SunPower Maxeon 3 400W: recycling and end-of-life
Reviewed by the eCycling Central editorial team on April 2026
The SunPower Maxeon 3 400W (SunPower / Maxeon Solar, 2019-2024) is a 400W monocrystalline IBC solar panel weighing 19 kg. This guide covers material composition, take-back routes, and end-of-life economics.
Material composition
A typical SunPower Maxeon 3 400W contains:
- Aluminium frame: 2.9 kg - LME spot ~$2.40/kg = $6.96
- Tempered glass: 12 kg - low value but recyclable
- Silicon cells: 620g
- Silver paste (cell metallisation): 5.8g - silver spot ~$0.85/g = $4.93
- Copper backsheet wiring: ~50-100g
- EVA encapsulant + backsheet polymer: mixed-grade plastics
Take-back via SunPower / Maxeon Solar
SunPower / Maxeon Solar sustainability and recycling programme
SunPower / Maxeon Solar participates in regional take-back schemes (PV CYCLE in EU, SEIA in US). Check the link above for current options in your country.
Recycling cost
Typical end-of-life recycling cost: 15-30.
Recoverable material value: $9-17.
Net cost varies by jurisdiction and processor. EU panels generally cost less to recycle due to mandatory PV-CYCLE infrastructure; US panels often cost more without a federal take-back programme.
Where to recycle
- EU/UK: PV CYCLE registered processor (https://pvcycle.org)
- US: SEIA Recycling Network member, First Solar (CdTe panels), We Recycle Solar
- Asia-Pacific: PV CYCLE Asia Pacific affiliated processors
- Australia: Solar Energy Industries Association recycling partners
Why panels need controlled disposal
Solar panels contain lead solder (older panels), cadmium telluride (CdTe panels like First Solar), and trace amounts of arsenic. Direct landfill disposal is banned in:
- All EU member states (WEEE Directive Annex IV)
- Washington, California, and 7 other US states
- Australia (NSW from 2025, others to follow)
Improper disposal carries fines of $1,000-25,000 per panel under WEEE-equivalent regulations.

Frequently Asked Questions
Can I throw a SunPower Maxeon 3 400W in regular waste?
No. The SunPower Maxeon 3 400W contains lead solder, trace arsenic, and (for CdTe panels) cadmium. Direct landfill is banned in all EU member states, Washington, California, and 7 other US states, and Australia (NSW from 2025). Use the manufacturer take-back programme or a PV CYCLE registered processor.
What is a SunPower Maxeon 3 400W worth in scrap?
Typical recoverable material value is $9-17. The aluminium frame (2.9 kg) and silver content (5.8g) make up most of the value.
Does SunPower / Maxeon Solar offer a take-back programme?
Yes. See [SunPower / Maxeon Solar sustainability page](https://maxeon.com/sustainability). SunPower / Maxeon Solar participates in regional schemes (PV CYCLE in EU, SEIA in US).
