How to Recycle Your Old Broken Solar Panels

How to Recycle Your Old Broken Solar Panels

Opening up your home or business to solar power is an excellent way to lower your energy costs and reduce your carbon footprint. However, solar panels don’t last forever. After several years, they start producing less electricity and eventually need replacement. But what should you do with those broken or degraded panels taking up space? Don’t send them to the landfill! With some effort, you can recycle solar panels and keep their toxic materials out of the environment. This guide will walk you through the solar panel recycling process from start to finish.

Why Recycle Solar Panels?

Solar panels contain valuable materials like aluminum, copper, and silicon that can be reused to manufacture new products. Proper solar panel recycling allows these scarce resources to re-enter the supply chain. Recycling also prevents hazardous solar panel components like lead and cadmium from leaching out in landfills. By responsibly recycling end-of-life solar modules, we conserve natural resources and protect the planet. Here are some key benefits of solar panel recycling:

  • Conserves scarce resources – Recovering aluminum, glass, and semiconductor materials reduces the need for new resource extraction.

  • Protects the environment – Recycling prevents toxic substances in solar panels from contaminating soil and waterways.

  • Saves landfill space – Diverting solar waste from landfills extends their useful lifetime.

  • Prevents pollution – Recycling prevents the release of toxic fumes and dust that occur when solar panels are incinerated or crushed.

  • Generates income – Salvaging valuable copper and aluminum creates recycling revenue.

Clearly, properly recycling obsolete solar panels has financial, environmental, and social benefits.

Laws and Regulations Around Solar Panel Recycling

With the solar industry booming, governments around the world are creating laws and regulations around the disposal of end-of-life photovoltaic modules. The main goal is to encourage producers and consumers to recycle retired solar panels instead of tossing them in the trash. Here are some key regulations guiding solar panel recycling:

  • The WEEE Directive in Europe requires PV manufacturers to finance the takeback and recycling of solar panels.

  • Japan’s Act on Promotion of Recycling of Small Waste Electrical and Electronic Equipment mandates the recycling of end-of-life solar panels.

  • The National Programme for Management of End-of-Life Photovoltaic Panels provides guidance for PV recycling in France.

  • India is developing a formal e-waste management system for the collection and recycling of obsolete solar panels.

  • US states like California, Washington, and North Carolina have extended producer responsibility laws making solar manufacturers responsible for panel recycling.

These regulations demonstrate that governments consider solar panel disposal an urgent environmental issue. By law, producers must enable the recovery of valuable resources from PV waste. Consumers also have a responsibility to dispose of solar panels properly at their end-of-life.

Solar Panel Recycling Process

Recycling broken solar panels is a multi-step process involving disassembly, shredding, sorting, and purification. Professional solar panel recyclers use the following general recycling methodology:

1. Collection and Transportation

The logistics of gathering up and moving bulky, fragile solar panels is a key part of the recycling process. Installers, waste haulers, recyclers, and consumers need to coordinate solar panel collection and transportation to the recycling facility, adhering to any applicable regulations.

2. Dismantling and Sorting

At the recycling plant, panels get manually dismantled into their main components. Workers remove the aluminum frames, junction boxes, cables, and connectors. The frameless PV laminates move on for shredding and sorting.

3. Shredding and Size Reduction

Shredders break down the panel laminates into thumbnail-sized pieces. This allows for the separation of glass, semiconductor materials, and polymers.

4. Material Recovery

After shredding, solar panel pieces pass through sorting systems that recover aluminum, copper, and low-grade plastics. Advanced optical sorters isolate silicon and other semiconductors for purification.

5. Purification

The final step is purifying recovered materials like silicon, silver, and copper to high grades usable for new solar panel manufacturing. This recovers scarce resources and closes the loop on solar panel recycling.

While exact methods vary between recyclers, this outlines the typical end-to-end solar panel recycling process. The complexity demonstrates why consumers should leave this work to accredited recycling professionals.

Finding a Solar Panel Recycling Company

Searching online for “solar panel recycling near me” is a good place to start your search. Look for an established company with solar panel recycling expertise. Here are key factors to consider when choosing a solar panel recycling partner:

  • Proper certifications – Look for NAID, R2, and e-Stewards certifications which indicate responsible recycling practices.

  • Recycling rates – Ask about how much material they recover – the best recyclers can salvage over 90% of a solar panel’s components.

  • Outlet for materials – Inquire where they send recovered materials – ideally they have long-term arrangements with solar manufacturers to reuse materials.

  • Safety record – Check for any environmental violations that could indicate unsafe handling procedures.

  • References – Talk to past clients to understand their experience with the recycler. Were they responsive, affordable, and transparent?

Take the time to thoroughly vet several solar recycling firms before you decide. A reputable, certified recycler will provide the best service while keeping your project on budget.

Preparing Your Old Solar Panels for Recycling

Once you’ve selected a solar panel recycling partner, you need to properly package and transport your obsolete PV modules to their facility. Here are some tips for preparing old solar panels for recycling:

  • Wear sturdy gloves when handling solar panels to avoid lacerations from broken glass and sharp aluminum.

  • Remove loose debris, bird droppings, or soil from solar panel surfaces before packaging.

  • Stack panels vertically on their short edge and secure them to a pallet. This prevents them from falling over and breaking further.

  • Pack panels tightly into a sturdy wooden crate or metal shipping container with adequate padding to prevent shifting.

  • Label crates clearly as “Used Solar Panels for Recycling” along with your name, company, and contact information.

  • Hire experienced hazardous materials shippers to transport your properly packaged panels to the recycling center.

With some protective gear and proper packaging, you can ensure your old solar panels survive the journey to reclamation without breaking further or harming anyone.

Cost of Recycling Solar Panels

While it costs money to properly recycle solar panels, the expense is far less than the value recovered from salvaged materials and the avoided costs of hazardous waste disposal. For consumers, solar panel recycling costs range from $20-$25 per standard 60-cell panel on the low end to $1-$2 per pound on the high end, plus transportation fees.bulk discounts from recycling firms. This reasonable price makes solar panel recycling accessible for homeowners and businesses. And some manufacturers and installers provide free takeback programs for their old panels which reduces costs further. Given the benefits, solar panel recycling delivers excellent value.


Responsibly recycling end-of-life solar panels conserves resources, protects the environment, and creates jobs. With national solar panel waste volumes projected to reach 80 metric kilotons by 2050, recycling will only grow more crucial. Now that you understand the solar panel recycling process from collection to purification, you can make sure your old panels get properly recycled. Partner with a reputable solar panel recycling company to keep valuable resources circulating in the economy and prevent toxic materials from harming the environment. Recycling broken solar equipment may take some time and money, but it’s one of the wisest energy investments you can make for the future.
