HOW SOLAR PANEL RECYCLING DONE?
Solar panel Recycling process depends upon the material used in manufacturing of solar panel. So,solar panel recycling process can be classified mainly two categories: silicon based solar panel recycling and non-silicon based solar panel recycling. Recycling process can be helpful in reducing price of solar panel and save environment from hazards materials which used in solar panel manufacturing. According one estimation up to 2025 solar panel recycling industry will across 15 billion dollar mark.
SILICON BASED SOLAR PANEL RECYCLING
the recycling process starts with removing frames from solar panels. second step is crushing solar panels into small grain sized particles then after different fractions are separated. It is possible to recover more than 85% of the total solar panel weight without considering framing. this type of recycling is done using the technology which is used to recycle glasses from buildings and automotive industry. recycle silicon can be used for manufacturing solar cell once again and same for lamination material.
NON SILICON BASED SOLAR PANEL RECYCLING
for recycling non silicon solar panel require specific technology of recycling considering the materials used in manufacturing of solar panel. Different chemical processes used for retrieving the materials in pure form or re useable form from recycling material. most of steps are followed in this recycling are same as silicon based recycling type but chemical processes and parameters such like temperature , pressure are different .This recycling process is designed to recover up to 90% of the glass and 95% of the semiconductor materials contained.
Some private companies and non-profit organizations are currently engaged in take-back and recycling operations for end-of-life modules.Government and many non-profit organizations are trying to bring manufacturers, recyclers and researchers together to look at the future of PV module recycling. In upcoming ten years solar panel recycling industry will grow with more than 25% growth.
