Solar panel recycling plant, delamination model
Technical Features, Economic Performance and Operating Context
For operators handling limited processing volumes and a homogeneous, pre-sorted feedstock, Stokkermill Solar offers the Solar Delamination system: a low-temperature thermal-mechanical delamination solution (<90°C) with a throughput capacity of 50–70 photovoltaic modules per hour (equivalent to approximately 1–1.5 t/h). The system is designed for operations where incoming material has already been de-framed and sorted. It represents an entry-level solution within the mechanical photovoltaic recycling chain, with the inherent limitations associated with this type of process.
Solar Panel Recycling Process – Delamination Line
Phase 1 – Aluminium Recovery:
The photovoltaic module is fed into the plant after prior frame removal. The aluminium frame is recovered upstream and directed to dedicated recycling streams.
Phase 2 – Low-Temperature Thermal Delamination (<90°C) and Coarse Glass Recovery:
The PV module is processed through the HMS Delaminator. Controlled heat below 90°C softens the EVA encapsulant sufficiently to enable mechanical separation of the laminated layers. The coarse glass fraction is recovered as the first output stream and can be supplied to the glass manufacturing or ceramics industries.
Phase 3 – Size Reduction and Particle Classification:
The residual material undergoes further comminution and ballistic separation. This stage prepares the material stream for downstream recovery processes, ensuring consistent particle size distribution before entering the secondary delamination stage.
Phase 4 – Secondary XRS Delamination and Fine Glass Recovery:
The XRS Delaminator mechanically separates the remaining EVA fraction, releasing fine glass particles and silicon powder. The fine glass fraction is recovered as a second glass output stream, suitable for use in the ceramics industry or as recycled aggregate.
Phase 5 – EVA Refining and Silicon Fraction Recovery:
A ballistic separator classifies the remaining material into homogeneous fractions with controlled particle size. The EVA fraction is separated and recovered, while the silicon concentrate powder is extracted as a distinct output stream, ready for reintroduction into industrial recycling and raw material recovery markets.
