Solar Panel Recycling Plant

— Turnkey Solar Panel Recycling Plant

The Solar Panel Recycling Plant is designed specifically for discarded crystalline silicon photovoltaic modules (scrap, damaged, defective, and retired panels). It can automatically remove aluminum frames and junction boxes, peel off tempered glass, and then crush, grind, and sort the remaining laminates into high-purity silicon powder, copper, silver-containing materials, glass, and plastics, with an overall material recycling rate of over 95%. Available in two proven process routes — the physical crushing & sorting line and the pyrolysis recycling line — the equipment is fully automated, energy-efficient and environmentally safe, and turns solar panel waste into a profitable, compliant recycling business.

Product Overview

The world installed more solar capacity in the past decade than in all previous decades combined. As the first large-scale PV plants pass their 25–30 year design life, and as extreme weather, transport damage and warranty returns accelerate early retirement, the industry is entering its first true decommissioning wave. According to the International Renewable Energy Agency (IRENA), cumulative global PV panel waste will reach roughly 8 million tonnes by 2030 and could exceed 78 million tonnes by 2050. The U.S. EPA estimates that the recoverable raw materials in end-of-life solar panels will be worth about US$450 million by 2030 — equivalent to the raw materials for some 60 million new panels — and more than US$15 billion by 2050.

Yet most retired panels are still landfilled today. A crystalline-silicon module is a tightly bonded laminate of glass, EVA encapsulant, silicon cells, metal ribbons and an aluminum frame, and the strong EVA adhesive makes conventional dismantling difficult. This is precisely the problem YuSai Machinery’s solar panel recycling equipment was built to solve.

Our solution covers two complementary routes. The physical crushing & sorting line uses mechanical dismantling, crushing, grinding and dry separation — no heat, no chemicals — and is the economical standard choice for single-glass (monofacial) panels. The pyrolysis line cracks the EVA/backsheet in an oxygen-free tunnel furnace, enabling clean separation of double-glass (bifacial) panels and whole silicon wafers for maximum silver recovery. Both routes are backed by our in-house silver stripping and precious metal refining equipment, a natural extension of YuSai’s core refining technology — so the whole value chain, from scrap panel to saleable silver and silicon, comes from a single supplier.

Recycling Value Analysis

A crystalline-silicon PV module consists of roughly 70–75% tempered glass, about 10% aluminum frame, around 5% silicon cells, and under 1% silver paste and copper ribbons by weight, with EVA encapsulant, backsheet and plastics making up the remainder. Yet the small fraction of precious metals carries a disproportionately high share of the economic value — and every component becomes a saleable product:

Tempered glass (~70–75%) — recovered as clean glass cullet: a bulk-volume material with stable off-take in glass manufacturing.
Aluminum frame (~8–10%) — recovered as aluminum scrap in a mature, liquid scrap market: the fastest direct payback item.
Silicon cells (~4–5%) — recovered as silicon powder or whole wafers that feed back into industry; purification adds further value.
Silver paste & copper ribbons (<1%) — recovered as silver and copper: the highest value per gram and the key profit driver of the line.
EVA, backsheet & plastics (~5–8%) — recovered as plastic powder for use as secondary plastic feedstock.

Why The Economics Work:

95%+ material recovery rate — almost every component becomes a saleable product instead of landfill cost.
Separation rate up to 99% — air classification plus high-voltage electrostatic separation delivers clean silicon powder, clean plastics and concentrated metals that command premium prices.
Silver & copper premium — through the pyrolysis route and silver stripping / precious metal refining, high-purity silver is recovered from the cell busbars; despite its tiny weight share, silver can account for a significant share of revenue per tonne of panels.
Regulatory tailwind — the EU WEEE Directive, expanding U.S. state laws and Asia-Pacific EPR schemes increasingly mandate or incentivize PV recycling, securing feedstock and justifying recycling fees.
Clear payback logic — aluminum frames and silver are the fastest payback items; overall payback depends on local scrap prices, feedstock volume and recycling fees. Contact us for an ROI estimate tailored to your market.

Applicable Materials

Monocrystalline (mono-Si) and polycrystalline (poly-Si) panels
Single-glass (monofacial) modules — standard physical line
Double-glass / bifacial modules — pyrolysis line (or dedicated double-glass pre-treatment)
End-of-life panels from decommissioned plants and rooftops
Damaged, broken, defective, warranty-return and warehouse-return panels
Framed or frameless panels; with or without junction boxes (pre-treatment machines remove them first)
Peripheral components: aluminum frames, junction boxes, copper ribbons, busbars

Note: Thin-film modules (CdTe) contain cadmium-telluride and require a dedicated recycling process; our standard crystalline-silicon lines are not intended for them. Please inform us of your material mix so we can configure the correct line.

Product Structure (Main Equipment)

1. Pre-Treatment Station (both lines)

Solar Panel Junction Box Removing Machine

Detaches the junction box (and attached cables) from the back of the panel. Removing it first prevents plastic and copper from contaminating the downstream glass and silicon fractions, and keeps the feed to the crusher uniform.

Solar Panel Aluminum Frame Removing Machine

Automatically removes the aluminum frame from all four edges of the module. Available in semi-auto and fully-auto versions: the semi-auto model clamps and pulls the frame off after quick manual positioning, while the fully-auto version senses the panel size and completes the whole removal cycle without manual handling. The frame comes off cleanly and intact, so it can be sold directly as aluminum scrap with no further processing.

Solar Panel Glass Removing Machine

Robot-Arm Auto Loading(Optional)

An industrial robot arm automatically lifts each panel from the pallet and places it onto the feeding conveyor in the correct orientation, replacing manual panel handling. It keeps the line running at full rhythm, reduces labor requirements, and eliminates the risk of injury from lifting heavy, glass-edged panels by hand.

2. Solar Panel Crushing & Sorting System (physical line)

The solar panel crushing & sorting system is the core of the physical recycling line. After the frame, junction box and most of the glass have been removed in the pre-treatment station, the remaining EVA-bonded laminate enters this system and is progressively reduced — from strips to particles to fine powder — then separated by density and conductivity into clean, saleable fractions. The whole process runs under negative pressure, with no water and no chemicals, making it economical, safe and environmentally friendly. From the laminate it produces clean silicon powder, copper powder and plastic powder, delivering the value that makes PV panel recycling profitable.

Double Shaft Shredder

Tears the pre-treated laminate into strips (roughly 1–2 cm) between two counter-rotating shafts with interlocking blades. The low-speed, high-torque design handles the tough EVA-bonded laminate reliably without material wrapping or jamming.

Hammer Crusher

The second size-reduction stage: reduces the shredded strips into small, uniform particles ready for fine grinding. The grid screen controls the discharge size, giving high throughput and consistent particle size.

Fine Grinder (with return system)

Mills the material into powder under negative pressure. An integrated classification/return system automatically sends oversized particles back for re-grinding until they reach the target size, ensuring consistent powder quality with zero material waste.

Air Classifier (Airflow Separator)

Separates lightweight plastics (EVA)from the heavier silicon and metal powder in an air stream, using the density difference between the fractions. With a separation rate up to 99%, the light fraction exits as clean plastic powder while the heavy fraction continues to electrostatic separation.

High-Voltage Electrostatic Separator

Separates metals from plastics by conductivity in a high-voltage field. Multi-stage separation minimizes non-ferrous metal loss (especially copper), maximizing the metal value recovered from each tonne of panels.

3. Solar Panel Pyrolysis Sorting System (pyrolysis line)

The solar panel pyrolysis sorting system is the core of the pyrolysis recycling line, designed for double-glass (bifacial) panels and cell-level recovery. After the frame and junction box are removed, the panels enter the oxygen-free tunnel furnace, where the EVA encapsulant and backsheet are thermally decomposed so the glass, silicon cells and copper ribbons are fully released from the laminate without being crushed. The released materials are then separated into whole silicon wafers, copper wire and clean glass, and the silver is stripped from the wafers to recover its full value. Because the cells come out intact rather than ground to powder, this route delivers the highest-quality silicon and the most complete silver recovery.

Solar Panel Tunnel Pyrolysis Furnace

Oxygen-free, temperature-controlled thermal cracking of the EVA encapsulant and backsheet. Modules travel continuously through the tunnel furnace on a conveyor; intelligent temperature control decomposes the polymer layers while keeping the glass and silicon cells intact. The exhaust gas from the process is treated before discharge, meeting environmental standards.

Solar panel vacuum pyrolysis furnace

A standalone single machine for small-scale or pilot pyrolysis recycling. Panels are placed in a sealed vacuum chamber where the EVA encapsulant and backsheet decompose under low pressure and controlled temperature, allowing complete layer separation at lower temperatures with minimal thermal stress on the glass and silicon cells. Fully automated vacuum and temperature control, with an integrated exhaust-gas treatment system — an ideal entry-level choice when a full tunnel line is not yet justified, and it can be expanded into a complete line later.

Solar Panel Post-pyrolysis Sorting System

Separates the cracked mixture into copper wire, silicon wafers and glass using vibration and air separation. The result is clean, ready-to-sell fractions that need no further downstream cleaning.

Silver stripping machine

Strips silver from the silicon cells/wafers after pyrolysis, as part of YuSai’s precious metal refining series. It recovers silver at high purity for maximum value, completing the loop from scrap panel to saleable precious metal.

4. Common Auxiliary Systems

Pulse dust collector

High filtration efficiency; the whole line runs under negative pressure to prevent dust overflow and keep the workshop clean and compliant. A pulse-jet cleaning system automatically blows accumulated dust off the filter bags at set intervals, so filtration efficiency is maintained without stopping production; the collected dust is discharged in a closed container for centralized disposal.

Exhaust gas spray tower (wet scrubber)

Treats the flue gas from the pyrolysis furnace. The hot gas enters the tower and passes through fine water spray, where harmful components are absorbed and particles are captured; the purified gas is discharged while the scrubbing water is recirculated and treated in a closed loop, keeping emissions within environmental limits.

PLC control cabinet

One-button start, uniform feeding and coordinated operation of every station. The PLC monitors motor loads, conveyor speeds and safety interlocks in real time; a fault alarm points directly to the affected station, and processing parameters can be tuned for different panel types. Optional remote access lets our engineers provide online support whenever needed.

Belt conveyors & feed hoppers

Continuous, balanced material flow between stations. Conveyor speed is matched to the processing rate to prevent overfeeding or material buildup, while the feed hoppers buffer the input so the line keeps running smoothly even when feeding is intermittent.

Water cooling system (grinding chamber)

Controls grinding temperature to protect output quality and reduces noise. Circulating water carries heat away from the grinding chamber, preventing thermal damage to the material and extending the service life of the screens and grinding parts; the water is recycled in a closed loop with minimal consumption.

A: A complete line recovers aluminum frames, clean glass, silicon powder, copper, plastics (EVA/backsheet) and silver, with an overall material recovery rate above 95%.

Q2: What is the difference between the physical line and the pyrolysis line? Which do I need?
A: The physical line (crushing, grinding, dry sorting) is the economical standard choice for single-glass (monofacial) panels — no heat, no chemicals. The pyrolysis line (tunnel furnace) is recommended for double-glass / bifacial panels and when you want whole silicon wafers and maximum silver recovery. Many customers start with the physical line and add pyrolysis later; we recommend based on your actual panels.

Q3: What capacity should I choose? How much space does it need?
A: Standard models cover small-scale pilot to industrial capacity. Tell us your daily tonnage and site size and we will provide a layout drawing and capacity recommendation.

Q4: How long is production and delivery?
A: Production typically takes 15–30 days after order confirmation; sea freight to most ports takes 20–40 days depending on destination. Progress videos and shipping documents are provided throughout.

Q5: What is the price? What is the payback period?
A: Price depends on configuration (process route, capacity, optional silver refining). We quote transparently after you share your material and capacity. Aluminum frames and silver are the fastest payback items; contact us for an ROI estimate for your market.

Q6: Can I test with my own material before buying?
A: Yes. Send waste panel samples; we run them on the actual line, record video and report recovery and output quality before shipment.
