In recent years,solar panelusage ofThe volume has increased dramatically, bringing a series of benefits to homeowners who take advantage of the sun’s rays: Reduce energy costs, increase home value and reduce carbon footprint.But the solar panel Early stageprice也very high。investing heavilyBefore buying solar panels, homeowners naturally want to know how many years they can use them.
Below we'll answer the question of the longevity of solar panels, some of the factors that affect their longevity, and how to make them last longer to capture the most light for your money.
To answer the question of the lifetime of a solar panel, we should first define degradation.according toNational Renewable Energy Laboratory'sstatement, degradation is 'The solar panel output decreases over time'
Degradation is a key factor affecting the lifespan of solar panels.NRELData shows that the degradation rate of solar panels is about 0.5% per year.Therefore, after 20 years of use, the solar panels will be able to generate about 90% of the new electricity.
Based on this information, solar panel manufacturers typically provide approximately25 years or morewarranty period。For newer or well-built systems, the panels can last up to 30 years.
There are various factors that can increase the productivity of solar panels and extend or shorten their lifespan.Some of these factors include:
As with most things,you installof solar panelsquality, materials andtypewill affect their working effect and service life.While lower-quality materials may be more affordable, they may also degrade faster.
Extreme weather can shorten the life of solar panels.If you live in an area with cold, heavy rain, snow, and hail, you may find that your solar panels degrade faster.
How the panels are installed - and the racking system they are installed in - affects their degradation rate.
Just like any other valuable thing you buy, solar panels can last longer with good maintenance.If the panels are dirty, have debris on them, or are not regularly maintained, they may degrade faster.

As you can see, some factors that cause solar panel degradation are controllable, while others are not.Fortunately, there are many steps you can take to get the most out of your solar panel.
One of the ways to extend the life of your solar panels is to work with a trusted supplier.First and foremost, a trusted supplier will ensure you get quality panels made from quality materials.Also, a good supplier will make sure the panels are installed correctly.The solar provider will provide regular maintenance checks to make sure everything is in order.
There are also things you can do yourself to extend the life of your solar panels.For example, be sure to remove branches, snow, and other debris that could end up on the solar panel.Keeping a panel clean is one way to extend its lifespan.
A good solar panel lasts 20 to 30 years, but doesn't necessarily have a date when you should replace it right away.More importantly, pay attention to their productivity.If your solar panels are still in good condition and producing enough power, they probably don't need to be replaced.On the other hand, if you find that your electricity bills are going up because your solar panels are no longer functioning, it may be time to replace them
