6 FAQs about [Grinding the back plate of photovoltaic panels]

Can selective grinding remove resin from glass in silicon-based PV panels?

Selective grinding during the initial stage of grinding is effective for removing resin from glass in silicon-based PV panels. Many previous studies on the separation of glass from resin have investigated the applicability of chemical processes, but we achieved separation by brief physical processes.

Can a PV panel be used as a raw material?

The selectivity was high at a high rotation speed and during the initial stage of grinding. We found that 97% of the glass in a PV panel can be recovered with less than 1% C contamination for particles smaller than 5.6 mm by grinding at 2500 rpm for 5 min. The resulting glass particles are suitable for use as raw material for glass fiber.

Can shredded EOL PV panels be recycled?

Volume 72, pages 2615–2623, (2020) One of the technical challenges with the recovery of valuable materials from end-of-life (EOL) photovoltaic (PV) modules for recycling is the liberation and separation of the materials. We present a potential method to liberate and separate shredded EOL PV panels for the recovery of Si wafer particles.

How is selective grinding used to remove resin from glass particles?

Selective grinding was used to remove resin from glass particles as a secondary grinding process for the recycling of glass from silicon-based PV panels.

What is the recycling process for silicon-based PV panels?

In this review article, the complete recycling process is systematically summarized into two main sections: disassembly and delamination treatment for silicon-based PV panels, involving physical, thermal, and chemical treatment, and the retrieval of valuable metals (silicon, silver, copper, tin, etc.).

How to separate glass and back sheet solar panels?

In the first stage, 20 pulses of around 110 kV separate glass and back sheet solar panels, followed by sieving and dense medium. In the second separation method, the glass layer was crushed to a size fraction of 45–850 μm using 250 pulses at a rate of 90 kV. After separation, there was a 30% increment in silver concentration.
