Most solar panels last 25 to 30 years or more, and when they finally retire, the bulk of their weight (glass, aluminum and copper) can be recovered. Canada's recycling system for panels is still young, but it's growing quickly: Alberta began a dedicated program with a landfill ban in October 2026, and British Columbia is adding solar panels to its producer-responsibility system. If you own panels today, the practical answer is that reuse and recycling options exist, and they're getting easier to reach every year.
Key takeaways
- Panels usually keep producing for decades. They lose a small amount of output each year (often around 0.5%) rather than failing outright.
- Roughly three-quarters of a typical silicon panel's weight is glass, with an aluminum frame, so most of the material is recoverable.
- Alberta started a provincial panel recycling program on October 1, 2026, with a landfill ban and a $14 fee on each new panel.
- British Columbia is adding solar panels to its extended producer responsibility (EPR) program, and producers are given a multi-year window to set up collection.
- Elsewhere, check with your installer, your municipality or a specialized electronics recycler. Working panels can often be resold or reused.
How long do solar panels actually last?
A solar panel has no moving parts, so it rarely "dies". Instead, it slowly produces a little less each year. Most manufacturers warrant panels to still deliver around 80 to 90% of their original output after 25 years, and many panels keep working well past that.
Panels come off roofs for a few common reasons:
- Damage: hail, a fallen branch or a cracked frame.
- Re-roofing: some owners take the chance to upgrade to newer, more efficient panels.
- Underperformance: panels from the early 2000s are far less efficient than today's.
- Moving or renovating: sometimes the array simply doesn't fit the new plan.
Many panels that come down still work. That makes reuse the first and best option, for example on a shed, a cottage (see our guide to off-grid solar for cottages) or a farm building.
What's inside a solar panel?
Understanding what a panel is made of explains why recycling is worth doing.
| Component | Approximate share of weight | Recyclability |
|---|---|---|
| Glass front sheet | ~70–75% | High, though it needs cleaning to be reused as quality glass |
| Aluminum frame | ~10–15% | Very high and valuable |
| Polymer layers (encapsulant, backsheet) | ~5–10% | Hard to recover; often burned for energy |
| Silicon cells | ~3–5% | Recoverable with specialized processes |
| Copper wiring and junction box | ~1% | High |
| Silver and other trace metals | Well under 1% | Valuable but takes advanced processing |
Figures are approximate and vary by panel type and age. Thin-film panels (less common on Canadian homes) use different materials, some of which need special handling.
How solar panel recycling works
Recycling a panel typically happens in stages:
- Removal of the frame and junction box. The aluminum and copper go straight into existing metal recycling streams.
- Separating the glass from the laminate. This is the hard part, because the cells are bonded between layers of plastic. Recyclers use mechanical shredding, heat or chemical processes to pull them apart.
- Recovering cell materials. More advanced facilities recover silicon, silver and copper from the cells themselves.
The basic "frame-and-glass" approach is widespread. Full material recovery is still emerging, and the economics are tricky: recycling a panel can cost more than its recovered materials are worth. That's why provinces are moving toward fees and producer-responsibility systems that cover the cost up front.
Where Canada stands in 2026
Canada has no single national panel recycling program. Waste is mostly a provincial responsibility, so the picture varies by where you live. You can compare general provincial energy context on our provinces page.
Alberta
Alberta, home to many of the country's large solar farms, launched a solar panel recycling program on October 1, 2026, run through the Alberta Recycling Management Authority. Two key features:
- Landfill ban: panels can no longer go to landfill in Alberta. They must be directed to reuse or recycling.
- Environmental fee: a $14 fee applies to each new panel supplied in the province. It funds collection and recycling of both new and older panels, and there's no retroactive charge on panels already installed.

British Columbia
BC has announced it's adding solar panels to the products covered by its Recycling Regulation, which uses an extended producer responsibility model. Under EPR, the companies that sell a product into the province must fund and run collection and recycling. Producers are given a multi-year window to build these systems, so full province-wide collection will phase in over time. See our BC guide.
Everywhere else
In most other provinces and territories, there isn't yet a dedicated panel program. Options typically include:
- Asking your original installer or the panel manufacturer whether they offer take-back.
- Contacting your municipality about electronics or construction-waste drop-off.
- Using a specialized recycler. A small but growing number of Canadian companies handle panels.
- Reselling or donating working panels.
Is solar still "green" if panels end up as waste?
It's a fair question. A panel's manufacturing footprint is typically paid back within a few years of clean electricity production, and then it keeps generating for decades. Panels are also a tiny share of Canada's overall waste stream compared to everyday electronics and construction debris.
The bigger issue is volume over time. Canada's solar capacity has grown quickly, so a wave of retirements will arrive in the 2040s and beyond. Building recycling systems now, before that wave, is the right move. It's a good example of the shift toward a circular economy, where products are designed and managed with their whole life in mind.

What homeowners can do today
- Keep your paperwork. Manufacturer and model details help recyclers and buyers.
- Ask about end-of-life when you buy. A good installer should be able to explain take-back or recycling options.
- Don't rush replacement. A panel at 85% of its original output is still producing plenty of clean power.
- Reuse first. A working panel on a shed or cabin beats a recycled one.

Frequently asked questions
Can I put old solar panels in the garbage?
In Alberta, no: panels have been banned from landfill since October 1, 2026. Elsewhere, rules vary, but panels contain recoverable metals and shouldn't go in household garbage. Check with your municipality or a recycler.
Do solar panels contain toxic materials?
Standard silicon panels are mostly glass, aluminum and silicon, with small amounts of lead in some solder. Certain thin-film panels contain cadmium compounds. These are safely sealed while the panel is intact, which is why controlled recycling matters at end of life.
Will I have to pay to recycle my panels?
It depends on your province. Alberta's program is funded by a fee charged on new panels, and BC's EPR model puts the cost on producers. Elsewhere, private recyclers may charge a handling fee.
The bottom line
Solar panels have a long, productive life, and their end-of-life story is improving fast. With Alberta's program now running and BC's on the way, Canada is starting to treat panels as a resource rather than waste. If you own panels, plan for reuse first and recycling second. If you're considering solar, know that the system to handle panels responsibly is being built alongside the industry itself.
