Solar panels can help you cut costs and save energy. However, installing solar panels is a costly investment, which is why it may be necessary to find out their durability before spending your money. Also, it is only natural to want to invest in something that will serve you in the long-term. So how long will solar panels last? Read on to find out the longevity of solar panels to help you make an informed decision.
Determine Longevity of Solar Panels
Generally, solar panels can last anywhere between 30 and 50 years. As such, most manufacturers offer a warranty of around 25 years or more. Unfortunately, their performance reduces over time, leading to degradation (reduction in output). Note that solar panels degrade at a rate of 0.5% per year.
So how long will solar panels last? To help you establish the lifespan of your solar panels, below are factors that play a critical role in their durability.
1. Weather
Extreme weather can reduce the lifespan of your solar panels by causing damage and accelerating degradation. Hailstones can damage the glass on your solar panels, while snowfall speeds up degradation by causing the panels to lose their structural integrity. Similarly, strong winds or windstorms can lead to falling branches that land on solar panels and damage the glass coating.
2. Installation
The installation of your solar panels can affect their durability. Proper installation can lead to a longer lifespan, while poor installation can reduce it by 25%. What’s more, substandard installation services can cause solar panels to generate less power than they should. With this in mind, only work with solar installation professionals who are experts in their field and can get it right the first time.
3. Quality
The higher the quality of your solar panel, the longer it will last. Critical components like the mounting system, solar cells, and encapsulation system should be of high quality to prevent deterioration. Although lower quality solar panels can help you cut costs, they degrade much faster. You are better off investing in high-quality products that will give you value for your money and serve you longer.
4. Maintenance
Like any other valuable equipment, solar panels require good care and maintenance to last long. When you ignore your solar panels, they can get damaged and degrade much faster.
