The continuous development of solar energy industry has effectively alleviated the serious environmental pollution and energy crisis. The number of residential solar systems installed has also increased dramatically, which means that we are less and less dependent on non-renewable sources energy. However, there is an important question behind the good news: Every solar power system has a fixed life cycle, what should we do once the solar panels run out of life?


With this question in mind, many experts put forward the idea of recycling solar panels. Next, we'll explain how this idea can be realized.



How long will the Solar Panels Last?

The life expectancy of a normal solar panel is 30 years.  It is estimated that power capacity will be reduced by about 20% during the use of photovoltaic panels. However, it is found that even if the panel has been used for 25 years, the power efficiency has only decreased 10% in actual use. Therefore, the life of solar panels is much longer than expected.

2. How to Deal with Solar Panels?

A good solar panel is not only for the short-term use but also to provide reliable energy solutions for the future. The general solar panels have to be destroyed after its service life has expired. But now there are solar companies recycling solar panels to reprocess them. Solar power manufacturers must comply with legally recycling standards to ensure that those obsolete solar panels do not have a negative impact on the environment. 


The solar panels produced by Luxen Solar Company achieve the sustainable development through the reprocess of solar materials. We cooperate with professional e-waste recyclers to realize the recycling of solar panels from two aspects: material health and social environmental protection.

3. Recycling Process of different Solar Panels 

(1) Silicon Photovoltaic Panel

After the silicon photovoltaic panels are disassembled, the glass can be reused directly and those metals will reassemble the outer frame of the solar panels. There are some other small parts will be processed at high temperatures to ensure that each component will not be wasted.

(2) Thin-film Solar Panel

Compared with silicon solar panels, the machining process of thin-film solar panels is more complex. They are put into the hammer-mill to attrite all the particles. The rest is mainly a mixture of solid and liquid materials. In order to separate the liquid, we need to screw the solid part into a container. Then the purity of the liquid is greatly improved after precipitation and dehydration. The purified material can be made into different types of semiconductor materials and the fixed solid can be washed into the required material.


The recycling of solar photovoltaic panels not only creates employment opportunities for the society, but also generates huge energy through the reuse of materials. As the price of solar energy continues to fall, more and more enterprises choose to invest in solar power systems. As a result, there will be more economic opportunities for solar cell recycling
