Do Solar Panels Need Replacing?

Solar panels only need replacing when they are broken, damaged, and can not produce energy. Without these problems and difficulties, you don’t need to replace a solar panel.

Solar panel manufacturers provide 25 to 30 years of warranty and guarantee with a high-quality solar panel.

The warranty period is divided into two sections. The first 10 or 15 years warranty covers the power production that means a warranty of efficiency.

You will get the next 25 to 30 years of warranty coverage including the panel and body warranty.

If your solar panel can not produce sufficient power and the degradation rate is higher than that of the standard rate, it will be better to replace the solar panel.

Similarly, solar panels are outdoor units and they can be damaged due to extreme blow or hit. You can replace the solar panel when the physical condition is damaged.

Lifespan of a Solar Panel

If you consider the end of the life of a solar panel when it will be unable to produce electricity, the lifespan of a solar panel is approximately 20 to 30 years. There is a 5 percent degradation rate per year of any solar panels.

Do You Need To Replace Solar Panels?

What Affects Solar Panel Lifespan?

Solar panel lifespan can be affected by different things. First of all, you have to consider the external and internal conditions of a solar panel separately.

You know that the external part covers the physical body. Snow, ice, hot weather, humidity, and dust can affect the body of the solar panel.

On the contrary, the internal part that means efficiency can be lost for high power devices, solar panel components, and voltage differences with higher discharging.

Snow, rain, or humidity can not affect the solar panel’s surface instantly but it will reduce the efficiency and productivity over time.
