How long does a solar photovoltaic system last?

Solar photovoltaic (PV) systems, as a mature technology with life expectancy of 20–30 years, are semiconductor devices that convert sunlight into DC electricity through the transfer of electrons.

How long does a PV module last?

The estimated operational lifespan of a PV module is about 30-35 years, although some may produce power much longer. While few systems are entering the waste stream right now, more systems will come to the end of their useful life in the next few decades.

What is end-of-life management for photovoltaics?

End-of-life management for photovoltaics (PV) refers to the processes that occur when solar panels and all other components are retired from operation. There are millions of solar installations connected to the grid in the United States, which means there are hundreds of millions of PV panels in use.

Why should you invest in a solar PV system?

SETO funds research to develop new materials and designs that can make PV products longer-lasting, less energy-intensive to produce, easier to recycle, and even less polluting at the end of life. New practices can improve understanding of environmental impacts to prevent unintended pollution or human health effects.

Can PV modules be recycled?

NREL published the first assessment of worldwide efforts to recycle PV modules and identified the best ways to manage disposal. The researchers investigated lessons learned from IEA-PVPS to help inform manufacturers and other stakeholders about recycling requirements for PV hardware and efforts to design reusable modules and other equipment.

Should I upgrade my solar panels before the warranty expires?

While weather damage and installation errors cause most end-of-life issues now, some consumers and plant operators may choose to upgrade their panels before the warranty period expires or to take advantage of technological improvements.
