What to Do With Old Solar Panels and Inverters in Australia

Australia installed solar faster and earlier than almost anywhere else in the world, which means a growing wave of panels, inverters and portable kits are now reaching end of life — either through genuine failure, degradation below a useful output threshold, or simply being swapped out for a newer, more efficient kit. Unlike a broken appliance, solar hardware contains materials that shouldn't just go in general waste, and in some states you're legally required to dispose of it a specific way. Here's what actually happens to old solar gear, and how to do it properly.

Why you can't just bin a solar panel

A standard crystalline silicon solar panel is roughly 70-80% glass by weight, with an aluminium frame, copper wiring, and trace amounts of silver, lead and sometimes cadmium depending on the cell technology. None of that belongs in a kerbside general waste bin — most councils explicitly prohibit it, and landfilling intact panels wastes genuinely recoverable glass and aluminium that recycling facilities can process. Micro-inverters, the component covered in our CEC-approved inverters guide, contain circuit boards and capacitors that fall under e-waste rules in every state, separate from the panel itself.

Victoria bans solar panels from landfill outright

Victoria is currently the only state with an outright ban on sending photovoltaic panels to landfill, enforced since mid-2020 as part of the state's broader e-waste reforms. If you're in Victoria, a licensed recycler or an approved e-waste drop-off point is your only legal disposal route — check with your local council for the nearest accredited facility before assuming your usual tip or transfer station will take panels. Other states don't yet have an equivalent blanket ban, but several — including NSW and South Australia — are moving toward similar e-waste product stewardship schemes, so check your state's current rules rather than relying on what was true a year or two ago.

What actually gets recycled, and what gets lost

Commercial panel recycling in Australia typically recovers the glass (around 70% of panel weight), the aluminium frame, and the copper wiring — all genuinely reusable materials. The silicon wafers and rarer metals embedded in the cells themselves are harder and more expensive to recover, so a meaningful share of a panel's value is effectively lost in current-generation recycling processes rather than fully recovered. This is an active area of improvement in the industry, but it's worth knowing that "recycled" doesn't currently mean "fully recovered" — it mostly means the bulk materials are diverted from landfill rather than every component being reclaimed.

Check your warranty before you assume it's dead

Before recycling anything, confirm it's actually beyond repair or replacement. Most panels carry 10-25 year product and performance warranties, as covered in our solar panel warranty guide — a panel underperforming well within its warranty period may be eligible for manufacturer replacement rather than disposal. The same applies to failed inverters and batteries; our solar battery cost guide and best solar batteries guide both note typical warranty terms worth checking before you write off a unit as dead.

Portable and plug-in kits are generally easier to deal with

If you're retiring a smaller portable or plug-in setup rather than a full rooftop array — the kind covered in our off-grid solar guide — disposal is usually more straightforward. These units are lighter, smaller, and more likely to be accepted through standard household e-waste collection points than a full-size rooftop panel, which often needs a specialised recycler due to its size and glass content. Many retailers and manufacturers now also offer take-back programs for exactly this reason, so it's worth checking with the original seller before assuming you need to find a third-party recycler yourself.

Where to actually take it

Start with your state EPA or local council website, since rules and accredited facilities genuinely differ by state and change as schemes expand. Several battery and electronics retailers also participate in national e-waste collection networks that accept small inverters and batteries alongside general electronics — useful if you're disposing of a failed component from a plug-in or portable kit rather than a full rooftop system.

Rebate and upgrade timing

If you're disposing of old gear because you're upgrading, it's worth checking current STC rebate eligibility on the replacement before you commit — rebate values shift periodically, and timing a disposal and upgrade together can reduce the net cost of the swap.

Can I put a dead solar panel in my regular household bin?

No. Solar panels contain glass, aluminium and trace amounts of hazardous materials that most councils explicitly exclude from general waste. In Victoria it's an outright legal ban; elsewhere it's still against most councils' waste rules even without a specific state-wide ban.

Do solar batteries and inverters need special disposal too?

Yes. Both fall under e-waste rules in every state due to the circuit boards, capacitors and (for batteries) chemical cells involved. Treat them the same as other household electronics or battery e-waste, not general rubbish.

Is there any value in recycling an old solar panel, or is it just a cost?

Recyclers typically recover the glass, aluminium frame and copper wiring, which has some scrap value, but current processes don't fully recover the silicon cells or rarer embedded metals — so most households should expect disposal to be low-cost or free through an accredited scheme rather than a source of significant payment.
