How Often Do Solar Panels Need to Be Replaced on Average?

It’s hard to argue with the benefits of solar panels. Not only can they potentially help save the environment, but they’re also a consistent source of power in the form of electricity.

Solar panels allow you to rely less on other energy sources. However, with technology advancing quickly, there’s a chance your solar panels are behind the times.

So you might be wondering, “How often do solar panels need to be replaced?” Keep reading to learn everything you have to know.


The Expected Lifespan of Solar Panels

Solar panels are expected to have a long operational life. The average life span of a solar panel is typically between 20 and 25 years. Yet some manufacturers claim that their solar panels last up to 33 years, while others state that their solar panels last up to 40 years.

However, while some solar panel models last a long time, most must be replaced sooner due to defects or poor installation. Solar panel efficiency generally decreases each year, about one percent annually. While solar panels do not need to be replaced regularly, maintenance should be carried out to ensure the best performance.

Generally speaking, any parts that experience wear and tear should be replaced every 5-10 years. This includes wiring and mounting hardware.

Most people probably won’t need to replace their solar panels until they have decided to upgrade to more efficient options. Since the lifespan of solar panels is upwards of 20 to 25 years, it’s safe to say that they should be replaced every two to three decades.

Factors that Can Impact the Need for Solar Panel Replacement

Solar panels are typically built to last a long time. However, several factors can influence how often solar panel replacement should be done. This includes environmental factors, weather damage, maintenance, amount of use, and installation.

Environmental factors such as high temperatures, humidity, and snow can all affect the lifespan of a solar panel. Weather damage from hail, strong winds, and lighting can also cause severe damage to the panel.

Regular maintenance to clean the panel and replace any defective components is also important. They can significantly reduce their efficiency and performance if ignored.

Furthermore, the amount of use solar panels get can also determine when they need to be replaced. Frequent use can decrease their lifespan.

Finally, improper installation can create a large amount of damage. It can decrease the lifetime of the panel.

Maintenance Strategies for Solar Panels

Regular maintenance is important to ensure optimal performance and to extend the panels’ lifespan. Cleaning and removing snow from the panels should be done at least once a year to prevent excessive buildup. This can affect the performance and reduce the lifespan.

Additionally, any problems should be identified and addressed as soon as possible. This is to prevent further damage.
