Your Guide to Solar Panel Lifespan

How many years can you get out of your solar panel system? Click here to explore the average solar panel lifespan and why they're worth the investment!

Did you know that the solar panel lifespan is 30-35 years?

Even though there are cloudy days when your panel won’t collect that much energy, it will still last a very long time. When handing out thousands of dollars on any project, you must consider all factors before finalizing your purchase.

The lifespan of a solar panel depends on a variety of factors. By understanding the solar panel lifespan and how to take care of your panels, they should provide you with many years of clean energy.

Perhaps you are asking how long solar panels last. If you have this in mind, check out this article for the answers.

Variables That Affect Solar Panel Lifespan

Solar panels are long-lasting, energy-efficient appliances that can last decades without needing replacements. But, several variables can affect their lifespan. These may include the installation process, environmental conditions, and component quality.

Keeping these factors in mind when researching solar panel options can ensure that you are going to experience the benefits of investing in solar panels.


Proper installation is key to ensuring the greatest longevity of your solar panel system. A solar panel contractor who knows local weather conditions and building codes should do the installation.

Furthermore, a good contractor will install the correct mix of solar panels, batteries, and mounting equipment tailored to your location, roof size, and energy needs.

The installer should provide you with a warranty for parts and labor that covers any malfunctioning equipment. Finally, make sure of the evaluation of your solar system. Also, it should pass inspection if required by your local government.

Environmental Conditions

Environmental conditions play a big role in solar panel lifecycle. Temperature fluctuations, wind, humidity, and rain can especially affect roof solar panels. Direct sunlight can cause thermal expansion, which can shorten a solar panel’s lifespan.

Damage can occur from high temperatures and intense sunlight, causing the solar panel to overheat. Rain and fog can cause the solar panel to corrode or its components to fail due to water infiltration.

High wind speeds can cause the solar panel to shake or vibrate, leading to mechanical failure or components cracking over time. Finally, dust, dirt, and pollination can accumulate on the surface of the solar panel and reduce its efficiency.

It is also recommended to do regular site surveys to assess how well the panels are performing in their current environment. Take into account these factors that can affect the solar panel lifespan.

Component Quality

The quality of the components used to build the solar panel is one of the biggest variables that will impact its lifespan. Poor-quality components can lead to excessive wear, frequent malfunctions, and greater power loss.

Better components will be more reliable and last longer than those of lesser quality. Quality solar panels will also make use of more durable materials, helping to protect the panel from the sun’s harsh UV rays.

You must make a careful selection of components to ensure that you get the most out of your investment. This will result in panels that will run at peak efficiency throughout their lifespan.

Lengthening Solar Panel Lifespan

The quality of the materials used in manufacturing them determines how long solar panels last. But there are also some great tips that you can use to lengthen the lifespan of your solar panels. 

Take into account these few factors to help ensure optimal performance and extend the lifespan of your solar panels. These include installing solar panels in the correct area as well as proper covering of the system.

Moreover, you must keep it clean. Solar panel care is important, so do not overlook these ways to get the best from your solar panel.

Install Solar Panels in an Area With Minimal Weather Damage

Install solar panels in areas with minimal weather damage to ensure maximum lifespan. Avoid areas that experience high levels of rainfall and thunderstorms should, if possible.

Install the panels on a stable slope that allows water to easily flow off the solar panels. It is also helpful to install solar panels in a shaded area to cut the possibility of overheating.

Taking these steps can help to make sure the solar panel system performs efficiently and optimally and maximize its lifespan.

Cover Your Panels During Intense Weather Conditions

To extend the lifespan of your solar panels, it is important to cover them during intense weather conditions. This will prevent them from suffering damage from high winds, hail, or heavy precipitation.

It is best to use weather-resistant material such as a customized tarp or a sheet to fit your panel. Furthermore, keep your solar panels dry to prevent them from becoming oxidized.

Covering your solar panel during intense weather conditions will make sure that they produce optimal amounts of solar power for a long period.

Keep It Clean

Keeping your solar panel clean is essential to lengthen its lifespan. Brush off dirt and debris from the surface of the panels to prevent any dirt or dust from gathering and blocking sunlight.

Washing the panels with soap and water regularly will help keep them clean and prevent excess dust buildup. Regularly check the panels, especially after storms, to make sure they’re not covered in dirt, mud, leaves, or other debris. If any panels have residue that won’t come out easily, seek professional help to clean them properly. 

This is an essential part of your solar panel maintenance. By keeping it clean, you’re taking steps to ensure a longer lifespan for it and a better return on your energy investments.

Take Care of Your Solar Panel to Increase Its Lifespan

Take into account all the variables that may affect the lifespan of your solar panel, and that includes installation, environmental conditions, and component quality. Also, you have to take note of how you can lengthen the solar panel lifespan.

One of the ways is to include installing solar panels in an area with minimal weather damage. Moreover, cover your panels during intense weather conditions, and keep them clean.
