- Request factory audit and test reports if needed
Product Overview
Monocrystalline PERC (Passivated Emitter and Rear Cell) solar panels manufactured by top-tier Chinese solar module producers. These 550W modules use 144 half-cut monocrystalline cells (182mm M10 wafer size) with multi-busbar (MBB) technology for improved current collection and reduced resistive losses. Half-cut cell design reduces operating temperature and minimizes hot spot risk while improving shade tolerance. The modules feature a 2.0mm anti-reflective coated tempered glass front sheet, durable EVA encapsulation, and a lightweight anodized aluminum alloy frame rated for 5400Pa snow load and 2400Pa wind load. Compatible with all standard mounting systems and inverters. Suitable for on-grid and off-grid solar systems, solar farms, commercial rooftops, carports, agricultural PV, and hybrid installations. China's solar panel exports surged 80% YoY in 2026, and Chinese Tier-1 manufacturers supply 80%+ of global solar module demand with competitive pricing, fast lead times, and bankable warranties.
