Do solar panels age?

The service life of the solar cell version is determined by the material of the cell, tempered glass, EVA, TPT, etc., and the service life of the panel made by the manufacturer who will generally use a little material can reach 25 years, but with the impact of the environment, the material of the solar panel will age with time. In general, the power will be attenuated by 30% after 20 years of use, and 70% after 25 years.

Solar panels generate electricity by converting solar energy into electricity, and the panels will age during long-term use. The main reasons for the aging of solar panels are as follows:
1. Excessive use: If the solar panel is in a high-load working state for a long time, it will cause a large fluctuation in voltage and aggravate the aging of the board.
2. Affected by the weather: Solar panels generate electricity by absorbing sunlight, but if they are exposed to too strong ultraviolet radiation in a bad weather environment, it will cause cracks and discoloration on the board surface, thereby reducing the power generation efficiency.
3. Quality problems: Since solar panels are used for a very long time, they must have durability and quality assurance to be able to exert the best power generation effect. If the production or installation process is not rigorous, it will lead to the occurrence of solar panel quality problems and aging.

4. Thermal stress: Solar panels will experience repeated thermal expansion and contraction under the temperature difference between day and night and seasonal temperature difference, which may lead to the generation of microcracks, and then affect the electrical properties of the panel.

5. Sunlight can age solar panels: Solar panels age because of constant sunlight. The panel's power will drop first. Then, it will stay at a lower level.

6. Materials Have a Finite Life Cycle: The materials used to create solar panels can degrade due to exposure to sunlight over time. This deterioration affects the efficiency of solar panels.

7. Manufacturing Quality of Solar Panels is Important: If the manufacturing of a solar panel is poor, such as fractured ordering, improper soldering, damaged PCB, and/or broken packaging, then that solar panel is not going to last long.

Here's how we're making solar panels last longer and work better:

Two-Sided Panels: These panels catch sunlight that bounces off the ground, which can help make 10–20% more power. And they're made to last.
Smart Monitoring: We use AI to find early warning signs of trouble. This lets us fix problems before they get too bad.

Dirt-Rejecting Coatings: The backside coating, which is applied to solar panels, allows dry weather to naturally remove the dust and dirt on the backside, preventing the dust from blocking the sun and the generation of sun energy power, thus preventing the production of electric power from solar energy.
