Product Manufacturing Process

The manufacturing process of PV panels involves multiple steps to ensure high efficiency and durability. Initially, high-purity crystalline silicon is produced through a process of purification and crystallization. Monocrystalline silicon cells are made from a single crystal structure and are more efficient, whereas polycrystalline cells are made from silicon crystals melted together, offering a balance between cost and performance. The cells are then treated with an anti-reflective coating to maximize sunlight absorption. Encapsulation involves sealing the cells with EVA (ethylene-vinyl acetate), protecting them against mechanical stress and environmental factors. High-transparency, low-iron tempered glass is used for the front cover to protect against weather while ensuring maximum light transmission. The back sheet, typically made from durable polymers, safeguards the panel's rear side. Electrical connections are facilitated via a junction box that includes bypass diodes to maintain efficiency. Finally, the entire assembly is framed using black anodized aluminum, providing structural integrity and ease of installation. This meticulous manufacturing process ensures that PVSTAR panels deliver long-term performance and reliability. (Reference: [Authoritative paper on PV manufacturing process)
