Solar Panel Lifespan: How Long Do Solar Panels Last?

Solar panels have come a long way in terms of durability and efficiency, but there is still some uncertainty around how long they will last. We will look at the different types of warranties available and help you with a range of tips to keep your solar panels in good condition.

Solar panels are designed to last for decades. The average lifespan of a solar panel is around 25 years, but its performance will degrade over time. The lifespan varies on the quality of the panels and how they are maintained. Solar panels that are not used regularly can last for up to 40 years.

With proper maintenance and testing, solar panels can last decades longer than their warranty. Let’s discuss what factors affect the lifespan and some great tips to extend the life of your solar panels.

How Long Do Solar Panels Last on Average?

Solar panels have an industry-standard life span of around 25 years with regular use. However, this number can vary depending on the brand, quality of installation, and other factors.

The reason they last this long is that they are made with durable materials. The solar cells in solar panels can withstand a lot of wear and tear, as well as all types of weather conditions.

Your Solar panel system may start losing efficiency after 15 years or so due to natural degradation over time. That’s why it’s important that your system is installed correctly and maintained well throughout its lifespan.

Solar panels that are not used regularly can last for up to 40 years. This is because they are not subjected to as much wear and tear.

Factors that Affect Solar Panel Lifespan

The lifespan of solar panels can be affected by a number of factors. The most common factors that affect solar panel degradation are:

  • Location – Solar panels in hot weather will degrade faster than those in cold climates due to UV rays, wind, and rain.
  • Solar irradiation – The more extreme temperatures your solar panels are exposed to, the more they will degrade over time.
  • How Often They’re Used – The more often your solar panels are used, the shorter their lifespan will be. This is because they will experience more wear and tear.
  • Type of System – A standalone system usually has a shorter lifespan than those connected to the grid.
  • How Well They Were Installed – Lower quality panels can lead to a shorter lifespan and reduced efficiency over time.
  • How Much Sunlight They Receive – If your location gets less sunlight, then this could cause degradation faster than in areas that get more sun exposure.

It’s important for homeowners to understand how factors like these can impact their solar panel system lifespan. That way, they’ll know how long solar panels produce energy and can make the most informed decisions about their energy needs.

The Benefits of Having Long Lasting Solar Panels

There are a number of benefits to having solar panels that last a long time. All of them are positive for the environment and your wallet!

  • Reduced Waste – Solar panels that last longer mean less waste ending up in landfills.
  • Lower Energy Bills – The longer your solar panels last, the more money you’ll save on energy costs.
  • Increased Property Value – Having solar panels installed can increase the value of your home, but only if they’re high quality and well maintained.
  • Lower Carbon Footprint – Solar panels last longer than conventional energy sources such as coal or oil, so there’s less impact on the environment as a whole when using them for electricity generation over time.
  • Less Cost – You won’t have to replace them as often – This reduces your solar panels’ cost in the long term.

Having higher quality panels is important for peak efficiency and maximum power output. You’ll know that you’re doing your part to reduce your carbon footprint and won’t have to worry about whether or not your panels will last.

How to Extend the Lifespan of Your Solar Panels 

There are a few things you can do to make sure your solar panels last as long as possible and have peak performance. Here are some tips:

  • Keep your solar panels clean and free from dirt, debris, or even tree sap.
  • Avoid placing anything on top of the panels, as this can cause damage to their surface area over time.
  • Do not install your solar panels near trees as birds could nest on them and cause damage.
  • Get regular maintenance checks done by a professional solar panel technician.
  • Make sure you’re using high-quality products to install your system so that it lasts as long as possible without needing repairs or replacements down the road.

Good maintenance and care will help ensure your solar panels last as long as possible. By following these tips, you’ll be able to enjoy their benefits for many years to come!

Solar Panel Warranties and Their Lengths

Warranties are a big deal when it comes to solar panels. Most solar providers come with a warranty that can last up to 25 years or more, but not all companies offer such long warranties.

Some only guarantee their products for five years at most before they expire and you’ll have no recourse if anything goes wrong during that time frame!

The good news is that there are a number of companies that offer longer warranties than the standard five years. So, it’s important to do your research before you buy solar panels and make sure that you’re getting what you expect in terms of warranty length.

There are three types of warranties available for solar panels: product, workmanship, and performance. These warranties are all different, but they’re all important to know about when you’re buying solar panels because each one provides a different kind of protection for the owner.

Product Warranty

This equipment warranty is what you get from the manufacturer of solar panels. This warranty protects you against any manufacturing defects in the materials of the product. It usually lasts for a period of five to ten years.

A manufacturer’s test takes place on the solar system components such as the solar inverters and panels to ensure that they are working properly before installation begins.

Workmanship Warranty

The Workmanship Warranty is offered by the installer of your solar panels. This warranty protects you against any mistakes or defects in the installation process. It usually lasts for a period of one to five years.

Damaging materials, incorrect assembly, and wiring problems are all covered under a workmanship warranty.

Performance Warranty

The Performance Warranty is offered by the manufacturer and ensures that electricity generation will remain at a certain percentage of its original capacity over time and can be anywhere. It’s usually good for ten to twenty years.

It’s important to read the warranty carefully before you buy solar panels, as not all of them offer the same level of protection. You don’t want to be stuck with a warranty that doesn’t cover the things you need it to!

When shopping for solar panels, be sure to ask about the warranties offered by each company. That way, you’ll know what you’re getting into and can make an informed decision about which panels to buy.


Final Thoughts

There are many factors that can affect how long your solar energy system will last. Sun exposure, weather conditions, and the quality of the installation all play a role in determining the solar panel degradation rate.

To extend the life of your solar panels, you should clean them regularly, check their wiring, and inspect them for any damage.

It’s important to remember that even if your solar panels have reached the end of their lifespan, you may still be able to get reduced energy production from them.
