The two routes
02
Route A — dismantle first
The module is deframed, the junction box is removed and the glass is separated before any size reduction. Each fraction leaves as its own stream.
What you get. Clean aluminium that a remelt operation will take without argument. Glass collected before it is mixed with laminate. Copper kept out of the cullet. A cell fraction that a downstream recovery buyer can accept.
What it costs. More stations, more handling, more floor area and more labour. The line is longer and the capital is higher. Through-put per operator is lower than a reduction-first plant.
When it is right. When your revenue depends on selling clean aluminium and glass, and when you have a downstream outlet that requires sorted fractions.
03
Route B — size reduction first
The module goes to size reduction with the frame still on, and everything is separated afterwards from a mixed granulate.
What you get. A much simpler plant: fewer stations, less floor area, lower labour and a smaller capital requirement. For some outlets that is a perfectly good business.
What it costs. The aluminium comes out contaminated with glass and laminate, and the glass comes out carrying metal fragments. Both streams are downgraded from the moment the frame enters the mill, and there is no economic way to un-mix them afterwards.
When it is right. When your downstream outlet is a mixed-fraction processor that accepts and re-sorts granulate, and when footprint or capital is the binding constraint rather than output quality.

Side by side
| Dismantle first | Reduce first | |
|---|---|---|
| Aluminium quality | Clean frame sections, directly remeltable | Contaminated with glass and laminate |
| Glass quality | Collected before mixing with laminate | Broken together with encapsulant and metal |
| Copper | Removed with the junction box | Distributed through the granulate |
| Stations and footprint | More stations, larger footprint | Fewer stations, compact |
| Labour per tonne | Higher | Lower |
| Capital | Higher | Lower |
| Output to downstream buyer | Sorted fractions | Mixed granulate requiring further separation |
| Best fit | Clean-stream revenue, specification-driven buyers | Mixed-fraction outlet, footprint or capital constrained |

How to decide
- 01
Ask your downstream buyer first
Will they accept a mixed granulate, or do they require sorted fractions? This single answer usually settles the route.
- 02
Price the difference in the output
Clean aluminium and clean glass attract different prices from contaminated streams — often a large enough difference to repay the extra stations.
- 03
Check the footprint you really have
Route A needs more floor area and more material movement space. If the hall cannot take it, the decision is made for you.
- 04
Consider the hybrid
Many plants dismantle the frame and junction box, then send the laminate to a reduction and separation stage. That is Route A's front end with Route B's downstream, and it is often the practical compromise.
- 05
Do not decide on machine price
The price difference between the routes is small compared with the difference in what the output is worth.
Which outlet do you have?
Tell us who buys your output and what they will accept. That is the input that decides which route your project should take.
FAQ
Questions
Is shredding solar panels without deframing ever acceptable?
Yes, where the outlet accepts a mixed granulate and where the plant is constrained on footprint or capital. What it is not is a route that produces clean aluminium and clean glass, because both streams are contaminated from the moment the frame enters the mill.
Which route gives a higher recovery rate?
Recovery rate is the wrong measure on its own, because a plant can recover a high proportion of mass into low-value contaminated streams. The useful question is what each output fraction is worth and whether a buyer will accept it.
Can a reduction-first plant be converted later?
The downstream separation equipment usually carries over, but the front end has to be added ahead of it, which means building space, conveying and utilities that the original layout may not have allowed for. That is an argument for deciding the route before the layout rather than after.
What is the hybrid arrangement?
Deframe and remove the junction box, then send the remaining laminate to size reduction and separation. It captures the two highest-value streams up front and still allows a compact downstream stage — which is why it is the most common arrangement we quote.
Send us the module mix and the through-put
Tell us what arrives at your gate and what has to leave. The engineering team replies with the station configuration, the scope boundary and the information still missing before drawings start.
- Modules — framed single-glass, double-glass, frameless, thin film, mixed
- Condition — intact, or a meaningful share damaged or bent
- Through-put — modules per hour or t/h, and your shift pattern
- Output — which fractions you sell or store, and to what specification
