On average, well-built solar panels last between 20 and 30 years before their power output begins to decline significantly.
For modules built today, it is probably 30 years.
The most dependable part of photovoltaic (PV) power systems are PV modules. Under normal operating conditions, the PV module will continue to function properly for 25 years.
With an average lifetime of 20 to 30 years for photovoltaic panels, a massive volume of PV panel waste will emerge shortly (Kim and Jeong, 2016; McDonald and Pearce, 2010).
As the photovoltaic (PV) industry continues to evolve, advancements in How long does it take for solar photovoltaic panels to become obsolete have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.

6 FAQs about [How long does it take for solar photovoltaic panels to become obsolete ]
How long do solar panels last?
And because solar panels contain toxic materials like lead that can leach out as they break down, landfilling also creates new environmental hazards. Most solar manufacturers claim their panels will last for about 25 years, and the world didn’t start deploying solar widely until the early 2000s.
Are obsolete photovoltaic panels sustainable?
While the sustainable management of obsolete photovoltaic panels would be influenced by the lack of accurate data on the waste flow of each PV consumer country, only about 16% of studies related to specific countries have attempted to estimate their EoL PV waste streams.
Is EoL photovoltaic waste a problem in the future?
An enormous amount of obsolete solar PV modules will be added to the waste stream in the near future. Hence, the EoL photovoltaic waste stream could cause an appalling problem in the future if a holistic management strategy is not considered.
Should solar panels be repurposed at the end of life?
The report, End-of-Life Management: Solar Photovoltaic Panels, is the first-ever projection of PV panel waste volumes to 2050 and highlights that recycling or repurposing solar PV panels at the end of their roughly 30-year lifetime can unlock a large stock of raw materials and other valuable components.
How often do solar panels go bad?
Solar panel technology has come a long way over the past few decades, but we're far from creating a perfect solar cell. Given these inefficiencies, solar panel manufacturers expect a degradation rate of about 0.5% a year, Pearce said, and their warranties will cover any panels that fail to meet those expectations. However, this is rare.
How long do PV panels last?
The average panel lifetime for the PV modules was presumed three decades on average for both scenarios with a probability of 99.99% loss at 40 years after installation (IRENA: Stephanie Weckend, 2016). The amount of total obsolete PV panels will surge substantially over the next years which necessitates a long-winded plan. Fig. 2.
