A repower crew pulls 4,000 working modules off a ten-year-old array, stacks them on pallets, and shrink-wraps them in a warehouse. Now what? Somebody has to decide whether those panels get sold, redeployed, or scrapped, and that decision is worth real money. Used modules still trade for something, recyclers still want the aluminum and silver inside them, and the wrong choice means paying to landfill an asset a buyer would have paid you for.
That warehouse scene is common now, and it is about to get more common. The equipment reaching the end of its first life today was installed during the last big buildout, and there is a lot of it. One widely cited projection from the International Renewable Energy Agency estimates that recovering panels at the end of their roughly 30-year life could put a stockpile of raw materials worth tens of millions of tonnes globally back into circulation by 2050. Some of that is genuine end-of-life waste. A surprising share is not, and that share is what this guide is about.
We compared the main places a commercial seller can move surplus and used panels in 2026, from direct buyers to wholesale exchanges to salvage auctions. For each one, we looked at what it is best for, how it pays, its reputation, and where it falls short. We put the direct buy-and-recycle option first because for most decommission jobs it is the fastest way to clear a lot, but every listing here earns its place, and every one has a catch.
Three resale channels, and four words that are not the same
Before you pick a buyer, know which kind of buyer you are talking to. There are really three channels, and they pay very differently.
A direct buyer purchases your panels outright, quotes you a price, and takes the whole lot (working stock gets resold or refurbished, the rest gets recycled). You trade a bit of upside for speed and one point of contact. A marketplace or B2B exchange lists your inventory to a network of buyers so you sell it yourself, usually for a higher price if you have the time and the volume to move it. A broker sits in the middle of a deal and works on commission, handy when you have an unusual lot and no buyer for it. Some firms blend two of these, which is why the lines below matter more than the labels.
Four terms also get used loosely, and they change what a lot is worth. Surplus panels are unused, often still boxed, left over from a cancelled or oversupplied project. Used panels have been in service and still work. Decommissioned describes panels removed from an installation, which may be either used-and-working or damaged. End-of-life means the module is done, and its value is in materials recovery, not resale. A buyer who quotes you for “surplus” and receives “end-of-life” will requote fast.
For scale, the installed base these panels come from is already enormous: an industry trade group puts the global fleet at more than 1.6 TWdc of modules installed through the end of 2023. Every one of those will eventually come down.
Where to sell used solar panels in 2026
1. Solar Recycling
Best for commercial and utility-scale decommissions that want one company to buy the good panels and responsibly recycle the rest.
Solar Recycling runs a buy-and-recycle model built for volume. Founded in 2019 by e-waste veterans, the company purchases working used panels, inverters, and battery storage for a second life, then recycles or destroys whatever cannot be reused, recovering glass, aluminum, silicon, silver, and copper. It positions itself around what it calls zero net waste and, where possible, zero net cost, meaning the value recovered from the resaleable stock is meant to offset the cost of recycling the rest. Coverage is nationwide across all 50 states, with a western-US base and interstate logistics handled as part of the job.
Reputation: no aggregated third-party review score sits on the major platforms, so judge it on the operation itself (a real warehouse, a documented five-step process, and a Certificate of Completion at the end of a recycling job).
Payout model: for resaleable used panels, it works within the going range of roughly $0.05 to $0.60 per watt (new panels run about $0.70 to $1.50 per watt), and it quotes recycling at about $20 to $50 per panel plus shipping for stock that is past resale.
The catch: this is not a fit for a homeowner with a dozen panels. The company is commercial and utility-scale by design, with a typical minimum of around 100 panels, and because it buys your lot rather than listing it, you are taking a quoted buyout price instead of chasing the top bid yourself.
2. EnergyBin
Best for solar businesses that have the time to sell wholesale lots themselves and want the highest price.
EnergyBin is a members-only B2B exchange where vetted solar companies trade panels, inverters, racking, and batteries directly with each other. You post inventory, field quote requests, and negotiate the sale yourself, with no cut taken on the transaction. The network is the product: to join, you have to run a solar-industry business, provide references, and pass a live interview, which keeps tire-kickers out.
Reputation: EnergyBin is a long-running fixture of the secondary market and is widely referenced in wholesale-equipment circles, though it carries only a handful of public third-party reviews, so its standing rests more on tenure than on a star score.
Payout model: membership is a flat subscription, listed at about $125 to $175 per month on a 12-month plan, with no per-deal fees. You keep the full sale price you negotiate.
The catch: it is a place to sell, not a buyer. If you need panels gone this week, a subscription and a self-service listing are the wrong tools, and the monthly cost only pays off if you move enough volume to justify it.
3. Surplus Solar Products
Best for sellers who want a direct buyer for mixed new-and-used inventory without a strict floor on quantity.
Surplus Solar Products describes itself as a buyer and seller of new and used excess solar inventory, working with individuals, contractors, and distribution partners. It buys surplus panels, inverters, and mounting hardware, and unlike the strictly commercial recyclers, it advertises low minimums, with stock moving by the panel or the pallet. It runs warehouses in New York, Texas, and California, and also sells through an eBay storefront.
Reputation: It is an established name in the surplus-panel niche and shows up across enthusiast and trade forums, but there is no consolidated review score to point to, so vetting comes down to references and a paper trail.
Payout model: pricing is not published. The company quotes on request, both when buying your lot and when selling from inventory, so expect a phone call or an email rather than a public number.
The catch: the by-request pricing cuts both ways. Without a listed rate, you cannot benchmark an offer quickly, and the smaller warehouse footprint means very large utility lots may be more than a single location wants to absorb at once.
4. Bluewater Battery
Best for repowering projects and jobs that mix panels with battery storage.
Bluewater Battery Logistics handles the full lifecycle of solar and storage hardware, and its surplus team buys panels, batteries, inverters, and containers, then remarkets working equipment for repowering and maintenance. The company says it has supplied over 250 MW of panels for repowering work and remarketed more than 400 MW of new surplus battery-storage containers, which tells you where its strength is: matching specific replacement modules to existing arrays and moving storage assets, not just clearing generic pallets.
Reputation: It is a recognized name in the reuse-and-repurposing space and has been covered in trade press for its growth in secondary energy markets, though, again, there is no single public star rating to lean on.
Payout model: no published pricing. You reach a named contact on the surplus team and get a quote against your specific inventory and its condition.
The catch: this is a battery-first company that also does solar, so a plain panel lot may get less attention than a mixed panel-and-storage decommission, and the quote-only approach means no instant number.
5. Salvex
Best for salvage, insurance-claim, and bankruptcy lots where a bidding process can surface a global buyer.
Salvex is a global surplus and asset-recovery marketplace that lists solar equipment alongside every other category of industrial surplus. Its sweet spot is the awkward lot: panels from insurance claims, corporate liquidations, asset recoveries, and natural disasters, sold through a bidding format to a base it says spans 200 countries. If your panels are damaged, mismatched, or tied to a claim, this is the channel built for that.
Reputation: Salvex carries a low customer-review score, around 2.2 out of 5 across several dozen buyer and seller reviews on Trustpilot, with recurring complaints about communication and closing deals, so go in with your terms in writing.
Payout model: it runs on bids against a listed asking price, and the platform takes its margin on the transaction rather than charging a flat fee, so your net depends on what the auction actually draws.
The catch: an auction is uncertain by nature. You may get a strong global bid, or you may get a thin one, and the mixed reviews mean the process can be slower and more hands-on than a direct buyout.
6. PVRecycling
Best for panels that are genuinely done, where compliance and landfill diversion matter more than resale.
PVRecycling focuses on recycling large-scale commercial, industrial, and utility-grade panels rather than reselling them. It works with EPCs, contractors, developers, and installers across all 50 states, handling the panels that come down after construction breakage, storm damage, or a repower with newer technology. The pitch is proper end-of-life processing and documented material recovery, not a resale check.
Reputation: Like most firms in this corner of the market, it does not carry a public aggregate rating, so its credibility rests on its stated recovery process and its commercial-only focus.
Payout model: this is a recycling service, not a buyer, so there is no per-watt payout. Pricing is quoted per project, and the value to you is compliance and diversion rather than a resale return.
The catch: it explicitly does not buy panels for resale and does not work with residential owners, with a typical minimum of hundreds of panels, so if any of your stock still works, you will leave resale money on the table by routing everything here.

How to verify used panel quality before you buy or sell
Whether you are buying or selling, the money is in the grading. Panels that look identical on a pallet can be worth wildly different amounts once someone tests them, and a serious buyer will always test.
Start with the condition and grade. Most of the trade sorts panels into an informal A, B, and C system: A-grade is fully working, cosmetically clean, often near original spec; B-grade works but shows wear, microcracks, or lower output; C-grade is for parts or recycling. There is no universal standard behind those letters, so ask what each grade means to the specific counterparty. Back the grade with numbers. A flash-test report, which measures a panel’s actual power output under standard test conditions, is the document that matters because it verifies the real wattage (Wp) instead of the nameplate. If a seller cannot produce flash-test data on a used lot, treat the rated wattage as a starting claim, not a fact.
The age math matters too. Panels lose a little output every year, and the long-running review from a national renewable-energy lab found a median loss rate of about half a percent per year across thousands of measured modules. So a twelve-year-old panel rated at 300 watts when new is realistically producing somewhat less, and your valuation should reflect that, not the sticker. Do a physical inspection on top of the paperwork: look for cracked or delaminated glass, burn marks at the junction box, corroded connectors, and frame damage. On a large lot, sample and test a representative batch rather than trusting one clean pallet to speak for a whole warehouse.
Warranty and specs on decommissioned systems
Buyers of commercial decommission stock ask two questions early: what exactly is this equipment, and does any warranty come with it? Get the answers in writing before a lot changes hands.
For specs, pull the module datasheet by make and model, confirm the wattage class, cell type, and connector, and match it against the panels in front of you. Serial numbers let a buyer check manufacture date and, sometimes, the original warranty status. Warranty transfer on decommissioned commercial systems is the part that people get wrong. Manufacturer performance warranties often run 25 years, but many are written to the original owner or the original installation site and do not automatically follow the panel to a new owner. Some transfer once, some not at all, and a manufacturer that has gone out of business (several large panel makers have) leaves the warranty worthless regardless of the paper. Treat any remaining warranty as a bonus you have confirmed in writing, never as a given.
How to vet a buyer or supplier
The market has plenty of good operators and a few that will waste your month. A short checklist separates them. Confirm the company actually operates a facility or a vetted network rather than drop-shipping from a spare room. Ask for references from comparable commercial deals, not a single testimonial. Get the price basis in writing, whether that is per watt, per panel, or a bid, and get who pays freight in writing too. Ask how they handle the panels you cannot sell, because responsible recycling with documentation is a real differentiator, and a landfill run is a liability. And be wary of anyone who quotes a great number sight unseen, then drops it after “inspection.” A credible buyer prices from your flash-test data and photos up front.
Where the surplus is: bulk and commercial decommissions
If you are sourcing bulk stock rather than selling it, the surplus follows the buildout. The heaviest concentrations of decommissioned and surplus commercial panels track the regions that installed the most capacity first: California and the broader Southwest (Arizona, Nevada), Texas, and the Southeast, plus pockets tied to specific utility repowering programs. Storm-heavy regions produce irregular surges of insurance claim lots. And there is a genuine outlier: island markets like Hawaii, where early adoption plus limited local recycling makes end-of-life panels a real logistics problem rather than a resale opportunity.
For very large utility volumes, two paths dominate. Direct buyers and recyclers who can absorb a whole array in one transaction are the simplest, and wholesale exchanges (EnergyBin, and marketplaces such as Sunhub) let you place large lots in front of many buyers at once. Off-taker arrangements, where a repowering firm or a large refurbisher commits to take a defined volume, are common for utility repowers because they turn an unpredictable disposal problem into a scheduled pickup.
Frequently asked questions
How much are used solar panels worth in 2026? Working used panels generally trade for roughly $0.05 to $0.60 per watt, against about $0.70 to $1.50 per watt for new. Where a specific lot lands in that range depends on grade, tested wattage, age, quantity, and how well it is documented. Damaged or end-of-life panels are valued for their recoverable materials instead, and recycling a panel that cannot be resold typically runs about $20 to $50 each plus shipping.
Which regions have the most surplus inventory? The early, high-volume solar markets: California and the Southwest, Texas, and the Southeast, which is where the first large commercial arrays are now reaching repower age. Storm-prone areas add bursts of insurance-claim stock, and island markets such as Hawaii carry an outsized end-of-life burden relative to their size.
Can I sell panels still under warranty? Often yes, but the warranty may not travel with them. Many commercial manufacturer warranties are tied to the original owner or site and either transfer once or not at all, and a defunct manufacturer voids the point entirely. Confirm transferability in writing with the manufacturer before you promise it to a buyer, and price the lot on tested condition rather than on the warranty.
Marketplace, direct buyer, or broker: which is fastest? A direct buyer is usually faster because one company quotes and takes the whole lot. A marketplace can pay more but you do the selling, and a broker is worth it mainly for unusual lots that need a matchmaker.
The bottom line
There is no single best place to sell used panels, only the right channel for the lot in front of you. If you have time and volume, a wholesale exchange gets you the top price. If your panels are damaged or tied to a claim, a salvage auction is built for that. And if you are clearing a commercial or utility decommission and want the working panels bought and the rest recycled with documentation in one move, a direct buy-and-recycle operation is the least painful path. On that last route, if you are looking to sell used solar panels off a commercial or utility array and want one buyer to handle both the resale and the responsible recycling, Solar Recycling built its whole model around that job for lots of about 100 panels and up. Whichever way you go, grade the panels, get the price basis in writing, and confirm where the unsellable stock ends up before you ship a thing.
