When considering installing photovoltaic solar panels or if you already have them, knowing the lifespan of a solar panel is important in order to estimate the profitability of its installation. With current technology, a solar panel lasts on average between 30 and 40 years!
A solar installation is composed of photovoltaic solar panels And of a inverter which transforms the direct current from the panels into alternating current. Depending on your needs and the regional context, you may also have a home storage battery that will store your solar energy.
In recent years, numerous developments have emerged in the field of photovoltaics. Photovoltaic solar panels are less and less expensive but are also more and more resistant and efficient.
If your solar panels are properly maintained, the lifespan of your photovoltaic solar panels can be up to up to 30 or even 40 years.
Their lifespan therefore extends well beyond their payback period, which is currently 5 to 10 years.

The average lifespan of an inverter is between 8 and 12 years. It is therefore lower than that of a photovoltaic panel. Note that the warranty for an inverter is generally 5 years but warranty extensions exist.
You will have understood it, so you will have to Change your inverter approximately every 10 years. The price of an inverter is around €1,500, which is still reasonable.
A storage battery is interesting to increase your self-consumption.
The lifespan of a storage battery depends on the number of charge and discharge cycles. Storage batteries go between 500 and 5,000 cycles, which corresponds to a lifespan of about 10 years.

Some external elements can impact the lifespan of solar panels:
To find out if a solar panel needs to be replaced, simply monitor your production regularly.
With your monitoring application, it is easy to observe your solar production. So you can easily identify a problem.
