Solar panels can be a great way to use the sun to supply your home with most or all of the power it needs. However, if you are in the market for solar panels, it is important to understand that solar panels do not last forever. In fact, they slowly degrade year after year after exposure to the sun and elements, and slowly lose some of their efficiency, until eventually, they need to be replaced. This may leave you wondering how long can solar panels last? Read on to the answer to this question and any others you may have.
How Long Do Solar Panels Last?
There are many factors that determine how long solar panels may last. As such, the solar panels that you select may last a little longer or a little shorter than the numbers listed. However, as a general rule of thumb, most solar panels that are made these days last about 25 to 30 years. If you are looking to purchase solar panels, pay close attention to the tier of the panels. There are three tiers; tier one, tier two and tier three. Tier one panels degrade the least amount from year to year, while tier three panels degrade more quickly.
Why Does Warranty Matter When It Comes to Solar Panel Lifespan?
When you are considering purchasing solar panels, you should always pay attention to the warranty to the panels come with. Most reputable solar panel manufacturers will warranty their panels for 20 to 25 years. This gives you peace of mind that your solar panels will last for at least the length of the warranty, and if they do not, the manufacturer will replace them. This is one of the best guarantees you have for how long you can count on your solar panels lasting.
What Factors Affect How Long Solar Panels Last?
As was mentioned above, there are many factors that directly affect how long your solar panels will last. This includes the tier of the panels you buy, how much sun exposure the panel gets, the weather elements the panel is exposed to and if the panels are properly installed. The mounting position and the average temperature where you live can also have an affect on how long solar panels last. As such, it is important to talk to a solar panel installation company about which panels may be right for your home, based on the conditions where you live.
Can You Do Anything to Help Your Solar Panels Last Longer?
While you cannot control every element that affects the lifespan of your solar panels, there are a few things you can do to help ensure your solar panels last. The first thing you can do is ensure you hire licensed or certified installers to properly install your solar panels. Next, ensure you are keeping your panels maintained. Solar panels require little maintenance, but if you fail to perform this minimal maintenance, the panel’s lifespan can suffer. Lastly, take the time to regularly clean your solar panels. Solar panels should be cleaned about once every six months to remove dust, dirt, and residue that can negatively affect the performance of your solar panels.
Prior to deciding whether solar panels are for you, you may have many questions, including how long can solar panels last. Getting answers to all of the questions that you may have is the best way to determine if installing solar panels on your home may be right for you, and to learn how to properly care for these panels if you do decide to install them on your home.
