Solar photovoltaic module recycling equipment

The present invention relates to a resource recycling device, and more particularly to a solar photovoltaic module recycling device.

Electric energy has become an indispensable source of energy in modern life. At present, there are two main types of power generation for stable power supply: thermal power generation and nuclear power generation. However, the carbon dioxide generated by thermal power generation will aggravate the greenhouse effect and bring about serious climate change, nuclear waste generated by nuclear power generation and nuclear disasters that may occur. Accidents are even more unbearable for humans and the environment. Clean and pollution-free solar power generation is seen as a glimpse of the dilemma of maintaining the environment and using energy.

In order to reduce the proportion of power generation in thermal power generation and nuclear power generation, it is bound to increase the production and erection of solar photovoltaic modules year by year. With the goal of increasing solar power generation to 8700 MW year by year, it is estimated that the total amount of waste caused by solar photovoltaic module damage will reach nearly one million tons by 2050. Although solar power generation does not impose a burden on the environment during power generation, if the damaged solar photovoltaic modules are not properly disposed, a large amount of waste will still have an adverse effect on the environment.

In general, a solar photovoltaic module includes a solar cell capable of generating electricity, and two encapsulating films disposed on opposite sides of the solar cell unit for bonding the solar cell unit to a glass and a back plate.
