About How long is the service life of solar power generation
The estimated operational lifespan of a PV module is about 30-35 years, although some may produce power much longer.
The estimated operational lifespan of a PV module is about 30-35 years, although some may produce power much longer.
While properly cared for panels can last up to 50 years, the accepted industry estimation of how long solar panels last is 25–30 years.
Long story short, a solar panel’s lifespan is about 25 to 30 years. Its performance naturally declines over time, eventually rendering its “useful life” complete.
The typical lifetime of solar panels is around 25 to 30 years, with proper maintenance and high-quality materials playing a crucial role in their longevity.
As the photovoltaic (PV) industry continues to evolve, advancements in How long is the service life of solar power generation 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 is the service life of solar power generation]
How long do solar panels last?
Most PV systems are young—approximately 70% of solar energy systems in existence have been installed since 2017. The estimated operational lifespan of a PV module is about 30-35 years, although some may produce power much longer.
Do solar panels stop working after 25 years?
After 25 years, solar panels will be less efficient and produce less power. This doesn’t mean your solar panels will stop working, but they may be less effective at powering your home and lowering your energy savings. When panels degrade to the point where they no longer produce power, they’re ready to be recycled.
How much energy does a solar panel produce a year?
This decrease in efficiency, known as degradation, typically occurs at a rate of about 0.5% to 1% annually. Consequently, after 25 years, you can expect solar panels to produce approximately 75% to 87.5% of the power output they initially provided when they were new.
Do solar panels need a lot of maintenance?
Solar panels require little to no daily maintenance. Rainfall keeps the panels’ surface clean most of the time. However, heavier debris, such as snow or broken tree branches, can sometimes accumulate. This debris will block your panels’ ability to absorb sunlight, so it’s important to clear it off.
How much do solar panels deteriorate a year?
The National Renewable Energy Laboratory (NREL) has been tracking degradation rates for the last several years as part of its Photovoltaic (PV) Lifetime Project. NREL’s findings indicate that solar panels have an average degradation rate of 0.5% per year.
What is a solar panel warranty?
Solar panel warranties are key to maximizing the lifespan of your solar panel system. In addition to your equipment warranty, which certifies against manufacturing defects, your performance (AKA power) warranty guarantees that your solar panels maintain a certain percentage of their original output each year.
