How Long Does Solar Panels Last

What Are The Types Of Solar Panels, How Long Does Solar Panels Last

The cost for solar panels is significant, even though the federal income tax credit or additional rebates and incentives may reduce the costs. Solar panels are designed to last for decades.

It’s crucial to consider the lifespan of solar panels when you do your research on this renewable energy source. Industry standard is for solar panels to last 25-30 years. Most reputable manufacturers offer 25-year or longer production warranties.

Solar panels typically break even six to ten years after installation. You will save thousands of dollars over the lifespan of the solar panels if the panels continue producing at high levels for an additional 15 years.

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, etc. Solar panel warranties do not cover racks for solar panels. They may be damaged by weather elements.

Solar inverters last between 10 and 15 years. The inverters work so hard to convert solar energy into electricity that can be used by your home. Solar inverters are typically replaced for $1,000 – $2,000.

What Solar Panels Last the Longest?

The quality of a product is one of the most important factors in determining how long solar panel will last. The solar panels on the market can be classified into three categories: Tier One (the most expensive), Tier Two (the second-most expensive) and Tier Three. Tier One manufacturers are those who have produced solar panel for at least five years and have stable finances. They also have high ratings for their service and product quality.

In addition to having higher standards, Tier One solar panels have often a higher production after 25 years compared to Tier Two and Tier Three panels. The degradation rate of Tier One solar cells is 0.30% per year, compared to Tier Two’s 0.50% and Tier Three’s 0.80%. Tier One solar panel are generally expensive upfront (between 10% and 30%), but it is highly likely they will be recovered over time.

A study by the National Renewable Energy Laboratory shows that the average degradation rate for all solar panels is 0.50%. After 25 years, you can expect to get about 89% the original solar output.

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.

The efficiency of solar panels will naturally decrease over time due to factors such as sunlight exposure, temperature fluctuations and humidity, mechanical stress, and the quality and manufacture of materials. Most solar panel degrade at a rate of 0.5% per year on average. After 25 years of this gradual power loss, the solar panel is expected to have around 87.5% its original efficiency.

Solar panels are subject to degradation, but advances in technology have made them more reliable and durable with a reduced degradation rate. 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.


The breakdown of solar panel Tiers reveals that the quality of the panel has a major impact on the long-term output. Look at the warranty provided by the manufacturer to get an idea of the output you can expect. If a company offers a warranty of 25 years or more, they are likely to stand behind their product for a very long time.


You can be confident that your solar panels will last a long time if you work with an experienced installer. Your solar panel could degrade more quickly if they are not properly installed and wired. Many of the top solar companies offer maintenance checks in order to ensure that the system is working properly and to detect any problems before they become larger.


The climate in which you install solar panels will have a significant impact on the performance and lifespan of the panel. You should therefore be aware of the impact of weather conditions and other variables on your solar panel’ efficiency and lifespan.


Solar panels are low maintenance. They offer a lot of benefits including the potential for savings and environmental protection. To extend the lifespan of your solar panel, you can take good care of them. Debris that builds up on solar panel can not only block the sun’s light, but also scratch and chip the panel, causing them to break. It’s best to clean your solar panel regularly or install solar critter guards.

Three 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 panel last as long as possible:

1. Cleaning and Maintenance

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

2. Regular maintenance and servicing

Solar panels last longer when they are maintained. Solar panel 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 any possible threats that may be around it, such as low tree branches.

Solar Panels: Standard Warranty & Guarantees

If you are looking to purchase a solar power system, you will want to make sure that it is reliable and can produce the electricity you need. Standard warranties and guarantees are important to ensure that your investment in solar panel is worth it.

Most solar panel owners qualify for a standard guarantee on their panel. These warranties provide a basic level of protection, and cover any defects or damages that may occur during the warranty period. Some reputable manufacturers of solar panel offer warranties that can last up to 25-years. This gives homeowners the peace of mind they need to know their solar energy system is going to continue performing optimally for many years to come.

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 panel 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 panel generate. This can help you determine how quickly they are degrading. It’s not necessary to replace your solar panel just because the output has decreased. However, you may want to begin saving for replacement panels in the future.

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