Solar panels lifespan: how long do they last?

Normally, a PV system is guaranteed for 25 years of "useful life": This longevity is not comparable to any other power generator, neither solar thermal system, which has a lifespan of 15 years. A long lifespan allows the system to pay for itself, both in terms of costs and carbon footprint, by supporting a virtuous circle of clean and sustainable energy generation .

How long do solar panels last?

Most reputable manufacturers offer production warranties for 25 years or more. The average break even point for solar panel energy savings occurs six to 10 years after installation. If the panels continue to produce at a high level for another 15 years after that, you will end up saving thousands of dollars during the solar panels’ lifespan.

How long do PV panels last?

However, the energy used during the manufacture of the PV panels is far less than they will generate through their lifetime. Even under UK levels of sunshine, a PV array will pay back this ’embodied energy’ in less than three years. After that, the panels deliver the full carbon saving per year estimated above.

There's a huge seasonal variation in how much of your power solar panels can provide. Read our buying advice for solar panels to see how much of your power solar panels could generate in summer.

Will solar panels generate enough electricity year-round?

Whether they'll generate enough electricity for your home year-round will depend on: if your solar panel system works in a power cut. It may be more realistic to think about whether you can be self-sufficient for the brighter parts of the year, and then top up your energy use from the grid at other times.

What happens to PV panels at the end of their life?

What happens to them at the end of their lifetime. It’s important to keep these issues in context. All electronic equipment leads to similar concerns, and whereas many electrical goods are only in use for a few years, most PV panels are expected to last for at least 30 years.
