First generation of solar panels is wearing out – A recycling industry is salvaging them.
The unverified price I have heard for purchase and installation of solar cells is in the realm of $30,000. I have heard the electric district we are in which is District #3 drags their feet in approving installations. Why that would be, I am not sure.
Our monthly electric bill for a 1500 square foot home is approximately $125 per month. Summer months supersede the $125 and Fall through Winter it can be less than half. I am testing the $125 assumption as I write. Last month the cost was $149. I expect this month to be higher. I have built up a reserve to cover the excesses.
In comparison, our realtor who helped us obtain this home had an electric bill of ~$600 last month on a two-level 3000 square foot home. Our attic is cool thanks to the insulation in it. The two x six wall allow for additional open cell insulation with the standard 1-inch-thick foam board layer over the studs. The temperature is set at 78 right now and the outside temp is 105 degrees. Making it cooler makes no sense.
Just some thoughts. Anyway, in Yuma, AZ; they are recycling old solar panels. Some can be reused with a bit of refurbishing and sold again. The rest are broken down into recyclable components. Still, a majority of scrapped solar panels go to landfills which some companies like the one in the story salvage for materials. More to read in the AP News story below.
Oh, and the need for solar panels for us? I think we will pass for now.
The first generation of solar panels will wear out. A recycling industry is taking shape, AP News, Isabella O’Malley.
Sunlight beats down on a graveyard for dead solar panels in Yuma, Arizona, hundreds stacked in neat piles, waiting for their next life. The great majority of worn and damaged panels are still dumped in landfills. But with more and more piling up, many people know that needs to change.
In this desert city where Arizona, California, Sonora and Baja California meet, North America’s first utility-scale solar panel recycling plant has opened to address what founders of We Recycle Solar call a “tsunami” of solar waste. Plans to address climate change rely on massively scaling up clean, solar electricity.
The panels, stacked and banded, come here from the company’s main collection warehouse in Hackettstown, New Jersey, plus six other locations across the country.
Workers maneuver the stacks into the sprawling 75,000 square foot facility on forklifts, then gently lift each out by hand to begin separating by brand and model. Some only have a few cracks in their glass, sometimes from storm damage. These forklift operators undergo specialized Forklift Training to ensure safe and efficient handling of the equipment, contributing to the smooth operation of the sorting process.
These can be reused, said Adam Saghei, CEO of We Recycle Solar, and there is a market for them — clients around the world who search for refurbished panels for their affordability. The Yuma facility, he says, is like “your local thrift store that looks to upcycle.”
For example, some have been sold at the store Mercados Solar in Carolina, Puerto Rico.
Those that don’t go towards testing and resale head down a conveyor belt where glass, metals, and other materials with value are separated.
Solar panels are built to withstand decades of harsh weather, so it’s difficult to break the resilient bonding that keeps them together. Separating the glass without it shattering, for example, is a challenge. But with robotic suction arms assisted by workers, they come apart. You can visit this site to for more info about solar panels.
Some of the highest value materials are copper, silver, aluminum, glass, and crystalline silicon. Repurposing these means finding new uses for them, such as selling glass to companies that do sandblasting.
For Saghei, the inspiration for the company came in 2017. He was working in the computer electronic waste sector, seeing solar spread across warehouse roofs and wondering where it would go eventually. He realized green technology doesn’t stay green once it is decommissioned or retired.
“Solar energy is a great technology, but it can feed a whole industry like aluminum and glass. Why are we spending tens of millions of dollars on these materials from overseas when we can produce them right here, right now?” he thought.
Copper is one metal the recycling yields, said Dwight Clark, director of compliance and recycling technology at We Recycle Solar, as others nearby sorted incoming panels. “Granted, it’s not a lot of pounds per solar panel. But when we do 10,000 pounds of solar panels an hour, we end up with a hundreds pounds of copper an hour coming out of it,” he said.
“The aluminum … could come back as more solar panel frames or it could go into the flight deck of a new Boeing aircraft.”
By 2050, solar waste will total some 78 million tons globally, said Mool Gupta, a professor in the Department of Electrical and Computer Engineering at University of Virginia. The reason recycling and recovery isn’t robust yet, Gupta said, is that companies struggle to justify the $30 per panel cost when it costs only $1 to send it to a landfill.
If we hope to one day see 100% of retired solar recycled, said Garvin Heath, distinguished member of the research staff at the Department of Energy’s National Renewable Energy Laboratory, “Let’s not make it any more expensive than what it would cost to landfill the module … let’s not have it cost the consumer anything and instead have it break even for the recycler.”
Other companies are starting to get into the business.
Solarcycle, a startup based in Odessa, Texas, raised $30 million earlier this year, led by Fifth Wall, an asset manager focused on building decarbonization. And Solarpanelrecycling.com is an affiliate of electronics recycler PowerHouse Recycling.
The European Union has rules that require recycling of electronic waste under its Waste Electrical and Electronic Waste Directive (WEEE).
Market researcher Visiongain estimates the global market at US $138 million for last year and growing fast, boosted in part by incentives offered in the Inflation Reduction Act in the U.S.
As fast as possible, Jack Groppo, professor of mining engineering at the University of Kentucky, says, people have to stop scrapping the modules. “Once the solar panels go into the landfill, they’re gone unless we go back and mine the landfill,” he said.
Groppo estimates that in 20 years people will mine landfills to recover valuable materials in the junked panels, but “it makes an awful lot more sense for us to separate them now.”
The Yuma facility can process 7,500 panels in a single day or roughly 69 million pounds per year. As of early June, it estimates more than 650,000 tons of carbon dioxide have been avoided. It is reusing about 60% of the panels that come in.
The company plans to open another recycling facility alongside a large solar manufacturer in the Georgia, North Carolina and South Carolina corridor.
For now, solar recycling companies are still figuring out how to make money. We Recycle Solar sends out employees to dismantle large solar arrays and that is currently its biggest source of revenue. Reselling refurbished solar panels is number two, and recycling brings in the least. Decommissioning and resale are actually subsidizing some of the recycling costs, Saghei said.
But Gupta said these profitability challenges are temporary and will be overcome. Researchers are hard at work on solving them, he said.
“Too many lives are lost to pollution and solar is one of the top solutions.”

China’s PV sector develops recycling tech for retired modules
BEIJING — China, the world’s largest producer and user of photovoltaic (PV) modules, will face massive retirement of PV modules, which have service lives of about 25 years.
The country’s PV industry and researchers are working to find sustainable and economical ways to recycle the coming tens of millions of tonnes of retired modules.
MASSIVE RETIREMENT
The International Renewable Energy Agency predicts that by the time the first batch of PV modules come to the end of their service, China will have a large number of PV modules retired from 2025 onwards.
In 2030, the retired PV modules are expected to reach about 8 million tonnes globally and the figure in 2050 will be 80 million tonnes. China will need to recycle 1.5 million tonnes in 2030, and about 20 million tonnes in 2050.
PV modules are mainly composed of glass, backplate, battery, aluminum frame, brazing tape and junction box. Most of these materials, such as glass, copper, aluminum, silicon, silver, gallium and indium, can be recycled. The fluorine-containing backplate, however, is difficult to recycle and has the potential to pollute the environment.
The estimates also show that waste from the PV industry is expected to reach 350,000 to 1.55 million tonnes in China by 2027, and 33.5 million tonnes by 2050. This will be distributed in areas spanning 5 million hectares, becoming new “mines” for the industry to explore.
RECYCLING TECHS
In China’s provincial-level regions such as Jiangxi, Hebei, Henan, Jiangsu and Ningxia, enterprises, universities and research institutes have begun to develop recycling technologies for this untapped field, including mechanical disassembling, physical decomposition and chemical decomposition. Several pilot programs and demonstration lines have been completed or put into operation.
In April, Li Jin, a professor with the School of Materials and New Energy, Ningxia University, led a team in field research at PV power stations built about 15 years ago in the Ningxia Hui Autonomous Region.
The team tested PV modules at those stations to find their defects after years of service and calculated their power generation efficiency to determine when to retire those modules.
Li’s team has invented several types of equipment to disassemble PV modules. One can peel off the components of PV modules layer by layer, while another works like a hot knife to cut through panels with defects.
It’s easy to disassemble PV modules into different parts, just like cars and televisions, but how to reuse the parts with high added value is a more difficult challenge, said Li, whose team plans to develop a disassembling machine to automatically sort disassembled materials for subsequent processing.
The disassembling and recycling of retired PV modules is profitable. According to Li, it takes 30 yuan (about 4.16 U.S. dollars) to buy a retired module. The raw materials disassembled and separated from it, such as glass, aluminum, polymer backplate, silicon, silver, indium and gallium, are worth more than 200 yuan….
China produces the most efficient solar panels, however the United States has made Chinese panels either very costly by the imposition of tariffs or forbidden the use of Chinese panels simply because of where they are made. China also has developed robotic cleaners for solar panels. Also, China has now developed unique high efficiency flexible solar film; that evidently will not be allowed in the US.

China sets record to enhance efficiency of perovskite solar battery
Chinese researchers have set a new record by increasing the power conversion efficiency of perovskite solar cells up to 25.4 percent, according to a research article * recently published in the journal Science.
As the third generation of solar cells, perovskite solar cells feature high efficiency upper limit, low costs and flexible physical properties. They are regarded as a revolutionary new material….

Ten years ago, we purchased 22 rooftop solar panels with microinverters and reversible meter for $24K for our house in St. Louis. Ameren paid half of that and we got a 30% tax rebate on the rest, so we planned to pay $8400. We got a further $1000 back from the panel company for referring a buyer, so we were out of pocket $7400. We sold the house last year, and so we saved about $5500 on electric during the nine years we had rooftop solar. The panels were warranteed for 25 years.
I recommend that anyone contemplating rooftop solar get an energy audit of their house and optimize it for conservation first. You could realize significant savings that way.
We were told we’d get our investment back in 7-8 years. I figured at that time that was bogus. Maybe the panels and labor are cheaper now, but go in with your eyes open. Commercial perovskite cells are apparently finally coming on the market this year. It will be interesting to see if their yield and durability match the previous generation of cells.
interesting comments all. there are some reports on internet that solar costs a lot more than you expect. perhaps due to some unethical practices. interested parties should at least try google and follow up in the real world.
at a 105 degrees outside i have no real succor, but i’d try for 80 inside (dress for it) and see if it saves you some money. real Southwestern archtecture should save a lot…but it may be too late for you for that. Pity the poor Navaho in his hogan…or not.
the idea of a thermostat makes my blood run cold, but after three or four looks at Phoenix I decided I wouldn’t like living there anyway. I did get through more than a few years in florida without a thermostat. got sweaty a few times, but a person can adapt.
oh, yeah, back in the day i thought like everyone else solar was the way to go, but my inner
scrooge kept saying it didn’t add up..or, rather, it did.
Somebody came by my house selling solar with the message that the new and improved tech allowed had pushed homes in my neighborhood into the reasonable payback range. I think I believe that, but he tried to sell me even though I have a tree shading my roof.
I worked as a researcher at SERI and then NREL for nearly thirty years. I worked developing PV. Lots of folks were involved in economic analysis. In the eighties and nineties that analysis showed that a major government investment would be required to drive down the cost and make PV cost effective. The U.S. declined to make that investment. The Chinese went ahead and followed the roadmap.
I am retired now. I have a modest three bedroom ranch on a marginal lot because of heavy tree shadowing. I went and put a 10 KW system on my roof sighted as best I could. In the summer it pays my bill. In the winter not so much although it makes a major contribution. Was it cost effective? Probably not. But there is more to this decision than dollars and cents. Having built an entire career from the technology I felt a particular imperative to support it by adopting it. There is the environmental element many consider worth a premium.
We are headed towards a model where instead of relying on the grid and the grace of the power companies you can have your own storage bank in the form of an EV. Two way charging will allow you to use the grid when the rates are low and run your home from the EV during power outages and peak hours. Smart charging stations will do all the calculations. But we aren’t there yet. The Nissan Leaf and maybe the Ford lightning are the only options at this point. You can look at Tesla but you can’t drive a power wall and they don’t seem all that interested in integration. In the meantime the power companies are passive aggressively doing all they can to discourage adoption with pointless fees and delays.
Oh and my advise, don’t wait for Perovskites. Their primary problem is long term stability. All the cost analysis of PV depends on a long lifetime. Without that it doesn’t really matter what sort of performance you are able to squeeze out of a sample in the lab. Don’t believe the PR. There is a ton of research money, probably the only really sizable chunk going to this area. Mostly of what is generated are press releases. Stick with high quality crystalline Si. At least for the next twenty years I should think.

[ A superb comment. I am grateful. ]
SW
Thank you for your comment. Every time I run across one of these gems, it makes me feel good about what Dan did, now Joel does, and what I attempt on Angry Bear. Our readers are quite competent. I am working on expanding our numbers and content variety.
I like the idea of competing with the Grid. Could they impose a fee later on to recoup lost inputs? It would be looked upon as a critical resource which we could need in the future. Why go 100% self-sustaining?
My solar panel concerns are the politics first. From reading other comments, I have learned from them, the electric company (Electric District #3) drags their feet in approving the installation. The result being you may lose the loan and the excellent interest rate you worked to acquire.
Efficiency of the panels appears to be low and at 22-23% at best. The efficiency also appears to deteriorate at ~1% of the total output per year (this does not mean going from 22% to 21%). Granted this is a small loss. I am out in the desert where the sun shines most of the time. I would catch sun on both sides of my house as it faces north and south and even with two story homes on each side. It is 8:30 AM and the sun is already on the roof.
Then do we need a battery for storage?
We are in our seventies. At our age, does this make sense when our costs are low. Low because we have good efficiency already and use the thermostat wisely. At 105+, I could put it at 80 degrees inside and feel refreshed. Not doing laps here. I am at the border line from my perspective.
My neighbors have issues with the coolness of their two-story homes with two thermostats. I tend to think it is inefficient air flow as their insulation is no different than mine.
Thank you for your thoughts.

[ Hot air rises; you are of course correct. ]
Two way charging and using an EV as your storage does not mean that you are not invested in the grid. You still use the grid to make up any shortfalls in generation. But because of the smart nature of the charging system you don’t have to pay peak hour charges when you do. This is a win-win because long term this strategy saves the power company money. Their generation capacity needs to be based on peak demand. The more customers get their electricity in off peak hours the less there is a need to build out generation capacity. The smart charging system empowers the home owner not the utility. We are still committed to supporting the grid. We just don’t want to be at its mercy.
SW:
You just reminded me of something I was going to do with your initial comment.
SW:
A change of industries unless you were working with sustainable energy. This appears to be a part of your expertise. And you moved from the desert to the mountains. I am guessing.
We have a well-insulated 3-bedroom ranch. I watch the thermostat and adjust as needed. Our electric bill is low compared to many others around my wife and I. It appears we have a somewhat energy efficient house on a city-lot. Gonna eliminate the natural gas stove and go for induction. Don’t know about solar yet. Working with a 10-year window. Plenty of sun though. It appears we can get by on an average ~$110 per month for electricity. Less in the Winter and more in the Summer.

‘Hurting for water’: Hawaii resorts worsen Maui’s water shortage
By Christine Hitt
Popular among visitors to Hawaii, the hotels and resorts lining the South Maui beaches in Kihei and Wailea are lush and green, with many pools, water slides and fountains. But this is all a facade.
The coastline is actually dry, receiving less than 10 inches of water per year. It gets the majority of its water from Central Maui — the area of Kahului and around Wailuku — where residents are sometimes urged to conserve.
“The fact is that the people where the water originates are hurting for water,” Lucienne de Naie, chairperson for Sierra Club Maui Group, told SFGATE. “There are definitely shortages of water from overtourism, and those shortages of water are impacting an area we call Na Wai Eha.” …
