How to profit from the surplus value of used photovoltaic panels?

2024-10-22

Photovoltaic panel recycling and processing equipment After the photovoltaic modules are retired, they go through five processing links: first, the modules are disassembled and transported to the processing agency; second, they are disassembled and the backplane and wires are removed; third, the modules are broken and the tempered glass on the outside is removed; fourth, pyrolysis is performed; and fifth, the valuable metals and silicon materials in the modules are taken out.

The recovery and reuse rates of solar-grade silicon are very low, so there is still a lot of room for improvement. Recycling silicon in photovoltaics is important for reducing carbon emissions, and research and development should be stepped up now so that the technology can be used for recycling and reuse markets when a large number of modules begin to be scrapped. Recycling and reusing solar-grade silicon can also reduce the impact of photovoltaic panels on the environment, as this material accounts for about half of the carbon footprint of the equipment. Technology to recover solar-grade silicon from used solar panels can change the module recycling market. If the recycling process can provide solar-grade silicon instead of metallurgical-grade silicon, the value of silicon recovery may be higher.

Photovoltaic panel crusher equipment recycles silicon materials. The residual value of waste photovoltaic panels is completed by photovoltaic panel processing equipment, glass is completed by glass removal machine, frame processing is completed by frame disassembly equipment, and the crushing body is composed of an integral knife box, a high-strength spindle, and imported alloy steel knives. It has large shear force, high stability, good shredding effect, and long service life… It can quickly achieve the goal of crushing and recycling high-value components in waste photovoltaic panels. The entire processing process uses mechanical crushing, without wastewater, waste gas and dust generation, which can achieve harmless processing, high recovery rate, low resource consumption, low environmental pollution, and high economic benefits.

Photovoltaic panels after coarse crushing, fine crushing, sorting and other processes will be sent to different industries for reuse. For example, broken glass will be sent to the glass manufacturing industry, aluminum frames will be sent to aluminum refineries, waste plastics can be used as fuel in cement plants, silicon can be reused in the precious metal industry, and cables and connectors can be sold in the form of copper beads.
