How Long Do Solar Panels Last? 7 Tips To Extend Their Life

in Renewable Energy by

There has been a growing trend in adopting renewable energy sources in recent years. One is solar power, which gained acceptance in various industries, commercial establishments, and even homes worldwide. 

As solar technology becomes readily available, it allows the transition to a readily available power source. Solar panels are a crucial source of clean energy for homeowners. It’s an option worth considering if you want to save energy and power appliances. 

The Lifespan Of Solar Panels 

Knowing everything about solar panels is crucial if you plan on switching to solar power for your home. The lifespan of solar panels is an essential factor to think about. 

Generally, it can last between 25-30 years, depending on the manufacturer, usage, and location, to name a few. However, it doesn’t necessarily mean the solar panels will die out once they reach the 25-30 range. Instead, the power the panels generate will eventually decline in the coming years as they start to degrade. 

Tips To Extend The Lifespan Of Your Solar Panels 

If you want to gain the most value from your solar panels and ensure they last as long as possible, performing routine solar panel maintenance is crucial. 

An advantage of solar panels is that they require minimal maintenance to function properly and generate solar energy.

1. Regular Cleaning 

The basic maintenance chore is regular cleaning. Expect the steady accumulation of debris, dust, and dirt on the solar panels, especially during storms or prolonged periods without rainfall. Performing occasional cleaning can eliminate this debris and ensure the panels get optimal sunlight. 

If you handle the cleaning task, carefully remove any debris from the surface of the panels. Make sure that no sharp objects, such as rocks or other materials, can potentially damage them. 

Make it a priority to inspect the panels at least once every few weeks during the spring and summer. Remember that it’s during these seasons that issues are likely to occur. For those living in areas with snow, brush it off before it melts. If you leave the snow on the panels, the damage is likely once the ice forms and presses on the surface, resulting in cracks. 

2. Schedule An Annual Inspection 

If you want to ensure the solar panels function optimally, schedule a yearly inspection. A professional will inspect the panels and ensure they normally work during an inspection. You can also schedule a routine check if necessary if you notice an issue with the solar panels or if they’re not generating enough energy as usual.

3. Check For Signs Of Damage 

Solar panels are built to last, but damage can happen if constantly exposed to severe weather conditions or physical impact from debris. Make it a priority to inspect the solar panels for any indications of warping, cracking, or other types of damage. 

If you find any damage, get in touch with a professional to carry out the necessary repairs immediately to avoid further deterioration. 

In one scenario, there should be no gaps in the panels since it allows debris or dust inside that can damage the key components. Sadly, it diminishes efficiency and reduces the panels’ lifespan. 

4. Protect The Solar Panels During Severe Weather 

Protecting your solar panels from damage is also essential so they can last for years. Cover the panels with a tarp during severe weather conditions to protect them from rain, hail, snow, and sleet. Stay up to date with the weather forecasts if there’s upcoming severe weather heading to your location. Doing so allows you to take the necessary precautions in advance. 

5. Utilize A Backup Battery 

If you want to maximize your solar panels, consider investing in energy storage in the form of batteries. When you have a battery, it allows energy utilization at night when sunlight is no longer available. 

A backup battery will come in handy, especially during a power outage. Power outages in your home are no longer a concern. It also helps lessen the load on your solar panels, helping prolong their lifespan. 

6. Apply A Protective Coating Every Few Years 

Aside from protecting your solar panels from the elements, consider applying a protective coating. The purpose is to maintain the appearance and prolong the durability of solar panels. 

One of the main concerns is the formation of rust. As corrosion develops, it steadily degrades the metal components, shortening the panels’ lifespan. The protective coating helps prevent this issue. Generally, the coating serves as a physical barrier against the elements, adding a layer of protection for years. 

7. Obtain A Performance Warranty 

The majority of solar panel manufacturers offer a performance warranty with their products. Generally, the warranty will guarantee a certain level of output from the solar panels over a specified period, usually within 10-25 years, depending on the solar panel type you plan on investing in. You’re entitled to a replacement or refund if the solar panels fail to meet the indicated output. 

Although solar panels have a limited lifespan, proper care, and maintenance can provide you with power for years. With the performance warranties, you have peace of mind knowing your investment is protected. 

Final Thoughts  

Solar panels are a practical investment for your home if you’ve long wanted to switch to a renewable power source. As a cost-efficient and environment-friendly option, it can supply clean, renewable energy for years. By providing your solar panels with proper care and maintenance, and protection from severe weather and damage, you have a good energy source for years to come.
