Reasons Why Solar Panels Degrade

Businesses and homeowners around the world are slowly getting more attracted to making their life more sustainable by using solar energy. It helps to understand the average lifespan of solar panels to figure out whether it’s well worth the investment.  

25 years is the average lifespan of solar panels. But, this does not mean that they will stop generating energy after a couple of years. It simply means that after 25 years, their production of energy may lower beyond its guaranteed rated production output.  

Today, we are going to share with you some common reasons why solar panels Plano degrade over time. 


You should think about the average temperature of your current area if you are thinking about installing solar panels. The truth is that excess heat can lower the production of energy. You should take time to arrange the panels in a way that enables enough airflow to keep them at the best temperature for optimum operating conditions.  

Solar Irradiation 

For solar panels to operate properly and generate sustainable energy, sunlight is required. Almost every individual have a misconception that it is the heat from the sun that enables the PV cells to generate the electricity. Well, the truth is that the power generation is related directly to the number of UV rays that hit the panel. 

Mounting Position 

Solar panels work based on how much solar energy they can collect. You’ve got to ensure it is installed facing the sun as much as possible to improve its efficiency.  The different roof surfaces on your home will absorb various amounts of sunlight at various times as the sun moves throughout the sky across the day. Thus, the way the system is mounted at a single installation location will have an impact on the production of energy. The best orientation for solar panels depends on where you are located. For instance, if you live in Texas, the best orientation is facing the panels south at an incline that complements your location’s longitude. This will help achieve the best solar exposure across the day.  


Furthermore, the weather also has a huge part in the panels’ longevity. A strong wind can cause branches of trees to fall on panels and potentially damage the anti-reflective glass coating that covers the solar panels. Heavy snow can accelerate degradation and cause panels to lose their structural integrity. Huge hailstones can damage the glass. But, almost every panel from the manufacturer is certified and tested to endure such elements.  

Installation Problems 

You have to think about a couple of vital features if you want to improve your solar panel’s lifespan. Solar panels aren’t susceptible to defects and are made for durability. But, you have to be particularly careful when first installing and connecting panels. Because of this, it’s vital to hire a professional installer. The professional solar panel installer will have to consider the condition of the roof and the connection system when arranging the solar panels in arrays. A leaky, damaged, or old roof can cause severe issues down the line if an installer does not properly check these conditions.
