There are many factors that affect the reliability of solar panel # solar panel #. Solar panel manufacturers provide a product warranty and a performance warranty of 10 and 25 years (typically for the lifetime of glass solar panels), respectively. Performance guarantee refers to the guaranteed period of time during which the solar module will operate at or above the stated power. The following are the factors that affect the reliability of solar panels:
Photoinduced degradation
When solar modules are exposed to light, they face a phenomenon known as photoinduced degradation or more common LID. In most cases, due to the presence of oxygen, we will see this effect in crystal modules during the silicon ingot manufacturing process. During the doping of solar cells with boron, this oxygen can lead to reduced electron motion. This resulted in a loss of up to 3% of electricity generation in the first few days.

Other climatic conditions, such as humidity, solar irradiance, sand and dust
When solar modules are exposed to fluctuating levels of solar intensity and humidity, the ultraviolet radiation portion of the irradiance can cause chemical reactions and degradation processes inside the polymer and outside the photovoltaic module. Humidity can have a negative impact on the functionality of the polymer, leading to delamination of the entire photovoltaic module. In addition, moisture can cause corrosion of solar cells, which can further reduce power output. Although it mainly depends on the location of the photovoltaic system, it has been observed that the power output can be reduced by up to 40%. In addition, dust storms can damage the AR coating like a wear mechanism, and can lead to the formation of an ultra-thin layer of concrete on the components.
