A solar panel can last for 25 to 30 years maximum. But, then how long do solar panel batteries last? Generally it completes a long span of 25-30 years and then head towards replacement. But, if you want them work for you longer, replace them after 20-22 years and get the best service. How Long Do Solar Panels Last ?

It also depends on the type of usage you are doing for that particular panel that makes it durable for more years. No power gauge or device can last forever, but it depends on one’s usage that makes it great last for long span. 

This article speaks volume about the longevity of the solar panels. But, before we conclude anything about-How Long Do Solar Panels Last? You need to make sure, about some other points which will help you under about the subject in depth. 

Do You Think Solar Panels Wear Out?

If this is your question, you need to make sure about the quality you have invested in.

How Long Do Solar Panels Last?

Then how do you know whether the condition is good or bad? It is from the reduction process in the solar panel output that will speak in details about the condition of the solar panels. 

In a research conducted by NREL, it has been stated that about 0.5% per year is the rate of reduction in the solar panels. This rate goes up and down compared to the hotter climates and for rooftop system. 

What Is The Lifespan Of Solar Panels?

Before you make sure about what is the lifespan of the solar panels, know about why do solar panels degrade? The reasons can be many but here we will discuss about the crucial ones. 

Solar panel lasts for 25-30 years in general. And over the time they degrade due to weather condition, excess usage, overheating of the panels then and now. All it may mean that the production of energy has declined significantly. But, mostly these solar panels are extremely durable.  

  • Solar panels, also coined as photovoltaic or PV panels may last upto 25-32 years
  • Those which were installed in 1980 is still working fine with an expected capacity
  • But, how often do solar panels need to be replaced? Relax with the thought that after 30-32 years you can replace the panels

As long as these PV panels are maintained from time to time, they keep giving a better service without any hiccups.

Thus, a monthly and a quarterly maintenance or checkups of the panels ascertain that the panels are working at its best speed. Sometimes annual maintenance may also ascertain the working better.

How Long Can Solar Panels Last Without Sun?

If you think about the fact how long can solar panels last without sun, and then be sure that the solar panels utilize the direct daylight energy completely so that they work and produce electricity fantastically during the nighttime. This is very common when it comes to discussion on solar panels. 

Basically, solar panels comprises of materials like the silicon which creates the electric current when it comes in contact with the natural daylight. 

  • Net metering 
  • Solar storage technology

These are the two methods that can help solar panels to capture the day light and use it during the night time and cloudy days. 

Here Are The Tips To Make Your Home Solar Panels Last Longer-

You must clean your solar panels frequently or in intervals to keep it smoothly working towards a long span. Apart from this you may sign up for a professional service. You must ensure retaining the optimal production of the solar panels.  

  • Keep the solar panels well maintained with monthly/quarterly/annual maintenance to make it last for longer days
  • Keep check on the performance warranty and the equipment warranty of the racking and wiring and solar batteries 
  • Keep note of the solar panel age, weather conditions, service history, solar panel monitoring, geography of a region, rate of degradation, inverters

How Much Will The Solar Panels Take In Order To Pay For Them?

Unless it starts to wear out in conditions, there is no need to replace them. If you see the amount of capacity your panels are supposed to produce are going down, it means it is time for you to replace them. 

How Long Do Solar Panels Last?

People might think if solar panels really need to be maintained on regular basis. The answer is no, they require monthly, quarterly and yearly maintainenece of the wiring and the inverters with the batteries to keep them working for longer period of time. 

  • Solar panels or PV panels require very less maintainenece support
  • Keep them at safe distance from harsh weather conditions
  • Panel maintenance and cleaning is not estimated with panel warranties 
  • Integrate a solar monitoring panel system to keep the panels working better 

Generally keep the solar panels perform solar panel cleaning between two to four times per year for better solar health.
