Recycling of photovoltaic modules

We are happy to advise you on choosing the right disposal method for your PV modules. To make it easier to classify the modules, we provide a form for photovoltaic modules. We also keep track of all legal requirements, such as extended producer responsibility, at all times.

Manufacturers, importers, and distributors must take back PV modules that they placed on the market after June 30, 2014, from end users free of charge. If the modules are being replaced with new ones, those placed on the market before June 2014 must also be taken back free of charge.

Undamaged and functional modules can be tested and, if necessary, reused. Modules that are no longer functional or are damaged are recycled properly.

The recycling process involves several steps: First, the modules are dismantled to remove the aluminum frames and cables. This allows raw materials to be recovered from the connection cables and aluminum from the frames.

The next step is the mechanical shredding of the remaining module. The resulting materials, in particular glass, silicon, and precious metals, are then separated by machine and processed for further use. The raw materials obtained in this way flow back into the production cycle. Saubermacher already achieves a recycling rate of over 85% today – an important step towards resource conservation and a sustainable circular economy.

Silicon-based modules are the most commonly used technology in photovoltaic systems. They consist of several layers of different materials that efficiently convert sunlight into electrical energy. A single module weighs around 18 to 22 kilograms and consists mainly of glass, silicon, and aluminum. Some of these materials can be reused in the recycling process.

Modern photovoltaic modules have an average service life of 25 to 30 years. Many systems remain functional beyond this period, although their performance declines slightly over time.

Photovoltaic modules should be disposed of when they are defective, their performance has significantly deteriorated, or they have reached the end of their service life. As a rule, the service life is around 25 to 30 years.

In many countries, manufacturers are legally obliged to organize the return and disposal of photovoltaic modules. Depending on the region, consumers can hand in their old modules at municipal waste collection centers or recycling centers. Saubermacher also takes care of the professional recycling of PV modules.

For private individuals, the disposal of photovoltaic modules is usually free of charge, especially for normal household quantities. Commercial disposal can incur costs that vary depending on the quantity and provider.

Saubermacher provides a form for the disposal order. This form asks for all the necessary information about the photovoltaic modules . Since the environmentally friendly recovery of materials from PV modules involves a high level of technical effort, a corresponding cost contribution may be charged for this service. We inform our customers transparently in advance.

There are non-hazardous photovoltaic modules (silicon-based) and hazardous modules (containing heavy metals such as cadmium).

End-of-life photovoltaic modules can be returned to all Saubermacher locations. To ensure smooth processing, the modules should be delivered as clean and stacked as possible. Neither the connection cable nor the frame need to be removed. Even broken glass surfaces do not affect acceptance or further processing.

Improper disposal of photovoltaic modules can lead to the release of pollutants such as lead and cadmium, which are harmful to the environment. It is therefore important to dispose of the modules properly.
