A Comprehensive Guide to Solar Power Panel Longevity

When individuals make significant investments, whether in a car, computer, or refrigerator, their expectation is that they won't have to replace the item in the near future. Thankfully, for homeowners and business proprietors contemplating the installation of solar power panels, there's reassurance in knowing that while these panels aren't immortal, they are engineered to provide several decades of dependable electricity generation. Before making a decision on whether to adopt a solar energy system, it's essential to understand the lifespan of solar panels. Sunsent Solar tells you what you should know in this blog post.

The Lifespan of Solar Power Panels

Like all technological devices, the longevity of a solar panel is influenced by various factors, such as climate conditions and the quality of the installation. In general, you can anticipate solar panels to maintain a satisfactory level of electricity generation for approximately 25-30 years. During this period, the panels typically operate at their highest efficiency and are protected by a 30 year warranty. Nevertheless, they may remain functional well beyond their 30th year. As time passes, the panels will experience a decline in performance, leading to a decrease in electricity output.

Factors That Make a Solar Panel Degrade

Debris Impact

The impact of falling debris, such as large tree branches during severe weather events like hurricanes or tornadoes, can result in surface damage to solar panels.  

Temperature Variations

Solar panels are engineered to function effectively in diverse climates, but abrupt and extreme temperature fluctuations, from excessive heat to cold, can impact the integrity of panel components.

Inadequate Installation

Solar panels can incur avoidable damage if they are not correctly positioned at optimal angles or securely fastened by an installer during the installation process. Make sure to choose a reputable solar company when switching to solar power, to ensure that your panels are installed correctly.

Humid Conditions

Prolonged exposure to elevated humidity levels in conjunction with high temperatures can lead to the deterioration of solar panels.

Making Your Solar Panel Last Longer

While it's impossible to guarantee the eternal life of your solar panels, providing some additional care periodically can extend their ability to generate ample electricity for as long as possible. These straightforward measures can help enhance the longevity of your solar panels:

·     If you suspect any issues, consult a professional for panel inspection and potential repairs, rather than attempting DIY fixes that could void the warranty.

·     Prevent prolonged accumulation of heavy snow cover on your panels.

·     Regularly assess the performance of your panels.

·     Ensure that your panels remain free from dirt and debris, such as leaves.

The End of a Solar Panel’s Lifespan

You can continue using a solar panel well beyond its expected lifespan as long as it meets your electricity needs to your satisfaction. However, when you find that your solar panels no longer meet your energy production requirements, you can retire and replace them, knowing that you've received significant value from your initial investment. Your solar panel installers will provide guidance on how to properly dispose of the old panels.
