leader in solar panel recycling technologies

StokkermillSolar is the division of Stokkermill Recycling Machinery dedicated to the development of advanced technological solutions for the treatment and recycling of end-of-life photovoltaic solar panels.The goal is clear: to concretely and sustainably address the environmental challenge posed by the disposal of decommissioned photovoltaic modules, ensuring the efficient recovery of the most valuable components, including glass, silicon powders and precious metals. Using a functionality-oriented engineering approach, we design and build reliable, automated, low-maintenance PV panel recycling facilities that can operate continuously 24/7 with low operating resources.

The Stokkermill Automatic Series
Solar3000

The recycling line for solar and photovoltaic modules allows for the recovery and reuse of materials found in discarded panels, such as silicon, glass, aluminum, plastic, and wiring. Thanks to an automated and advanced industrial process, each module is precisely dismantled, yielding reusable resources such as glass, silicon powder, aluminum, plastic, and copper. The system minimizes manual intervention and energy consumption (less than 1 kWh per module), ensuring high efficiency and reduced environmental impact. The technology allows for the treatment of polycrystalline, monocrystalline, and even non-standard sized modules, optimizing operating costs and improving the quality of recovered materials.

Efficient recovery, minimal impact.

How a Solar Panel is Made:

Material and weight

Delaminator Mill XRS

The Stokkermill XRS delaminator mill enables mechanical separation of layered materials, releasing the silicon/glass fraction trapped in the EVA layer. Using a controlled crushing process, the silicon is recovered in fine form along with a fine glass fraction and any precious metals.
Due to the specific design and use of special materials, wear and tear is extremely low, with minimal downtime and high operational continuity.

Recovered materials

From solar panels to new resources

Aluminum - Glass - Silicon - EVA - Copper

Aluminum

The Stokkermill system eliminates the need to remove the aluminum frame, speeding up processing. The aluminum output is ready for the furnace, clean, and compliant with End of Waste standards. This results in maximum value with minimum energy consumption.

High recyclability Reduced impact

Glass

The glass obtained from the treatment has different grain sizes and qualities. The larger fraction is very clean, while the finer fraction can still be used in the ceramics industry. Both fractions have a low iron content.

Main volume Consistent quality

Silicon

The finest fraction of the glass, containing silicon, traces of silver and other metals, is already used in various industrial sectors, but still represents an opportunity to explore for its value and recovery.

Technological value Fine fractions

EVA

The polymer fractions, back-sheet and EVA, free of glass and contaminants, are recovered at the end of the process and, thanks to their good calorific value, are used as alternative fuels.

Encapsulant Controlled separation

Copper

Copper is a strategic, valuable, and reusable metal. In solar panel recycling, Stokkermill leverages 20 years of experience and dedicated technologies, optimizing recovery and obtaining good quality material through an efficient process..

alluminum

The Stokkermilll recycling system does not require removal of the aluminum frame, drastically reducing panel processing time. The quality of the output materials is excellent.Aluminum, for example, will be oven-ready free of any pollutants and of the correct size, suitable for downstream metallurgical processing. Thus, maximumvalorization of the material and minimal energy impact during the final processing.

glass

The glass resulting from the treatment operations is of different grain size and quality. Larger size glass is clean, has a low iron content and is reused by the glass industry. A smaller size fraction still finds use in the glass or steel industry, where it can be used for the production of high quality silicon steels.

silicon

The thinnest fraction of glass will contain silicon, traces of silver and other metals. While it already finds wide application in a variety of industries, it is a fraction yet to be discovered in terms of value and recovery opportunities.

plastic

The polymeric back-sheet and EVA (Ethylene Vinyl Acetate) fractions, are recovered at the end of the process. They are fractions substantially free of glass and other pollutants and characterized by good calorific value such that they find applications as alternative fuels.

copper

During the solar panel recycling process, copper represents one of the strategic recoverable metals, mainly found in electrical conductors and, to a less significant extent, in the module's internal connections. Although it constitutes only about 1.2 percent of the total weight of a standard panel (about 12 kg out of a ton of treated panels), copper has high economic value and high potential for reuse in industry.
