The service life of solar panels is a complex issue, which is influenced by many factors. In general, the service life of solar panels can reach 20 to 30 years, but the specific life length will depend on many aspects. The following is a detailed analysis of the factors that affect the service life of solar panels:
First, material quality
Battery: The battery is the core component of the solar panel, and its quality directly affects the performance and life of the panel. Panels that use high-quality batteries generally have a longer service life.
Tempered glass: protect the battery to prevent the damage of the external environment to the battery. High-quality tempered glass has higher light transmittance and weather resistance, thus extending the service life of the panels.
Packaging materials: such as EVA (ethylene-vinyl acetate copolymer) and TPT (backplane), the quality of these materials also determines the durability and stability of the panel. Panels that use high-quality packaging materials tend to last longer.
Second, manufacturing process
Production process: The fine manufacturing process can reduce the loss of materials and the aging rate of the panel, thereby extending its service life.
Quality control: Strict quality control system can ensure that every panel meets the quality standards, reduce the rate of defects, and improve the reliability and service life of the panel.
Third, environmental conditions
Light intensity: Appropriate light intensity can improve the power generation efficiency of solar panels, but too strong light may also cause damage to the panels. Therefore, when installing solar panels, it is necessary to choose a suitable location to avoid long-term exposure to strong sunlight.
Temperature: High temperature will accelerate the aging and damage of the panel, shorten its service life. Therefore, when installing solar panels, it is necessary to choose a location with good ventilation and avoid long-term exposure to high temperatures.
Humidity, wind, sand, rain and snow and other harsh environments: these environmental factors will also cause damage to solar panels and shorten their service life. Therefore, when installing solar panels, you need to take appropriate protective measures, such as installing rain cover and air filter.
Fourth, installation and maintenance
Installation location: Solar panels should be installed in a location with sufficient light, good ventilation, and avoid long-term exposure to harsh environments.
Installation Angle and orientation: Adjust the installation Angle and orientation of solar panels according to local latitude, season and other factors to obtain the maximum amount of sunshine.
Regular maintenance: Regularly check whether the surface of the solar panel is clean, there are no signs of damage or aging, and timely treatment. For example, clean the snow and dust on the surface in time to prevent it from causing damage to the panels.
Fifth, power attenuation
Solar panels in the process of use, its power will gradually decay. According to some data, after 20 years of use, the power of solar panels may decay to about 80% of the original; After 25 years of use, the power may decay to 70% or less of the original. This power attenuation is a normal physical phenomenon, but it will affect the power generation efficiency and service life of the panel.
Sixth, encapsulation
Different packaging methods also affect the service life of solar panels. For example, the life of tempered glass laminated solar panels is 25 years, while the life of PET laminated solar panels is 5-8 years, and the life of drip glue packaged solar panels is 2-3 years. Now more than 95% of the solar panels on the market are tempered glass laminated packaging.
Seventh, other factors
Use: The way solar panels are used also affects their service life. For example, frequent switching on and off, overload use, etc., may cause damage to the panel.
Storage conditions: If the solar panel is not used for a long time, it needs to be properly stored to avoid long-term exposure to the harsh environment.
In summary, the service life of solar panels is the result of a combination of factors. In order to extend the service life of the panels, it is necessary to choose high-quality materials and manufacturing processes, ensure good use environment and conditions, and carry out correct installation and regular maintenance. Only in this way can we give full play to the efficiency of solar panels and bring more convenience and environmental benefits to our lives.
