What landowners should know about panel recycling, site restoration and protecting their land over the long term
For many landowners, hosting solar projects can create a viable income stream that may help preserve farmland for future generations. But just like any other piece of infrastructure on the farm, solar equipment will not last forever.
Most modern solar panels are designed to operate for roughly 25 to 30 years, prompting the inevitable question: What happens to solar panels when they reach the end of their productive life?
How Does Solar Panel Recycling Work?
Solar panels contain valuable materials that can often be recovered and reused.
Recycling technology for solar panels continues to evolve as more panels are installed across the country. Today’s processes can separate and reclaim a large portion of a panel’s materials, and researchers and private companies are working to improve both efficiency and the economics of the process.
Today, many panels are sent to specialized recycling facilities, often glass or electronics plants, where valuable materials like glass, aluminum and metals are recovered. These materials can have value, though the economics of recycling vary by project, location and market conditions.
Material Recovery
What layers inside a solar panel can be recovered? Panels are made of multiple tightly bonded layers, which makes dismantling more complex than simply separating raw materials. Most modern crystalline silicon panels are about 80% recyclable by weight, depending on the method used.
Key components include:
- Glass (70 to 75% of panel weight): Recovered and reused in new glass manufacturing or construction materials; glass makes up the largest share of recoverable material
- Aluminum frames: Recycled into new aluminum products
- Polymers: More difficult to recover and often used for energy recovery rather than material ruse
- Silicon cells: Advanced processes can recover high-purity silicon, though large-scale reuse is still developing
- Metal wiring (copper, silver): High-value metals can be recovered, with improving recovery methods over time
Land Stewardship and Lease Negotiations
For many farm families, the decision to host a renewable energy project is often about both land stewardship and economics. Solar panels may operate over multiple decades, but the land itself is expected to support future generations. That makes planning for the end of a project just as important as planning for the beginning.
Recycling and decommissioning provisions are one way landowners can help ensure their property is returned to a usable condition once a solar project reaches the end of its productive life. Clear expectations in lease agreements can help define who is responsible for removing equipment, how materials will be handled and what protections are in place if a project changes ownership over time.
Who is Responsible for Solar Panel Recycling?
Decommissioning responsibilities are typically assigned to the project developer or future project owner through the lease agreement and required decommissioning plan. These plans generally outline the full scope of removal activities, including dismantling panels and racking systems, removing electrical equipment and restoring the land through grading and reseeding.
One potential pitfall for landowners is being sure that the financial assurance mechanisms, such as bonds, escrow accounts or letters of credit, are included in the agreement. These safeguards help ensure funds remain available for equipment removal and site restoration, even if the project owner changes or the company operating the project ceases operations.
Key Takeaways
When you first enter into a solar lease agreement, you may not immediately be thinking about the panels’ end of life many years down the road. Keeping it in mind early can help avoid costly surprises while safeguarding your land and lease. As you think through a potential solar agreement, a few key points are worth keeping in mind:
- Understanding recycling options is part of responsible stewardship for both your land and the environment
- Solar panels contain substantial recyclable material, though recycling access and infrastructure continue to evolve
- Decommissioning and recycling provisions should be clearly defined and understood by all parties in any lease agreement
For REFA members, this is not something you have to sort through on your own. Through its non-legal lease review service, REFA works alongside landowners to help them understand how provisions like decommissioning, financial assurances and end-of-life planning may affect their land, their operation and their long-term plans.
