End-of-life solar, answered
Solar panels typically last about 25 to 30 years, and when they retire most of the panel can be recovered. Roughly 75% of a panel by weight is glass, and the glass, the aluminum frame, the copper wiring, and the silicon are all recyclable (EPA, as of July 2026). The honest catch: recycling one panel costs about $15 to $45 today versus roughly $1 to $5 to landfill it (NREL figures, as widely reported, 2026), so recycling is still scaling up, and no US federal law requires it yet.
Updated for 2026. Solar panel recycling is a fast-moving field, so the costs, the recyclers, and the state rules in this guide are kept current for the year.
When people install solar, almost nobody asks what happens to the panels in 2050. It is a fair question, and a genuinely useful one, because a solar panel is a 25 to 30 year product that eventually comes off the roof. This guide covers what “end of life” really means, how solar panel recycling works, what a panel is made of, why recycling still costs more than a landfill today, which states regulate disposal, and exactly where a homeowner can take old panels. We have kept it balanced on purpose: panels are highly recyclable in principle, and the industry is still building the capacity to prove it at scale.
How long do solar panels last before they need recycling?
Most panels run 25 to 30 years, and “end of life” is an economic call, not a sudden death. A modern crystalline-silicon panel does not stop working at year 25. It slowly makes a little less power each year, losing on the order of 0.5% of its output annually in typical field conditions, which leaves a panel still producing the large majority of its original power after 25 years. The US Department of Energy now describes a 25 to 35 year service life for panels installed today, up from about 20 years in 2007 (US Department of Energy, as of July 2026). “End of life” usually arrives when a panel is damaged, when a system is repowered with newer higher-output panels, or when a roof or home is sold, not because the panel failed.
That timing is why the recycling wave is still ahead of us. The vast majority of panels ever installed are still on roofs and still under warranty, so relatively few are entering the waste stream right now. The Department of Energy expects far more panels to reach end of life over the next few decades, which is the surge the recycling industry is preparing for today (US Department of Energy, as of July 2026). If you want the bigger picture on lifespan and whether the long-term math works, see our financial analysis of whether solar panels are worth it.
What are solar panels made of, and how much can be recycled?
A solar panel is mostly glass and aluminum, which is good news for recycling. By weight, a standard crystalline-silicon panel is dominated by glass, then the aluminum frame, then a layer of polymers, with only small amounts of silicon and a trace of high-value metals like copper and silver. The EPA confirms glass makes up about 75% of the weight, and that the glass, aluminum frames, copper wire, and silicon are recyclable through established processes (EPA, as of July 2026).
Here is our own breakdown of what is inside a typical panel. The table below is MySolarFY’s estimate: we take a typical residential panel weight of about 20 kilograms and apply the published composition ranges to show roughly how much of each material a single panel holds. Treat the kilogram figures as estimates, since panel designs vary.
| Material | Share of panel by weight | Approx. weight in a 20 kg panel | Recyclable today? |
|---|---|---|---|
| Glass | About 75% | About 15 kg | Yes, established glass recycling |
| Aluminum frame | About 8% to 10% | About 2 kg | Yes, high-value metal |
| Polymers (encapsulant and backsheet) | About 9% to 10% | About 2 kg | Hardest part, often burned or landfilled |
| Silicon cells | About 3% to 5% | About 0.8 kg | Recoverable, needs extra processing |
| Copper, silver, and other metals | Less than 1% to 2% | About 0.3 kg | Yes, but tiny amounts |
MySolarFY estimate for a typical 20 kg residential panel, using composition ranges from the EPA and NREL as reported (as of July 2026). Actual weights vary by panel.
So how much of a panel is really recyclable? Be careful with the big numbers. You will see claims that panels are “90% to 95% recyclable,” but no US agency (the EPA, NREL, or the DOE) publishes a single official recyclable-by-mass figure, so we do not present one as fact. What is solid: glass and aluminum together are the large majority of the panel by weight and both recycle cleanly, so the recoverable share is genuinely high. The honest nuance is that recovering the last stubborn fraction, the bonded polymers and the high-purity silicon, is harder and more expensive than melting down the glass and aluminum.

How does solar panel recycling actually work?
Recycling a panel is a teardown, not a single machine. A retired panel runs through a sequence of steps that peel it apart and sort the pieces. Bulk materials like glass and aluminum come off first and easily, while the valuable silicon and silver take extra chemical or thermal work to recover (EPA, as of July 2026). A typical process looks like this:
- Disassembly. The aluminum frame and the junction box are removed by hand or machine and sent straight to metal and plastic recycling.
- Delamination. The bonded layers (glass, encapsulant, cells, backsheet) are separated using heat, mechanical force, or chemical treatment. This is the hard, expensive step.
- Shredding and size reduction. The remaining laminate is crushed and shredded into a mixed stream of glass cullet, silicon, and metal bits.
- Separation. Screens, density sorting, and air classification split that stream into recovered glass, silicon, copper, and silver.
- Finishing. High-value fractions like silicon and silver go through further hydrometallurgical or thermal refining to reach a reusable purity.
The economics explain the design. Glass and aluminum are cheap to recover and worth relatively little, while silver and high-purity silicon are worth more but cost more to extract. That gap is exactly why a basic recycler focuses on glass and aluminum and why advanced recyclers are racing to capture the silicon and silver profitably.
Does recycling solar panels cost more than landfilling them?
Yes, and this is the honest heart of the issue: recycling a panel costs more than throwing it away. The US Department of Energy states plainly that the total cost of recycling a panel is still generally greater than the cost of disposing of it in a landfill (US Department of Energy, as of July 2026). Putting numbers on that gap: recycling a single crystalline-silicon panel in the US runs about $15 to $45, while sending that same panel to a landfill costs roughly $1 to $5 (NREL figures, as widely reported by Earth911, 2026). By MySolarFY’s analysis of those figures (as of July 2026), recycling therefore costs roughly 5 to 30 times as much as landfilling, and the recoverable materials inside a typical panel are worth only about $3 to $12, so the recovered value rarely covers the recycling bill on its own.
| Recycling a panel | Landfilling a panel | |
|---|---|---|
| Typical US cost (2026) | About $15 to $45 | About $1 to $5 |
| What happens to the materials | Glass, aluminum, silicon, and metals recovered and reused | Buried; materials lost |
| Environmental outcome | Keeps materials in use, avoids new mining | Wastes recoverable material, small leaching risk if hazardous |
| Availability today | Growing but not everywhere | Widely available and cheap |
| The catch | Costs more, and value recovered is only about $3 to $12 | Some states now restrict or ban it |
Cost figures are NREL estimates as widely reported in 2026; real-world landfill costs can run higher once transport and any hazardous-waste handling are included.
Are there panels worth money in scrap? Barely, and that is the point. A common question is whether old panels have real scrap value, especially the silver. Modern panels contain only a trace of silver and copper, well under 1% to 2% of the panel by weight, and manufacturers keep thinning the silver to cut costs. That is why the recoverable value sits at only about $3 to $12 per panel and why recycling does not yet pay for itself at small volumes. Recycling solar panels becomes profitable mainly at large scale, or once regulations or higher landfill fees tilt the math.
The number a homeowner planning a removal actually needs is the cost to recycle a whole array. A typical residential system of about 20 panels weighs roughly 400 kilograms, of which about 300 kilograms is glass and about 40 kilograms is aluminum. Scaling the per-panel figures above, here is MySolarFY’s estimate for recycling versus landfilling a full 20-panel array (as of July 2026):
| A typical 20-panel home array | Recycle | Landfill |
|---|---|---|
| Cost per panel (US, 2026) | $15 to $45 | $1 to $5 |
| Total cost for about 20 panels | About $300 to $900 | About $20 to $100 |
| Recoverable material value | About $60 to $240 (roughly $3 to $12 per panel) | $0, materials buried |
| What is recovered | About 300 kg glass and 40 kg aluminum, plus silicon and metals | Nothing |
MySolarFY estimate (as of July 2026): the per-panel recycle and landfill costs are NREL figures as widely reported (2026), scaled to a typical 20-panel array; the recoverable value uses the roughly $3 to $12 per panel range from NREL-linked recycling analysis. Figures are illustrative and vary by recycler and location.
Do not just toss panels in your household trash. Some panels can fail the EPA’s toxicity test for metals like lead and cadmium, which can make a discarded panel a regulated hazardous waste, and several states now restrict putting panels in ordinary landfills (EPA, as of July 2026). If you are removing panels, treat them as electronic waste and check the disposal steps below.
Do you have to recycle solar panels? US laws and regulations in 2026
There is no federal law that forces you to recycle solar panels, but the rules are tightening. As of 2026, no US federal statute mandates solar panel recycling. Under federal hazardous-waste rules, a discarded panel is first treated as solid waste, and it only becomes regulated hazardous waste if it fails the toxicity characteristic leaching procedure, the TCLP test, for metals such as lead or cadmium (EPA, as of July 2026). Some panels pass that test and some fail, depending on their design. The EPA opened a rulemaking effort in October 2023 to add end-of-life panels to its streamlined “universal waste” program, but that federal rule is not final yet.
States are moving faster than Washington, D.C. Several states already regulate end-of-life panels through their own universal waste programs, including California, Hawaii, New Jersey, North Carolina, and Washington (EPA, as of July 2026). Washington State went furthest, passing the first US solar module stewardship law that puts the responsibility for end-of-life recycling on panel manufacturers. In practice, that stewardship design is meant to shift the recycling cost onto the manufacturer rather than the homeowner, so an eligible Washington resident may pay little or nothing to recycle a qualifying panel. Most other states have no such backstop yet. Because the rules differ by state and keep changing, the EPA advises homeowners to confirm their own state’s status by contacting their state environmental or recycling agency before disposing of panels.
| Where you live | What it usually means for disposal |
|---|---|
| A state with a universal waste or stewardship rule (for example CA, HI, NJ, NC, WA) | Panels are regulated at end of life; landfilling may be restricted and a recycling or take-back path is expected |
| Most other states | No specific solar recycling mandate yet; a panel that fails the TCLP test is still regulated as hazardous waste federally |
| Everywhere | No federal recycling mandate; recycling is voluntary but encouraged, and household-trash disposal is not appropriate |
What about tax breaks for recycling? There is no federal tax credit for recycling a solar panel, and the federal residential solar tax credit itself (Section 25D) ended for expenditures made after December 31, 2025, so a homeowner installing or servicing solar in 2026 cannot claim it. For what that change means, see our guide to the end of the federal solar tax credit.
Where and how do you recycle old solar panels?
You have four realistic paths, and a phone call is the right first step. Most municipal recycling centers cannot process a solar panel, so calling ahead saves a wasted trip. The EPA points homeowners to three finders: the Department of Energy’s solar manufacturing and recycling map, the electronics-recycling locator Earth911, and the Solar Energy Industries Association (EPA, as of July 2026). Here is how the options compare:
| Option | How it works | Best for |
|---|---|---|
| Manufacturer take-back | Some panel makers accept their own products back for recycling, and in Washington State this is required by law | Panels still identifiable by brand, or homeowners in stewardship states |
| SEIA recycler network | The Solar Energy Industries Association runs a national recycling program, a vetted network of recyclers you can find through its SolarRecycle locator | Finding a certified recycler near you |
| Dedicated PV recyclers | Specialist recyclers such as SOLARCYCLE and We Recycle Solar process panels directly, usually for a per-panel fee | Larger removals or when no local option exists |
| Municipal or e-waste facility | Some electronics-waste programs accept panels; many do not, so call first | A single panel, only if the facility confirms it takes them |
If you are having a system removed, let the installer handle it. When panels come off during a roof replacement, a repowering, or a decommissioning, the crew doing the work can usually route them to a recycler for you, and that is the simplest path for most homeowners. Use the Solar Energy Industries Association’s SolarRecycle locator to check for recyclers in your area (SEIA, as of 2026). If you are early in your solar journey, our solar basics guide walks through the full ownership lifecycle from install to end of life.
Is solar still worth it if panels are hard to recycle?
Yes, and being honest about recycling is part of why. A solar panel offsets far more carbon over its 25 to 30 year life than it takes to make and eventually recycle it, and the recycling gap is a cost and logistics problem, not a reason the technology fails. The materials, mostly glass and aluminum, are recyclable and valuable in aggregate, the volume of retired panels is still small, and the recycling industry is scaling capacity ahead of the wave the Department of Energy expects (US Department of Energy, as of July 2026). The US Department of Energy expects the United States alone to generate between 0.17 and 1 million tons of end-of-life panels by 2030 (US Department of Energy, as of July 2026), and globally, cumulative panel waste could reach up to 78 million tonnes by 2050 (IRENA, 2016). That coming wave is exactly why building recycling capacity now matters.
For a homeowner, the practical takeaway is simple. Buy quality panels with strong warranties so they last their full life, keep the paperwork so the panels stay identifiable at end of life, and plan to recycle rather than landfill when the day comes.

Frequently asked questions
Can solar panels be recycled?
Yes. Most of a solar panel can be recycled, because a crystalline-silicon panel is mostly glass (about 75% by weight) plus an aluminum frame, and both recycle through established processes, along with the copper wiring and silicon inside (EPA, as of July 2026). The harder parts to recover are the bonded polymer layers and the high-purity silicon, which take extra chemical or thermal processing. No US agency publishes a single official recyclable-by-mass percentage, so treat the “90% recyclable” claims you see online as industry estimates rather than confirmed facts. The recovered materials are real, but recycling still costs more than a landfill today.
How much does it cost to recycle a solar panel?
Recycling a single crystalline-silicon panel in the US costs roughly $15 to $45, while landfilling that same panel costs about $1 to $5, based on NREL figures as widely reported in 2026 (Earth911, 2026). The recoverable materials inside a panel are worth only about $3 to $12, so recycling does not pay for itself at small volumes. That cost gap is the main reason recycling is still scaling up rather than being universal. Real-world landfill costs can run higher once transport and any hazardous-waste handling are added, which narrows the gap in some states.
Are old solar panels worth anything in scrap?
Not much on their own. A modern panel contains only a trace of high-value metal, with silver and copper together making up less than 1% to 2% of the panel by weight, and manufacturers keep reducing the silver to save money. The total recoverable material value is only about $3 to $12 per panel, which is why individual panels have little scrap value and why recycling generally becomes profitable only at large scale (NREL figures, as widely reported, 2026). The bulk materials, glass and aluminum, are recyclable but individually low in value, so the economics work best when a recycler processes many panels at once.
Do I have to recycle my solar panels by law?
As of 2026, no US federal law requires you to recycle solar panels. A discarded panel is treated as solid waste federally, and it becomes regulated hazardous waste only if it fails the EPA’s toxicity test (the TCLP) for metals like lead or cadmium (EPA, as of July 2026). Several states, including California, Hawaii, New Jersey, North Carolina, and Washington, regulate end-of-life panels through universal waste or stewardship programs, and some restrict landfilling. The EPA advises contacting your state or local recycling agency, since the rules differ by state and are changing quickly.
Where can I recycle old solar panels near me?
Start with a phone call, because most municipal centers cannot process panels. The EPA points homeowners to three finders: the Department of Energy’s solar recycling map, Earth911, and the Solar Energy Industries Association’s SolarRecycle locator, which lists vetted recyclers (EPA, as of July 2026). Your options are manufacturer take-back (required in Washington State), the SEIA recycler network, dedicated PV recyclers such as SOLARCYCLE or We Recycle Solar, and some electronics-waste programs. If an installer is removing your system, they can usually route the panels to a recycler for you, which is the simplest path.
Is there a tax credit for recycling solar panels?
No. There is no federal tax credit for recycling a solar panel. Separately, the federal residential solar tax credit (Section 25D) ended for expenditures made after December 31, 2025, so a homeowner who installs or services solar in 2026 cannot claim that 30% federal credit either (MySolarFY, the end of the federal solar tax credit). Some states still offer their own solar incentives, and end-of-life costs in stewardship states like Washington may be covered by manufacturers rather than the homeowner. MySolarFY does not provide tax advice; confirm your situation with a tax professional.
What happens to solar panels at the end of their life?
When a panel retires after about 25 to 30 years, it comes off the roof and should be recycled rather than landfilled. At a recycler it is taken apart in steps: the aluminum frame and junction box are removed, the bonded layers are separated by heat or chemistry, and the remaining material is shredded and sorted into recovered glass, silicon, copper, and silver (EPA, as of July 2026). Glass and aluminum are recovered easily, while silicon and silver need more processing. The Department of Energy expects far more panels to reach this stage over the coming decades, which is why recycling capacity is being built now.
