Solar Panel Durability: How to Ensure Your Panels Last a Lifetime

June 9, 2024

Solar panels have become an increasingly popular choice for individuals looking to switch to renewable energy sources. Solar panels offer a range of benefits, from reducing carbon emissions to saving money on energy bills. However, one of the concerns that people have when considering solar panels is their durability. How durable are solar panels? In this article, we will explore the answer to this question and provide you with all the information you need to make an informed decision.

What Are Solar Panels Made Of?

Before we dive into the durability of solar panels, it’s important to understand what they are made of. Most solar panels are made up of several layers of materials, including:

  • Silicon cells: These are the most important part of a solar panel as they are responsible for converting sunlight into electricity.
  • Glass: The silicon cells are typically covered by a sheet of glass to protect them from the elements.
  • Frame: The frame provides structural support and protects the panel from damage.

How Long Do Solar Panels Last?

The average lifespan of a solar panel is around 25 years. However, this can vary depending on a range of factors, such as the quality of the panel, the climate it’s in, and how well it’s maintained. In some cases, solar panels have been known to last for up to 40 years.

What Can Affect the Durability of Solar Panels?

Several factors can affect the durability of solar panels, including:

Weather Conditions

Solar panels are designed to withstand a range of weather conditions, from rain and snow to extreme heat and cold. However, exposure to severe weather conditions can cause damage to the panels over time. For example, hailstorms can cause cracks in the glass covering the silicon cells, which can impact their efficiency.


Like any other technology, solar panels require regular maintenance to ensure they continue to function at their best. This includes cleaning the solar panels to remove dirt and debris, as well as checking the frame for any signs of damage.

Quality of Materials

The quality of the materials used to make the solar panels can also impact their durability. Cheaper solar panels may be more prone to damage, and their efficiency may decrease over time.

Can Solar Panels Be Repaired?

In some cases, solar panels can be repaired if they are damaged. For example, if the glass covering the silicon cells is cracked, it may be possible to replace it. However, in other cases, the entire panel may need to be replaced.

How to Extend the Lifespan of Your Solar Panels

If you want to ensure your solar panels last as long as possible, there are several things you can do:

  • Regular maintenance: As we mentioned earlier, regular maintenance is crucial to the lifespan of your solar panels.
  • Choose high-quality materials: Investing in high-quality solar panels may cost more upfront, but it can save you money in the long run by reducing the need for repairs and replacements.
  • Install them properly: Make sure your solar panels are installed by a professional to ensure they are set up correctly and are less likely to be damaged.


So, how durable are solar panels? The answer is that they are designed to last for many years, and with proper maintenance and care, they can last even longer. Factors such as weather conditions, maintenance, and the quality of materials used can all impact their durability, so it’s important to take these into consideration when choosing and maintaining your solar panels.


Do solar panels degrade over time?

Yes, solar panels can degrade over time, but this can be slowed down with proper maintenance.

How often do I need to clean my solar panels?

It’s recommended that you clean your solar panels every 6-12 months.

Can solar panels be damaged by hail?

Yes, solar panels can be damaged by hail, especially if the hailstones are large or if the panels are older and have already sustained damage. It’s important to check your panels for damage after a hailstorm and contact a professional if you suspect any issues.

What happens if a solar panel stops working?

If a solar panel stops working, it may be due to a range of issues, such as damage to the silicon cells or a malfunctioning inverter. If you notice any issues with your solar panels, it’s important to contact a professional to diagnose and fix the problem.

How much do solar panel repairs cost?

The cost of solar panel repairs can vary depending on the extent of the damage and the type of repair needed. In some cases, simple repairs such as replacing a broken glass cover may only cost a few hundred dollars. However, more extensive repairs or replacements can cost several thousand dollars.
