Top 2 Solar Panel Management Solutions

With the rapid development of the solar energy industry, a large number of scrapped solar panels have gradually become a key issue in environmental management. How to efficiently and environmentally friendly recycle these waste components has become the focus of industry attention. At present, pyrolysis and mechanical methods are the two main solar panel recycling technologies, each with its own characteristics and suitable for different processing needs.

Pyrolysis method for solar panels recycling ——high temperature decomposition, recovery of pure materials

Pyrolysis is a method of decomposing organic materials from solar panels at high temperatures, allowing core materials such as glass, silicon wafers, and metals to be recovered. This method is particularly suitable for the efficient recovery of silicon and glass while reducing pollutant emissions.

What is the process of solar panels pyrolysis?

  • Pre-processing equipment (frame removal machine): You can disassemble the solar panels and remove the outer frame and junction box for subsequent processing.

  • Pyrolysis furnace: You need to place the treated panels in a high temperature environment of 400°C-600°C to decompose organic materials in oxygen-free or low-oxygen conditions.

  • Gas purification system: Treats volatile gases produced during the decomposition process to reduce harmful emissions.

  • Material sorting system (color sorter & vibrating screening machine): Separates recyclable glass, silicon wafers and metals (such as silver, aluminum, etc.).

The advantage of the pyrolysis method for solar panels recycling is that it can effectively recycle high-purity silicon materials, reduce dependence on new silicon materials, and reduce the contamination of the packaging layer to other recycled materials.

Mechanical method for solar panels disposal——physical crushing and sorting to improve recycling efficiency

The mechanical method is a way to recycle solar panel materials through mechanical crushing and separation. It is mainly suitable for large-scale recycling, is relatively simple to operate, and is suitable for different types of solar panels.

What equipment is suitable for photovoltaic panels mechanical disposal?

  • Crusher (double shafts shredder & hammer mill): Breaking solar panels into small pieces, releasing glass, silicon wafers and metal materials.

  • Vibration screener: Using a cylindrical vibration screener or a linear vibration screener to screen out silicon.

The advantage of the mechanical method for photovoltaic panels disposal is that the recycling process has low energy consumption. Then it is suitable for large-scale processing, can quickly disassemble various solar panels, and is suitable for processing complex electronic waste.
