Easy-Disassembly Module
Solving Recycling at the Source

"Design is the recycling plan for the future"

Traditional solar modules use EVA (ethylene vinyl acetate) encapsulation. When heated, EVA releases gases that build pressure and crush the cell sheets — making it impossible to extract intact silicon wafers during recycling. Only crushing is possible, which drastically reduces material purity and residual value.

RePV EVA easy-disassembly modules use a dual-layer encapsulation structure. When heated, a protective buffer layer forms between the two layers, effectively absorbing the pressure from gas release and preventing cell sheet damage. At end-of-life, simply apply heat to delaminate completely — cell sheets, glass, and silver paste are each recovered at maximum purity.

Why Easy-Disassemble

After Recovery,
The Numbers Speak

For the same 1MW project, the recovery value difference at end-of-life is up to 6×. The critical difference lies in whether the module encapsulation allows high-purity disassembly.

Technical Details

In-Depth Technical Explanation

Traditional solar modules use EVA (ethylene vinyl acetate) as encapsulation material. The problem with EVA is: when heated to soften it, the material releases gases. These gases build pressure in the enclosed space and crack or even pulverize the cell sheets.

This means once the recycling process begins, cell sheets cannot be extracted intact — only crushing and grinding are possible, producing silicon that is a contaminated mix of glass, plastic, and metal fragments with extremely low purity, sold at very low prices or sent directly to landfill.

  • Silicon recovery purity: Traditional crushing yields only sub-3N silicon fragments (price NT$0.02/kg)
  • Glass recovery: Crushed glass contaminated with plastic and solder ribbon has almost no market value
  • Silver recovery: Mixed as silver powder in residue, quality difficult to control

RePV EVA easy-disassembly encapsulation uses a dual-layer structural design. When heated, a protective buffer layer forms between the two layers, absorbing the pressure from gas release and effectively preventing cell sheet damage.

This design makes the end-of-life disassembly process extremely simple: just apply appropriate heat and the module cleanly delaminate — glass is removed intact, cell sheets remain whole, and silver paste circuits are undamaged.

  • Power efficiency: Equivalent to standard modules, with no impact on normal power generation performance
  • Lifespan: Passes standard certification testing, same service life as traditional modules
  • Disassembly method: Heat to soften → complete delamination → each material extracted separately

After easy-disassembly modules reach end-of-life, RePV equipment can recover intact silicon wafers. When these recycled silicon wafers are remanufactured into new modules, the carbon footprint is far lower than the traditional path of re-smelting from quartz sand.

CO₂e / wafer

Solar panels remanufactured from recycled silicon wafers reduce the overall carbon footprint from the traditional 304.6 kg GHG to 122.1 kg — a reduction of over 60%.

The easy-disassembly module is the starting point of RePV's full-cycle ecosystem. The high-purity materials recovered after end-of-life can not only be remanufactured into low-carbon solar panels, but also enter high-value lateral applications:

  • Silicon wafers (7N purity): Return to solar cell manufacturing processes, or enter semiconductor feedstock
  • High-purity glass: Recycled into designer quartz slabs (e.g. Mikado Quartz series), entering the premium building materials market
  • High-purity silver: Recovered as silver compounds or high-purity silver, entering electronics, medical, and other high-value applications
  • Aluminum frame: 100% recovered, can be made into computer chassis and other industrial products

Every project using RePV easy-disassembly modules is an entry point into this circular economy.
