The service life of household solar panels excludes force majeure natural disasters and human factors, and is used according to normal conditions. According to the current user's normal use feedback, there will be differences due to different types of solar panels.
The specific theoretical lifespan is 25 years for tempered glass laminated encapsulated solar panels, 5-8 years for PET laminated encapsulated solar panels, and 2-3 years for glue-encapsulated solar panels. More than 95% of the solar panels on the market are solar panels that are laminated and packaged with tempered glass.

The life of a photovoltaic module is determined by its power generation efficiency, and the degree of bonding of the PN junction and the purity of the silicon wafer determine the strength of the solar panel to generate electricity under the same light. Over time, the PN junction will continue to break. , so the efficiency will continue to decline, the conversion efficiency will be more than 90% after 15 years, and will drop to about 85% after 25 years, so the life of photovoltaic components is basically more than 20 years.
