At present, the core material of solar panels is crystalline silicon (monocrystalline silicon and polycrystalline silicon), accounting for over 90% of the market share and remaining the long-term mainstream substrate. Its core raw material is solar-grade polysilicon (purity 6N-9N), refined from industrial silicon, and China has achieved full industrial chain independent control of this material.

The module line is also called the encapsulation line. Encapsulation is a key step in solar cell production — no matter how good the solar cells are, high-quality modules cannot be produced without excellent encapsulation technology.

Encapsulation not only ensures the service life of solar cells but also enhances their impact strength. High product quality and long service life are the keys to customer satisfaction, so the encapsulation quality of solar modules is very important.

Driven by global energy transition and technological innovation, solar panels have broad development prospects, showing clear trends in technology upgrading, scenario expansion and market growth.

Application scenarios are becoming more diversified, evolving from traditional rooftop and ground power stations to building-integrated photovoltaic (BIPV), agriculture-photovoltaic complementarity and other integrated modes, realizing in-depth integration with various industries.
