How Long Do Solar Panels Last in Florida

Solar panels are a popular choice for Florida homeowners who want to save money and generate their own electricity. Many people wonder how long solar panels can last. So, how long do solar panels last in Florida?

Solar panels typically last 25-30 years in Florida. While their lifespan depends on various factors, proper planning could still enable your panels to produce power efficiently beyond this standard timeline. In this article, we’ll look at how long solar panels last and which elements affect them.


How Long Do Solar Panels Last?

You will save money the longer your solar panels are able to generate electricity. It’s good to know that the majority of home solar panels can operate for up to 25 years without noticeable degradation.

Solar panels will continue to convert solar energy even after this point. They just do so at a lower efficiency than they did when the panels were brand new. It’s rare for a panel to stop producing energy completely, but the degradation rate could be so high that you need to replace them.

 Many manufacturers also offer shorter warranties on the equipment that goes with the solar panels. It can cover damages caused by extreme weather, falling branches, and other factors.  Solar panel warranties do not include coverage for racks due to the potential damage from weather elements.

What Solar Panels Last the Longest?

The quality of a product is one of the most important factors in determining how long a solar panel will last. The solar panels on the market can be classified into three categories: 

  • Tier One 
  • Tier Two
  • Tier Three 

Tier One manufacturers are those who have produced solar panels for at least five years and have a stable financial situation. They also have high ratings for their service and product quality.

Tier One solar panels boast higher standards, producing higher production over 25 years when compared with Tier Two and Tier Three panels. Tier One cells experience degradation rates of just 0.30% per year versus Tier Two’s 0.50% degradation rates and 0.80% for Tier Three degradation rates respectively. Tier One panels may cost more upfront – typically 10%-30% more – but these costs should be recovered over time.


What Is the Solar Panel Degradation Rate?

Solar panels experience a gradual degradation in performance as they are exposed to sunlight, weather conditions, and other environmental factors. The degradation rate is the rate at which solar panels’ efficiency and output decline over time. This is usually measured as a percent of the annual power output that has been lost.

According to research conducted by the National Renewable Energy Laboratory, solar panel degradation averages 0.5% over 25 years, meaning they’ll produce around 89% of their original output.

Solar panel efficiency will gradually decline with age due to factors like sunlight exposure, temperature variations and humidity changes, mechanical stress, and quality/manufacture of materials used. Solar panels can deteriorate over time, but advances in technology have made them more reliable and durable with reduced degradation rates.  You can install these panels with confidence.


Solar Panel Lifespan: Factors That Affect It

You cannot control some factors, such as extreme weather and climate. There are still ways to increase the lifespan of your solar panel.


Solar panel Tiers reveal that quality makes an enormous impactful statement about long-term output. To get an idea of this output, check the manufacturer’s warranty to get an indication. A company offering 25 years or longer protection will likely stand behind its product for extended use.


Assure the longevity of your solar panels by choosing an experienced solar installer in Florida. Misinstallation or wiring could hasten degradation. Many top companies provide maintenance checks to monitor system operation and detect any issues before they become more severe.


Climate has a huge effect on solar panel performance and lifespan, and you should be mindful of its influence when installing panels in different regions. You must therefore remain mindful of its effect when considering efficiency and lifespan considerations for solar panel installation projects.

Solar panels tend to degrade more rapidly in warmer environments as they become more vulnerable to degradation due to heat. Furthermore, weather elements like hailstorms, strong winds, and humidity may damage them further.


Solar panels are low maintenance. Solar panels offer many advantages, from savings potential and environmental protection to environmental preservation. To extend their lifespan, it is important to take good care in maintaining them. Debris that gathers on solar panels can block sunlight as well as scratch or chip them over time causing them to break. It’s best to clean your solar panels regularly or install solar critter guards.


3 Tips to Help Your Solar Panels Last Longer

You’ll want to make sure that your best solar panel investment will last for as long as you can. Here are some tips on how to ensure your solar panels last as long as possible:

1. Cleaning and Maintenance

Solar panels that are clean will absorb more sunlight, and therefore work better. Some solar panels require weekly cleaning, while others can be cleaned every two months. The frequency of cleaning solar panels is determined by where you live.

2. Regular Maintenance and Servicing

Solar panels last longer when they are maintained. Solar panels that aren’t regularly cleaned and don’t receive routine maintenance are more likely to degrade.

3. Installation

The location of the solar panels, how they are installed and even the rack system can affect the degradation rate. It is important to pay attention to your solar panel installation, and to any possible threats, such as low tree branches.


Solar Equipment Warranty

The warranty of your solar panels will also affect how long they last. The warranty on most solar panels is 25 years and covers any problems or defects that occur during this time. It is important to remember that the warranty does not cover damages caused by negligence or improper installation.


When Should I Replace My Solar Panels?

If your panels don’t produce enough electricity to cover your bill, it is time to replace them. Solar panels have improved in recent years. It is possible that an older model has degraded more quickly than the current industry standard.

Use an app or a physical tracker to monitor the amount of electricity that your solar panels generate. This can help you determine how quickly they are degrading. It’s not necessary to replace your solar panels just because the output has decreased. However, you may want to begin saving for replacements in the future.

Solar panels can be a costly investment that homeowners don’t make lightly. You can extend the life of your solar panels by doing some research on their lifespan and following a few simple maintenance steps.

Florida Solar FAQs

Do solar panels need maintenance?

Solar panels require maintenance just like any other home appliance. It should still be manageable. It is important to clean and inspect solar panels periodically and to monitor their performance.

How can you extend the life of your solar panels?

Solar panels are no different. You’ll want them to last as long as possible, just like any other home system or appliance. You can make sure your solar power system works properly for many years by following a few simple steps.

Why do solar panels degrade over time?

Solar panels degrade naturally by 0.5% to 3.0% annually due to factors like thermal cycling, damp heat, and humidity freeze, as well as UV exposure.


Final Thoughts – How Long Do Solar Panels Last in Florida?

Solar panels in Florida should last between 25-40 years depending on their type, manufacturer, installation quality, and regular maintenance. A warranty and regular upkeep can help extend their lifespan. Research your options before installing panels from reputable installers/manufacturers for best results.
