panel comprising: a photovoltaic cell, comprising siliceous material, copper and silver; a glass layer for protection of the photovoltaic cell; a first layer of plastic material for protecting the photovoltaic cell; a second layer of plastic material for protecting the photovoltaic cell; the photovoltaic cell being arranged between the first layer of plastic material and the second layer of plastic material; the system being characterised in that it comprises: a cutting machine comprising: a counter-blade; a mobile blade for cooperating with the counter-blade; the blade and the counter-blade being conformed so as to cut a photovoltaic panel, forming a plurality of cut pieces; an oscillating hammer mill comprising: a chamber receiving the cut pieces; a plurality of facing teeth which are arranged in a circular direction, which delimit the chamber and which are solidly constrained to a frame of the oscillating hammer mill; a drive shaft; a plurality of hammers which are arranged in the chamber, which are drawn in rotation by the drive shaft and which are freely rotatable with respect to the drive shaft about rotation axes that are arranged along a portion of circumference which is concentric to the axis of the drive shaft; the hammers and the teeth being conformed and arranged to break up the cut pieces, forming fragments of glass and other broken pieces that are larger than the glass fragments; first sifting means, which receive the fragments of glass and pieces; the first sifting means comprising a sifting wall provided with a plurality of meshes; the meshes being dimensioned in such a way as to enable the glass fragments to cross the meshes so as to enable salvaging thereof and so as to enable the pieces to remain on the sifting wall; a fixed hammer mill comprising: a chamber receiving the sifted pieces from the first sifting means; a facing plurality of teeth which are arranged in a circular direction, which delimit the chamber and which are solidly constrained to the frame of the fixed hammer mill; an activating shaft; a plurality of hammers that are arranged in the chamber, which are drawn in rotation by the activating shaft and which are solidly constrained to the activating shaft; the hammers and the teeth being conformed and arranged so as to break down the pieces, forming fragments of plastic material and powder material; the powder material being of smaller size than the fragments of plastic material and comprising siliceous materials, plastic materials, copper and silver; second sifting means, which receive the fragments of plastic material and the powder material; the second sifting means comprising a sifting wall provided with a plurality of meshes; the meshes being sized so as to enable the powder material to cross the meshes and so as to enable the fragments of plastic material to remain on the sifting wall in order to enable salvaging thereof. a cutting machine comprising: a counter-blade;
