UK solar panel waste will reach 50,000 tonnes annually by 2030, according to DESNZ modelling
Solar panels installed during the 2010s boom are now reaching the end of their working life. The Department for Energy Security and Net Zero (DESNZ) projects that cumulative solar panel waste in the UK could reach 50,000 tonnes per year by 2030 (DESNZ solar PV waste modelling, 2026).
Solar panel disposal costs £50–£200 per tonne in 2026. Under WEEE regulations, installers must offer free take-back when replacing panels, and homeowners cannot send them to landfill. Plan disposal early to avoid fines of up to £5,000.
- Solar panels are classed as WEEE, cannot go to landfill.
- Installers must offer free take-back when replacing panels.
- UK recycling capacity is limited to fewer than 10 facilities.
- Self-disposal without an authorised carrier risks £5,000 fines.
- Panels are recycled via thermal treatment at 400–500°C.

The average solar panel lifespan is 25–30 years, meaning panels fitted in the early 2010s are now entering disposal pipelines. Current UK recycling capacity is limited, with fewer than 10 dedicated solar panel recycling facilities operating as of 2026 (Environment Agency waste permits register, 2026).
This section sets the scale of the problem and why homeowners need to plan for disposal now.
What the law requires when disposing of solar panels in the UK
Solar panels are classified as Waste Electrical and Electronic Equipment (WEEE) under UK regulations, specifically category 4 (large equipment) (GOV.UK WEEE regulations guidance, 2026). WEEE stands for Waste Electrical and Electronic Equipment, a legal framework that governs how electronic waste must be collected and treated.
Producers and importers must finance take-back and recycling through a registered compliance scheme. Homeowners cannot legally send panels to general waste or landfill. Installers who fitted your system are legally required to offer free take-back when replacing or decommissioning panels (Environment Agency WEEE producer responsibility guidance, 2026).
Homeowners who self-dispose without using an authorised waste carrier risk fines of up to £5,000 under the Environmental Protection Act 1990 (Environmental Protection Act 1990).
How solar panel recycling actually works in 2026
Panels are first dismantled: aluminium frames and junction boxes are removed mechanically, and glass is separated from the silicon cells. The silicon cells are processed through thermal treatment at 400–500°C to burn off the EVA encapsulant, recovering up to 95% of semiconductor-grade silicon (PV Cycle UK technical factsheet, 2026). EVA encapsulant is the plastic layer that seals the silicon cells inside the panel.
Glass accounts for 75–80% of panel weight and is crushed into aggregate for construction or new panel production. Silver, copper, and aluminium are extracted using hydrometallurgical processes, with recovery rates exceeding 90% for precious metals (DESNZ circular economy for PV materials report, 2025).
This section explains the process without oversimplifying — the reader learns what happens to their old panels.

Eligibility and how to verify an authorised solar panel recycler
Only waste carriers registered with the Environment Agency (England), Natural Resources Wales, SEPA (Scotland), or NIEA (Northern Ireland) can legally collect and recycle solar panels. Check the public register online (GOV.UK waste carrier registration search, 2026).
Look for recyclers certified under the WEEE compliance scheme. Membership in PV Cycle UK or REPIC indicates proper end-of-life processing (PV Cycle UK member list, 2026). REPIC is one of the largest WEEE compliance schemes in the UK.
Installers who are MCS-certified and TrustMark-registered must offer free take-back under their producer responsibility obligations. Ask for written confirmation before agreeing to new installation. Verify that the recycler provides a waste transfer note or consignment note — without this, the homeowner remains legally responsible for the waste (Environment Agency guidance on waste duty of care, 2026). how to find an MCS certified solar installer
When free take-back applies and when you must pay
Under WEEE regulations, if you are replacing panels with a new system from the same installer, they must take back the old panels at no cost to you (GOV.UK WEEE producer responsibility guidance, 2026).
If you are decommissioning panels without replacement, the original installer or their compliance scheme must still offer free take-back — but you may need to arrange transport to their collection point. If your original installer has ceased trading or you cannot identify them, you must find a registered waste carrier and pay the recycling fee — typically £8–£15 per panel for collection.
If panels are damaged (cracked glass, exposed wiring), disposal costs rise because special handling is required. Some recyclers charge double for damaged panels (PV Cycle UK damaged panel handling policy, 2026).
What happens if you sell your house with old solar panels
When selling a property with solar panels, the seller must disclose the age and condition of the system in the Property Information Form (TA6). Failing to mention end-of-life panels could lead to legal claims for misrepresentation (Law Society TA6 guidance, 2026).
Buyers may request a disposal plan or proof of a recycling contract as a condition of sale. Estate agents report this becoming more common since 2025 (NAEA Propertymark member survey, 2026).
If the panels are leased (for example, through a rent-a-roof scheme), the lease contract typically places disposal responsibility on the leasing company. Check your agreement before planning disposal. solar panel lease agreements explained
Frequently Asked Questions
No. Solar panels are classed as WEEE under UK regulations and cannot be sent to general waste or landfill. The Environment Agency states that homeowners must use an authorised waste carrier or arrange take-back through the installer.
Disposal costs range from £50 to £200 per tonne depending on the facility and transport. Some local councils offer free WEEE collection for small quantities, but bulk disposal typically incurs a fee, according to the Environment Agency waste permits register.
Under WEEE regulations, producers and importers must finance take-back through a registered compliance scheme. Installers who fitted your system are legally required to offer free take-back when replacing or decommissioning panels, as confirmed by the Environment Agency guidance.
Panels are dismantled: aluminium frames and junction boxes are removed, glass is separated, and silicon cells undergo thermal treatment at 400–500°C to burn off the EVA encapsulant. Recovered materials include glass, aluminium, and silicon for reuse, as detailed by MCS recycling standards.
Yes, under WEEE regulations, solar panel recycling is mandatory. Homeowners cannot legally dispose of panels in general waste, and failure to use an authorised carrier can result in fines of up to £5,000 under the Environmental Protection Act 1990.
