6 Factors Affecting The Lifespan Of Solar Panels & Its Solution

The lifespan of Solar panels ranges from 25 to 30 years on average. Homeowners and businesses across Nigeria are becoming more interested in living a more sustainable lifestyle. Going solar is the best way to transition to clean, sustainable energy while also drastically reducing — or even eliminating — your monthly utility bills for good.

To get the most out of your solar panel installation, you should first understand the average lifespan of solar panels and decide whether a solar power system is a good investment for your home or business.

In this section, we’ll go over how to extend the lifespan of solar panels, what maintenance is required, why degradation occurs, and other factors that affect solar panel lifespan or limit their efficiency and performance.

6 Factors Affecting The Efficiency and Lifespan of Solar Panels

When it comes to technology, there is no such thing as perfection. Here are some of the factors that may have an impact on the efficiency or performance of your solar panel system.

1. Position Of Mounting

Solar panels work by absorbing as much solar energy as possible. Installing your panels so that they receive as much sunlight as possible will increase their efficiency as well as increase the lifespan of solar panels. As a result, mounting is an important factor to consider when it comes to energy production.

Roof solar panels absorb varying amounts of sunlight as the sun moves across the sky throughout the day. However, in general, south-facing is the best orientation for all-day solar exposure.

2. Irradiation From The Sun

Most people believe that the sun’s heat causes photovoltaic (PV) cells in solar panels to generate electricity. In fact, sunlight is required for solar panels to function properly and produce sustainable energy. The amount of power generated by solar panels is directly proportional to the amount of sunlight (UV rays) that fall on the panel.

3. Temperature

Before installing solar panels on your home or business, you should consider the average temperature in your area as this negatively affects the lifespan of solar panels.

Excessive heat can reduce the energy production of your system. Considering your area’s climate will assist you in arranging your solar panels in a way that allows for adequate airflow, keeping them at the proper temperature for optimal operating conditions.

4. Quality

The quality, materials, and type of solar panels you install, as with most things, will influence how well they work and how long they last. While low-quality materials may be less expensive, they may also degrade faster.

5. Degradation

For a variety of reasons, solar panels may degrade faster than expected. When solar panels are exposed to extreme changes in climate, heavy soiling, or improperly installed, crystalline silicon panels may degrade at a faster rate. The superiority of the technology used by various manufacturers can also play a role. This ultimately affects the lifespan of solar panels.

6. Maintenance

Solar panels, like anything else of value, last longer when properly maintained. Panels may degrade faster if they are dirty, have debris on them, or are not regularly maintained.

3 Tips to Extend The Lifespan of Solar Panels At Home

Solar panels are great because they require very little maintenance. Unless your area is highly susceptible to dust, dirt, pollen, or sand due to an arid climate, regular solar panel cleaning is generally unnecessary.

While solar panels generally require little maintenance, it is still necessary to inspect and monitor their performance on a regular basis. Here are a few pointers to make sure your solar installation is performing optimally:

Tip #1: Keep Your Panels Free Of Debris And Other Potentially Harmful Materials.

The accumulation of dirt, pollen, leaves, and bird droppings can reduce the efficiency of your solar panels. 

While rain is usually sufficient for cleaning your panels, you may want to consider hiring a professional if you notice your panels aren’t working to their full potential. 

You should also avoid placing your panels under branches because not only will the shade reduce output, but the branches may fall during a storm and cause serious damage.

If any of these elements obstruct or damage your panels, and you lack the necessary training or equipment to take action, contact your solar provider immediately for assistance.

Tip #2: Make Sure Your Panels Are Being Monitored And Maintained On A Regular Basis.

Regular maintenance checks will help keep your solar system’s panel performance, meters, inverter, and other components operating at peak efficiency. It’s also critical to keep track of any changes in your electric bills and energy consumption.

If your solar panels are underperforming after rainfall or being hosed down with water, or if you notice an unusual spike in your utility bill, it could be a sign of an electrical problem that requires professional attention.

Tip #3: Collaborate With A Reputable Solar Provider.

Finding a reputable solar installer is the best thing you can do to ensure the longevity of your solar system. Although solar systems require little routine maintenance, some solar providers offer comprehensive maintenance packages for the life of their products to ensure they continue to generate clean, affordable, and dependable energy for decades.

Sunrun has over 20 years of installation experience and works with only the best installers in your area to provide you with worry-free energy.

We strongly advise you to contact your trusted solar provider for professional assistance if your panels require more than a routine hosing down or if you need to get on the roof.

After 30 Years, What Happens To Solar Panels?

Even if your solar system has reached the end of its expected life, it can still produce energy and save you money. 

Manufacturers determine that a solar panel’s “useful life” ends when its output falls below 80% – but that doesn’t mean it’s useless. The panels will continue to generate energy for many years, albeit at a lower efficiency.

Degradation is an unavoidable byproduct of owning solar panels. Nothing lasts forever, but the savings generated by your solar system over its useful life can be saved or reinvested in your business. Some of our customers achieve payback in as little as five years, giving them two and a half decades of free electricity.

Frequently Asked Questions About The Lifespan Of Solar Panels 

How Often Do You Replace Solar Panels?

Solar panels typically last 25 to 30 years. Most reputable manufacturers provide 25-year warranties. Six to 10 years after installation, solar panels break even.

Is Maintenance Required For Solar Panels?

Solar panels require little maintenance, so you can usually leave them alone. Light cleaning is all they need to keep dirt, leaves, and other debris from blocking the sun’s rays.

What Is The Highest Lifespan Of Solar Panels?

The highest solar panel lifespan is 30 years.
