The core of photovoltaic products is solar panels. At present, there are two main types of semiconductor materials used for power generation. Single crystal silicon and polysilicon have been actively promoting the application of renewable energy in recent years. The solar street light industry has developed rapidly.

There are two factors that affect the life of solar photovoltaic boards:

1. Internal battery departure welding; Due to the unreasonable spacing design of solar battery films or poor welding quality, the temperature difference between the module during the day uses thermal expansion and contraction between the welding belt and the battery Essence

2. The cool place is definitely a natural enemy of solar panels; if a small part of the solar panel is blocked, sometimes the solar energy on all other panels will stop working. The solar cells on the solar panel are connected in series, and keep working normally at the current level of the weakest battery. If some batteries on the solar panel are blocked, it will affect the normal output of other batteries.
