Solar energy is currently the cleanest and most economical source of power. Whether it’s homes or industries, solar panels are being installed everywhere. After installation, it’s just a matter of time before the sun rises. As soon as sunlight appears, they start working. Another special feature of solar panels is that they can easily last for 20-25 years. If properly maintained, this lifespan can be further extended. Today, we’ll explain the reasons why panels can fail and what measures need to be taken to ensure their longevity.
The typical lifespan of solar panels is 25-30 years. This depends on the quality of the panel, usage, and maintenance. Many high-quality panels continue to perform well even after their warranty expires. If properly maintained, panels can generate electricity for over 30 years.
There are many reasons for panel failure. The most common is dust accumulation on the panel. This reduces the efficiency of the solar panel. In urban areas, pollution and moisture combine to form a thin layer on the panel surface. This forces the panel to work extra hard to generate power. If this condition persists for a long time, it impacts the panel’s efficiency and lifespan. Weather is also a major factor; high temperatures reduce panel efficiency, and excessive humidity and rain can cause rusting of metal parts.
Heavy storms and rain can also cause small cracks in the panel. Similarly, faults in installation and wiring can also disrupt performance.
Clean solar panels 2-4 times a year. Cleaning and inspection are especially important after stormy weather.
If a tree is casting a shadow on the panel, trim it.
Do not install the panel by gluing it to the ceiling. Maintain a distance of 1-2 feet between the ceiling and the panel to maintain ventilation.
Have your solar energy system inspected by a professional technician at least twice a year.
